Abstract
A system to remove contaminants from contaminated water contains a pre-concentrating subsystem, a contaminant removal subsystem or a biological subsystem configured to remove two or more contaminants, and a permeate blending subsystem. A process for removing contaminants from contaminated water includes concentrating contaminated water, treating concentrated contaminated water, and combining product water to produce environmentally acceptable product water.
