Study Of Microbial Impact On Lead Remediation In Industrial Wastewater
Main Article Content
Abstract
Heavy metal burdens in wastewater have increased as a result of industrial and development activities, and their inadequate treatment before disposal poses serious environmental problems. Lead (Pb) is a highly toxic heavy metal that is commonly utilized in a variety of sectors, including paint, batteries, electroplating, tanneries, paper and pulp mills, textile mills, smelting, and mining. As a result, excessive amounts of lead are produced when disposing of effluent from these industries. Lead's potential for bioavailability poses a health risk to youngsters and results in mental retardation. This heavy metal must be removed from industrial effluents before they are released into the environment and natural land or water. Pb treatment in industrial wastewater is being done using a variety of conventional procedures. These techniques' primary limitations are their limited effectiveness and lack of technical proficiency. The widespread acceptance and low cost of microbial Pb treatment of industrial waste water has recently established as a feasible alternative. It is advised to use biotechnological methods to recover metals from the effluents (which are heavy metal-rich) that are dumped into ponds. Heavy metals will be removed by the microorganisms, who will then enclose them inside of their cell membranes. Hazardous metals can be degraded or converted into simple, harmless compounds through the process of bioremediation. In the present study, the role of Pb microbial remediation in industrial wastewater is comprehensively analyzed.
