New updated report on swimming pool water quality and products used in swimming pools. To down-load the report click here or go to  www.afm.eu

If it not AFM its not activated or safe to use and this is why

AFM  crushed        glass There are many fine products used in the swimming pool industry and some which perhaps should not have seen the light of day. There are other products which can be potentially very damaging to public health and well being. One such product that is being investigated is UV irradiation. Medium pressure UV has the potential to increase the THM level just above the surface of the water. Considering that THM`s (mainly chloroform) is carcinogenic, we should be monitoring THM levels on a regular basis.  Dryden Aqua manufacture UV systems, but we stopped supplying to swimming pools 10 years ago because of this problem. Only now is the international community waking up to the health risk.

In other situations, some products may be fine on their own, but in combination with other products adverse side effects can develop, indeed some combinations are extremely dangerous and will prevent filtration systems or disinfection equipment from working. The report click here is an attempt to try and clarify the situation. There is no easy answer because of the international nature of the problem, but it should not be ignored just because it is not easy.

Suppliers and organizations in the swimming pool industry must have a Duty of Care, but all too often the focus is on cost,  and not on what is best for the client and the public.  At Dryden Aqua we are a technical company with a strong ethical as well as environmental policy. We manufacturer equipment and products such as AFM, we are also involved in R&D  that will eventually eliminate the need for most chemicals including chlorine in swimming pools. 

Dryden Aqua is now aligned with UK as well as Multi-National Organizations to provide a complete package of all equipment used for water treatment in swimming pools. By bringing all of the equipment, products and chemicals  under one roof, we are able to provide an integrated package that provides the best possible performance and cost benefits.  Our systems will normally cost more than a standard system, however there will be a return in the extra capital expenditure in under 5 years. The water quality will be stunning, the fabric of the building will be preserved, and  the public will enjoy a safe and healthy swimming experience.

Electrochlorination  click here  when Dryden Aqua DIN standard filters are operated properly with APF and NoPhos coagulation with zeta potential controllers, the chlorine demand of typical public pool will drop by 80% which allows small electrochlorinators 2 kg/day to be used for most 25m public pools. Cost is under 10k pounds UK. For larger systems 2 or more units may be used or our larger systems 5 kg and upwards.
NoPhos is a special coagulant that we use in public aquaria to remove phosphate from the water. Algae and bacteria require phosphate, if you eliminate phosphate you stop bacteria growth. For information leaflet pdf leaflet NoPhos
Disinfect Changing rooms click here  and eliminate odours and kill bacteria automatically with out using chemicals, for more information or go to www.OZONE.co.uk.
