Abstract

The following paper aims to inform the readers about various hazardous wastes like solid waste, liquid waste and air pollutant generated in lead acid battery industries, harmful effects of those wastes and necessary treatment needed to neutralize those hazardous wastes. Efficient methods of neutralizing those hazardous wastes to reduce the harmful effects on both human and nature are shown here. Considering ISO 14001:2004 some treatment plants like effluent treatment plant (ETP), air treatment plant (ATP), and Fume Neutralizer Plant are essential for neutralizing those hazardous wastes. The performance of those treatment plants are evaluated by checking out important parameters like PH, total dissolved solids (TDS), biological oxygen demand (BOD), chemical oxygen demand (COD), chlorides and other heavy metals. Here the limits of those parameters of effluent both before treatment and after treatment are shown and finally some recommendations about waste management are given in the conclusion section.
