HOW IT WORKS

The Watermaid Water Treatment Unit manufactures chlorine biocide, needed for effective water treatment of cooling tower water circuits. Watermaid's  proven chlorination process is by the electrolysis of the naturally occurring salts (chloride ions), already contained in the makeup water of a cooling tower system.

Chlorine has been PROVEN to be an effective biocide. It is commonly added to cooling towers, primarily in the form of liquid chlorine (12.5% available chlorine) or granular chlorine (65% available Chlorine) to kill all micro-organisms, including Legionella species and maintain control within the cooling tower.

The Watermaid Water Treatment Unit manufactures its own chlorine (100% available Chlorine) "on-site"  to maintain the water of a cooling tower in a clean, clear and sterile condition, 24 hours per day, to provide maximum protection for the tower and the general public at large.

The cost of manufacturing "on-site" chlorine by the Watermaid Water Treatment Unit is about 1/6 the cost of purchasing the cheapest chlorine chemicals or other biocides.

The Watermaid Water Treatment Unit differs from other forms of water treatment devices in that:

• The Watermaid Water Treatment Unit manufactures a powerful chlorine biocide, 24 hours per day, every day of the year, giving around the clock protection for the cooling tower. Not once a day, week or month as a dosing maintenance system or serviceman may perform.
   

• The Watermaid Water Treatment Unit - DOES NOT ADD any aggressive, corrosive, chloride ions to the water of a cooling tower system, therefore corrosion is limited to the agents inherently found in makeup water.

(Other forms of biocide treatment for cooling towers commonly involve treating the water by adding liquid chlorine, granular chlorine, halogen compounds and powders, sulphur dioxide, hydrogen peroxide and non-oxidising biocides, ALL of which contribute chloride ions to the water, responsible for corrosion problems in cooling towers.)
