DRYDEN AQUA 1. No grounds Thanks to our bio-resistant filter material AFM®, bacteria have no grounds for development. DA-SY = DRYDEN AQUA INTEGRATED SYSTEM Biologically instead of chemically 2. No food With perfected coagulation, flocculation and AFM® filtration, we deprive bacteria of their food and stop them from growing. INTEGRATED SYSTEM Traditional water treatment tries to prevent the spread of pathogens by using even more or stronger disinfectants. However, the spread of pathogens is a biological problem and therefore needs biological solutions: Instead of using even more or stronger disinfectants, our partner (Dryden Aqua) and we are designing a swimming pool system where pathogens cannot spread in the first place: prevention instead of killing! 3. Less chlorine, fewer disinfection by-products (DBPs): DA-SY® filters the maximum amount of substances to reduce chlorine requirements to the absolute minimum. Less chlorine also means fewer hazardous disinfection by-products (DBPs) can form. DA-SY® consists of three Filtration with AFM® Coagulation and flocculation with APF® and ZPM Catalytic oxidation with ACO® Scan QR code and find out more about the principle in our video. Water treatment Step 1: Filtration with AFM® Step 2: Optimum coagulation and flocculation with APF® and ZPM Step 3: Increased oxidation with ACO® AFM® stands for Activated Filter Material; it is a revolutionary filter material made from green glass and has been developed by Dr Howard Dryden. AFM® can filter 30–50% more organic substances from pool water than quartz or glass sand. AFM® also has more catalytic and oxidising properties to protect it from bacterial colonisation. Using AFM®, no biofilm can form in the filter bed, meaning—no harmful trichloramine, no smell of chlorine, lower chlorine consumption and virtually no pathogens such as legionella. AFM® produces healthy air and crystal-clear water. AFM® can achieve a nominal filter fineness of 4μm at a filtration speed of 20m/h. Using additional optimised coagulation and flocculation from APF® (All Poly Floc) and ZPM (Zeta Potential Mixer), you will undercut your nominal filter sharpness of 0.1μm since ZPM in particular generates a turbulent environment, improving the mixing of chemicals with swimming pool water. This will also filter a large amount of dissolved substances. They make up approx. 80% of your chlorine requirements. Certain pathogens and biofilm-protected bacteria colonies are enormously chlorine-resistant. ACO® is used as an oxidation catalyst and a chlorine stabiliser in open-air swimming pools, significantly increasing the sun’s natural disinfection properties and protecting chlorine from photo-oxidation. AFM® is successfully used worldwide in more than 100.000 public and private swimming pools.
