LEPTOSPIROSIS – ARE YOU AT RISK?
What is Leptospirosis?
Two types of Leptospirosis affect people in the U.K.
Weil’s disease. This is a serious infection that is transmitted to humans by contact with soil, water or sewage which has been contaminated with urine from infected rats.
Hardjo-type Leptospirosis which is transmitted from cattle to humans.
What are the symptoms?
Both diseases start with a flu-like illness with a persistent and severe headache, muscle pain and vomiting. Jaundice appears about the fourth day of the illness.
How might I catch it?
The bacteria can enter your body through cuts and scratches and through the lining of the mouth, throat and eyes.
How can I prevent it?
After having worked in sewage or anything contaminated with sewage, wash your hands and forearms thoroughly with soap and water. If your clothes or boots are contaminated with sewage, wash thoroughly after handling them.
Take immediate action to wash thoroughly any cut, scratch or abrasion of the skin immediately. Apply antiseptic to the wound, cover with cotton wool or gauze, and protect with a waterproof plaster.
DO NOT handle foot, drink or smoking materials without first washing your hands.
If you contract the symptoms described after coming into contact with sewage, report to your doctor immediately and advise him/her of the circumstances.
Sewage gases are potentially explosive and toxic. DO NOT enter any of the below ground compartments of the PLATINUM 6..
Before carrying out any maintenance work, the equipment MUST be electrically isolated at the fuse box from which the compressor power supply is derived.
Do not leave covers open for any longer than necessary. Temporary barriers and warning signs should be erected around any open covers or man-ways as appropriate.
The end user is responsible for ensuring that proper provision is made under the Health & Safety Act, and due account is taken in respect of unauthorised access and vandalism. It is the end user’s responsibility to provide safe access for purposes of operation and maintenance.
The PLATINUM 6 is a packaged sewage treatment plant developed to serve a population equivalent of up to 6 people. This treatment plant comprises of: a primary settlement stage, a biological filtration zone and a secondary clarification zone.
The plant will provide long and trouble free operation provided the simple maintenance procedures are adhered to.
Your attention is drawn to the Health & Safety section in this manual. It is imperative that you read these instructions carefully before attempting to carry out any work on the system.
The plant has been designed to treat the volume and strength of sewage specified in the original quotation. To ensure that the plant continues to operate efficiently, your attention is drawn to the following points:
DO NOT EXCEED THE MAXIMUM DESIGN LOADING OF THE PLANT
DO NOT ALLOW SURFACE WATER TO ENTER THE SYSTEM
DO NOT ALLOW HIGH VOLUME DISCHARGES SUCH AS FROM SWIMMING POOLS OR JACUZZIS TO ENTER THE SYSTEM
DO NOT ALLOW LARGE QUANTITIES OF CHEMICALS SUCH AS WATER SOFTENER REGENERANT, DISINFECTANTS, STRONG ACIDS OR ALKALIS, OIL OR GREASE, PESTICIDES OR PHOTOGRAPHIC CHEMICALS TO ENTER THE SYSTEM
DO NOT USE CHEMICAL OR BIOLOGICAL EMULSIFIERS IN GREASE TRAPS

SCOPE OF SUPPLY
PLATINUM 6 UNITS
This comprises of a single tank containing the following components required for the sewage treatment process, the:
PLATINUM 6 Tank
Submerged Filter Beds
Air Diffuser Arrangement
The PLATINUM 6 tank is manufactured in glass reinforced plastic (GRP) and is supplied in a standard Emerald Green. It is completely impervious to water and sewage and has been designed to ensure a robust construction and a long service life. The tank is provided with one hinged access covers over the treatment zone.
The man-way cover is opened by rotating the Triangular public utility keys.
The submerged filter beds comprise many thousand of plastic pieces of filter media, randomly packed into the tank. The media is made from UV stable uPVC and provides a large surface area on which the bacteria required for the purification process can grow. The media is supported on a uPVC open mesh panel fixed above the base of the tank.
The humus zone settles out dead biological organisms (biomass) that have carried forward from the filter zone.
Please read the Health & Safety, section 1 of this manual before attempting to work on the system.
NOTE: The PLATINUM 6 tank should be stored with access covers closed to prevent accumulation of rainwater within the unit.
