The Scientific Principle


There are three treatment zones within the single BioSure tank structure.  The first zone is a primary settlement chamber where solids and floating material are retained.  The liquids pass through to the second chamber, which is a biozone.


Central to the operation of the BioSure sewage treatment plant is the biozone.  Within the biozone aerobic micro-organisms develop through the use of fine bubble aeration and floating plastic media.  This biozone process provides an extremely robust means of treating sewage, especially for reducing Ammoniacal Nitrogeon.


The third chamber is a final settlement zone where fine solids are separated and returned automatically to the first chamber using a recirculation airlift.  The treated liquid is then suitable for discharge direct to a ditch or stream.


The only electrical component for the BioSure is a small air compressor.



BWSelecting the right BioSure


BioSure sewage treatment plants are available in population equivalents of (PE) 6 – 55.  When sizing a new sewage treatment plant the British Water Flows & Loads Code of Practice – 3 should be used.  This Code of Practice provides the information required to ensure the correct size of treatment plant is installed.
