Application of jug filters for the treatment of model well water

Abstract

This study evaluates the performance of treatment of model well water by means of home water filtration with overflow filters. Treatment efficiency was determined by measuring physicochemical parameters such as water hardness, conductivity, and iron, manganese and endosulfan concentration. The microbiological performance of the jug filter was also assessed. Model well water was prepared by spiking iron, manganese and endosulfan to tap water. Daily filtration of 5 L water batches was performed for a period of 1 month. Test samples of the filtered water were taken twice a week, and each filter was tested 3 times. Depending on the water filter, manganese and iron were reduced by 50%–70% and 96%, respectively. Removal of endosulfan reached the maximum level of 90%. Disease-producing bacteria (Coliform bacteria, Escherichia coli) were not detected in the filtration period of 4 weeks. Filters stored in the refrigerator revealed better microbiological performance, as the multiplication of bacteria was lower than for filters stored under ambient conditions. The disadvantage of the filtration processes was a reduction of the filtration flow rate.
