Treatment process for produced water and blowdown water

Abstract

This invention provides processes for treating a mixture of produced water and blowdown water comprising introducing produced water (PW) into blowdown water (BD) for forming a PW-BD water mixture, softening the PW-BD water mixture, subjecting the PW-BD water mixture to activated carbon filtration and reverse osmosis membrane desalination. The process generates a product water and a brine by-product.
