Dryden Aqua APF (Public Pool) 20kg
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%.
