Final Effluent

An anaerobic submerged membrane bioreactor was coupled with a novel hydrogen delivery system for hydrogenotrophic denitrification of municipal final effluent containing nitrate. The biological treatment unit and hydrogen delivery unit were proven successful in removing nitrate and delivering hydrogen, respectively. Complete hydrogen transfer resulted in reducing nitrate below detectable levels at a loading of 0.14 kg N m−3 d−1. The produced water met all drinking water guidelines except for color and organic carbon. However, the organic carbon was removed by 72% mostly by membrane rejection. To reduce the organic carbon and color of the effluent, post treatment of the produced water is required.

Final Effluent

a submerged membrane bioreactor was used to treat the effluent of a pharmaceutical wastewater treatment system, the treated water is rich in ammonia nitrogen and organic compounds (NH4-N, averaged in 78.1 mg/L; COD, averaged in 189.5 mg/L), the final effluent of membrane bioreactor was stably below 50 mg/L COD and 40 mg/L NH4-N respectively, the activity of nitrifying bacteria was inhibited by high concentrations of organic compounds and ammonia nitrogen, a rapid declination of filtration was probably resulted form high concentrations of organic compounds and biomass.

Produced water, the significant wastewater in association with oil and gas production in oilfield, is characterised by the presence of crude oil and also many inorganic substances. It is very difficult to treat this water to meet the reinjection water quality for low and ultra-low permeability reservoirs. In the present paper, the treatment of produced water from Daqing Oilfield was investigated using a submerged membrane bioreactor (SMBR). The SMBR was operated for about 6 months with constant permeate flux and hydraulic retention time HRT of 12 hours. The experimental results showed that the SMBR had a high retention of crude oil, total suspension substance (TSS), turbidity, ammonia nitrogen (NH4+-N), and medium grain size. In the permeate, the content of crude oil, NH4+-N and turbidity were respectively lower than 1 mg/L, 1mg/L, and 1 NTU, while the TSS content was below detection limits (2.5 mg/L) and medium grain size was undetectable. The pemeate could reach the grade A1 criteria specified in the Recommendation Standard and Analysis Method for the Clastic Rock Reservoir Injection Water Quality (SY/T 5329-94, China).

Coastal Zone Act Reauthorization Amendments (CZARA, Section 6217) necessitate the requirement that onsite wastewater disposal units located near impaired surface waters or groundwater to provide at least 50% nitrogen removal. Approximately 38% of Hawaii households use onsite systems including septic tanks and cesspools that cannot meet this requirement. Upgrades to aerobic treatment units (ATUs) are a possible compliance solution. In Hawaii, ATUs must meet National Sanitation Foundation Standard 40 (NSF40) Class I effluent criteria. Previously, a multi-chamber, flow-through, combined attached/suspended growth type ATU (OESIS-750) and presently, a sequencing batch type ATU (CBT 0.8KF-210) were evaluated for NSF40 compliance, nutrient removal capability (NSF245), and adaptability for water reuse (NSF350). Both units easily achieved the NSF40 Class I effluent criteria. While the OESIS-750 achieved only 19% nitrogen removal, the CBT unit achieved 81% nitrogen removal, meeting the NSF245 criteria and CZARA requirements for applications in critical wastewater disposal areas. In addition, the CBT consistently produced effluent with turbidity less than 2 NTU (NSF350) and UVT254 greater than 70%, facilitating the production of unrestricted-use recycled water.
