Sewage Treatment Plant

The sewage treatment plant is designed to treat wastewater generated from the processing unit. The treatment plant will have two distinct sections namely Fluidized Bed Bioreactor Biological Treatment and Electro coagulation Treatment Plant. The Effluent treatment plant is designed to treat 2,000 m3 of Textile Dyeing effluent generated from the process house. The plant will be capable of operating at the flow rate of 100 m3/hr. The operating cycle of the plant shall be 20 hours.

Sewage Treatment Plant Characteristics

The Sewage Treatment Plant is designed based on the analysis of effluent analysis report of Combined Effluent provided by you.
