APF®- ALL POLY FLOC FOR WATER CLARIFICATION AND EQUIPMENT SANITATION
APF® is a multi-spectrum coagulant and flocculant that removes pollutants from solution and flocculates fine suspended solids, such as skin cells and bacteria, into large particles that are easily removed by AFM® (Activated Filter Media). No single flocculant or coagulant can remove everything from the water. APF® is a precise combination of 6 different electrolytes and polyelectrolytes to cover the widest possible range.
Dissolved constituents of water make up 80 % of the oxidation demand, and suspended solids around 20%. Everything that is filtered out does not need to be oxidised.
When the correct flocculation is used in combination with AFM®, oxidation demand is reduced and RedOx potential increases. In chlorinated systems, unwanted disinfection by-products are reduced by up to 80 %.
CORE BENEFITS
- For sanitary security, APF® is required to optimise removal of bacteria, parasites such as Cryptosporidium, Giardia and Mycobacterial parasites (Candida, Aspergillus etc).
- Economic and environmental Improved filtration reduces oxidation demand by up to 80 %. It also means there will be fewer disinfection by-products formed. Operating costs will be lower and there will be less of an impact on the environment.
- For chlorine-free treatment in biological systems APF® is an important aid in chlorine-free water treatment of aquatic mammal LSS in combination with AFM® filtration.

How to use APF®?
OPTIMISING CHLORINATED AND BIOLOGICAL LSS
How to use APF®?
APF® should be dosed into the water at a constant very slow flow rate. 0.5 - 1ml. of APF® is injected per m3 of water circulated through the filters. Only peristaltic pumps such as the Dryden Aqua flocculation pump should be used. For best results, APF® should be injected directly via a Dryden Aqua ZPM® static mixer, located between the pumps and the AFM® filters. The pH should be neutral, alkalinity should be greater than 30ppm.
Dosage Monitoring and Control.
Once commissioned, dosage can be monitored by weekly Aluminium analyses using Al test reagents in a standard spectrophotometer. Drinking water guidelines allow a maximum Al concentration of 0.2 mg/l. Optimal APF® flocculation requires 0.05 - 0.1ml per m3 of filtration turnover.
Performance of APF®?
AFM® filter media provides nominal filtration down to 5µ (at 20m/hr filtration velocity). When APF® is used, nominal filtration of 0.1µ is reached, so parasites such as Vibrio, Cryptosporidians, Giardia and Mycobacteria (Candida, Aspergillus) are removed from the water. APF® also contains NoPhos to remove phosphates from the water. If there are no dissolved phosphates, then bacteria and algae simply cannot grow. The improved filtration performance offered by APF® not only makes LSS safer and healthier, it can reduce chemical oxidant demand by up to 80 % and help protect our environment.
What is Coagulation?
Coagulation; is the process of dragging chemicals out of solution to form colloidal suspensions of small particles. In order to make coagulation work, APF® must be mixed instantly and aggressively with the water, this is why we designed the ZPM®. If a ZPM® is not used, the coagulation stage is missed, organics will remain in solution and APF® jumps to flocculation.
What is Flocculation?
Flocculation; is the process of bringing colloidal suspensions of small particles (organic detritus, bacteria and parasites) together to form larger flocs that can be easily removed by AFM®. APF® imparts a positive charge to particles that are then attracted to the negatively charge surface of AFM®. Flocculation takes several minutes and the particle floc is very fragile, so the water must not be subjected to aggressive agitation
FAQs ABOUT ALL POLY FLOC
APF® stands for All Poly Floc. It is a multi-spectrum coagulant and flocculant used to remove tiny particles, organic material, and other impurities from water during filtration.
APF® is commonly used in swimming pools, drinking water treatment, industrial water treatment, and wastewater recycling systems.
In many cases, yes. APF® can replace multiple traditional chemicals like separate coagulants, flocculants, and even reduce the need for chlorine.
APF® works best with advanced filters like AFM® (Activated Filter Media), but it can also be used with other sand or glass filters for better results.
Dosage depends on the type and volume of water being treated. It’s best to follow the product guidelines or consult a water treatment expert.
