Best Swimming Pool Chlorine Alternatives Buying Guide
Before choosing the best swimming pool chlorine alternative you should consider following options:
1. UV (ultraviolet) disinfection: UV disinfection uses ultraviolet light to kill bacteria and viruses. UV disinfection is simple to install and maintain, and it is one of the least expensive disinfection methods.
Although UV disinfection has minimal operational costs, it has drawbacks. UV disinfection doesn’t effectively kill some bacteria, viruses and parasites. Therefore, it is most effective for treating water that has low levels of organic matter.
Also, UV light can degrade and may require replacement every five years or so. Finally, UV disinfection isn’t effective in cold weather, when the water temperature drops below 60 degrees F.
2. Ozone generation: Ozone is a powerful oxidizing agent that kills bacteria and viruses. Ozone is effective in cold water and can kill microorganisms that UV disinfection can’t kill, including Giardia, Cryptosporidium and Legionella.
However, ozone has disadvantages. First, ozone is unstable and can be poisonous if it escapes from the water treatment system. Second, ozone is corrosive and can damage equipment. Also, ozone may require special treatment and disposal of the by-products.
3. Alum, copper and silver ion generation: Copper, silver and aluminum ions kill bacteria and viruses. These disinfection methods are effective in cold water and can kill microorganisms that UV and ozone disinfection can’t kill.
Although alum, copper and silver ion generation has benefits, it also has drawbacks. First, these disinfection methods can be expensive to install and maintain. Second, they may require special treatment and disposal of the by-products.
4. Combined UV, ozone and alum, copper or silver ion generation: Combining these disinfection methods improves water quality and reduces the number of disinfection by-products. However, it increases operational costs because of the expense of installing and maintaining multiple disinfection methods.
5. Ultraviolet photolysis: Ultraviolet photolysis combines UV light with ozone for enhanced disinfection. This dual disinfection method is effective in cold water, and it reduces the number of disinfection by-products. However, it increases operational costs because of the expense of installing and maintaining multiple disinfection methods.
6. Advanced oxidation: Advanced oxidation uses a chemical oxidizer for disinfection. Advanced oxidation has high operational costs because of the expense of installing and maintaining multiple disinfection methods. Also, advanced oxidation may require special treatment and disposal of the by-products.
