Abstract
This paper presents an alternative method for nitrogen removal using modified membrane reactor. A novel Anammox submerged membrane electro-bioreactor (Anammox-SMEBR) was developed to enhance nitrogen removal from municipal wastewater. At lab scale a comparison between continuous flow MBE and Anammox-SMEBR reactors was conducted. The novel reactor removed nitrate and ammonia by over 95% and 97%, respectively. The removal was due to subsequent application of aerobic and anoxic conditions in the same reactor. On other hand, MBR was able to remove ammonia by 60 to 76%, while nitrates were produced. Simultaneously, COD and phosphorous removals in MBR were also lower than in Anammox-SMEBR.
