ACN/PoolSan Chlorine Free Pool Treatment Solution
“PoolSan” is a saturated acidic complex ionic aqueous solution containing copper, silver, zinc, aluminium and gold. The microscopic action of these natural mineral ions with the algae and bacteria are twofold. First, the algae and bacteria in the water are destroyed through a change in their enzyme processes as the ions break down their DNA structures and cell walls. Secondly, all these charged particles floc together so they can be trapped by a filter. The ions maintain a stable “PoolSan” residual in the water until they are used up by this process.
Typically a swimming pool with a volume of 50000 litres of water only needs to be dosed with one litre of PoolSan every 4 weeks and 1kg of PoolSan regenerator every week when the pool is in constant use or one kg every 4 weeks when the pool is not in constant use. The pH needs to be tested using the PoolSan Test strips and maintained at between 7.0 and 7.6 with 7.0-7.4 being the desired target. This can be done as and when necessary using the pH+ and pH- powders in the PoolSan complete pool care kit. The PoolSan solution is dosed by pouring half the dosage amount directly into the filter intake and pouring the other half of the dosage amount evenly around the pool. The PoolSan Regenerator is dosed by scattering the powder over the pool with two thirds being scattered over the deep end while the filter is running. The PoolSan Regenerator then needs to be left to dissolve for 10 minutes before bathing can resume.
The residual level of PoolSan is to be monitored by testing the water for copper content, using the PoolSan test strips. The target level is 0.4-0.8mg/l of copper. It should be noted that the UK and EU maximum allowable limit for copper in drinking water is 2.0mg/l, so your pool water would be well within this limit.
The advantages and desired effect of this pool treatment solution will be to improve the quality of the swimming pool water and drastically reduce the exposure of swimmers and lifeguards to chlorine and its irritating and harmful effects such as asthmatic conditions.
PoolSan Regenerator
The active ingredient in this non-chlorine shock product is potassium monopersulphate, also known as permonosulphate. Like chlorine, permonosulphate is an oxidiser that will destroy organic contaminants such as ammonia and other bather waste in swimming pools and spas. However, permonosulphate compounds do not kill or disinfect they simply control organics and combined chlorine, helping assure that the sanitiser can do its job as a disinfectant. Permonosulphates oxidise by using the element from which oxidation derives its name - oxygen. Oxygen is a pure form of oxidiser. Unlike with super chlorination which is used to disinfect and destroy organic matter (bather waste), where problems such as odours, eye and skin irritation occur -- Permonosulphates are effective in preventing these problems because they do not contain chlorine, but rather oxidise waste through the use of oxygen, they do not go through the various stages of chloramine formation to achieve breakpoint. Instead, they react directly with the ammonia to produce chloride and nitrogen (where chlorine is present in the water). Permonosulphates are particularly effective in increasing the efficacy of the PoolSan copper / silver disinfection system where the following occurs: Potassium monopersulphate has an oxidation potential high enough to maintain silver ions in a high oxidation state even to Ag3+ (Zsoldos and Kowalski, 1970). In a similar way, copper is oxidised to Cu3+. This is important for the removal of ammonia from pool water by the following suggested mechanism: Oxidation S2O8 (2-) + 2Cu (2+) ---> 2Cu(3+) + 2SO4(2-) From this one can see that the sanitising properties of the copper and silver ions are also considerably enhanced by the presence of potassium monopersulphate in the water. Organic matter is oxidised but no unpleasant compounds are formed. Potassium monopersulphate poses no risk to health on the ingestion of pool water, as its final reaction products consist of simple sulphates and oxygen.(Zsoldos et.al., 1970).
No matter how little of the non-chlorine shock you add, at least some of the organic contaminants will be destroyed, and no additional chloramines will be formed. This overcomes one major drawback of super chlorination. And if you overdose with a non-chlorine shock by adding more than is required, no extended waiting period is needed before swimming can be resumed. Although bathers should not be present when any chemical is added to the water, swimming can be resumed after the permonosulphate has had a few minutes to dissipate. In fact, the excess chemical will remain in the water, ready to destroy any contaminants that may enter the pool from bather waste and other sources. Permonosulphates are 100-percent soluble and will not leave a residue or bleach vinyl liners or swimming suits. Permonosulphates, are generally added at the rate of 1 kg per 50,000 litres (20grams per 1000 litres) on a weekly basis when the pool is in constant use and once per month when not in use. Potassium monopersulphate can be added to pool water day or night, and swimming can resume after a short waiting period to allow for adequate mixing and dispersion throughout the pool. No mixing is required—potassium monopersulphate is completely soluble in water and dissolves quickly. Potassium monopersulphate can be added manually or as a strong (10%) solution Broadcast monopersulphate shock slowly and uniformly over the surface of the water, adding about two-thirds of the total dose over the deep end. Apply the potassium monopersulphate with the filter running to ensure complete distribution. If the potassium monopersulphate is pre-dissolved in water as a 10% solution and this solution is fed into the intake sufficient mixing will take place to eliminate the need for bathers to evacuate the pool while dosing. For spas; Potassium monopersulphate should be added to spa water after every use, at a dose of about 30 to 40 grams per 1000 litres, to immediately oxidize and eliminate organic contaminants introduced by bathers. Permonosulphates effectively control the formation of chloramines, which cause odours, reduce disinfection and cause eye and skin irritation. Permonosulphates cause an acidic condition to occur i.e. they have a low pH of about 2.3 to 3, so steps may need to be taken to counteract the acidic condition that may be caused by using them. Permonosulphates do not add to the calcium or other undesirable solids or Cyanuric acid in the water. Also, no special handling is required. Permonosulphates are also safer to store and handle than chlorine products, because they will not burn or release chlorine gas.
As with any oxidiser, its duration in the pool depends on several factors:
• The organic loading on the pool such as leaves, number of persons using the pool, chemicals added such as citrates, oxalates, polyelectrolyte pool clarifiers, quaternary ammonium algaecides, etc. • Rainfall - when the excess water is run off to maintain the correct level of water in the pool, the active components of the system are lost. • Backwashing of sand filters, or diatomaceous earth filters results in the loss of sanitiser from the pool. • Use of reducing agents for pool cleaning such as metabisulphites, sulphonic acids etc.
PoolSan Regenerator provides many benefits.
• It will not produce chloramines or generate irritating chloramines odours • It promotes maximum PoolSan sanitizer efficiency by oxidizing and eliminating contaminant waste • It restores sparkle and clarity • It is gentle on pool surfaces—dissolves quickly and completely and will not bleach or fade vinyl liners or painted surfaces • It will not raise calcium hardness or increase cyanuric acid stabilizer levels • It is easy to use—simply broadcast uniformly over pool water surface, with filter running, to ensure complete distribution. • It fits easily into most water treatment programs for all types of pools and spas and provides sufficient oxidation to enhance sanitiser efficiencies and produce clear, sparkling water.
