WebPrimary treatment removes material that will either float or readily settle out by gravity. It includes the physical processes of screening, comminution, grit removal, and sedimentation. Screens are made of long, closely spaced, narrow metal bars. They block floating debris such as wood, rags, and other bulky objects that could clog pipes or pumps. In modern … WebThe heart of the A-B process was the initial high-rate activated sludge (HRAS) process, which is a biologically enhanced primary treatment process that can maximize carbon redirection and harvesting from wastewater. The popularity of this technology (and other two stage processes) began to decline in the 1990s as effluent requirements for ... solitary eating
