Regulations & Your Responsibilities A package sewage treatment plant is an essential component of the home or workplace. It provides safe and hygienic wastewater treatment and disposal to make sure your family and colleagues have a pleasant place to live and work and that the local community and environment is protected.
Introduction This Installation, Operation and Maintenance (O&M) manual includes descriptive literature, specifications and drawings relating to the principal mechanical and electrical equipment incorporated in the unit. It is the responsibility of the installer and operator to read and fully understand these instructions before installing, commissioning or operating the plant.
Health and Safety (Important - Please Read This Before Staring Any Work on the Plant.) Safety, Health and Welfare at Work Act 2005. Section 16.1(a) of this Act requires manufacturers to advise their customers on the safety and the handling precautions to be observed when installing, operating, maintaining and servicing their products. The user’s attention is therefore drawn to the following: 1. The appropriate sections of this manual must be read before working on the equipment. 2.
SAFETY Sewage gases are potentially hazardous. DO NOT enter the unit or any sump. Before carrying out any maintenance work, the equipment must be electrically isolated by switching off the power to the plant. DO NOT leave manways open for any longer than is necessary. Temporary barriers and warning signs should be erected around any open covers or manways as appropriate.
Process and Plant Description The EPS Bison ASP treatment plant has an inner central chamber and an outer settlement tank. The plant treats sewage using the extended aeration principle in the central bio-zone chamber. A simple course bubble diffuser, housed in a draft tube, introduces the air that provides the oxygen to the bacteria that then treats the sewage. The bio-zone retains the mixture of water, sewage and air until a level of treatment has been achieved.

Delivery OFFLOADING The purchaser is responsible for offloading the tank and any accessories using the following method: • using straps through the eyebolts (Any chains or steel ropes used in rigging must not be in contact with the tank) Do not lift the tank if it contains any water. Maintain control over the tank when lifting by use of guide ropes. Do not allow the tank to impact against other objects.
Installation INTRODUCTION Installation procedures must be in accordance with the Safety, Health And Welfare at Work Act 2005, and other relevant legislation. Your procedures must also align with good building practice. This procedure is issued as a guide only. EPS Bison accept no liability for incorrectly installed units. If the customer has any concerns then a suitably qualified groundworker who has full access to all site conditions should be consulted.
INSTALLATION HINTS • Installation of the Bison ASP should be carried out as per the Bison ASP Installation manual. • Use concrete encasement where applicable. • Use granular self-compacting material as backfill. Avoid sharp / large stones in backfill. • Ensure base is adequately compacted stone / sand to avoid subsidence. • Ensure the system is levelled accurately to enable continued operation of the system.
Declaration of Site Readiness Bison ASP Gravity Discharge Client Address Date Tank No A/C Ref Phone No Warranty Email To avoid abortive visits, standing time and or return visits, and consequential costs, we outline below a list of requirements, which must be met before we attend site for commissioning.

De-Sludging Bacteria and other micro-organisms present in the wastewater utilise the organic material as a food source, converting it into a non-soluble mass. This non-soluble mass or floc is compromised of living micro-organisms, sewage particles, as well as inert (nonbiodegradable) material. As the process matures, the numbers of micro-organisms increase until there is an adequate biomass to metabolise or digest all of the soluble organic material in the incoming sewage.
PROCEDURE FOR DE-SLUDGING 1. Remove 6” cover from de-sludging access point. 2. Carefully lower a 3” tanker hose down through the de-sludging access point until it rests on the bottom of the outer tank (clarifier) or until the hose meets light resistance. Do not force the hose down further as this may damage the internal workings of the unit. Depending on the invert level between 2.35m – 3.3m of hose is required to reach the bottom of the tank from ground level. 3.
Maintenance Schedule WEEKLY INSPECTIONS • C heck the final effluent discharging from the unit at the sample point. If it is cloudy or contains suspended particles contact your maintenance provider. 6 MONTHLY CHECK (OR AS STATED OTHERWISE) We recommend that the unit is checked by an approved service technician at the first 6 monthly check. As for weekly, plus • Any signs that the compressor is overheating. • Air Leaks and excessive heat in the air hose, and the fittings are secure.

Appendix C: Settle Ability Test SETTLEMENT TEST TROUBLE SHOOTING GUIDE Colour grey: There may be too much laundry effluent going into the plant. Ask the residents to check they are not putting in too much detergent. Check that the Laundry use is not all on one day of the week and it is spread out. Try to limit the use to 1 to 2 clothes washings per day. Another possibility is that surface water from the roof etc. is entering the plant. White deposits in the activated sludge.
Appendix D: Fault Finding Symptom Strong odour Cause Action Excess chemicals in the plant See appendix E Excessive laundry use See appendix E Carry out a settlement test See appendix C Drains inadequately venting Check that a high level vent is fitted to the house and is working correctly Nothing obvious can be found Carryout 12 month service and correct any faults found Lack of aeration Check air pump Switched off at the mains isolator Switch on Power failure Check the supply board for a
Appendix E: Household Practices: Do’s & Dont’s INTRODUCTION When we take a bath, put the washing machine on or flush the toilet few of us stop to consider what happens to the waste water and sewage. It simply goes down the drain or waste pipe and is no longer our concern. But if your drains lead to a packaged treatment plant, particularly one using a biological treatment system, then it’s worth paying some attention to what happens next.
SO HOW SHOULD I USE CLEANING PRODUCTS? LAUNDRY DETERGENTS Firstly you need to find out the level of hardness of your local water (see section on water softeners). Once you know how hard or soft your water is you can read the label on your laundry detergent and decide how much to use. The aim is to minimise the amount of detergent you use to limit its impact on the treatment plant whilst ensuring you get the best results from your wash.
WATER SOFTENERS To reduce the quantity of laundry detergents you use you need to find out how hard your water is. You should contact EPS for advise on this. The hardness of water is determined by the amount of calcium and other minerals it contains. Hard water is rich in calcium which reduces the effectiveness of soap and detergents. There is a scale of water hardness: 0 – 71.3ppm very soft, 71.3 – 142.5ppm soft, 142.5 – 213.8ppm medium hard, over 213.8ppm hard.
Appendix F: Alarm The Bison ASP alarm is contained in the control box of the Bison ASP. The control box sits in the blower housing of the unit. It is an audible alarm that will sound if: • There is a high liquid level in the Bison tank. • If there is a drop in air pressure coming from the air blower. A. Power to Pump & Blower RCBO B.
