Less than two years after its foundation, Mumbai-based H2O Innovation India Ltd. has commissioned its first major water treatment system. Designed, assembled and installed for the nuclear forging facility Larsen & Toubro Heavy in Hazira, India, the system combines ultrafiltration and reverse osmosis technologies.
Fed with Tapi River water, the membrane filtration system has total capacity exceeding 7,000 m3/day (approximately 1,321 gpm). Purified through reverse osmosis, the water then is used as process water for the steel-forging facility, but subsidiary treatment systems also provide for compressors, cooling towers and steam boilers. The system's global recovery rate reaches 90 percent, according to H2O, which reduces losses in the arid region. The system uses automatic pre-filters from Amiad in Oxnard, Calif., PVDF ultrafiltration membranes from Dow Water & Process Solutions in Edina, Minn., and ESPA2-LD reverse osmosis membranes from Oceanside, Calif.-based Hydranautics.
To reduce noise, the system’s feed and recirculation pumps are below ground, which is unusual in India.
"The technology transfer between H2O Innovation and our Indian joint-venture has been instrumental for the execution of this project, and it will remain a key factor for our future achievements in India,” says Guillaume Clairet, H2O vice president of strategic business development.
