Larsen & Toubro – Tecton JV has installed FilmTec™ Reverse Osmosis membranes with Inge® ultrafiltration technology in a 100 MLD plant in Gujarat.
WD News: DuPont has announced that its FilmTec™ membranes and Inge® ultrafiltration membranes were installed in a multi-tech Seawater Reverse Osmosis (SWRO) desalination plant for industrial use built by Larsen & Toubro -Tecton JV at Dahej for the Gujarat Industrial Development Corporation (GIDC) in India.
The plant, which recently became operational, provides 100 Million Litres/Day (MLD) of water exclusively to the Petroleum, Chemicals & Petrochemicals Investment Regions (PCPIR) industries in the Dahej district – meeting approximately a quarter of the local industrial water demand.
These industries are highly dependent on fresh water and have faced major production issues due to water scarcity during the summer season, as well as rising salinity of the Narmada River. More than 190 businesses in the PCPIR sector will benefit from the water security provided by this plant.
In 2019, Larsen & Toubro – Tecton JV was awarded the EPC contract to build a 100 MLD desalination plant for GIDC. The JV chose DuPont Water Solutions (DWS) to supply membranes for this project – with a multi-technology approach to desalination that leverages a combination of Reverse Osmosis (RO) membranes and Ultrafiltration (UF) modules.
In addition to providing more than 2,000 Inge® UF modules, DuPont also supplied more than 10,000 FilmTec™ Seawater and Brackish water RO membranes – with approximately 75 percent being delivered as dry membranes.
The dry SWRO membranes provided project managers more flexibility and ease of installation.
“This project is a model for how desalination can provide a sustainable water supply for collective industrial purposes,” said Chrys Fernandes, who leads DuPont Water Solutions in India. “We are confident this project will encourage other industrial zones to commission such plants to meet their water demands in the face of water scarcity and quality challenges.”
