SMALL SEWAGE TREATMENT SYSTEM

Our Small Sewage Treatment System adopts conventional activated sludge process using a diaphragm pump which includes air into the aeration tank to reduce the BOD5 and suspended solid concentration. This process will enhance the growth of micro organisms which digest and convert the organic and bio-chemical substance in the sewage into simple and harmless residues.
