Services and Products - Cooling Water Treatment
Evaporative cooling equipment works by the evaporation of a small percentage of the recirculating water. This process removes heat from the remaining water allowing it to be re-utilized for cooling purposes. Any impurities present will remain in the recirculating water and their concentration can increase rapidly to reach unacceptable levels. Airborne dust and dirt may also be introduced into the recirculating water, intensifying the problem.

If impurities and contaminants are not effectively controlled, they can cause scaling, corrosion and sludge accumulation which reduce heat transfer efficiency and increase your operating costs.

The cooling water also provides the ideal environment for the growth of many micro-organisms, including legionella bacteria; the bacterium which causes Legionnaires'disease.

Legionnaires' disease is an uncommon but serious form of pneumonia. Although Legionnaires' disease remains rare, cooling towers are the major source of outbreaks. All owners and users of cooling towers and evaporative cooling equipment should take the necessary steps to prevent the risk of outbreaks, thus safeguarding the health and safety of their employees and the general public.

Maintaining good water quality is vital to the safe and efficient operation of cooling towers.
Alchem Industries can provide a specifically-designed water treatment package for your system, taking into account factors such as make-up water quality, the materials of construction of the cooling water system and operating patterns.

It is important to keep records of all water treatment, monitoring and cleaning and disinfection actions. All records must be kept up-to-date and be readily available for inspection by the Health and Safety authorities.

In 2013 the HSE published a new Code of Practice L-8 on the control of legionella bacteria in water systems. This was supplemented with the associated technical guidance  HSG274 part 1 specifically for cooling towers.
