Scale & Corrosion Control

Scale and corrosion affect both drinking water and industrial plants. Scaling is the formation on a surface of a regular crystal lattice structure of marginally soluble salts. Scale can be very thermally insulating. In addition to scale formation, some salts precipitate in an amorphous way, that is, in a non-regular way. This can include microbiological slime which may be the ‘glue’ that holds the amorphous salts together.

Corrosion is Nature’s way of converting refined metals back to its original state. This is a thermodynamically favored process, and the best man can do is to attempt to control the type of corrosion that occurs and to slow the corrosion process down. Two types of corrosion exist, general and localized. Generalized corrosion is where the entire metal surface is corroded away at a constant and predictable rate. This is the most desirable type of corrosion. Localized corrosion occurs for a variety of reasons, and is undesirable because the corrosion is localized to one place, and the rate is not predictable, generally. The type of corrosion which occurs under a deposit, for example, is under-deposit corrosion, which is a localized corrosion. Thus minimizing scaling and deposition is absolutely necessary to control corrosion.
