Pre-Treatment And Post-Treatment Of Leather Industrial Effluent By Microalgae: A Comparative Study

Abstract

For many years, tannery industries have been a vital part of a country's economy. The untreated industrial effluent discharges, the solid waste and waste water generated during the leather manufacturing process are developing threats to the environment day by day and the prevailing management monitoring system of wastewater is inadequate. This research work includes the treatment of effluent arising out of a tannery business near Pallavaram employing  indigenous microalgae. The characteristic values of the typical raw effluent parameters were analysed and compared to the values of  phycoremediated effluent parameters,  the results confirmed that the treated effluent had acceptable amount of  physical and chemical features, along with heavy metals concentrations within acceptable limits.
