Secondary water supply

Secondary water supply refers to a water supply method that uses water storage facilities (such as reservoirs and elevated water tanks) and pressure-boosting equipment (such as pumps) to store and pressurize water from the municipal network before delivering it to users in high-rise buildings where the municipal water network pressure is insufficient for direct water supply. As the final link in the urban water supply system, the water quality of secondary water supply is directly related to the drinking water health of residents.

Water Quality Risks in Secondary Water Supply Systems:

·Microbial Contamination Risk: Water remains in reservoirs or tanks for extended periods. If the tanks are not cleaned and disinfected promptly or are not properly sealed, they can easily lead to the growth of microorganisms such as bacteria, viruses, and algae, resulting in secondary water contamination.

·Residual Chlorine Decay: Municipal tap water typically contains a certain amount of residual chlorine to inhibit microbial growth in the pipe network. However, in secondary water supply systems, residual chlorine decays or even disappears completely due to factors such as storage, temperature fluctuations, and exposure to air, reducing its ability to inhibit microbial growth.

Ultraviolet Disinfection for Secondary Water Supply:

·Broad-Spectrum and Highly Effective

·Fast and Instantaneous

No Chemical Additives or Byproducts:

·Safe and Environmentally Friendly

·Easy to Operate

For high-level domestic water tanks: The disinfector is usually installed on the tank's outlet pipe.

For low-level domestic water tanks with variable-frequency pumps: The disinfector should be installed on the pump's suction pipe.

How does the UV disinfection process work with residual chlorine to ensure water quality safety：

UV irradiation accelerates the decomposition of residual chlorine (both free and combined chlorine) in water. When the UV dose is below 40 mJ/cm², it has little effect on chlorine decay. However, when the dose exceeds 40 mJ/cm² (which is generally higher than the dose required for effective disinfection), it significantly accelerates chlorine decay. Therefore, during operation, the UV disinfection equipment for secondary water supply should be linked to the residual chlorine level. When the residual chlorine level is normal, the UV disinfection dose should be maintained at 16 mJ/cm² as a safety measure. When the residual chlorine level is low, the UV disinfection equipment should switch to disinfection mode and adjust the dose to 40 mJ/cm².

The customer value of intelligent and refined UV disinfection in secondary water supply pump rooms:

·Intelligent monitoring system: Integrated online sensors monitor key operating parameters in real time, including UV lamps, quartz tube contamination, water quality parameters (UVT254), residual chlorine concentration (if a combined process is used), and process flow rate, providing a basis for dose control.

·Intelligent control and early warning: automatic dosage adjustment to ensure a constant effective UV dose, intelligent cleaning control, fault early warning and diagnosis, lamp life management, and remote management platform.
