Cooling Tower Water Treatment

Cooling Tower Water Treatment is an essential process for areas that typically involve Conditioning, Furnace Systems, Heat Treatment Processes and Refrigeration. These processes can be found in:

The safe and efficient running of a cooling tower system is reliant on good monitoring and management practices.


Advanced Water Technologies have over 24 years experience in managing both large and small scale cooling tower plant in a wide range of industries including heavy industry, food and dairy manufacturing, public sector systems and small private companies. We are aware of the importance of plant longevity and reliability and all our cooling tower management programmes are designed with this in mind.

Why do you need us to help with the control measures of your Cooling Tower?

Evaporative cooling towers and condensers are highly efficient cooling systems but if the water within them is not correctly treated then a number of issues such as corrosion, scaling and bio-fouling can occur.

Working together with a good water treatment company can control all of these things. It is essential to your company to implement them as a poorly maintained cooling tower is costly to you and dangerous to the surrounding area.

Advanced Water Technologies can implement control measures designed specifically for your individual requirements so you comply with the HSE Approved Code of Practice for cooling tower legionella control, ACoP L8.

The safe and efficient running of a cooling tower system is reliant on good monitoring and management practices. Whilst chemical water treatment is important, so too are the dosing equipment, general cooling tower condition and management practices. Without these in place a cooling tower system can soon be a hazard to those working in the surrounding area and even those remote from the cooling tower.

Advanced Water Technologies manufacture and blend our own cooling water treatment chemicals at our factory unit, thus allowing us to tailor treatment programmes to our client’s specific needs enabling cost effective and efficient solutions to be implemented. Additionally Advanced Water Technologies have developed a unique range of non chromate based corrosion inhibitors which have proven efficiency in preventing corrosion and are environmentally friendly, containing no heavy metals.

Cooling Tower water treatment can be found in many areas that typically involve Conditioning, Furnace Systems, Heat Treatment Processes and Refrigeration.

Cooling water should be treated constantly. Ideally, an automatic water treatment system should be used that continuously controls the quality of the circulating water.

Cooling Tower ManagementCooling Tower Management

The cooling system may consist of a cooling tower, evaporative condenser or other cooling element, the re-circulating pipework, the heat exchanger, pumps and ancillary items such as supply tanks and pre-treatment equipment. All of these items should be subject to the management and control system.


Cooling Tower Regulations and LegislationCooling Tower Regulations and Legislation

The Notification of Cooling Towers and Evaporative Condenser Regulations 1992 require the notification of wet cooling towers and evaporative condensers to local authorities in whose area the equipment is situated, regardless of whether the local authority or Health and Safety (Executive) is the enforcing authority.


Cooling Tower ContaminationCooling Tower Contamination

Open evaporative cooling towers use water to dissipate heat from a process usually via a heat exchanger. However, due to the wide range and various sources of incoming mains top up water to cooling systems a number of problems are quickly arising, these are shown as a matrix below and are all inter related if one factor is present they are all to greater or lesser extent.


Cooling Tower EfficiencyCooling Tower Efficiency

Fouled cooling towers and systems have been shown to reduce efficiency by 40% to 50%. This inefficiency increases operating costs which may not be in the budget. Most companies perform a risk management process to determine the frequency of Cooling Tower Cleaning but it is generally accepted practice to clean a cooling tower twice a year.


Cooling Tower Chemical TreatmentCooling Tower Chemical Treatment

Chemical water treatment is a vital part of cooling tower management to prevent both the build up of Legionella and to prolong the service life of components.


Cooling Tower Cleaning and DisinfectionCooling Tower Cleaning and Disinfection

Cooling Tower cleaning is essential to reduce the build up of accumulated nutrients; a primary cause of Legionella growth. Another problem is water that contains salts such as magnesium carbonate and calcium carbonate which are less soluble in hot water than they are in cold. These deposits, along with the scum that accumulates in cooling systems, can drastically reduce the efficiency, which could affect production processes and chiller operations.
