TL;DR: The integration of bioflocculation of grey water in decentralized sanitation concepts may increase the overall production of methane by 73%, based on the biogas produced by black water only.

TL;DR: The experimental results indicated that anaerobic and aerobic residence times in SBR systems significantly affected the system's performance and higher concentrations did not improve color removal but decreased the COD removal performance of the system.

TL;DR: In this paper, it was shown that the most important factor is the rate of biological denitrification, while other factors like nitrogen gas solubility and oxygen concentration in settler influent only play a minor role.

TL;DR: During the 91 days of experiment on the treating secondary effluent of Guang-Rao wastewater treatment plant, it was found that the fiber-bundle carrier could collect the heterobacteria and nitrifying bacteria gradually, and thus improved the COD removal efficiency and nitrification performance step by step.