NOTE: Please refer to Installation Drawings, Section 8 of this manual.
The following instructions are offered for guidance only. Anua cannot accept any responsibility for incorrect off-loading or installation.
The contractor is responsible for off-loading all items of equipment with due regard to the following:
ONLY LIFT THE UNIT WITH CERTIFIED WEBBING STRAPS
DO NOT WRAP CHAINS AROUND THE UNIT
DO NOT LIFT THE TANK IF IT CONTAINS ANY WATER
DO NOT SUBJECT THE TANK TO SHARP IMPACTS
DO CHECK THAT ALL ITEMS DELIVERED CORRESPOND WITH THE PACKING NOTE
The PLATINUM 6 unit is provided with built-in lifting points on the inside of the turret and on some units additional eyes on the outside of the unit. These are NOT intended for transportation of the units. The lifting hooks should be connected to the tank lifting points by separate slings of equal length. Ensure that the slinging angle does not exceed 60o at the hook in order to eliminate excessive compressive loads on the side of the unit.
When working in deep excavations, make sure that all necessary safety precautions are taken to ensure the stability of the excavations and provide safe working conditions for site personnel. The only time anyone needs to be working at the bottom of the excavation is when levelling the base and ensuring that the first back-fill is correctly placed. It is the responsibility of the installer to determine the thickness and strength of concrete required to suit the ground conditions taking into account the buoyancy of the unit when being desludged, external forces exerted by the ground water, back-fill, traffic loading etc.
Siting the PLATINUM 6 Unit
British Standard BS:6297-1983 recommends that sewerage treatment works should be as far away from habitable buildings as is economically practicable. The direction of the prevailing wind should be considered in relation to any properties when siting the works. A small treatment works serving more than one premises incorporating conventional biological treatment should be a minimum of 25 metres from any dwelling. The sludge emptying contractors vehicle will probably have a maximum reach of 40 metres, but the depth from the ground level to the bottom of the tank must not exceed 5 metres.
The installation should be carried out in accordance with the requirements of the Construction and Building Regulations. An inspection chamber should be installed upstream of the PLATINUM 6. For sampling purposes a sampling chamber can be provided (optional extra).
During the course of the installation, the following minimum equipment will be required:
Normal construction equipment and plant
Concrete to C20P and semi-dry to 30mm sump to BS:5328
An adequate supply of water to fill the sump at the same rate as back-filling
De-watering equipment as necessary
Set of lifting straps of correct length and adequate SWL
The PLATINUM 6 tanks have been designed for 800mm invert.
Excavate to the PLATINUM 6 tank’s dimensions allowing a minimum clearance of 200mm between the tank and the excavation sides. Excavate to the appropriate depth for the installation i.e. : invert level of incoming drain plus depth of sump to invert of inlet pipe connection plus 200mm minimum concrete thickness (actual thickness to suit ground conditions).
Lay and level the concrete base for the tank to a minimum of 200mm thickness.
Lift the tank into position using slings attached to the two in-built lifting straps, one on each end of the tank, taking care not to damage any external flanges or pipework. Ensure correct orientations of the inlet and outlet pipework. Check that the tank is level in all directions. Commence back-filling with concrete in 500mm lifts, and at the same time, fill each tank compartment with water ensuring that the progressive concrete and water levels are approximately equal. The concrete must be evenly distributed around the sump, ensuring spigot connections are not covered at this stage.
NEVER WHOLLY FILL THE SUMP WITH WATER BEFORE SURROUNDING IT WITH CONCRETE
NEVER WHOLLY SURROUND THE SUMP WITH CONCRETE BEFORE FILLING IT WITH WATER
NOTE: DO NOT USE VIBRATING POKERS TO COMPACT THE CONCRETE
Make all interconnecting pipework connections, ensuring a minimum pipe gradient of 1:70.
Venting positions have been provided and are clearly marked on the units. A low level vent should be provided at the inlet and high level from the vent position marked on the access turret. This is important to create a through flow of air throughout the unit.
Provide and lay a 100mm uPVC duct from the PLATINUM 6 unit to the power supply. The connection is clearly marked on the side of unit.
