Physicochemical characterization of tannery effluent and its treatment using Eichhornia crassipes - A Phytoremediation study

  Shehnaz Begum. T,  Vijayalakshmi.M

Tannery effluent contains large amount of chemical compounds including toxic substances. So an attempt was made to characterize physicochemical parameters of tannery wastewater and investigated the efficacy and applicability of the biological treatment utilizing aquatic plants. pH of the effluent before the treatment was 6.8 and it was increased to 7.4. An increase in pH value supports the growth of aquatic plant. Physico chemical parameters like BOD (Biochemical Oxygen Demand), COD (Chemical Oxygen Demand), TDS (Total Dissolved Solids), TSS (Total Suspended Solids) and Total Chromium in the effluent before the treatment was 830, 1765,4640,1560 & 15.96 mg/l respectively. Minerals present in the soil at the discharge of tannery effluent were also analysed using XRF (X-ray Fractionisation). Biological treatment with aquatic plant was found to be effective for the reduction of some physico chemical parameters. E.crassipes was found to be most effective in reducing BOD, COD, TDS, TSS and Total Chromium. E.crassipes was identified as most effective for the removal of chromium in the tannery effluent because of its extensive root system which provides to help the uptake of the pollutants from the industrial effluent.

Keywords- Tannery effluent, Physico chemical parameters, E.crassipes and XRF.
