Community Domestic Wastewater Treatment by UCT-HMBR Process

Abstract:

In order to treat community domestic wastewater, the UCT (the University of Cape Town) process coupled with the Hybrid Membrane Bioreactor (HMBR) was selected to constitute a combination process UCT-HMBR. This hybrid reactor was characterized by high total biomass and low membrane fouling. After 42 days’ running, a significant biofilm was formed in the reactor. Data collected during 60-day stable running period showed that the average COD_Cr and ammonia removal efficiency are 95.7% and 97.7%, respectively. When the nitrate liquid recycle ratio is 300% the total phosphorus (TP) removal reaches the peak and TP removal efficiency is 83.2%. At the same time, the effluent total nitrogen is less than 15mg/L. The effluent of the UCT-HMBR can meet the national water reuse standard.
