Maintaining safe, clean water in industrial, commercial, and institutional facilities is essential to ensuring the health and longevity of water systems. From small internal pipework to large-scale industrial water networks, effective chlorination is key to preventing harmful pathogens, protecting equipment, and ensuring compliance with regulatory standards. This guide explores chlorination best practices, tailored to the varying needs of different water systems and applications.

Why Chlorination is Critical for Water Systems
Chlorination is one of the most widely used and effective methods for disinfecting water systems, providing a powerful defense against bacteria, viruses, and other microorganisms. Whether for commercial or industrial use, the quality of water is paramount—particularly when it is used for drinking, cooling systems, or in sensitive industrial processes.
Regular chlorination not only ensures water remains safe and free from pathogens like Legionella, but it also helps maintain the overall integrity of the water system by preventing the growth of biofilms and organic contaminants.
The Importance of Chlorination in Commercial and Industrial Water Systems
For commercial water systems, proper chlorination not only protects users but also preserves the longevity of the system by preventing organic buildup, reducing odours, and improving water clarity. In industrial settings, maintaining water quality is crucial for both health and operational efficiency, as contaminated water can damage equipment, impair cooling systems, or affect industrial processes.
Types of Water Systems and Chlorination Methods
Smaller water systems, such as those found in offices, schools, or small commercial properties, require periodic chlorination to maintain water safety, especially when systems are newly commissioned, repaired, or have been out of use for an extended period. Regular maintenance ensures that chlorine levels are kept within safe limits, and thorough flushing of the system is critical to removing any remaining chlorine before resuming regular use.
Best Practices for Small Systems:
Annual Chlorination: Chlorination should be conducted at least once a year, or after any significant repairs or extended downtime.
Measured Chlorine Application: The correct amount of chlorine must be calculated based on the total volume of the system to ensure effective disinfection.
Complete System Disinfection: All parts of the system, including seldom-used outlets, need to be disinfected to prevent the growth of bacteria in stagnant areas.
Thorough Flushing: After chlorination, flush the system fully to remove residual chlorine, ensuring the water is safe for normal use.
Large industrial water systems, such as cooling towers, extensive pipework, and water storage tanks, present more complex challenges. These systems often require continuous chlorination or shock treatments to maintain optimal water quality and prevent the formation of biofilm, which can impair system performance and harbor harmful bacteria.
In these large-scale operations, automated chlorine dosing systems are frequently employed to maintain consistent chlorine levels, while regular monitoring ensures that the system remains within safe and effective disinfection parameters.
Best Practices for Large Systems:
Continuous Chlorination: For more complex systems, continuous dosing may be necessary to prevent microbial growth and biofilm accumulation.
Regular Chlorine Monitoring: Consistent monitoring of chlorine levels throughout the system is essential to ensure proper disinfection.
Shock Chlorination for Maintenance: Shock chlorination is recommended during maintenance periods or after contamination, ensuring the system is thoroughly disinfected.
Commercial Chlorination Methods
Various chlorination methods can be employed depending on the type of water system and the level of water quality required. Here are the most common methods used in commercial and industrial water systems:
Shock chlorination involves applying a high concentration of chlorine to a water system to address contamination or prepare the system for commissioning or repairs. This method is particularly useful for resetting a system, eliminating biofilm, and ensuring that any residual contaminants are eradicated.
Continuous dosing is typically used for larger systems that require ongoing water quality management, such as cooling towers and industrial process water systems. In this method, an automated dosing pump maintains consistent chlorine levels to ensure continuous disinfection, reducing the need for frequent manual interventions.
After chlorination, some systems may require dechlorination to reduce chlorine levels to safe, acceptable limits before the water is returned to use. This is especially important in systems where excess chlorine could harm sensitive equipment or industrial processes.
Regulations and Compliance for Commercial Chlorination
Chlorination must be conducted in compliance with the relevant UK regulations, including the Water Supply (Water Quality) Regulations 2016 and the Health and Safety Executive’s (HSE) guidelines on controlling Legionella. Meeting these standards is critical for avoiding legal penalties, ensuring the safety of building occupants, and maintaining operational integrity.
Key Benefits of Commercial Chlorination
Enhanced Water Safety: Chlorination effectively eliminates harmful microorganisms, ensuring that water systems are safe for use in both industrial and commercial settings.
Regulatory Compliance: Proper chlorination helps companies meet stringent water quality regulations, protecting them from fines and operational disruptions.
Prevention of Biofilm: Regular chlorination reduces the buildup of organic materials that can lead to biofilm formation, which can impair system efficiency and foster bacteria.
Increased System Efficiency: Clean, well-maintained water systems improve the performance of industrial processes and prevent equipment degradation caused by contaminated water.
