cationic polyacrylamide emulsion  Preastol K 233 ,Zetag 9048 FS,Zetag 9248 FS replaced by Chinafloc EM C series

 

 

Preastol K 233 ,Zetag 9048 FS,Zetag 9248 FS are three cationic emulsion with different chagre ,they can be replaced by Chinafloc EM C series totally but with better performance.

 

Product Features

In addition to the advantages of solid polyacrylamide flocculant, polyacrylamide emulsion also has the characteristics of high charge density selectivity, fast dissolution speed, low energy consumption, easy storage and use. Compared with the traditional cationic polyacrylamide products, polyacrylamide emulsion is suitable for a wider range of pH value, higher charge stability, better flocculation effect, less dosage and a series of advantages. It is also suitable for the construction site without the installation of large dissolving device.

 

Polyacrylamide emulsion is widely used in all kinds of domestic sewage, chemical wastewater, oilfield sewage, sludge dewatering treatment, paper and other fields, polyacrylamide oil-in-water emulsion is also widely used in urban domestic sewage treatment, brewery, amylum factory, food processing plant and other sewage treatment. It is especially suitable for flocculation settlement of organic suspended matter in acidic or slightly acidic sewage. Paper industry used as retention aid filter, paper sewage treatment. In petroleum industry can be used as drilling emulsion coating agent or oil removal agent.

 

A precipitate is a chemical reaction that produces an insoluble substance in the solution of the reactant. It means precipitation removal under the action of gravity. Suspended substances in sewage can be a kind of physical process, simple and easy, good effect, is one of the important technologies of sewage treatment.

 

According to the nature of suspended substance, concentration and flocculation polyacrylamide coagulation performance, precipitation can be divided into: natural precipitation, flocculation precipitation, regional precipitation. The concentration of suspended particles in the domain precipitation is higher (more than 5000mg/L), and the sedimentation of particles is affected by other surrounding particles. The relative positions of particles remain unchanged, forming a whole common subsidence, and there is a clear mud-water interface between the clarified water and the sediment. Regional sedimentation occurred in both secondary sedimentation tank and sludge concentration tank.

 

Flocculation precipitation is the process of flocculation precipitation of particulate matter in water. After adding coagulant in water, the colloids and dispersed particles of suspended matter form flocculent under the interaction of molecular force, and they collide with each other and condense in the process of sedimentation, its size and mass continuously increase, and the sedimentation rate keeps increasing. The removal rate of suspended matter depends not only on the precipitation rate but also on the precipitation depth. The alum formed by adding coagulant to the surface water, the organic suspended matter in domestic sewage and the activated sludge will all flocculate and precipitate in the process of precipitation.

 

Precautions

1. Contact personnel shall wear protective equipment when using polyacrylamide emulsion, and skin contact parts shall be washed with clean water immediately.

2. The operation site should be cleaned in time to prevent slipping and falling.

Use the process editor to broadcast

1, before using cationic polyacrylamide emulsion products, should be shaken as well as possible;

2. During the dissolution operation, add this product while adding water. The dissolution concentration is recommended to be controlled at 1-5 ‰, and the ripening time is about 15-25 minutes.

3, 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 the groove of plastic, ceramic, stainless steel and other materials, stirring speed should not be too large, without heating.

5, the prepared dilute solution should not be long, 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 a time of 30-60 seconds or so), and then join this product, can not reverse the order, also can not be joined together.
