| Abstract | Wastewater treatment is an urgent demand of the present world for human survival, resource management, environmental quality and sustainability. Sequencing Batch Reactor (SBR) is well adopted for community wastewater treatment for its simplicity, performance and various advantageous treatment options. Sequencing Batch Reactor is now drawing attention for its process modification such as coupled with membrane bioreactor, reverse osmosis or applying different media to achieve high removal efficiency. Our study focused on the improved efficiency of carbon, nitrogen and phosphorous removal by applying zeolite materials called bio-ceramics to the SBR. Thus two SBRs were operated one with bio-ceramics and the other without bio-ceramics used as control. Routine monitoring of COD, TP, NH3-N, N03-N was performed throughout this study. COD removal was observed about 80% to 100% and phosphorous removal about 60% but for NH3-N removal, the efficiency was about 99 .9%. The addition of bioceramics improved Total Phosphorous (TP) and COD removal in the BCSBR process. Some other effects were found on the sludge characteristics e.g. sludge dewaterability and specific gravity and particle size. Absorption/adsorption or desorption capacity of bioceramics was tested through laboratory experiment. It was found that the bio-ceramics had small absorption and desorption capacity. As the cause of the improved nitrogen removal to adsorption/desorption of ammonia could not be attributed to bio-ceramics in the present study, further study is recommended to clarify these mechanisms. It would be mentioned that the quantity of bio-ceramics added in the reactor was not so much. There is enough scope of future research using higher quantities of bio-ceramics than this study. Nitrogen balance in the influent, effluent and inside the reactor is an important aspect of further study. |