Continue placing the concrete in 500mm lifts, terminating 100mm below the underside of the top flange. Allow an initial set of concrete between lifts and wait at least 24 hours for the concrete to harden. Where a high water table exists continue de-watering for 24 hours.
Back-fill around the unit with selected non-angular excavated material.
HIGH WATER TABLE/OR HEAVY WET GROUND
Whether the water table is high or the ground is non free-draining heavy clay, increase the thickness of concrete to suit site conditions minimum 250mm. Provide de-watering to keep excavations clear of water by providing 250mm shingle sub-base prior to laying the concrete base, provide a polythene 1200 gauge sheet between the shingle and concrete, de-watering can be carried out through a 200mm uPVC pipe placed into the shingle. This pipe can remain in position to continue de-watering until the concrete has set.
In order that you achieve a safe and cost effective installation, it is not possible to state a specific installation configuration that would suit all sites. The selection of current protection devices must remain the responsibility of the installer.
It is imperative that the electrical installation of this equipment is entrusted to a competent qualified electrician.
Ensure ANY packaging is removed from around the compressor/s prior to electrical connection/running.
When installing the electrical supply to the PLATINUM 6 unit, the following points should be considered:
1. The supply to the PLATINUM 6 unit should be by means of a dedicated
circuit with isolation and protection devices consistent with the requirements for fixed equipment and in accordance with the latest regulations of the Institute of Electrical Engineers.
2. The supply to the PLATINUM 6 unit should be independent of all
protection devices other than the supply authority’s fuse and that provided specifically for the PLATINUM 6 power supply. In particular, earth leakage devices provided for normal domestic protection must not form part of the supply circuit to the PLATINUM 6 unit.
The power supply cable should be passed through a gland in the side of the turret and connected, via a junction box, to the compressor housed within the unit, any terminal shrouds removed during the connection of cable cores must be replaced afterwards. A separate duct/conduit to be provided for the electrical supply. (Ducting/Junction boxes are not part of Anua supply).
Due consideration of location must be made:
2. Electrical and other services
3. Surface water
4. Audio and visual impact
5. Public access
6. Environmental impact
REMEMBER – ELECTRICITY CAN KILL
IF IN DOUBT = DON’T
The PLATINUM 6 process
The PLATINUM 6 is a new generation of Packaged Sewage Treatment plant developed to treat domestic and other biodegradable sewage waste in a simple and compact system comprising of three treatment zones within the design.
The submerged aerated media process used in the PLATINUM 6 is a development of the traditional trickling filter process and provides a more effective means of reducing ammoniacal nitrogen from the sewage.
Raw sewage flowing to the PLATINUM 6 is received in the primary settlement zone. Here, gross solids (sludges and other social debris) settle to the bottom of the tank where they remain until the tank requires desludging. The remaining effluent (supernatant liquor) is displaced from the primary settlement tank and then flows into the submerged media zones which are split into two compartments.
Flow circulation in the submerged filter zone is generated by the effect of the air diffuser arrangement. This causes settled sewage entering the filter zone to be drawn through the media, supernatant liquor passes through the media. As it does so, it is purified by the micro-organisms growing on the surface of the media. Growth of these micro-organisms results in an excess which is shed as solid particles known as humus solids. These are eventually washed down through the media to the final settlement zone (humus chamber).
When settled sewage enters the PLATINUM 6 it displaces an equal volume of treated liquor into the humus chamber; here the humus solids settle out and form a sludge on the bottom of the tank. This must be removed periodically as detailed in the Maintenance Schedule, section 6 of this manual.
The liquid displaced from the humus tank has been fully treated as described, and is known as final effluent, it is suitable for discharge to a watercourse or soakaway as defined in the Consent to Discharge.
PLANT START UP
All electrical work should be carried out by a competent qualified electrician.
If any equipment appears not to be operating correctly, refer to Fault Finding, section 8 of this manual.
1. Fill the plant with clean water until there is a discharge from the outlet.
2. Check the operation of the Residual Current Circuit Breaker.
3. Check the running current of the compressor is below the full load current rating
4. Check that water flows freely into and out of the plant.
5. Fit the manhole cover and lock if necessary.
PLANT SHUT DOWN
The PLATINUM 6 is now in an operational state. However, the treatment process relies on the growth of micro-organisms on the filter media. The time taken for these naturally occurring organisms to develop is dependent on temperature and may take up to six weeks in winter. Until the biomass is fully developed, the treatment process will be incomplete. During this time do not allow any strong cleaning agents or bleaches to enter the system.
