What factors affect the disinfection effect of ultraviolet sterilizer in water treatment?

In the swimming pool water circulation and filtration system - disinfection system, ozone disinfection and medium-pressure ultraviolet disinfection is commonly used in medium and large swimming pools disinfection, both in the process of disinfection, will effectively reduce and destroy the harmful bacteria and chemicals in the water, making the water purification effect more obvious.

Unlike the ozone disinfection method, medium pressure UV sterilizers are a physical disinfection technology. Globally, medium-pressure ultraviolet disinfection technology is widely recognized and applied in large-scale municipal drinking water treatment and bottled water, beverage and other industrial industries. UV disinfection technology has unique advantages and development space in terms of energy saving, consumption reduction, environmental protection, etc. It can be said that UV disinfection technology is already a mature water disinfection technology.

What factors affect the effectiveness of UV disinfection?

Factors affecting the disinfection effect of ultraviolet sterilizer are: irradiation intensity, irradiation time and penetration rate of ultraviolet light. Among them, the irradiation intensity is related to the lamp type and lamp aging coefficient; the irradiation time is related to the design of the reflector, water flow rate and water flow rate; the penetration rate is related to the water quality, microorganisms, organic and inorganic content, and the penetration rate is regarded as a criterion for evaluating the effect of ultraviolet disinfection.

D=I-S-T

D-Ultraviolet irradiation dose

I--Ultraviolet irradiation intensity

S--Ultraviolet irradiation time

T--Penetration rate

The penetration rate of UV sterilizers in swimming pool water treatment applications is affected by water suspensions, concentration and atmospheric temperature. According to the information, the ideal water turbidity should not exceed3NTUand the Water Quality Standards for Swimming PoolsCJ/T 244- -2016 The turbidity of the pool water should not be greater than the turbidity of the pool water.1NTU. Therefore, the UV sterilizer installed after the pool water filtration equipment, can completely achieve the purpose of killing bacteria, viruses and microorganisms.

Since UV disinfection does not change the chemical properties of water, it is the ideal choice for fish ponds, swimming pools, and spa pools as a disinfection method. Pool water has complex water quality components as well as features such as long-lasting disinfectant by-products. When using ultraviolet disinfection, priority should be given to medium-pressure ultraviolet lamp sterilizer with broad-spectrum disinfection.

Medium-pressure ultraviolet sterilizer does not produce other chemicals disinfectant disinfection produced by harmful by-products and bad smell, the pool water does not produce secondary pollution; pool facilities, water purification and treatment equipment, pipelines, etc. does not corrode; swimmers, water players will not produce stimulation, and has the function of decomposition of chloramines, therefore, in the disinfection of the pool water has been valued and applied.
