Chapter six: Aerobic versus anaerobic wastewater treatment

In fact, the treatment of ,wastewater, might be a net energy producer (Switzenbaum 1984). Originally, anaerobic treatment was the preferred process for domestic ,wastewater, management. Imhoff modified the septic tank for ,wastewater, treatment in Germany, and by 1933 the Imhoff tank was used by over 240 towns in Germany.

NF experiments with MF-prefiltered secondary effluentsThe experiments with MF-prefiltered secondary effluents (TSS = 5.1 mg/l, COD = 55.6 mg/l) lasted from few days up to 12 days. During 12 days experiment the rejection of the organic matter and brine were steady along the experiment and were about 70% and 60%, respectively.
