Aug 01, 2020 Due to its high adaptability to influent quality, flexible operation mode and stable process performance, biological wastewater treatment is the most frequently employed technology in wastewater treatment plants worldwide Mahmoud et al., 2013.However, sewage sludge mainly composed of excessive bio-sludge is an inevitable by-product of biological
Bottom sludge collectors are used for removal of any settled sludge or grit that may accumulate. Sludge thickening occurs in the floating sludge blanket, which is normally 8 inches to 24 inches thick. The buoyant sludge and air bubble mixture forces the surface of the blanket above the water level, allowing water to drain from the sludge particles.
