An auto ancillary plant in Chennai, India was in need of a new pretreatment system for their effluent treatment plant (ETP). The client had installed an ETP to treat the wastewater generated from their auto ancillary unit. The ETP provides complete pretreatment along with biological treatment. However, the ultrafiltration membranes were not able to perform due to challenging feed parameters which caused rapid fouling and required frequent cleaning. This problem hindered production for the client so they looked to QUA for a speedy and reliable solution.
The client’s current tertiary treatment system is comprised of ultrafiltration (UF) followed by a reverse osmosis (RO) system. The waste generated from the tertiary treatment plant is further treated by the zero liquid discharge system for the purpose of recycling the treated water back into the process stream.
