Nirma is a multi-sector FMCG brand, headquartered in Gujarat in western India. Nirma manufactures products ranging from cosmetics, soaps, detergents, salt, soda ash, lab products and injectables. It is not only the largest selling detergent brand in India but also world number one in soda ash capacity. Nirma has about 18,000+ employees and annual turnover of $1.1 billion (Rs. 7,000 Crores).Gujarat is a water scarce region and Nirma wanted to treat seawater to augment water supply at their plant and reduce dependence on rain water. When Nirma expanded their facility to include a new soda ash plant and a new power plant, they had an increased requirement for fresh water, and selected Aquatech as the EPC contractor to design and supply the new 25 MLD Seawater RO system. Aquatech selected QUA’s Q-SEP® hollow fiber membranes as the pretreatment to SWRO system because of the unique features the membrane offers.
Q-SEP® Model: Q-SEP® 6008
Total Q-SEP® Membranes: 170
Permeate Flow: 510 m3/hr
Application: Seawater Treatment
Q-SEP® Ultrafiltration (UF) skid for Nirma comprises of 170 membranes arranged in a five row configuration with each row having 35 membranes. The sub headers of individual rows are connected to a main header.
QUA’s Q-SEP® membranes are able to produce water with a low silt density index (SDI) due to their narrow pore size distribution. The lower product SDI leads to less frequent and easier cleaning of downstream RO membranes. Q-SEP’s ability to provide high quality water for RO systems allows it to be an integral solution for seawater desalination systems.
