How to maximise the life of your pump tube

Practical information : APF® coagulant & flocculant dosage

APF® Coagulation & flocculation

Use the Stenner Floc-Dos pump to obtain a constant low flow rate and inject 0.5 to 1 ml of APF® / m3 of filtered water directly or just before the filter pump

Filter flow rate: 20 m3/h APF® dosage: 10 to 20 ml/h

For an efficient coagulation & flocculation, make sure to maintain a neutral pH and an alkalinity > 80 ppm. The addition of a ZPM between the pump and the filter can amplify the reaction and serve as an injection point.
