SPN OCT 2010 AllergyFree
“Domestic and commercial swimming pool owners and managers face a choice of standard chlorine based products or a growing range of chemical free products, some of which are considered to offer a similar standard of water quality”
to agree test protocol for alternatives to chlorine. Without such formal tests, alternatives are unlikely to be widely accepted.
The OECD criteria includes: “The full-scale trials should be conducted by an independent agency accredited by a recognised accrediting authority. Results should be analysed and reported to the regulator without intervention by the applicant. The aim of the field test is to demonstrate the efficacy of the swimming pool or spa pool disinfectant or disinfection process under actual use conditions”.
Scientists have shown that outdoor pools are just as or more risky than indoor ones because harmful vapours remain at the pool surface and do not drift away. Children also tend to spend more time in outdoor pools and they are more likely to swallow chlorinated water or ingest vapours containing chemicals that attack the cellular barriers protecting the lung from allergens.
In the meantime, a number of options are still available for pool owners and managers having to face the public with allergy concerns. The Aligator Swimming Pool Water Purification System is a product available to swimming pools
which makes a point of stressing its benefits to allergy sufferers.
Aligator sales growth in 2010 has been to existing pool users who have finally had enough of skin rashes, asthma, red eyes, itchy skin all caused by a reaction to chemicals used in the swimming pool chlorine, bromine and salt. The growth in 2010 of sales in the specialist trade has been remarkable with established residential pool users moving away from traditional chlorine swimming pools. The Aligator Ionisation System will reduce chemical usage by up to 80% and the company claims pool users are now looking for an alternative that will be friendlier to allergy sufferers. The company has testimonials from pool users saying how delighted they are with the performance of the Aligator and that the children have no further problems.
The natural elements of silver, copper and zinc in the system reduce the chlorine related skin rashes, sore eyes, asthma and bleached hair. Aquafinesse, a water additive that is environmentally-friendly, works by breaking down and removing harsh chemicals in the water. According to Sally Koob the product can help

Aquafinesse is an environmentally- friendly water additive that works by eradicating the biofilm that can protect bacteria
people who were previously unable to use their hot tub or pool, and some customers have reported a positive effect on skin conditions such as dermatitis and eczema. The system works by eradicating the biofilm that can protect bacteria, leaving them unable to grow and multiply, and in addition, it softens the water by eliminating calcium and scale build-up within the tub’s working parts.
Another popular alternative is PoolSan, a chlorine-free water additive that is hypoallergenic and non-corrosive, it is described as a saturated complex ionic aqueous solution containing copper, silver, zinc, aluminium, gold, manganese, nitrogen and iron, a combination which eliminates the need for chlorine, algaecides and flocculants. These ions bring about a change in the enzyme processes of algae and bacteria, breaking down their DNA structure and cell walls. “PoolSan is documented as effective, with several years of independent trialling supporting its performance in public pools,” adds Celina Brown, Managing Director of PoolSan Direct, the company that supplies the product to the hotel and leisure industry. “Our corporate clients have made the decision that using it is a better option than traditional chemical treatments. It meets the strict requirements for keeping pools clean and enables ethically responsible companies to minimise their carbon footprint and environmental impact.” Two high density pools – one from a high profile swim school, the other a five star London hotel – have recently been keen to praise the benefits of moving from a chlorine system to PoolSan. Both viewed it from a consumers perspective. The five star Landmark Hotel and Spa in Marylebone converted its pool to PoolSan after being aware of concerns from its guests about strong smells and eye problems after swimming. They specifically went looking for a low or non- chlorine alternative.

Chief Engineer Paul Moore said: “After very careful consideration and investigation we decided to change to PoolSan as part of our commitment to the environment and our Carbon Reduction Pledge. We were very pleasantly surprised with the ease of the changeover and the fact that we didn’t
