Abstract:
The present study analyzed the efficacy of a wastewater treatment model developed with a four-stage treatment system consisting of storage, sedimentation, filtration and chlorination as independent treatment units. Samples at periodical intervals were subjected to water quality parameter analysis viz. pH, colour, turbidity, total dissolved solids (TDS), biological oxygen demand(BOD), chemical oxygen demand (COD), total coliform count and E. coli count. It was observed that pH, color, turbidity, TDS, BOD, total coliform count and E. coli count were within the standard limits, whereas COD level of chemical treated water was observed to be higher than the standards. The results of present study proved that wastewater which has passed through all the four treatments had a quality standard comparable to Indian Standards. It can be concluded that the four-stage treatment system was effective for water recycling in small holder pig production systems.
