Long\u2010term experiments were conducted by varying hydraulic retention time from 6 to 8 hours and solids retention time from 20 to 50 days, respectively. The performance was assessed by monitoring key wastewater parameters, including chemical oxygen demand (COD), nitrogen, and phosphorus concentration in individual anoxic, anaerobic, aerobic, and membrane separation zones. Results showed that the tested system can consistently achieve COD, nitrogen, and phosphorus removal efficiencies at 80 to 98%, 70 to 93%, and 89 to 98%, respectively. Effluent COD remained low as a result of efficient solid retention, even though there was great variation in influent quality. However, total nitrogen increased proportionally with influent concentration. At a 50\u2010day solids retention time, higher COD and nitrogen oxides specific utilization rates in the anoxic zone resulted in a high production of nitrogen oxides in the subsequent aerobic zone.<\/jats:p>","DOI":"10.2175\/106143006x105274","type":"journal-article","created":{"date-parts":[[2006,4,22]],"date-time":"2006-04-22T16:37:44Z","timestamp":1145723864000},"page":"538-545","source":"Crossref","is-referenced-by-count":10,"title":["Performance of a Submerged Membrane Bioreactor System for Biological Nutrient Removal"],"prefix":"10.1002","volume":"78","author":[{"given":"Javier","family":"Mouthon\u2010Bello","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hondge","family":"Zhou","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2006,5]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"crossref","first-page":"281","DOI":"10.2166\/wst.2002.0606","article-title":"Enhanced Biological Phosphorus Removal in Membrane Bioreactors.","volume":"46","author":"Adam C.","year":"2002","journal-title":"Water Sci.
