Conventional chemical water treatment
1.51 Most cooling systems are treated using what might be termed conventional chemical techniques. This may involve adding inhibitors to control corrosion and scale
formation, biocides to control microbial growth and dispersants to control fouling. These may be in the form of single-function chemicals or multi-functional admixtures.
1.52 The chemical programme can be augmented by pre-treatment of the make¬up water and will include bleed-off control to limit the cycles of concentration. In some instances, acid dosing may be incorporated as part of the scale control programme and in other instances side-stream filtration may be employed to control the build-up of suspended solids.
