Design Guidelines of Establishing Modified Integrated Pond Arrangement System (Mipas) for Effective Treatment of Wastewater in Katni District of M.P

The present work done was concerned with the study and checking of the suitability of establishing waste stabilization ponds (WSPs) for treating wastewater in Katni Dist, of M.P. where the proper options of municipal wastewater treatment facilities does not exist. The work comprised of setting up pilot scale Modified Ponds in a manner to facilitate the treatment process in lesser time with better treatment efficiency. Experimental work had two cases depending on many considerations such as economical and specification of final effluent. A conventional model of three ponds in series was used as first case of experimental work. Then in the second case the first pond was changed from conventional to modified pond ? High Rate Anaerobic Pond (HRAP) with a plastic screen. At last, a settling pond was used to polish the final effluent by removing the solids. The whole system was named as Modified Integrated Pond Arrangement System (MIPAS). The three ponds settled up had different surface area with different depths, where it was 1.5m for anaerobic pond, 0.5m for facultative pond and 0.25m for aerobic pond. From the tests taken for the two cases which included analysis of pH, Total solids, Total Suspended Solids, Biochemical Oxygen Demand and Faecal coliform concentration, the results obtained for the second case was much better when compared with first case. Settling pond (basin) contributed in improving final effluent by decreasing total suspended solid (TSS) also in increasing removal efficiency of biochemical oxygen demand (BOD). At the end, the results of this work could be taken as an invitation to establish and use waste stabilization pond for wastewater treatment in rural areas or even small communities but it may need more examinations to get best results.
