Tanks & Treatment Plant - Performance

This section provides answers to many frequently asked questions.

How long before my treatment plant starts to work properly?

Every newly installed treatment plant can be used immediately but a time period is required for the biological process (that breaks down the sewage) to fully develop. This process can take up to 6-8 weeks (subject to unit model & ambient conditions).

Klargester offers a Post Installation Inspection service to ensure correct operation and for extra peace of mind.

Will it smell?

If normal installation & operation procedures are followed any Klargester Treatment Plant should not emit unpleasant odours.

In 2005, BioDisc gained certification to European Performance Standards, the Testing Engineer’s official report stating ‘There was no nuisance caused by noise or smell from the plant’.

Will it be noisy?

If normal installation & operation procedures are followed any Klargester Treatment Plant should not emit any unwanted noises.

In 2005, BioDisc gained certification to European Performance Standards, the Testing Engineer’s official report stating ‘There was no nuisance caused by noise or smell from the plant’.

What quality of water is produced?

With sewage treatment, water quality is defined by the level of three forms of pollutants that are present in the water exiting a treatment plant. The three pollutants are

• BOD – Biological Oxygen Demand (a measure of the biological pollutant load)
• SS – Suspended Solids (small particles of waste matter)
• Ammonia – (Ammonia is the chemical that creates urine odour)

The better a treatment plant’s performance, the lower level of these pollutants, expressed in milligrams per litre – The BA BioDisc for example has been certified to deliver (in normal domestic situations) an effluent quality of 15mg/l BOD, 25mg/l SS and 15mg/l ammonia, expressed as 15:25:15.

These are exceptional high levels of quality, falling well within the common standards demanded by the environment agencies. It is important to bear in mind that discharged water from any plant is not suitable for consumption or washing but a sample will have a high level of visual clarity.

What power is needed and how much will it cost to run?

All Klargester Treatment Plants require an electrical supply and are extremely economical to run, often costing less than a 60watt lightbulb per day.

In 2005, the BA BioDisc gained certification to European Performance Standards, the Testing Engineer’s official report stating a mean power consumption of 1.3kWh/d (roughly 10 – 14 pence per day, depending on supplier).
