Water treatment

Water, if untreated, contains chemicals and bacteria that can lead to scaling, corrosion and bio-fouling within closed systems. In turn, this can cause inefficient systems and necessitate early replacement of plant.


  • Prevent scaling, corrosion and bio-fouling

    Certifact are specialists in chemical water treatment and offer a full range of services to prevent scaling, corrosion or bio-fouling in heating and chilled water pipework.

    Scaling will reduce efficiency and cause process system blockages whilst corrosion will shorten system life and potentially mean the replacement of costly plant and equipment.

    Bio-fouling can cause blocked systems and, through various micro-organisms, present significant health implications including Legionella.
