Available Techniques of Wastewater Management Practices in Indian Tanneries: A Literature Review Service Unavailable

Tanning is the process of turning animal hide into leather. The manufacturing process leads to the generation of wastewater, which must be treated before discharge. The treatment processes of this wastewater in India was examined. A systematic review based on Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines was carried out on the electronic database Google Scholar from ۲۰۱۰ to ۲۰۲۰. Wastewater treatment practices in Indian tanneries were looked for and ۶۴ relevant reports and articles were shortlisted and studied. The results showed that coagulation with alum and ferric chloride gave the best results in primary treatment, aerobic and anaerobic processes gave the best results when combined, and tertiary treated water could be reused.Tanning is the process of turning animal hide into leather.
