ABSTRACT:
A method and device for protecting an aqueous system from scale precipitation by depressing scale precipitation in a bulk phase of a water supply, the device including: (a) an electrolytic cell for fluidly connecting to the system, including: (i) a tank for receiving the water supply, the tank having a copper surface forming a cathode of the cell; and (ii) an element having a zinc surface disposed within the tank, and forming an anode of the cell; (b) a controlling unit for controlling a current (I) from the power supply; and (c) a flowmeter for measuring a flow rate of the water supply, the flow rate associated with a flow rate of water into the system, wherein the controlling unit is designed to control the current according to the flow rate so as to depress the scale precipitation in the bulk phase of the water supply, and wherein the current I exceeds (1.84−A)*Q and is less than (1.84+A)*Q, wherein I is measured in amperes; Q is the total flow rate (m3/h); and A is a positive number and less than 1.05.
