The present work investigated biofilm development and process parameter in the nitrification of a synthetic saline wastewater in reactors known as submerged aerated biological filters. The support used for biofilm development was made of PVC wrinkled plates with large specific area and high porosity. Biofilm development on the support was investigated by cultivating the mixed culture batchwise. in the first week of operation, a brown biofilm was macroscopically evident on the support surface. After 10 days the biofilm activity became stable and ammonia removal rate was observed and the attached biomass reached a maximum value. when the system was operated continuously, with a hydraulic retention time of 15 h, the removal efficiency observed was 94% in the obsence of NaCl and 48% in the present. |
