GRINTEK was founded in 1996. It is based in the Nuclear Physics Institute (Tashkent, Uzbekistan). We develop and produce any industrial water filters, including mechanical water filters with reverse cleaning, systems of fine water filtering, ultraviolet disinfectors of water and electrochemical water disinfectors, industrial water softeners with chemical treatment of water for mechanical rooms, industrual reverse osmosis systems (based on VONTRON membranes), sewage water treatment systems, modular water treatment systems. We also produce and sell fibrous cation- and anion-exchange sorbents for water and air purification. We perform a legionella (and other bacteria) water risk assessment in air conditioning and water supply systems of hotels and health resorts. We also develop and realize risk minimization plans.
