Technical specification NoPhos home | MSDS data sheetWhat is NoPhos NoPhos is prepared by Dryden Aqua from the rare earth element, the product has four properties with regards to water treatment; Phosphate precipitation Slows down or stops algae and bacterial growth by removing their food source Flocculation, NoPhos is an excellent flocculent, when used before AFM® solids down to 1 micron may be filtered from the water. The product works synergistically with AFM® Bio-Catalyst, when added to activated sludge systems, the NoPhos will create a large stable bacterial floc, which can enhance and stabilise nitrification and BOD reduction
Benefits from using NoPhos Aquaria systems; removes phosphates, reduces algae levels improves water clarity Swimming pools & Aquatic Parks; used at a higher level than aquaria, NoPhos will almost eliminate phosphate and make the water clearer. Also because phosphate is required as a trace nutrient for algae and bacteria, NoPhos will reduce or prevent bacterial growth. Combined chlorine and THM levels will also be reduced. The process takes around 2 to 3 months for full benefits to be realised Water & Wastewater treatment; flocculation of solids and phosphate control, best used before AFM® filtration, will remove solids down to 1 micron Activated sludge, generates large stable bacteria floc, enhances nitrification Lakes & Ponds; removes phosphates, controls algae blooms, makes the water clearer
Why use AFM® as opposed to sand ?Media bed filtration is a key element in phosphate removal systems. Sand filters act as an excellent support matrix for bacteria, especially bacteria such as Pseudomonas species that produce a extra cellular alginates. The alginates trap solids and promote the growth of more bacteria that eventually cause coagulation of the filter bed. However during the interim period, the organics trapped by the alginate are subjected to mineralisation and may release nitrogen and phosphates back into the product water. AFM® does not support bacteria, therefore there will be less organics held within the bed and less to no release of phosphate back into the product water.AFM® and NoPhos combined reactions, re phosphate removalAFM® (Active Filter Media) carries a surface -ve charge, when NoPhos is used in combination with AFM® filter media a high percentage of the catalyst not reacted with the phosphate will combine with the AFM® enhancing the surface active properties of AFM® . The NoPhos is then free to react with phosphate to form insoluble phosphate in the filter bed which is then removed on the next back-flush NoPhos + PO4-3 = NoPhos PO4 (s) 1kg of NoPhos will remove approximately 100g of Phosphate as PO4 -P ( or 300g of PO4) |
| Any NoPhos on the surface of AFM® filtration media will be available for the catalytic oxidation of organics in the presence of oxygen, hydrogen peroxide, ozone or chlorine. This technique can be used for the cracking or prescribed toxic chemicals in water and waste water treatment systems.. In clean water systems such as drinking water and Aquariums, the combination of AFM® and NoPhos will remove solids, phosphates and decolourise the water. The systems reduce the need or eliminate the requirement to use ozone, UV or advanced oxidation systems. |
