This case study explores how QUA’s Q-SEP Ultrafiltration Membranes effectively treat complex effluent at a leading greenfield integrated steel plant.
QUA's Q-SEP Ultrafiltration Membranes
Challenge
A leading greenfield integrated steel plant with an existing effluent treatment plant (ETP) capacity of over 3.4 million gallons per day (approximately 13,000 m3 per day) faced the dual challenge of optimizing wastewater treatment for reverse osmosis (RO) feed for the site’s zero liquid discharge (ZLD) plant while adhering to established pollution control standards and guidelines for treating and releasing wastewater.
Solution
The original treatment system installed by a previous vendor underperformed and failed to function correctly within two months post-installation, prompting the client to decommission it. The client turned to QUA for its expertise and proven solutions.
After a comprehensive evaluation, the client selected Q-Sep 8012, a state-of-the-art low-pressure hollow fiber ultrafiltration system known for its superior performance. The decision to implement this advanced technology was made based on its robust secondary treatment capabilities, exceptional performance, ability to handle a Silt Density Index (SDI) of less than 3, and its proven effectiveness in water treatment applications.

Results
Since its commissioning in April 2023, the ultrafiltration system has delivered uninterrupted, high-performance results. The system has consistently treated effluent treatment plant water, consistently achieving the client’s stringent quality specifications. The clarity of the product water has consistently remained between 0.1 to 0.23 Nephelometric Turbidity Units (NTU), and the permeate flow has been consistently sustained at 267m3/hr in each stream without any reduction in overall output. The RO permeate is effectively utilized for the power plant application.
