In order to better maintain the cleanliness of swimming pool water and create a pool with excellent water quality, more and more operators are adopting high-tech mechanical equipment to disinfect and sterilize the pool water. The earliest developed technology is to treat the pool water through ozone and ultraviolet radiation, followed by salt chlorine machines and chlorine free disinfection machines.
The ultraviolet sterilization and disinfection function of swimming pool specific ultraviolet disinfection equipment has long been applied in medical, industrial, agricultural, environmental protection and other fields to treat domestic water, fishery and aquaculture water, factory sewage, etc. In the application of sterilization and disinfection of swimming pool water, research by scholars from China Academy of Architectural Design has shown that "medium pressure ultraviolet sterilizers can generate full wavelength ultraviolet radiation, which not only has good disinfection effects, but also has the ability to degrade chemical chlorides (chloramines) and trihalomethanes in swimming pool water, effectively improving the water quality of swimming pools; and has the advantages of low energy consumption, low cost, no secondary pollution, and harmless to the environment. It is one of the ideal processes to replace traditional chlorine disinfection." The specific working principle of ultraviolet disinfection in swimming pool systems will be explained in detail in the following special report.
Due to the wide range of applications of ultraviolet sterilizers, if you are not familiar with the specific configuration requirements when purchasing equipment for swimming pools, it is recommended that you consult the manufacturer based on the size of the pool, or directly purchase the pool specific ultraviolet sterilizer that has been configured by the manufacturer. Shenzhen Kangche Water Purification Equipment Co., Ltd., which has been in the industry for more than ten years, divides its products into municipal water supply ultraviolet sterilizers, household ultraviolet sterilizers, sewage ultraviolet sterilizers, immersion ultraviolet sterilizers, etc. according to the specific application needs of customers, and also provides ultraviolet equipment accessories.
The pollutants in the swimming pool mainly include bacteria brought in by swimmers themselves, human secretions, algae growing in the pool, and dust in the air. Outdoor swimming pools are also affected by rainwater, dust, leaves, insects, and other debris. Also, due to the direct contact between the swimmer's body and the pool water, and the possibility of inhaling the pool water into their mouth, the pores of the human body will also exchange sweat and pool water in the water.
The specialized ultraviolet disinfection equipment for swimming pools should meet the following requirements:
1、 The equipment is simple, safe, reliable, and easy to operate.
2、 The measuring device of the swimming pool dedicated ultraviolet disinfection equipment is accurate, flexible and adjustable, and automatic recording should be set up when conditions permit.
3、 At least one backup set of chlorination machine should be set up.
1、 Strong bactericidal ability, does not pollute water quality, and has sustained bactericidal performance in water.
2、 The equipment is simple, reliable and safe to operate, and easy to manage.
3、 Low construction and maintenance costs.
When using chlorine disinfection method for swimming pool specific ultraviolet disinfection equipment, the following regulations should be followed:
1、 Disinfectants are liquid chlorine or sodium hypochlorite, and small specialized swimming pools can use chlorine tablets.
2、 The amount of chlorine added is determined by calculating the free residual chlorine in the pool water at a concentration of 0.4-0.6mg/L.
3、 Liquid chlorine should be added automatically using a vacuum method, and a device should be installed to ensure thorough mixing and contact between chlorine and pool water.
4、 Sodium hypochlorite should be added by gravity to the suction pipe of the circulating water pump.
Article 1.5: When using ozone or ultraviolet disinfection, chlorine disinfection should also be supplemented.
