The treatment system patented by Clewer Oy is an innovative method of biological processing where the water is returned to the environment purified, while the organic and inorganic residues are removed and processed separately under the form of muds.
The biological treatment RBBR (Rotating Bed Biofilm Reactor) is based on the principle of adhesive biomass, where the growth of bacteria happens within the internal chambers of a protected support system called carrier.
Carriers are continuously rotating inside a cylindrical bioreactor thanks to blown air that gives the rotatory motion to the water as well as providing the necessary oxygen sufficient to promote the aerobic biological reactions.
The bacterial colonies (biofilm) feed themselves and process the organic and inorganic components of the wastewater while growing undisturbed within the carriers. The exhausted bacteria (in the form of mud) are continuously removed from the bioreactor through an hydraulic overflow process.
The layout of the RBBR process allows to obtain maximum performance for the biological purification obtaining extremely high returns and maximum breakdown of Carbon, Nitrogen and Phosphorus based pollutants.
