Pool Sanitation Systems – What We Recommend
Pool sanitation systems are how swimming pool water is disinfected or kept in a healthy and usable condition for swimming. Most pool sanitation systems are based around oxidising agents like chlorine that chemically render water borne pathogens, like germs, non-functional.
Historically, chlorine and chlorine generator systems like salt water chlorinators, have been used for sanitising pool water. Chlorine is widely used as a sanitation method for drinking water and treatment of wastewater etc. Chlorine is noxious and dangerous, so are hydrogen peroxide, bromide, silver and copper ion based ionisers, UV light systems etc. Fundamentally killing “Organics” in swimming pool water requires the use of dangerous chemicals and dangerous systems of sanitiser delivery.
Just as everything “Organic” or living isn’t necessarily advantageous to us, similarly, not all chemicals, however dangerous they may or may not be – are to be avoided.
The modern trend of demonising chemicals and eulogising “natural systems” is, intuitively, understandable. However, in practice, “natural” systems of management aren’t usable within modern swimming pools.
So called “fresh water pools” or natural pools are rarely practical. They are only possible with vast volumes of water, cold water temps and low bathing loads. Such conditions are rarely preferred for use in suburban households.
The small water volumes (common in space challenged backyards), high water temps (desired for year round use) and high bathing loads (the backyard pool being the hub of family life in summer), mean that proven and effective sanitation systems are best for active families.
Many of the new sanitation systems on the market, use buzzwords like mineral pools, freshwater and chemical free – these are terms dreamed up by the marketing departments and not the R&D departments. In choosing a sanitation system for your swimming pool, the most important consideration should be the efficacy of the system, notwithstanding real concerns of allergies etc.
A simple salt water chlorination system uses the most wide spread and effective sanitiser (chlorine), a cost effective and reliable method of sanitiser generation (electrolytic cell) as well as additional technology to monitor and regulate sanitiser output. Such “salt water chlorine generators”, have been around for over 20 years and are still the most widely used technology.
Chemists know water as being a “universal solvent as well as the preferred medium of chemical action”. I guess what this means is that, water innately acts as an agent of chemical action, so in owning a large body of water (swimming pool), you will need to manage the chemical reactions that take place within it – chemically. Hence the need to maintain the pool water chemistry of your pool.
