TREATMENT OF LIQUID WASTE FROM SOME CHEMICAL ANALYSIS LABS

Abstract

Chemical laboratory disposed of their liquid wastes to the sewage network without treatment. They contain hazardous materials that harm the environment. The growth of industrial activities has caused a number of environmental problems. Over the decades, many chemicals have been consumed periodically, thus increasing the volume and quantity of these wastes containing heavy metals, harmful substances that are discharged into the drainage networks with different types and forms (gas - liquid - solid), a danger to humans and the environment. This work aims to remove heavy metals from inorganic effluents resulting from inorganic analytical chemistry laboratories before being discharged into the public sewage network. - Obtaining the optimal operating standards for the remova
