BIOCLERE® wastewater treatment plant
Descriptionback to top
BIOCLERE® is a biological wastewater treatment plant which is safe to operate and reliable. The system copes with small to medium amounts of wastewater, from single family homes to sites with a population of up to 2000 people.
The treatment process comprises a septic tank for mechanical separation and a BIOCLERE® biofilter unit for biological treatment process. As wastewater trickles through the biological filter media, organic material is transformed into biomass, which grows on the surface of the HUFO® filtermedia. Treated effluent is separated from the biomass in the clarifier and can be discharged to soil or surface waters. Supplementary stages can be added to provide fully nitrified final effluent or phosphate removal.

Featuresback to top
Water distributor has no moving parts
Correctly installed BIOCLERE® will guarantee years of trouble-free performance. BIOCLERE® is sealed and insulated to minimize the impact of seasonal temperature variations on the treatment process. BIOCLERE® minimizes the impact of daily flow variations and short absence of sewage flow. The filter irrigation rate is constant day and night. During periods of low flow, the equipment utilises wastewater stored in the pump well. Temporary variations in load will not affect the performance of the filter.

The water stored in the pump well acts as a source of nutrients for the micro-organisms in the unit if the wastewater flow to the purifier is stopped for several days..
