Open Circulating Cooling Water Treatment
Product Data (PD) and Safety Data Sheets (SDS) are available upon request
Industry uses large quantities of water for the cooling of its processes. Cooling Towers are for the most prevalent method of achieving this economically and in large volumes.
Whichever Cooling Tower design is used there are three principle objectives in treating cooling water and all are interrelated and can be summarised :-
• To prevent Scale, formation on the heat exchange transfer surfaces
• To prevent Corrosion of metal surfaces in contact with the cooling water
• To prevent Biological fouling organisms or suspended deposits in the cooling water
The Cooling Tower system circuit will comprise of a Cooling Tower, Circulating pumps, Heat Exchangers and connecting pipework.
Cooling Towers are a type of heat exchanger that allows water and air to come into contact with each other to lower the temperature of the process or system water. This allows for a system to cool down and may be in association with other water treatment equipment such as Chillers or Industrial process cooling.
The cooling tower of an open circuit acts as a giant vacuum cleaner, scrubbing the air that is drawn into it, retaining the airbourne material within the recirculating water. This is a continuous operation and the suspended matter will build up deposits on the internal surfaces of the system seriously affecting the efficiency of the heat exchangers and the free circulation of the water. At the same time additional deposits caused by corrosion products and microbiological growth within the system will add to the fouling problem. The result of this deposition will be an increased water demand in an endeavour to maintain the design level of heat removal from the system. The introduction of a complete, planned water treatment programme is essential to overcome these problems.
