Brief Description

Description :

This technology removes dissolved organics from wastewater without generation of sludge and with low input electrical energy. In this technology, both biological and catalytic systems are integrated to oxidize organics present in wastewater at ambient environmental conditions. The biological oxidation of organics is performed by immobilized bacteria in fuctionalised mesoporous activated carbon and catalytic oxidation is performed actively by electron rich activated carbon matrix. CAACO technology has been implemented for the treatment of wastewater discharged from domestic and industrial sectors such as leather, textile, chemical, pharmaceutical, food etc.
