Arpal Gulf LLC’s successful Aqua Division, in partnership with UK based Dryden Aqua – an experienced marine biology company specialising in water quality and sustainable treatment technologies – now provides a highly innovative range of water treatment products for public and private swimming pools across the UAE.
Led by one of Arpal’s most experienced in-house technicians and using ground-breaking filtration technology, the Aqua Division has been highly effective in providing safer, more environmentally beneficial and cost effective water treatment solutions.
The technology uses a unique long-lasting filtering system which has many advantages over traditional chlorine or sand based filtering systems, including no harmful reaction by-products such as trichloromine’s (THMs).
Safe and Clean Swimming
Whether you are a committed swimmer or a family looking for some pool-time fun in the UAE’s wonderful holiday weather, everyone has the right to know that the swimming pool being used is hygienically clean.
Responsible pool operators will adhere to strict standards to keep their pools safe and clean; but it is surprising to note that there are no uniform international standards in place for maintaining adequate pool hygiene.
The absence of an international regulatory framework for pool and spa safety, combined with the presence of incomplete national regulations in many countries, put bathers at risk especially vulnerable groups such as young children, the elderly, pregnant women and people with immunodeficiency disorders.
According to the Center for Disease Control (CDC), the average swimmer contributes at least 0.14 grams of fecal matter to pool water, usually within the first 15 minutes of entering. This can result in e.coli bacteria being present in the water.
There is a risk of recreational water illnesses (RWIs) being spread by swallowing contaminated water with the most common being diarrhea, but others include – cryptosporidiosis, giardiasis, leptospirosis, legionellosis, bacterial and viral gastroenteritis.
So you think the water is safe, but how do you know? It looks clean so it must be clean?
When entering the water, we add sweat, urine, invisible fecal matter, lotion and sunscreen to the soupy, invisible brew of chemicals and bacteria already present in the pool water. One in five Americans admit to urinating in the pool, according to the US based Water Quality and Health Council. As urine interferes with the chemically treated pool water, eating up the chlorine, there is less available to kill germs.
100 Years of Chlorine
All recreational water must conform to local regulations, with the presence of an active biocide to prevent horizontal contamination between bathers within a time frame of 30 seconds. This German DIN standard has been adopted by the Dubai Municipality.
The technologies used to keep swimming pools clean have hardly changed for the last 100 years or so. Chlorine remains the preferred disinfectant to ensure water is free of unhealthy bacteria.
Keeping chlorine at recommended levels is essential to maintain a healthy pool, but large quantities are not always needed to keep the water safe. Lowering the chlorine content improves the water and surface quality thus protecting people from intense chlorine odour, itchy eyes and skin. A strong chlorine odour from the pool often means there is a maintenance problem.
Chlorine, although an excellent disinfectant, reacts with organic and inorganic substances in the water to produce potentially harmful by products such as trichloramine which causes eye irritation and possible lung damage. Similarly, traditional sand filters are an ideal breeding ground for bacteria, viruses and other pathogens.
The Dryden Aqua Solution
Scottish based Dryden Aqua says:
“As marine biologists working on chlorinated systems for dolphins in captivity, we saw that many of these animals succumb to lung damage, pneumonia and neurological damage resulting from chlorine disinfection by-products. The average life-span of a dolphin in a system with a combined chlorine concentration above 0.2 mg/l is about 10 years. In their natural habitat, dolphins live for 50 years.”
Operators recognising the need for rigorous, effective pool and spa safety practices can benefit hugely from AFM® an innovative alternative filter media which replaces sand in all filtration applications. AFM® is manufactured from a specific glass type and processed to obtain the optimum particle size and shape. It is then activated to increase the surface area by 300 times over crushed glass or sand.
Currently, most pools will use sand as a filter media giving a 10-15 micron filtration to the water (a single hair is 70 microns). Arpal Aqua & AFM® can yield a micron level of filtration of 0.1 microns.
AFM® is certified under Regulation 31 in the UK and International NSF61. It is also in compliance with European Water Directive (98/83/EC) & (80/778/EEC).
