Abstract

A device has a storage tank for preparing an electrolyte, a pump delivering the electrolyte to a reactor with an anode and a cathode, and a pipe for injecting the electrolyte leaving the reactor into a water supply pipe. An outflow meter measures the flow rate in the supply pipe. A controller controls the current intensity between the anode and cathode and the injection rate of the electrolyte. An Independent claim is included for the following: (a) Continuous treatment of water using the above treatment device where the operation of injection pump is controlled in relation to the water flow rate in the pipe. Preferred Features: The controller responds to the flow rate of cold water in the supply pipe. The storage tank includes a pH controller. The reactor is a cylinder about 300 mm tall and an external diameter of 300 mm. It contains an inner cylindrical anode surrounded by rod shaped cathodes. In operation, the reactor produces free chlorine having a concentration in the water to be treated of 2 - 3.5 mg/l.
