Is the swimming pool UV sterilizer easy to use? All you want to know is here!

2019-4-29 5,147

UV disinfection technology has been used in my country for many years, but its application in the swimming pool industry is not too long. Initially, ultraviolet light was used to remove and control the combined residual chlorine (chloramine) in indoor swimming pools, and to increase secondary disinfection. Nowadays, as people’s health concerns are increasing, and the maturity of the swimming pool market develops, the demand for UV disinfection equipment will become more and more extensive. Today will be a systematic discussion on the topic of using ultraviolet disinfection equipment in swimming pools.

Harm of chloramine


When it comes to swimming pool management, it will inevitably involve our protagonist-“chloramine”.


You are no stranger to chloramine. The pungent smell in swimming pools is mainly chloramine. And we often mistake it for too much chlorine. Although pool managers have tried many ways to control chloramine, the most effective way seems to be to dilute the indoor chloramine concentration through a large amount of air exchange. But the biggest problem with this is the low energy efficiency.


Therefore, in many modern facilities, it is not uncommon for chloramines to accumulate in the air, and its hazards are also multi-faceted:

 

 

Which is more suitable for medium pressure and low pressure


UV sterilizer installation location: pool raw water passes through hair/cotton filters, filters, ultraviolet rays, peripherals, and then returns to the pool


1. Low pressure: single band, disinfection-oriented, can remove monochloramine; low energy consumption, higher relative maintenance cost, larger installation location


2. Medium pressure: multi-band, disinfection, monochloramine; dichloramine and trichloramine can only be removed by MP, reducing maintenance and site requirements, but higher energy consumption

UV development direction:

  1. Adjust the output of UV intensity through PPM and total chloride probe
  2. Medium-pressure lamp power adjustment can reduce energy consumption
  3. Optimize bypass design to reduce maintenance impact
  4. Accurate grasp of the dosage requirements for different swimming pool environments.
  5. The configuration and selection should be based on the comprehensive factors such as flow rate, pool diameter, pool type (treatment pool, spa, competition pool, etc.), disinfection method (salt, bromine or chlorine).

  1. Endangering the respiratory health of users and staff
  2. It will accelerate the corrosion of the swimming pool and shorten the life cycle of the building. Especially stainless steel equipment (lifeguard racks, handrails, springboards, springboard railings, etc.) may cause discoloration and corrosion.
  3. In addition, the air treatment equipment in the swimming pool may be affected, and the free chloramines in the air will also corrode the air treatment equipment, increasing potential maintenance costs.
  4. Due to the production of chloramines, the use cost of chlorine preparations will be greatly increased

Advantages of UV removal of chloramines:

  1. Save time and energy of operators
  2. Save the chemical cost of chlorine preparations
  3. Medium-pressure UV will destroy all chloramines, monochloramines, dichloramines and trichloramines
  4. Ultraviolet rays can automatically and continuously reduce the chloramine compounds in the pool water, significantly reduce the exhaust and pollution of the swimming pool air, create a healthier and more comfortable indoor environment, and extend the service life of buildings and equipment.
  5. Ultraviolet rays have a wide range of applications: universal to all aquatic environments, including outdoor facilities such as activity pools, competition pools, spray systems, treatment pools, children’s pools, hydrotherapy pools and diving pools.
  6. Ultraviolet light has a significant killing effect against chlorine microorganisms, such as Cryptosporidium and Giardia.
  7. UV equipment helps to balance the chlorine load, so free chlorine can be kept at a low level.
  8. Due to the reduced use of chlorine, fewer chlorinated by-products are generated, fewer pH buffers are required, fewer chemicals are required for total pH adjustment, and the potential for generation of disinfection by-products is less likely.