Temporary absence of flow to the plant will not be detrimental, however, if the flow of sewage to the plant will be interrupted for more than four months, the following procedure should be completed.
1. Desludge all the compartments in accordance with the instruction in the
Maintenance, section 6, of this manual.
2. Refill the plant with clean water.
3. Fit the tank covers.
4. Stop the compressors.
END USER RESPONSIBILITY
The end-user of the sewage treatment plant is entirely responsible for the operation of the plant and for ensuring that the quality of the effluent does not breach the Discharge Consent Standards.
You are reminded that the existence of a Service Agreement does not transfer responsibility for general maintenance which must be conducted in accordance with the accompanying instructions.
Soakaway, drains and the emptying of primary tanks remain the responsibility of the client.
If the plant appears not to be operating correctly, refer to the Fault Finding, section 8 of this manual.
Should the following maintenance not be carried out, gross septic conditions and foul odours may occur within the unit. This would require considerable remedial work involving desludging and digging out of the media. Anua will not accept responsibility for these costs other than those expressed within our warranty.
DAILY Check the operation of the compressor. It should be possible to hear the compressor operating by standing close to the unit.
MONTHLY Check the operation of the compressor (bubbles rising in the media beds).
Remove and clean (if required) compressor air inlet filter.
Check the biomass growth on the filter media. The biomass should be
a light brown colour, not white or grey. The odour in the plant should be ‘earthy’. There should not be a noticeable ‘rotten eggs’ smell.
Check the final effluent. If this is cloudy or contains many suspended
particles, then the humus tank is likely to require desludging.
9-12 MONTHLY Desludge the primary and humus tanks. This is most conveniently
achieved using a conventional suction tanker. Please consult your local yellow Pages/Thomson Directory for contractors offering this service.
Remove the cover from the humus tank compartments. Carefully lower the suction hose into the compartment.
After desludging each compartment, it is essential that the unit is filled up with water. This can be done by using a hosepipe or by running several taps in the household.
Repeat the Plant Start-Up Procedures, section 5 of this manual
DO’S AND DON’TS
Tell your guests/visitors/staff that you have a specialist sewage treatment plant and tell them how they can avoid harming it.
Read the label and use the manufacturers’ recommended doses for all household cleaning products.
Use cleaning products little and often so the plant isn’t overloaded.
Spread your clothes washing throughout the week.
Stick to the same washing, dishwasher powders and other cleaning products – the bacteria in the plant will work more efficiently with products they are used to.
Use liquid cleaners for clothes washing and for dishwashers.
Spring clean and use large amounts of cleaners and chemicals in one day.
Have a ‘washing day’ – spread your washing throughout the week.
Use household bleach and other strong chemicals indiscriminately.
Keep changing your brands of household cleaners and washing powders.
Tip bottles of medicine, mouth wash etc down the toilet.
Put sanitary towels, tampon, disposable nappies, baby wipes, cotton wool, incontinence pads etc down the toilet.
Over flush the toilet unnecessarily – use a water-saving flush if it’s fitted.
Pour fat or grease from cooking down the sink or drains.
Change the oil in your chip pan and pour it down the sink or drains.
Use your waste disposal unit like a rubbish bin – use it sparingly.
Pour garden chemicals or car engine oil down the drains.
How will affect my daily life?
What cleaning materials and detergents can I use?
With a sewage treatment plant based on a biological process it is important to ensure that you use cleaning products which do not harm the bacteria used to degrade the sewage. It is also important to ensure that the final effluent discharged into local water meets the Environment Agency consent standards and has the minimum impact on the environment generally.
Your choice and use of household cleaning products can significantly affect the efficiency of your plant. This section will explain in simple terms how such products affect both the plant and the environment generally so you can make an informed choice about what products you should use.
‘Green’ or ‘environmentally friendly’ claims cry out to you from the packs of washing products on supermarket shelves. But are the products themselves really kinder to the environment or simply making ‘green’ claims because they are packaged in recycled boxes, refills or in compact form?
