Introduction

The flocculant is often called polymer or poly-electrolyte.Flocculant poly-electrolyte must be prepared from a powder polymer or a fluid concentrated polymer.Polymer is a product that must be well mixed with water to prevent clot formation. After mixing with water a certain maturation time is necessary to "unfold" the polymer chain.Flocculant needs to "mature" about 30 to 60 minutes before it can be dosed.Matured polymer is a sticky liquid.For larger installations we recommend automatic polymer dosing systems for both powder and liquid polymer applications.An automatic polymer dosing systems consists mostly of three compartments with a dosing screw and a powder storage.In the first area the powder is mixed with water. The ratio water powder can be set-up perfectly.The second area is a maturation tank with stirrer .From the third area the matured polymer is pumped into the flocculator. A level probe mounted in an acrylic holder controls the make-up station.The dosing screw at the bottom of the powder storage is provided with a heating element to prevent condensation.In a polymer make up station of liquid polymer, the entire powderbuffer and dosing screw is replaced by a polymer dosing pump.
