SWIMMING CRYSTAL CLEAR
It can be a minefield for operators looking to select the right element for disinfecting and reducing organic loading of swimming pool water at their facility. Karen Maxwell talks to experts in water treatment about some of the options available

treated and disinfected. In the ‘old days’ virtually all commer-
O
cial swimming pools would have had a manually operated gas chlorine system for disinfection with pH controlled by the addition of soda ash/sodium bicarbonate and aluminium sulphate flocculants – often dosed by hand. How things have changed. With the introduction of relatively in-
expensive automatic control systems, sodium hypochlorite, calcium hypochlorite, ultra violet (UV), PAC flocculants and pH correction – using either CO2, hydrochloric acid or sodium bisulphate – are all now at the forefront of modern pool treatment systems. Chemical treatment today comes in several forms – from bulk,
tank and mixer and UV to, more recently, automatic calcium hypochlorite feeder systems. The need for chemical dosing to be simpler with health and
safety in mind, has led to several feeder systems being de- veloped which utilise calcium hypochlorite, and are widely accepted. The quality of calcium hypochlorite varies enormously and consideration should be given to the product’s chlorine, moisture (hydrated or anhydrous) and insoluble content, to establish value, safety and purity. JAK developed the FlowTab (calcium hypochlorite tablet dos-
ing system) several years ago. FlowTab has evolved over the years but we still have units in industry working from those early days. An automatic preparation system suitable for both municipal and potable water, it provides a constant strength solution, requires little maintenance and is compatible with all automatic control. Today, choosing products and treatment techniques can be
Water treatment methods should account for health and safety, environmental influences and cost effectiveness
confusing to the buyer and can become an expensive decision if made incorrectly. Deciding on the best treatment methods must take into account several factors – including environmental in- fluences, heath and safety and especially in today’s climate, cost effectiveness. A challenging task for even the most experienced pool operator where impartial advice may need to be sought.
