Cooling Tower Water Solutions


Water treatment is any process that improves the quality of water to make it appropriate for a specific end-use. The end use may be drinking, industrial water supply, irrigation, river flow maintenance, water recreation or many other uses, including being safely returned to the environment.

Cooling tower water treatment process

Optimal cooling tower water treatment process requires specialist knowledge. Following a comprehensive analysis of water components, energy and water consumption, along with operational aspects, Lubron provides a suitable cooling tower water treatment system. In the process, we adopt only the best available techniques to create a high quality, efficient and reliable solution.

The water treatment programme should be capable of controlling corrosion, scale formation and fouling to maintain the system’s cleanliness, as well as the elimination of all Legionella and microbiological problems. Appropriate water treatment may involve a range of chemical and physical techniques to control corrosion, scaling and fouling potential of the cooling water, and to control microbial growth in compliance with all current regulations. All of these parameters need to be monitored regularly by a trained and qualified engineer to ensure they remain effective. All equipment must be checked, serviced and modified as required, as well as agreed clean and disinfection of towers and systems.

Cooling tower water treatment system

Whether it is in open evaporative cooling systems, evaporative condensers, liquid coolers, direct adiabatic or hybrid cooling systems, central heating, hot water or steam boiler systems- microbiological contamination, corrosion, sludge and scale formation may occur, under the influence of various factors. This contamination leads to a decrease in the heat transfer and possibly even to loss of production. With the proper water treatment, Lubron minimises these risks and ensures maximum efficiency.

A cooling tower water treatment system is an arrangement of technologies that remove damaging impurities from your cooling tower feed water, circulation water, and/or blowdown. The specific configuration of your system will depend on several things, including quality of your feed water, volume of water being treated, type of cooling tower or system, bleed control and environmental compliance, which in this modern world is now a top priority when designing water treatment programmes.

Cooling water systems and their management must be considered as an influent to effluent system and this is the approach of Lubron. Our input ensures the highest compliance in water treatment including scale and corrosion control, microbiological and Legionella control. But this is in combination of assessing and controlling energy costs, water volumes, plant  and tower maintenance, the lifetime of all of the plant including dosage and control equipment, monitoring rigs, process costs and ultimately ensuring a green approach to always improving environmental impact and savings.

Capex and Opex

Lubron understands the importance of delivery aligned with capital expenditure allocation without compromising on quality and performance. That is why we always use the best available techniques in order to achieve an optimal balance between investment and operational costs. Additionally, we create a sustainable water treatment plant with minimum energy and water consumption levels.

Legionella control

In evaporative cooling systems, aerosols are formed, causing a risk of legionella infection. In compliance with the applicable legislation and regulations, sufficient measures must be taken in order to avoid these risks and proper water treatment plays an important role. Our specialists have extensive experience and provide a compliant solution for optimal design, as well as guidance for managing and maintaining the systems.

Overall Water Management Programme

In summary depending on the water quality requirements, a number of techniques can be applied for cooling water management, health and safety and efficiency:

  • Pre-treatment plant including water softener for cooling tower, Reverse Osmosis units, Filtration, UV technology
  • Dosage and control equipment along with local and remote monitoring
  • Recognised chemical programmes in compliance with current regulations HSG 274 parts 1,2 & 3
  • Sampling and testing of all water parameters including feed, treated water, cooling system water and where required discharge waters
  • Cleaning and disinfection programme of cooling towers and all associated water recirculation systems
  • Risk Assessments, method statements, all monitoring and control results, certification and clear management pathways for personnel involved in any area of responsibility

FAQ’S about cooling tower water treatment

Why do we add chemicals to a cooling tower or cooling system?

The recirculating water is the perfect environment to produce scale, sludge and microbiological activity including the production of Legionella Pneumophila. The correct management programme and application of cooling tower water treatment chemicals will control and eliminate these issues.

Why is the number of concentration cycles important in cooling towers and cooling systems?

Higher concentration cycles will reduce the volume of water used or bleed down the drain and hence water costs, discharge costs and the environmental impact should be considered at all times. However, high cycles enhance the need for the right chemical programme to be put in place, including cooling tower scale inhibitor and biocide dosage along with testing of water quality at all times.

Is legionella control really an issue?

Yes, it is a number one priority in cooling tower systems as they are the perfect environment in encouraging population growth of Legionella organisms. The transfer of these organisms in aerosols can be inhaled by anyone in their local environment. The complete chemical management and correct testing and cleaning programme is required at all times.

Who requires training in legionella management?

Any person who is involved in the operation and management of cooling towers and systems must receive training. This covers the engineer on the ground to the senior management team as required by all current Legionella Health and Safety legislation.
