Jesco and Technopool – a long-standing partnership in the use of flow-through electrolysis for the extraction of chlorine from the salt dissolved in water as a disinfectant in swimming pools. They have combined the excellent properties of salt with the SALT WATER LIGHT process for the production of chlorine by salt electrolysis, which was awarded the German Federal environment prize in 2005. The electrolysis takes place within the swimming pool system itself and thus avoids the need for the storage and movement of chlorine-containing disinfectants.
