Flocculant (Cationic Polyelectrolyte)for DAF System of emulsion cationic polyacrylamide
chinafloc EM4008 and Chinafloc EM5008 can meet the applications with good result.
Polyacrylamide emulsion not only has the advantages of solid polyacrylamide flocculant, but also has the characteristics of high charge density selectivity, fast dissolution, low energy consumption, easy storage and use, etc. Compared with traditional cationic polyacrylamide products, polyacrylamide emulsion is applicable to a wider range of pH values, higher charge stability, better flocculation effect, less drug use and a series of advantages. It is also suitable for construction sites without large dissolving devices.
Polyacrylamide emulsion is widely used in various domestic sewage, chemical wastewater, oilfield sewage, sludge dewatering treatment, papermaking and other fields, polyacrylamide water-in-oil emulsion is also widely used in urban sewage treatment, brewery, amyla plant, food processing plant and other sewage treatment. It is especially suitable for the flocculation settlement of organic suspended matter in acidic or slightly acidic sewage. It is used as retention and filtration aid in papermaking industry and treatment of papermaking sewage. In petroleum industry, it can be used as emulsion coating agent or oil removing agent for drilling.
Using the process
1, before using cationic polyacrylamide emulsion products, should be shaken as far as possible;
2. When dissolving, add water while adding this product. The dissolution concentration is recommended to be controlled at 1-5 ‰, and the curing time is about 15-25 minutes.
3, when conveying to avoid the use of centrifugal pump and other high shear rotor pump, the best use of screw pump, diaphragm pump and other low shear pump;
4, the dissolution operation should be carried out in plastic, ceramic, stainless steel and other materials of the tank, stirring speed should not be too large, without heating.
5, the prepared dilute solution should not be stored for a long time, it is best to dissolve with use;
6, polyacrylamide emulsion and inorganic coagulant compound use of wastewater treatment, should be added to the inorganic coagulant, to appear obvious alum (generally separated by about 30-60 seconds), then add this product, can not reverse the order, also can not be added together at the same time.
Precautions for polyacrylamide emulsion storage
1, at room temperature, in closed container storage period is generally 6 months, and pay attention to avoid light;
2, small bucket storage should pay attention to regular turning, shaking, to achieve full mixing, prevent stratification;
3. When storing in a large container, install a multi-leaf stirring that can be extended to the bottom of the container and open regularly. Or install a circulating pump and stir regularly to ensure full mixing and prevent delamination.
4, the best storage temperature is 50-80 °F (10-27 °C), the product can not be frozen, otherwise it will affect its performance.
5, if the product once frozen phenomenon, will be moved to a high temperature place, make it slowly thaw, before use to fully mix, and 100 mesh screen filter.
Polyacrylamide emulsion packaging and transportation:
1, 25KG plastic drum, 200KG plastic drum or ton drum packaging.
