AFM For The Swimming Pool Application

 

Use of AFM For The Swimming Pool Application –

AFM® is successfully working in over 100‘000 private and public swimming pools worldwide.

 

Where To Use AFM® In The Swimming Pool?

Every swimming pool has a pressure sand filter installed which normally has a sand as a media of different grades. AFM is used  to replace existing filter media in the PSF.

 

Why To Use AFM In The Swimming Pool?

AFM® reduces the biological risk from bacteria and parasites as well as the chemical risk from water and air just above the surface. The result is a safer pool for children, a healthier work place for staff in public pools and a greatly improved swimming experience for everyone.

 

Key Benefits At A Glance

  • Crystal clear water: AFM® filters at least 30 % more than silica or glass sand.
  • Lower consumption of chlorine: Everything filtered out doesn’t ́t need to be oxidized by chlorine. The better the filtration, the lower the chlorine demand.
  • No trichloramine – no chlorine smell: AFM® prevents growth of biofilm therefore eliminating trichloramine.
  • No biofilm – no Legionella: Biofilm is a slippery film of bacteria, that can provide a home for pathogens such as Legionella, Staphylococcus and (MRSA) Pseudomonas.
  • Chlorine-free systems:
 AFM® greatly reduces the oxidation demand of the water which makes it perfect for chlorine free systems.

 

Why Is Biofilm A Problem?

Silica sand is a good filtration media but it also makes a perfect home for growing bacteria. Bacteria like to stick themselves onto the sand by secreting an alginate jelly. The alginate forms a film that protects the bacteria from oxidation by chlo- rine. Some species of bacteria use carbonates to make organic matter, which doubles the chlorine demand after about six months.

Other bacteria produce an enzyme that converts urea into ammonia which then reacts with chlorine to form mono-, di- and trichloramine. Trichloramine is responsible for the chlorine smell; it stings your eyes and can cause lung damage and respiratory problems such as asthma.

AFM® is manufactured in a state-of-the-art hygienic factory designed by Dr. Howard Dryden to solve
all these problems. It contains metal oxide catalysts that dissociate oxygen and water to create a zone of high oxidation potential to prevent bacteria growing on the surface of AFM®. In addition, the huge activated surface area has a strong negative charge for the adsorption of sub-micron particles and dissolved organic molecules. This makes AFM® far superior to any other filtration media because AFM® is recharged by a simple back-wash.

The AFM® activation process increases the surface area available for adsorption to 300 times over 1‘000‘000 m2/m3. This means 300 times more surface area for the adsorption of dissolved organic pollutants. The huge surface area coupled with the magnetic attraction of the negative zeta potential makes AFM® the best filtration media for your pool.

 
Commercial benefits of use of AFM in swimming pool –

  • No lump formation in the PSF or no need to replaces the sand in the bed for the life of the filter.
  • Reduced chemical consumption by 20 to 30% at least.
  • Reduced operational, handling and man power cost.
  • Breakeven point of less than 1 year.
  • Cost of health can not be measured in terms of money.

AFM as in potable water treatment
AFM in pressure sand filter
AFM in SWRO plants

SWRO – Sea water reverse osmosis has found a great importance today as a technology for the reclamation of brackish water or sea water and making it potable enough for human consumption or industrial applications.  Read More…

AFM as pre-treatment to RO, DM & EDI plants

UF, RO membranes  & DM plant resins work best when they are new and clean. Fouling of the membranes by inorganic and organic contaminants as well as biofouling are some of the main issues effecting the performance and cost of running  water treatment systems.Read More…

AFM for Arsenic Removal

Arsenic is often found in borehole / tube wells and ground water at varying concentrations depending upon the geology of the ground. In India western states along with certain locations in the south have fairly high contamination of Arsenic in the ground water. IN certain cases Arsenic is also found in the waste water effluent of certain industries. Read More…

AFM for Iron & Manganese removal

Iron and manganese are often found in borehole / tube wells and ground water at varying concentrations depending upon the geology of the ground. Read More…

AFM for Chromium 6 removal

Chromium is occasionally found in ground water in trace amount from 1 to 10 ug/l however the occurrence of chromium is usually associated with pollution from industries such a leather tanning, wood preservation and textiles. Polluted ground water may have much higher concentrations. Read More…
