In the hot dip galvanizing facility where steel materials are subjected to a series of treatments, effluent is generated in the form of spent acid and wash water from degreasing, pickling, and fluxing units. Corrotech designs specialized Effluent Treatment Plant for treating the effluent by considering the characteristics of the generated effluent.


Owing to our huge infrastructure and domain expertise, we are able to manufacture and supply premium quality ETP plants that meet the exact requirement of your galvanizing unit. Considering the key characteristics like the flow rate as well as physical, chemical, and biological characteristics, we come up with a design that gives optimum treatment efficiency. The ETP Plants constructed by Corrotech comply with the industry-laid parameters.

Effluent Treatment Plants by Corrotech ensure efficient handling of spent acid and acid rinse as it is equipped with modern technology to perform treatment in every phase. Corrotech’s ETP plants are equipped with a set of state-of-art systems that take complete care of no spillages on earth, the storage of sludge in the landfill, and the end treated effluent meeting the standards prescribed by CPCB.
