Why is Pool Sanitation Necessary?
Pool sanitation is necessary because of the presence of bacteria, viruses, fungi, protozoans, and algae. These microorganisms are usually too small to be seen by the naked eye, but can be detected through water testing. Most of these organisms are harmless to humans but some cause diseases and infections. If not eliminated, these “germs” can be transmitted to other swimmers. It is the duty of the pool owner to maintain proper pool sanitation and protect swimmers.
What is pool sanitizer?
Pool sanitation typically relies on a chemical sanitizer or a nonchemical pool sanitizer. Modern ultraviolet sytems are non-chemical. All sanitizers kill or inactivate the microorganisms present in swimming pool or spa water. Chlorine, the most popular sanitizer, may be added manually or generated on site through a salt water pool system. Chlorine free pools are now possible through the use of hydrogen peroxide.
How Can we Tell if our Water is Properly Sanitized?
For years, many pool owners and service professionals used pH and chlorine levels to determine water quality. Through research, we learned that pH and chlorine residual alone are a poor indicator of pool sanitation. There are too many other factors that can affect the sanitizing power of chlorine. In recent years, the Gold Standard of water quality measurement has become ORP, or oxidation reduction potential. Water treatment professionals and health officials use ORP as an effective measure of sanitizer activity in pools and spas. Residential pool owners are also beginning to use this more accurate test to measure water quality.