It seems that no detergent can be truly ‘environmentally friendly’ but that some can be said to be ‘less environmentally damaging’ because their polluting effects are kept to a minimum. The aim, as this chapter will explain, is to use detergents with the lowest possible toxicity, which can be biologically broken down as quickly as possible.
This is the process by which organic chemicals are broken down into simpler chemical units by the natural action of living micro-organism. It takes place in two stages –
Primary biodegradation when the main characteristic of a substance has disappeared such as when a detergent has lost its washing action – and Ultimate or Complete biodegradation. In waste water and sewage it is important that primary biodegradation of detergents takes place quickly to lessen any undesirable effects on the environment. Once your washing machine has emptied its waste water down the drain, the detergent must reach primary biodegradation within 19 days in order to meet existing regulations. However, it is much better if degradation is reached earlier as it will speed up the waste water treatment process and minimise the effects of the discharged waste water on the environment.
These are the basic cleaning agents in laundry products, which reduce the surface tension between the water and the fabric so that the water can penetrate it to remove the dirt. Most laundry detergents use petroleum based synthetic surfactants, which, although they conform to the legal standard for primary biodegradation, can still have a negative influence on the environment. High concentrations of surfactants can affect animal and plant life and when they were first introduced in the 1950’s caused thick foam to overtake the country’s rivers. Although a different chemical which is more easily biodegraded is now used, vegetables or soap based surfactants, such as those used in Ecover products, reach primary biodegradation much earlier and have less long-term impact on the environment.
Another controversial ingredient, which can cause environmental damage is phosphate which is commonly used as a water softener, to break down dirt and keep it off the fabrics as well as to make the washing powder ‘flow freely’. An overabundance of phosphorous in rivers and streams can lead to eutrophication – a process where algae takes over and harms animals and plants. Although there are other sources of phosphate in Britain’s water – part in the eutrophication problem. Fortunately, many detergent manufacturers are now producing phosphate-free laundry products.
Most laundry detergents contain sodium perborate or bleach, which releases boron as it breaks down. Boron has a bactericidal effect, which in excessive quantities could damage your treatment plant so it is wise to keep bleach levels to a minimum.
Environmental groups claim that only one out of every four household washes contain white clothing which needs bleach. As bleach is included as a standard ingredient in many laundry detergents this means we are often washing lightly soiled coloured clothes with added bleach, which is totally unnecessary. Also sodium perborate, the standard bleach does not work until the temperature reaches 60oC so special bleach activators of TAED’s are added to some powders. If powders, which do not include these bleach activators are used for low temperature washes the bleach is not activated and can be released into the waste water totally unused. In this way wasted or even unused bleach is regularly flushed into your treatment plant and eventually the residue into the environment.
Ecover laundry products do not contain bleach. Instead they recommend and market a separate laundry bleach which can be added to the washing powder for white or heavily soiled coloured washes only when it is needed. They also use percarbonate as an alternative to sodium perobate. This is activated at low temperatures (40oC) without the aid of bleach activators and they claim it has a minimal effect on the environment .
Alternatively, for lightly soiled or coloured washes, you could use one of the newer laundry products specifically designed for colours which do not contain either bleach or optical brighteners.
Optical brighteners or fluorescers
These are included in many products to give the ‘whiter than white’ look. They create an optical effect and are purely cosmetic – they only give the appearance of whiteness but do not actually make the clothes any cleaner. Unfortunately they are very difficult to break down in treatment plants, degrade slowly in rivers and lakes and may even cause allergic skin reactions in some people. Ecover products do not use optical brighteners and many of the newer ‘colour’ detergents do not include them.
Many washing products which claim to be ‘green’ appear to make these claims purely because they are in recycled packaging or because newer ‘compact’ powders and ‘concentrated’ liquids use less packaging or are sold in refill packs. Whilst a reduction in packaging is obviously good for the environment generally, it is important to be aware that this does not necessarily mean the product itself is ‘green’. The most important thing is to read the label and product information on the package, identify the ingredients and then choose the products most suited to both your needs and the smooth running of your sewage treatment equipment. Following the recommendations on dosage is also particularly important.
To verify motor overload setting, refer to the Specification, section 8 of this manual. All electrical work should be carried out by a competent qualified electrician.
