Automatic Flocculant Chemical Polymer Dosing System Equipment in Waste Water Treatment Plant

The automatic dosing machine is widely used in the waste water treatment, it can mix the compounds continuously and effectively, so the reactive polymer solution appears. These main components of the machine: Polymer feed machine (including material hopper), Dry powder infiltration device, Tank, Level controller, Mixer, Dosage water inlet pipe, Electric control panel.

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

Advantages

■ The mixing system is optimized, which leads to more sufficient dissolution and lower energy consumption;

■ The solution concentration can be regulated by the quantity of intake water and the dosage of dry powder, which makes it much more adaptable;

■ More auxiliary functions can meet different users’ demands.
