Alternatives to Pool Chemicals

Chemicals that help in keeping pools clean and transparent can also cause serious damage or injury to both human beings and the environment, if used improperly. Substituting hazardous chemicals with less toxic alternatives for cleaning the water in pools helps in reducing or eliminating our exposure of these chemicals. However, extreme care should be taken while choosing the right alternatives for the swimming pool. One must always check for the risks of the alternative to the employees, environment and for the damage to equipment and facilities.
Natural Alternatives to Pool Chemicals
Water when oxidized, produces ozone, which is a strong disinfectant. Ozone is one of the safest purifier that is extensively used in many drinking water systems. For oxidation, a generator is installed outside the pool that utilizes either ultraviolet light or electricity.
The process of gaining or losing electrons from an atom is called ionization. An ionic water purifier unleashes copper and silver to kill bacteria and stop algae growth. During the process, water molecules are converted into ions from the infusion of small amounts of these natural minerals. Copper and silver ions dispense from cartridges that are put into the filter of the pool or solar devices that float on the water. It eliminates the need to use pool chemicals and could turn out to be cheaper than chemical alternatives in the long run. It is also an automated system and therefore does not require to be tested for chemicals on a regular basis.
Salt water
Using common salt in swimming pools is not a new practice, though its use as a water purifier is only now starting to gain recognition. Here, table salt is to be used in very negligible proportions. When electrolyzed, it breaks down, resulting in a more natural, bacteria, virus and algae-free water. The process repeats itself and the chlorine present in the salt reconverts back to salt. Given the self-cleaning property of saltwater, it needs no other purifier or chemicals. Also, it is one of the most eco-friendly alternatives available.
Sonic waves
Particular sound waves have the ability to kill harmful algae and contaminants. A relatively new concept, sonic wave cleaning system works by placing a device under water that emits a complex system of sound waves resulting in breaking of algae cells.
Purifying Plants
Some plants can purify the pool water by creating a natural filter. They enrich the water with oxygen and supporting beneficial bacteria, which in turn feed on the potentially harmful organisms and deprive algae of nutrition. One can convert a traditional swimming pool to this natural alternative by landscaping around the pool.
