The client is a wholly owned Indian subsidiary of one of the world’s largest automobiles conglomerates. The Indian subsidiary is one of the largest manufacturer and exporter of passenger cars in India.
The client had set up a new plant and was looking to expand their ETP to treat the increased effluent. Ultrafiltration was required in tertiary treatment to provide consistent product water with low silt density index (SDI), to safeguard downstream Reverse Osmosis (RO) unit from colloidal fouling. The feed turbidity to Ultrafiltation (UF) unit varies from 5 NTU to 20 NTU. QUA’s Q-SEP Ultrafiltration modules successfully met the plant’s requirements due to their low fouling characteristics, uniform pore size distribution and large surface area which provides high operating efficiency and reliable operation. The Q-SEP system follows a pretreatment process comprising of a dual media filter followed by a bag filter, and precedes a reverse osmosis treatment system for tertiary treatment.
