Dryden Aqua Daisy Filtration System for Overflow Pools

Dryden Daisy consists of three integrated steps:

Step 1. Filtration with the bio-resistant filter media AFM®:
AFM stands for Activated Filter Media, a revolutionary filter media made from green and brown container glass, developed by marine biologist Dr. Howard Dryden. AFM® exceeds the performance of quartz and glass sand by filtering at least twice as efficiently. The catalytic properties on the surface of AFM® make it fully bio-resistant, which means no biofilm is formed in the filter bed. This reduces the chlorine demand and therefore the formation of harmful volatile disinfection by products such as THM's, cyanogen chloride and trichloramine. Not only the chlorine smell but also the risk of getting infected by pathogens like legionella or cryptosporidium, is greatly reduced. The pool is healthier, especially for children, safer for the environment and more economical.
AFM® has been successfully used in over 500,000 public and private swimming pools worldwide.

Step 2. Best coagulation and flocculation with APF® and ZPM:
AFM Grade 1 will remove practicals down to 4 microns (at a filtration speed of 20 m/h). When AFM® is combined with a ZPM static mixer using APF®(All Poly Floc), the nominal filtration will go down to 0.1 microns and much of the dissolved organic matter will also be removed. Dissolved organics such as urea, creatine and amino acids are responsible for up to 80% of the chlorine demand.
Lower concentrations of organic matter mean lower chlorine demand and lower concentration of disinfection by-products (DBP's).

Step 3: Use the power of the sun with ACO®:
ACO® acts as a catalyst and chlorine stabiliser in outdoor pools. With ACO®, the natural power of the sun is significantly increased and chlorine is protected from photo oxidation by the sun.
