BIO-BLOK®

As a result of many years of research and development, a structured filter media has been developed. BIO-BLOK® has proved extremely efficient in biological treatment of domestic sewage, industrial wastewater and process water within the aquaculture field.

Environmentally friendly, the media is made from polyethylene and consists of net tubes, which are welded together to form a square block. The unique surface structure of the many net tubes provides a large, accessible surface area for enhanced biological growth on the filter media.

The surface acts as a substrate for specialised bacterial strains, which are able to treat and degrade a wide range of wastewater qualities. The treatment capacity of a biological filter depends on the quantity of bacteria that the filter can sustain. The larger a specific surface area is, the larger the bacterial population. Future construction, refurbishment or upgrading of biological wastewater treatment plants is merely a matter of creating optimal ‘living conditions’ for the bacteria. BIO-BLOK® has excellent properties in this respect, and the result is an increase in treatment capacity.
