Hubert Enviro Care Systems (HECS) P Ltd conducted a "Technical Seminar on Membrane Bio-Reactor (MBR) based Sewage and Effluent Treatment Plants in Hospitals" jointly with PWD.(Medical Division) and Christian Medical College (CMC), Vellore on 8th July 2022.During the seminar, Mr. K. Ayeratharasu Rajasekharan, Superintending Engineer, PWD Medical Wing Chennai, emphasized, "It is high time to promote the sustainable development in need for reclamation of Sewage and Effluent Wastewater from Hospitals aiming at Zero Liquid Discharge (ZLD), to reduce the consumption of fresh water and also to comply with the Pollution Control Board norms".
