Patent ID: 7695606

Claim:
An electrolytic device for disinfecting water in a water supply system by generation of active chlorine, consisting essentially of: an electrolytic cell provided with electrodes over which a voltage difference is applied, a generator for supplying the voltage difference for the electrolytic cell, which generator is driven by the water in the water supply system, a supply pipe for the electrolytic cell that is connected to the water supply system and which guides a part of the water flow in the water supply system to the electrolytic cell a discharge pipe for the electrolytic cell that is connected to the water supply system downstream of the location where the supply pipe for the electrolytic cell is connected to the water supply system and which discharges the water treated in the electrolytic cell to the water supply system, a salt dosing device containing a compound capable of supplying chloride ions, a supply pipe for the salt dosing device which is connected to the supply pipe for the electrolytic cell and which supplies at least a part of the water in the supply pipe for the electrolytic cell to the salt dosing device for supplying chloride ions to the water to be treated in the electrolytic cell, a discharge pipe for the salt dosing device which is connected to the supply pipe for the electrolytic cell downstream of the location where the supply pipe for the salt dosing device is connected and which guides the water containing chloride-ions from the salt dosing device to the supply pipe for the electrolytic cell, and means for regulating the ratios of the water flow in the water supply system, the feeding for the electrolytic cell and the feeding for the salt dosing device comprising: constrictions and/or regulating valves accommodated in the water supply system between the location where the supply pipe for the electrolytic cell is connected to the water supply system and the location where the discharge pipe for the electrolytic cell is connected to the water supply system, the supply pipe for the electrolytic cell, the discharge pipe for the electrolytic cell, the supply pipe for the salt dosing device and/or the discharge pipe for the salt dosing device, and a blade wheel connected with the generator for driving the generator and accommodated in the water supply system downstream of the location where the supply pipe for the electrolytic cell is connected to the water supply system and upstream of the location where the discharge pipe of the electrolytic cell is connected to the water supply system.
