Decentralized Wastewater Treatment Systems (DEWATS) for the Ha Phong Slaughterhouse

Another area chosen for the application of decentralized wastewater treatment system (DEWATS) is the Ha Phong Slaughterhouse in Ha Long City, Viet Nam. As a fairly large slaughterhouse in the city, the untreated wastewater that it was producing prior to the project was polluting the surrounding area. The health and environmental risks were high as slaughterhouse wastewater is more potent than domestic wastewater. An effective treatment system was therefore needed, especially since Ha Long City sits alongside the world-famous Ha Long Bay tourism area, which is too precious to become polluted.

This module of DEWATS used by Bremen Overseas Research and Development Association (BORDA)-Viet Nam consists of the following sections, in order of wastewater flow: two biogas digesters, settling unit, anaerobic baffled reactor (ABR), anaerobic filter (AF), horizontal gravel filter (HGF), polishing pond, and discharge pipe. The system was designed to treat 40 cubic meters per day (m3/day) of wastewater.
