Swimming pool disinfection is the process of keeping swimming pools clean and healthy. Proper sanitation is required to keep water clear and to avoid the spread of infectious waterborne diseases.
Let us understand the disinfection process of swimming pools.
Disease and contaminants in swimming pools
Swimming pool pollutants enter the pool from both outside sources and swimmers. Environmental contaminants that predominantly affect outdoor swimming pools, include windblown dirt and debris, incoming water from filthy sources, rain with microscopic algae spores, and bird droppings that may harbour disease-causing bacteria. Indoor pools are less vulnerable to toxins in the environment.
Contaminants introduced by swimmers can have a significant impact on the operation, of both indoor and outdoor swimming pools.Contaminants include microorganisms from infected swimmers and body oils such as sweat, cosmetics, suntan lotion, urine, saliva, and faeces. Furthermore, the interaction of disinfectants with pool water pollutants might result in a mixture of chloramines, and other disinfection by-products.
The problem with pool chemicals
Most pools and spas rely on chemicals to keep them clean. For more than 40 years, chlorine has been used to produce "safe pools."
However, it is becoming increasingly clear that during typical chemical disinfection, chlorine and other chemicals react with organic matter to produce hundreds of new chemicals, including disinfection by-products such as chloramines, which have been linked to eye redness and burning, skin irritation, asthma, allergies, and even cancer.
How is swimming pool water disinfected?
Ultraviolet (UV) light is increasingly being recognized as a safer, more cost-effective, and ecologically friendly alternative to traditional chlorination, and it has become the preferred choice for swimming pool treatment around the world.
The pool industry is transitioning to UV internationally, and one of the greatest disinfection systems on the market today is the UV disinfection system, along with the Commercial RO Plants.
Hygiene and maintenance
Good swimmer hygiene habits, such as showering before and after swimming and not allowing children with digestive illnesses to swim, can help to reduce contamination.Effective treatments are required to address contaminants in pool water. In fact, avoiding the introduction of pathogenic and non-pathogenic pool contaminants into swimming pools, is unachievable.
The first line of defence!
The first line of defence against contaminants large enough to be filtered is a well-maintained, properly running pool filtration and recirculation system. The removal of these filterable impurities as soon as possible, decreases the influence on the disinfection system, minimizing the development of chloramines, decreasing the formation of disinfection by-products, and optimizing sanitation efficacy.
Pool operators must maintain sufficient amounts of chlorine or UV to destroy microorganisms, and help prevent recreational water illnesses.
UV is widely acknowledged as the safer, more cost-effective treatment.
UV systems provide high-intensity germicidal light, which modifies or damages the DNA or RNA of organisms such as algae, bacteria, viruses, cysts, and protozoa.
The highly focused electromagnetic energy also eliminates organic matter, preventing the production of hazardous chlorine by-products known as chloramines, which are a common cause of eye burning and redness, skin irritation, asthma, and allergies.
