Sludge generation calculation
WebbThe physico – chemical characteristics of the sludge bed play a key role in deciding the biomethanation capacity of the reactor. The amount of daily deposition of sludge depends on the characteristics of raw waste water. The design of the reactor is accomplished as described below, 3.1.1 Total Sludge Production Webb6 apr. 2024 · A self-powered electrocoagulation system with a single-chamber aluminum–air fuel cell was employed for phosphate removal in this study. Electricity production and aluminum hydroxides in solution were also investigated. When the NaCl concentration increased from 2 mmol/L to 10 mmol/L, the phosphate removal increased …
