Sludge reactor

Webb9 sep. 2024 · In fact, the production of sludge is an important differential in the choice of the treatment system. While purely aerobic systems such as activated sludge or high-rate biological filters can produce 0.6–0.8 kgSS/kgBOD applied, sludge production in an upflow anaerobic sludge blanket (UASB) reactor is only about 0.2 kgSS/kgCOD applied. WebbHere, waste-activated sludge was used without super-electronization, but the excess sludge was fed by hydrodynamic disintegration, during which a cavitation effect occurred. As a result of this research, a 37% increase in the amount of biogas production was obtained, while methane was up by 152% per VS unit at an optimal energy density equal …
