Full Treatment Range Tailored to Your Requirements

Prowater can supply a wide range of water treatment chemicals to prevent scale, corrosion and biofouling to any sort of water treatment equipment , industrial plant or domestic services.

Scale

When you apply heat to water containing calcium and magnesium hardness salts, the hardness comes out as scale. It doesn't matter whether it's a kettle, dishwasher, boiler, calorifier, cooling system of even pipe work - the result is the same - deposits of fur or scale that restrict water flow and contribute to poor heat transfer.

Corrosion

In most cases dissolved oxygen is the primary cause of corrosion although 'mixed metal systems' can also suffer from corrosion through galvanic action. Corrosion eats away costly system components and corrosion products can cause staining and sludging. If precommission cleaning has been missed or carried out incorrectly, then mill scale, rust, grease and other residues can cause severe operating problems.

Fouling

Most systems provide ideal conditions for one or more of the common micro-organisms such as bacteria, fungi and algae to multiply quickly and cause organic fouling. Apart from the obvious problems of blockage and poor heat transfer, organic fouling present an inevitable health hazard.

Prevention

In many systems chemical scale suppressants give excellent results but for hard water areas, such as London, the most cost effective method is soften the incoming supply. Capital outlay is recovered quickly because of lower maintenance, labour and cleaning costs. You save on water costs tower bleed-off.

Chemical inhibitors give protection by coating metal surfaces with a microscopically thin protective film. The range of inhibitors is considerable - from those which are D.O.E and W.H.O approved for portable, cold and hot water services to special low toxic inhibitors for heating and cooling systems to meet todays increasingly tough pollution standards for system discharge.

Current guidelines from expert bodies recommended that systems should be regularly disinfected and kept clean and deposit-free. In cooling systems organic fouling should be controlled with selected biocides with proven effectiveness against Legionella bacteria. If these conditions are to be met, then a full program of treatment is needed to give effective control, not just of fouling, but of scale and corrosion as well.
