How the Klargester BioFicient works

The Klargester BioFicient 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. The Klargester BioFicient 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.

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.

*Some units have more than one access shaft - diameter of largest shown
The Klargester BioFicient's individual chambers have large dedicated manholes to allow quick and easy maintenance access. Servicing is also simplified as the Klargester BioFicient's flow control makes it unnecessary to empty the biozones, as is the case with other designs of treatment plant.

As a result, the biozones immediately resume operation following servicing, whilst the influent level is restored. As a result there is no loss of plant performance during periodic maintenance.

Specialist Advice

Delivering high quality effluent requires careful evaluation of the various parameters affecting each scheme. Relatively minor changes may result in the loss of one or more of the required effluent qualities.

Kingspan's team of technical specialists assess each site’s demands and application and tailor a technical specification to meet the consent requirements.

Plant sizing is not only calculated on current demand but also gauged on potential future loading in order to meet the latest legislative criteria.
