Chlorine Gas Dosing System for Reliable Water Disinfection
A Waikato dairy factory needed a chlorine gas dosing system integrated into their existing water treatment infrastructure. This system ensures efficient water disinfection crucial for dairy operations, including cleaning, sanitation, providing potable drinking and process water.
Chlorine gas effectively eliminates harmful microorganisms, while leaving a residual disinfectant within the distribution network and water storage tanks. Its use over sodium hypochlorite reduces the amount of chlorates and perchlorates by-products generated in the water. This implementation aids the factory in maintaining hygiene standards, meeting regulatory requirements, and enhancing water treatment efficiency.
What We Did
Supplied and installed a new chlorine gas dosing system
FILTECย leveragedย the dairy factoryโs existing water treatment structure to integrate a newย chlorine gas dosing system.ย Theย chlorineย gasย dosing system supplied by FILTEC ensures the rapid and effective disinfection of the water supply at the dairy factory.
With carefully controlled dosage levels, the system efficiently combats potential hazards posed by harmful microorganisms, providingย a safe and sanitised water source for the various processes within the factory.ย
Maintained a Residual Disinfection of Chlorine in Water Supply
One of the key advantages of the chlorine gas dosing system is its ability to maintain a residual disinfection of chlorine in the water supply while minimising the amounts of chlorates and perchlorates that are formed as by-products of chlorine disinfection. This residual disinfection helps to continuously protect the water against any potential microbial contamination throughout the distribution system.
This ensures the water at the dairy remains safe and free from harmful pathogens and complies toย New Zealand Drinking Water Standards. The residual chlorine is also used to produce a catalytic reaction that removes dissolved iron and manganese from the water.ย
Provided Consistent Disinfection Levels and Reduced Maintenance
The integration of a chlorine gas dosing system into the dairy factory’s water treatment infrastructure has led to cost savings and reduced maintenance efforts. Unlike sodium hypochlorite, chlorine gas doesn’t degrade over time, resulting in fewer drum changes. Supplied by FILTEC, the system offers adjustable dosage control for consistent disinfection, accommodating varying water quality and flow rates.
Theย chlorine gas dosing systemย complies withย New Zealandย drinking water standards, ensuring that the water used in the dairy factoryย meets the necessary qualityย within theย standards forย publicย consumption and processing.
The Result
Strengthened Disinfection Practices and Improved Operational Efficiency
Theย chlorine gas dosing systemย retrofitย by FILTECย hasย been a transformative addition to the Waikato dairy factoryโs water treatment infrastructure.
It has strengthened water disinfection practices, achieved compliance with regulatory standards, improved operational efficiency, and offered long-term advantages for the factory. The successful implementation of this system serves as a model for other dairy factories seekingย reliable and sustainableย waterย disinfection solutionsย or iron and manganeseย precipitation methods.
