Care & Maintenance Tips

Care and Attention for Treatment Plants

Modern treatment plants of a quality make are designed to give many years service in ground contact and dealing with a harsh internal environment.     As with any product a little care and attention will help allow the plant to operate at optimum efficiency.

Treatment plants work on a build up of a mix of bacteria that deal with the carbon and nitrogen contents of the waste products.      As regards what should and should not go into the system it relates simply to what will affect the overall health of the biomass population.    The following are a few tips gathered from our experience over the years:

Oil and fats should be avoided as they accumulate over the years coating the media on which the bacteria grow and limiting further growth.   In domestic situations much of this comes off plates and a quick wipe with kitchen paper before the dishwasher makes a huge difference. If fat does become a problem then an enzyme based dosing control can be added to the plant relatively cheaply. Commercial properties with kitchen facilities are strongly advised to follow this route.

Bleach and household cleaners. The biomass is relatively large and will tolerate reasonable quantities of chlorine releasing agents (bleach) but avoid excessive use.  We also suggest own brands as they are often weaker (and cheaper) and therefore less damaging. 

Unwanted medicines.    Do not dispose of unwanted antibiotics etc via the toilet.
This list can be by no means exhaustive but it relates to common sense. Used engine oil, paint, paint thinners, builders rubble, clothing and even an old barbecue are all products found so far in plants which will not in anyway facilitate the effective running of the plant. 

Any fibrous material should not be disposed of via the toilet, this includes nappies, sanitary items, baby wipes, hygiene & facial wipes etc as they do not rot down. They will be removed on the desludge but they should not be disposed of this way whether it be mains or off mains drainage.

In summary there are no special things to avoid but rather just the use of common sense.    It is a natural process designed to deal with human waste products and it is not a general disposal mechanism.  If it can pass through your body – it can pass through the plant!

A periodical check of the air blower housing (where fitted) is also worthwhile to ensure that ants, mice, bees etc have not set up home and restricted the airflow to the compressor. The housing should also be kept clear of plants and vegetation to maintain a good airflow.

All units need regular desludge and services to maintain a healthy biomass and it is generally a condition of Environmental Agency Consent that a service contract is entered into.    Differing sizes of plants require a different level of attention subject to their loading.   

A unit for a single domestic property will generally require one service and one desludge per year.  We are pleased to advise on the appropriate regime and then carry this out according to the manufacturer’s instructions

Please also always remember that you are legally responsible to ensure that the system does not cause pollution, health hazard or nuisance.
