KLARGESTER Bio Disc
The Klargester compact sewerage treatment plants come in different variants to cater for the sewerage requirements of a single house with up to 6 full time occupants to systems that will cater for entire housing estates. The two primary Klargester systems are the Bio Disc and the Airflow system.
The Klargester systems are quiet, odour free and require little maintenance. Their other main benefits are that they require much less space than a traditional septic tank system and the final output is less deemed clean enough to go straight into a water course.
Shown right is the Klargester Bio Disc arrangement which creates a large surface area for the natural bacteria required to break down the effluent in the waste that comes into the system. This works in a similar way to many large scale odour free industrial systems used in the UK by the large water companies. The trick here is to create a large surface area for the bacteria to thrive on whilst keeping the physical size of the system to a minimum.

Process Design
Envirosafe sewage treatment plants employ a plug flow combination of aerobic and anoxic processes in a fluidised bed arrangement. This operates in conjunction with an advanced system of air diffusers and selected media to deliver optimum levels of purification.
This process takes place in three distinct stages:-
1. Primary Settlement
This is the initial stage of treatment and simply involves the retention of coarse solids present in raw sewage and wastewater for subsequent gradual breakdown. Envirosafe features two chambers to ensure efficient operation with a flow balancing facility.
2. Biological Treatment
Substantial BOD reduction takes place here, where the carbonaceous pollutants are removed by presenting the sewage to the micro-organisms in the presence of oxygen. The treatment is achieved by high efficiency air diffusers continually pumping oxygen through the biological media and fluidised effluent. Standard Envirosafe models utilise two aerobic treatment chambers for lower performance applications. Where higher effluent standards are required, the HEQ models employ a third anoxic zone.
3. Settlement
A natural by-product of biological treatment is humus sludge and this is separated for further treatment. The treated effluent is discharged via the outlet.
Total nitrogen consents can be achieved with HEQ models (contact talbotracer@aol.com for your application).
