Scale and fouling

WebTypically, the most cost effective solution for controlling Scale and Fouling is to implement a chemical treatment program using Scale Inhibitors (phosphonate and/or phosphate) in conjunction with a Dispersant. Successful programs include monitoring and regular testing of the water quality to validate the effectiveness of the chemicals being used. WebScaling or precipitation fouling involves crystallization of solid salts, oxides, and hydroxides from solutions. These are most often water solutions, but non-aqueous precipitation fouling is also known. Precipitation fouling is a …
