Abstract |
|
Conventional rotating biological contactor was provided with radially divergent rotating arms in place of discs. Arms were filled with plastic mesh to increase the residing area of microorganisms. The three compartments in the reactor consisted rotating arms assembly while two baffles that separated the compartments were filled up with plastic scrubbers to provide an extra area for biofilm growth. Domestic wastewater was used to test the efficiency of lab scale model. Tests for BOD, COD and TS were carried out for a detention time of 24 Hours and rotational speeds of 4 rpm, 7 rpm and 10 rpm. Maximum efficiency was observed at rotational speed of 4 rpm. Average percentage removal of BOD, COD and TS was observed as 81.95%, 82% and 79% respectively. |
