dc.description.abstractThe village ponds in Punjab state had great importance and these were considered as the gift to the mankind. Quality of village pond water is degraded and not used for irrigation therefore; it is desirable to develop a technology to reuse the village pond water and to make village pond water suitable for irrigation. Thus, the study was planned with the objective of improving the village pond water quality using filter media and make that water fit for irrigation. Five materials viz. biochar, activated charcoal, zeolite, fine and course sand were individually tested for the quality improvement of the village pond wastewater. The water quality parameters such as BOD, COD, TDS, TSS, TS pH, and EC were analyzed before and after passing through the filter media. Uncontrolled flow of water at media depth 30 and 40 cm and water head of 10, 20 and 30 cm was passed through each filter media and discharge was collected for the analysis. BOD was decreased by 12% for activated charcoal, COD decreased by 9.7%, for zeolite, TSS decreased upto 28% by fine sand and TDS decreased upto 13% by fine sand. To further enhance the performance of the filter materials, the study was conducted with the controlled discharge of 5 and 8 l/h through the same thickness of filter media. Result concluded that the discharge rate of 5 l/h, material depth 40 cm and water head 10cm decreases the values of BOD, COD, TSS and TDS more efficiently than uncontrolled flow of water and for discharge rate of 8l/h. The 40cm depth of material was found more efficient than the 30cm depth of material whereas there was insignificant difference in the efficiency at 10, 20 and 30 cm head so 10 cm head along with 40cm material depth was selected. Efficient materials based on the removal efficiency was selected (zeolite, activated charcoal, biochar and fine sand) and each selected materials were put in the column one over the other as a depth of 40 cm each by keeping course material at the bottom and finer at the top and water head 10 cm. Two cycles of 24, 48, 96 and 168 h duration was performed and effluents were collected at the outlet and again parameters were determined. For combination of materials during first wet cycle at 24, 48, 96 and 168 h samples were collected and analysed for all parameters and efficiency of 49%, 57%, 75% and 10% was achieved in terms of BOD, COD, TSS and TDS. Whereas for second cycle the values were 44%, 56%, 63% and 6% which showed that there is decrease in the values of efficiencies than first cycle.en_US
