Water Treatment Chemicals For Cooling Towers
Protect your cooling system with advanced chemical treatments designed to prevent scale, corrosion, and biological fouling.
Well-maintained cooling towers help preserve the longevity and performance of your entire operation. Therefore, it’s essential to monitor the condition of your system and apply the right cooling tower chemicals; that’s precisely where B & V Chemicals can help.
Why Cooling Towers Need Chemical Treatment
Cooling towers, by the nature of their operation, are susceptible to scale, corrosion and microbial growth; the correct selection and application of cooling tower water treatment chemicals are an integral part of the strategy of maintaining safe and efficient water systems. HSG274 Part 1 guides the control of Legionella bacteria in evaporative cooling systems.
Cooling tower chemical treatments offer many benefits. Prevention of scale build-up, microbial growth, such as legionella bacteria, and prevention of system corrosion caused by oxidation and chemical reactions.
With regular, monitored application of effective cooling tower chemicals, you can rest assured that your water systems are working efficiently and in line with industry regulations. This will provide a reliable water cooling infrastructure that meets your evolving needs.
Key Chemicals Used in Cooling Tower Water Treatment
Scale Inhibitors
Scale inhibitors work by preventing the bui,ldup of scale-forming mineral deposits. They achieve this by either inhibiting the growth of existing scale crystals, preventing new ones from forming, or dispersing existing scale particles. This helps maintain the efficiency of the cooling tower and extends the life of the equipment.
Corrosion Inhibitors
Cooling towers are at risk from corrosion, which can weaken equipment and contaminate water if not treated correctly. Chemical corrosion inhibitors work by interfering with the electrochemical reactions that occur and cause metals to corrode. Corrosion inhibitors contain components to mitigate corrosion and help extend the lifespan of your equipment.
Biocides & Algaecides
Biocides and algaecides are chemicals used in water treatment to prevent microbial growth, such as algae, fungi, and bacteria such as Legionella. They include oxidising and non-oxidising treatments, which will help support and maintain clean and efficient water conditions.
Dispersants & Antifoaming Agents
Biofilm buildup within a system will greatly inhibit the heat transfer efficiency of the system as well as block pipework. A build-up of biofilm within a system will also encourage the growth of Legionella bacteria and may promote the formation of under-deposit corrosion. Bio-dispersants can be incorporated in the treatment regime for cooling towers in several ways, including within the formulations of some of our range of scale and corrosion inhibitors. Antifoam agents are usually kept on hand for the rare occasions that foaming occurs within a cooling system.
How to Choose the Best Water Treatment Chemicals
Selecting The Right Cooling Tower Chemicals For Your System
Legislation requires that cooling towers must prevent the proliferation of Legionella bacteria within these systems as a precaution against the outbreak of Legionnaires’ disease. It is therefore critical that the correct treatment regime is implemented and regular checks are carried out to ensure that conditions within the system are kept under control. When choosing the best chemical water treatment for your cooling tower, there are several factors to consider, such as:
- Water quality
- System metallurgy
- Manufacturer specifications
- Treatment control systems
- Regulatory compliance
- Cost-effectiveness
- Industry requirements
- Environmental impact
At B & V Chemicals, we’ll work with you to assess your current setup and introduce the most effective cleaning chemicals for your cooling tower.
