Abstract:

One of the major challenges faced in present scenario is the treatment of wastewater produced during industrial process. Various effluent treatments are adopted for achieving the discharge standards. Different technologies like RBC, ASP, trickling filter, SBR are used for removal of BOD, COD, and TAN etc. We need to adopt such technology to meet with the standards made by CPCB to maintain the environment of the aquatic life. The discharge standards for industrial BOD, COD and TAN are 100 mg/lit, 250 mg/lit and 50 mg/lit respectively. In this project, we have gone through theoretical comparison between aerobic, anaerobic treatments; attached and suspended growth, moving bed and fixed bed reactors. Analysis of various parameters like COD, BOD, TDS, pH, NH3-N+ of the ASP stream. MBBR presents several operational advantages like less HRT, smaller footprint; this technology gives us low concentration of solids leaving the biological reactors and good settling characteristic of sludge. Various trials at different flow rates were carried out to get optimized flow rate.
