Abstract
Disclosed is a method of inhibiting and/or removing deposits from internal surfaces in a hot water system. The method includes controlling a real-time oxidation-reduction potential in a hot water system to alter the dynamic between deposit constituents and the bulk water of the system to inhibit deposition or initiate deposit removal. The method is equally effective for a system undergoing a wet layup sequence or in an online operational system. The invention further includes a multi-component deposit inhibition and/or removal device, including a receiver, a processor, and a transmitter that work in unison to alter the system dynamics to inhibit or remove deposits.
