EE021 – Sampling, Analysis and Design of Effluent Treatment Plant for Leather Industry


In India, tanning is a little scale industry. All through the tanning procedure, monstrous measure of wastewater is produced and as a rule it contaminates nature. The waste materials from the tannery business are portrayed by high oxygen request, add up to broke up solids and risky inorganic substance squander, and so forth. The structure of the Effluent Treatment plant under investigation, includes a mix of essential, auxiliary and tertiary treatment forms.

The overall extent of profluent produced in various phases of tanning was observed to be high in de-liming and goading (26%) while bring down in pickling (4%), which created semi-completed cowhide item. The think about was performed with respect to the investigation of water quality parameters. Essential treatment has most extreme values while contrasted with the last stage, for example, tertiary treatment.

The pH extended from 10 to 6.6; temperature from 27.6 to 28.3°C; TSS from 1582 to 26.3 mg/L; TDS from 2558 to 2500 mg/L; chlorides from 1476 to 1407 mg/L; oil and oil from 65.8 to nil mg/L; COD from 1819 to 157 mg/L and BOD from 810 to 55 mg/L individually. In this manner a basic report on the idea of mechanical squanders, treatment procedures and it is basic highlights was surveyed to keep up a maintainable situation.
