Description 1899-1904
Stringed Bed Suspended Bioreactor (SBSBR) is a fixed
film bioreactor activated with indigenous nitrifying bacterial consortia under
salinity regimes of 15 and 30 ppt for rapid nitrification in brackish water and
marine aquaculture systems respectively. Compared to domestic wastewater; total
ammonia nitrogen (TAN) is a limiting factor for nitrification
in most aquaculture treatment
systems.  Therefore, the nitrification by
SBSBRs was analyzed at TAN concentrations of 1, 2, 3 and 4 mg/L under
salinities of 15 and 30 ppt for 12 hr.   Percentage TAN removal was maximum when the
total ammonia concentration was 1 mg/L. There was no significant difference in
nitrification rates at different salinities whereas the rates differed
significantly (P
