Tainted Wastewater Remediation through Inverted Multimedia Biofilter

Abstract

The growth of industry leads to the contamination of surface as well as groundwater. Improper industrial wastewater disposal causes a serious problem of metal accumulation in the soil and freshwater. To tackle this issue there is a need of recycling and reuse wastewater using low-cost sustainable treatment. The main objective of this research is to check the feasibility of multimedia vermifilter for the efficiency removal of physicochemical parameter and fluoride metal ions of fluoride-tented used water (wastewater). For the treatment, we used fluoride contaminated used water (wastewater) from the fluoride contaminated site. In this study multimedia vermifilter integrated with moringa seed extract, activated charcoal powder, and earthworm Eisenia fetida were used as bio-media to treat contaminated used wastewater, In this experimental analysis, we checked the removal efficiency on different HLR in m3/day/m2. The result showed that percentage removal efficiency for BOD, COD, TDS and Fluoride using inverted multimedia filter was observed for the optimized hydraulic loading rate at 0.933m3/day/m2 was found to be BOD (81.64%), COD (51.47%), TDS (82.17%), Fluoride (35.81%) respectively. The earthworm, moringa seed extract, and activated charcoal play a vital role in the removal of Bioconversion of organic matter. Furthermore Treated effluent waste-water is then used for gardening and irrigation purposes.
