NEW TREATMENT FOR INDUSTRIAL WASTEWATER OF BATTERIES INDUSTRY

Abstract

The environmental pollutions which produced from the rapid industrialization become a serious issue, and therefore efficient methods are needed for the different industries. The Heavy metals have stated as urgent pollutants, because of their movement into water ecosystems and because of their toxicity. Many ways managed to remove the heavy metals but with a high cost and therefore there is a need to use a low cost materials and methods for the removal process. This thesis has been carried out to study the adsorption method using a low cost materials (clay, output trimming tree (ficus)) to remove the heavy metal (lead) from the industrial wastewater and comparing them to a high cost material (activated Carbon). The study shows that the removal ratio for each material were 94.66 % with activated carbon, 93.45 % with ficuss trees trimming output and 92.25 % with clay. The study shows that the using of low cost material as clay and agricultural waste as ficus are possible as adsorbent filtration media and they achieve a removal ratio near to the a high cost material as activated carbon which save a lot of cost for industrial wastewater treatment and encourage the factories to use them The study shows that the removal ratio increases as the media depth increases and as the rate of filtration decreases with lead removal ratio up more to 93 % & 92 % for ficus and clay respectively using the materials as Adsorbent filtration media which their cost not high and don’t need a pretreatment before using for the heavy metal removal from the industrial wastewater.
