Biological nutrient removal (BNR) is generally integrated in municipal wastewater treatment plants to alleviate the impact of treated effluent on receiving watersheds. This paper studies the performance of BNR in a membrane bioreactor system consisting of anaerobic, anoxic, micro-aerobic and aerobic compartments treating a synthetic wastewater containing low organic matters. The membrane bioreactor system designed an anti-stream, stepwise return flow scheme to produce ideal conditions for the occurrence of simultaneous nitrification and denitification and denitrifying phosphorus removal processes. The proposed membrane reactor system has established higher biomass concentrations and ideal environments for biological nutrient removal processes, which results in high nutrient removal efficiencies treating low organic wastewaters. Four compartment configurations in the reactor system minimized the impact of oxidized nitrogen species in return flow on phosphorus release in the anaerobic tank and the anti-stream, stepwise return flow scheme encouraged the utilization of nitrate as the electronic acceptor in phosphorus uptake in the micro-aerobic tank. Denitrifying phosphorus removal and simultaneous nitrification and denitrification processes are the main mechanisms responsible for efficient nutrient removal. High phosphorus release activities and high phosphate concentration in the anaerobic tank make it is potentially feasible to recover phosphorus resource from wastewater.

The performance of a biological system was evaluated for copper removal with and without the addition of an adsorbent to the aeration compartment. Three different reactors were employed in this study. The first reactor consist of biomass alone and was used as a control reactor (CR). The second reactor consist of biomass and microwave incinerated rice husk ash (MIRHA) whereas the third reactor consist of biomass and hybrid adsorbent (HA), which is a mixture of MIRHA and groundwater treatment plant sludge (GWTPS). The reactors were operated at solid retention time (SRT) of 30 days and hydraulic retention time (HRT) of 19.8 hours. The experiment was conducted in 8 different phases consisting of various copper concentrations coming from the influent source. The first and second phase were acclimation period during which copper was not added to the influent wastewater. From the third to the eight phase, copper was fed to the reactors at different concentrations. Reactor performance was monitored every two days. Results show that copper toxicity was significant for the control reactor from phase from phase 5 to phase 8 with effluent concentration between 0.34 – 2.62 mg/L. Copper removal was significant for both MIRHA and HA reactor. Effluent copper concentration in the MIRHA reactor was 2.04 mg/L and 1.09 mg/L for HA reactor at phase 8 (copper concentration 15 mg/L). Addition of the adsorbents (MIRHA and HA) enhanced the biomass tolerance towards copper toxicity at high concentration and improved copper removal efficiency. This study, therefore demonstrates that low cost non-conventional adsorbents could be utilized as support materials to enhance biomass tolerance towards heavy metal toxicity.
