Sodium Hypochlorite Level Measurement in Water Disinfection Systems
UK water companies process and deliver billions of cubic metres of drinking water each day. For disinfection treatment, on-site sodium hypochlorite solution generation is increasingly regarded is a cost-effective, reliable and safe alternative to sourcing chlorine from a chemical distributor; it reduces the need for bulk storage equipment and the risks associated with handling and holding large quantities of chlorine.
At this pumping station the Flowline EchoPod DL14 level sensor is measuring sodium hypochlorite that is generated to disinfect well water that is then distributed to surrounding residents. The EchoPod DL14 is installed on the storage tank, providing continuous level measurement data to the chlorine generation controller. As level falls, chlorine production is increased; as it rises, production is slowed and ultimately stopped when full.
