A BIOLOGICAL APPROACH: PREVENT RATHER THAN KILL!

DRYDEN DAISY BENEFITS
DAISY® (Dryden Aqua Integrated System) is an ecological and sustainable water treatment solution which prevents bacterial growth in your swimming pool. DAISY® can significantly lower the cost of water treatment, enhances water clarity, and provides a healthy swimming experience for all !
DAISY® consist of 3 integrated steps:
1. AFM: Improves filtration and eliminates all breeding ground on which bacteria can grow.
2. APF/ZPM: Removes dissolved pollutants and all vital nutrients for bacteria to stop their growth.
3. ACO: Amplifies the natural disinfection power of the sun and protects chlorine from photolysis.
STEP 1: FILTRATION WITH AFM®
No biofilm No pathogens
Thanks to its unique self-sterilizing surface, AFM® is the only filter media on the market to fully prevent bacterial growth in all sand filters. Impurities cannot stick on AFM® and are completely evacuated during backwash. The formation of biofilm - responsible for chlorine smells and channeling in the filter - is fully prevented.
1 micron filtration
With a certified 1 micron filtration rate, AFM® surpasses the performances of sand and other glass filter media. After only 24 hours, water becomes much clearer while chemicals consumption starts to reduce.
Sustainable filtration
AFM® offers a quick return of investment. It saves resources such as water, chlorine and energy thanks to slower and more efficient backwash. AFM® outlasts all other filter media and can be used in any sand filter without modifications. For the best results, we recommend a filtration velocity <30m/h and a backwash velocity >40m/h.
STEP 2: COAGULATION + FLOCCULATION WITH APF®
Improves filtration
APF® is a highly concentrated liquid product containing a precise combination of coagulants and flocculants for a wide spectrum of actions. APF® - when used with AFM® - is able to remove all particles down to 0.1 micron. Chemicals consumption is reduced to the lowest possible level.
Ensures optimal bathers' safety
APF® makes your pool safer and healthier by removing more polluants and organic substances from the water. The formation of harmful disinfection by-products - such as THMs - is significantly reduced. With APF®, more pathogens can be filtered out including chlorine resistant parasites such as Cryptosporidium and Giardia.
Prevents algae growth
APF® contains NoPhos, an ecofriendly coagulant which removes phosphates from the water to prevent algae growth in a natural and sustainable way. Dosage : Use a constant flow peristaltic pump and inject into a ZPM static mixer 0.3 to 1 ml of APF® / m3 of water circulated through the filter.
STEP 3: INCREASED OXIDATION WITH ACO®
Protects chlorine
Unlike cyanuric acid (CYA), ACO® filters UV light and protects chlorine without reducing its efficiency. ACO®avoids all problems with saturated water and unnecessary chlorine overdosage. Inorganic chlorine consumption is reduced by 20% to 40%. In salt pools: ACO® extends the lifetime of electrolysis cell.
Eliminates pollutants
ACO® is a photocatalyst that amplifies the natural disinfection power of the sun supporting the production of free radicals (OH.) through UV. Free radicals oxidize pollutants such as urea and chloramines. Chloramine concentration is reduced by up to 50% and turbidity by up to 40%, providing crystal clear and safe water.
Ecofriendly
Innovative and ecofriendly, ACO® is compatible with all types of treatments. It is a natural, non-hazardous product which does not form any harmful disinfection by-products. ACO® can be dosed automatically or manually : 1 liter / 100m3 / week. First dosage should always to be doubled.
