One of India’s largest breweries approached SUEZ for a wastewater treatment solution for their manufacturing facilities in northern and western India. The wastewater had high biochemical oxygen demand (BOD) and chemical oxygen demand (COD). The treated water quality required by the company was of reuse standards.
SUEZ created custom solutions for the plants that feature SUEZ’s membrane bioreactor (MBR) technology. MBR provides efficient effluent treatment by removing the dissolved organics that cause BOD and suspended materials in wastewater. The systems replace sedimentation and tertiary filtration in conventional wastewater treatment systems by providing an absolute barrier for the removal of suspended solids.
The ZeeWeed MBR systems can operate with the membranes directly in the bioreactor tank, eliminating the need for secondary clarifiers, and drastically reducing the plant footprint.
Screened wastewater flows to the bioreactor where mixed liquor suspended solids (MLSS) are maintained by ensuring proper aeration. This degrades the BOD and other biodegradable contents of the wastewater. The process aeration blowers provide air for the biological tank and ensure sufficient oxygen is available to maintain the biological processes in the tank. The mixed liquor from the bioreactor flows to the membrane tank by gravity. A one train ZeeWeed 500 ultrafiltration (UF) system is installed in the membrane tank. Periodically, activated sludge is wasted to maintain the desired solids retention time (SRT).

|Location:||Northern and Western India|
|Feed water Source:||Effluent water|
SUEZ’s solution reduced the total suspended solids (TSS), BOD, and chemical oxygen demand (COD), providing treated water as per the reuse standards of the brewery.
SUEZ is a pioneer in the use of hollow fiber membranes for water treatment, with more than 100 drinking water and over 220 wastewater installations globally.
