Abstract

A sterilizing plant for water is claimed in which a chemical sterilizing agent is dosed into a water system in quantities regulated to suit requirements; the agent is introduced by ejector action of the water flowing in the system to be treated. Ejector suction is pref. obtd. in a by-pass line connecting two points at different pressures in the water sytem being treated. Pref., agent is supplied to the ejector inlet in a flow of mains water passed through an agent reservoir each time a solenoid valve is opened in response to a signal from an indicating galvanometer actuated by a measuring cell continually sampling water from the system to be treated. Use continuously sterilizing water in circulating systems, partic. for swimming pools. No electronics in instrument system and no pump to inject sterilizing agent - hence, reduced maintenance requirements, increased reliability and lower costs.
