What Are Chlorine Dosing Systems?
Chlorine dosing systems are specialised equipment designed to add precise amounts of chlorine to water supplies. These systems are crucial for:
- Eliminating harmful microorganisms
- Providing ongoing protection against recontamination
- Ensuring compliance with UK water quality regulations
Chlorine is most effective at lower pH levels, making it a highly efficient disinfectant. The primary forms of chlorine used in water treatment are chlorine gas, calcium hypochlorite, and sodium hypochlorite, each with specific applications and advantages.
How Chlorine Dosing Systems Work
Chlorine dosing is a widely used method for disinfecting water. While other methods like ultraviolet (UV) treatment and ozonation are effective, chlorination is unique in providing a residual effect that prevents pathogen regrowth.
Municipal water providers rely on measuring the “chlorine residual” – the amount of chlorine remaining in the water after it reaches its destination – as proof of safety. Typical residual goals range from 0.2 to 1 mg/L.
Beyond disinfection, chlorine helps oxidize iron, manganese, and hydrogen sulfide, aids in color reduction, and supports processes like sedimentation and filtration.
Types of Chlorine Dosing Systems
In the UK, three primary types of chlorine dosing systems are used to ensure water safety:
These pumps deliver liquid chlorine (usually sodium hypochlorite) directly into the water supply. They are versatile and commonly used for smaller-scale applications.
Advantages: Precise dosing control, ease of installation, and compatibility with various water treatment processes.
Gas chlorination involves injecting chlorine gas into the water. It is effective for larger systems and municipal water treatment plants.
Advantages: Efficient disinfection, long-lasting residual effect, and suitability for high-capacity water treatment.
Solid tablets, such as calcium hypochlorite, dissolve gradually, releasing chlorine into the water.
Advantages: Simplicity, low maintenance, and portability.
Mobile Chlorination Units & Dosing Trailers
We specialise in mobile chlorination units and dosing trailers, offering targeted chlorination services efficiently across the UK.
- Mobile Chlorination Units: Ideal for emergency disinfection, pipeline commissioning, or temporary water treatment.
- Dosing Trailers: Equipped with all necessary components, including dosing pumps, storage tanks, and safety features, these trailers are versatile and adaptable to various scenarios.
Key Components of Chlorine Dosing Systems
Dosing Pump or Feeder Mechanism: Precisely delivers the chlorine compound.
Chlorine Storage Tank or Container: Holds the chlorine solution.
Injection Point: The point where chlorine enters the water stream.
Monitoring and Control Equipment: Ensures accurate dosing and safety.
Safety Equipment: Includes leak detection systems and proper ventilation.
Our team ensures that all components meet the highest standards of quality and safety. Whether it’s a mobile unit, dosing trailer, or a larger system, we are committed to maintaining water quality across the UK.
Regulatory Compliance
We prioritise compliance with UK regulations to ensure safe water treatment. Key regulations we adhere to include:
These regulations set strict standards for various substances, organisms, and water properties to maintain water safety. Compliance is essential for protecting public health.
The DWI oversees drinking water quality in England and Wales, ensuring water is wholesome and free from contaminants. We follow DWI recommendations to maintain high-quality water standards.
WRAS approval certifies that our plumbing products and materials comply with water fittings regulations, demonstrating our commitment to water safety and consumer trust. WRAS-approved systems prevent contamination and promote efficient water use.
Applications of Chlorine Dosing Systems
Chlorine dosing systems play a vital role in various settings:
Chlorine effectively disinfects water at treatment plants, ensuring it is safe for distribution by targeting free-floating bacteria and pathogens.
For wells, boreholes, or other private sources, chlorine dosing maintains water quality, preventing microbial growth and ensuring safe consumption.
Chlorine is essential for pool water disinfection, keeping pools free from harmful microorganisms.
Industries use chlorine dosing to treat process water, cooling systems, and boilers, preventing scale buildup and controlling bacterial growth.
During emergencies, such as contamination events, chlorine dosing quickly disinfects water, safeguarding public health.
