Description                                          

Prefloc 200 is a high-effective flocculating agent in the form of white granular or powder, composing of cationic monomer (DM, DMC, CPF, DMDAAC, DMAEMA, etc.) and cationic acrylic acid derivate.

Product features                                       

Prefloc 200 is used mainly for waste water purification, as well as for thickening and dewatering of municipal and industrial sewage sludges (centrifuges, screen belt pres-ses, chamber filter presses). The product is specially suitable for applications where the formed flocs are subject to high shear forces.

The mode of action of cationic PRAESTOL products is based essentially on ion exchange between the electrical charges along the polymer chain present in aqueous solution and the surface charges on the suspended solid particles. The particle surfaces are destabilized, thus bringing about coagulation or flocculation.

Packaging                                            

50 lbs / 100 lbs

Storage                                              

Store in dry, closed containers and protected from moisture.

Instructions                                           

Prefloc 200 is used as a dilute solution (approx. 0.1 %) . For preparation of stock solutions (approx. 0.5 %) the original product is added to water with uniform stirring. After a dissolving period of approx. 60 minutes (at a temperature of ³ 15 °C), the solution is mature and is thus ready for use. Owing to the very variable properties of the sludges to be dewatered, the required addition quantities for a particular application can only be determined by carrying out laboratory tests and industrial trials.

Experience has shown that in mechanical sludge dewatering the quantities required in order to achieve a high machine throughput and discharge water free of settleable materials is between 2 and 6 kg polymer per ton of dry solids in the sludge. When used as a sedimentation accelerator or clarifying agent (in static sedimentation processes), only a few grams of polymer per cubic metre of slurry to be clarified are required.

Safety Operation                                        

For safety reasons, when handling the product, the users should:

1) prevent dust development in case of dry product;

2) avoid contact with the eyes;

3) avoid extended contact with the skin;

4) rinse off the product after handling/touching.
