Despite the popularity of UV and chlorine as swimming pool disinfectants, some pathogens are resistant to these chemicals. One such pathogen is the cryptosporidium, a protozoan that causes intestinal diseases. It is resistant to chlorine but is very sensitive to ultraviolet light. Hence, the combined use of UV and chlorine will kill virtually all microbial pathogens. Listed below are four swimming pool disinfection ideas for your next pool party.
Liquid sodium hypochlorite:
As the spring season turns to summer, daylight hour’s increase, and temperatures increase, making your swimming pool an ideal breeding ground for bacteria and other contaminants. In addition, daytime pool occupants sweat, use sunscreen, shed skin cells, and deposit dirt and algae into the water. Sodium hypochlorite for swimming pool disinfection is a natural and effective solution that won’t harm your swimming pool finish.
Sodium hypochlorite, also known as cal-hypo, is another alternative. This solid material is diluted in water with a stabilizer and can be added to a swimming pool in a floating container or inline feeder. Sodium hypochlorite, a slightly cheaper alternative, is effective only in hard water. If your pool has soft water, you will likely need a calcium supplement to raise the chlorine levels.
Calcium hypochlorite is a common swimming disinfectant that works by raising water’s calcium hardness. It also fights algae. However, you must remember to pre-dissolve the product before you use it. If you do not do this step, you may have a pool with an unpleasant smell and is not safe for swimming in.
Chloramines are commonly used in swimming pools to kill harmful bacteria and protozoans. Chlorine disinfectants can also kill other organic materials in water, including dirt, sweat, and urine. These chemicals can also form harmful byproducts known as chloramines. Chloramines are known to cause skin irritation, rashes, and other symptoms of illness. However, there are certain precautions you should take when using chlorine disinfectants in swimming pools.
Using UV radiation to disinfect a swimming pool is an excellent way to reduce the risk of waterborne diseases such as Cryptosporidium. This pathogen can survive for several weeks, even in heavily chlorinated water. UV can also kill other common pathogens like E. coli and Giardia, which can cause diarrhea and abdominal cramps. However, even UV systems cannot eliminate all chlorine, and pool managers should be cautious when considering this option.
