Performance of modified bio-filter on physico-chemical properties of water samples of Naini, Allahabad

Abstract

The experiment was conducted to know the working performance of modified biofilter for different physico-chemical properties of water samples from different sources at Naini, Allahabad. The percent variation in deferent parameter after purification was found significant, the parameters viz pH, EC, temperature, Calcium Hardness, Turbidity, TDS and Chloride after purification by biofilter were found under the permissible limit as per BIS standard. The total hardness, magnesium hardness after purification were found beyond the permissible limit in all water samples and Arsenic were also recorded beyond the permissible limit in water samples contaminated as 10 ppm and 20 ppm Arsenic Artificially. The performance of Biofilter was highly effective in removal efficiency and balancing of different water parameter. Percent variation in all parameter ranges from minimum 0.70 - 0.84% and maximum 80% - 91%.
