Products Feeding:

The solutions of SINOFLOC cationic polymers must be prepared in suitable plants equipped with dry powders feeding and dispersion units and with continuous and moderate agitation. The dissolution water must have a temperature included between 10°C and 40°C; For a correct use of SINOFLOC cationic polyelectrolyte and in order to achieve the best possible results, it is necessary to allow a “maturation” time of 60 minutes. When treating turbid water, the flocculants solution must be added to the water in a point of average turbulence, in order to achieve a thorough and homogeneous mixing without impairing the flock formation. Recommend operating concentration is 3g/l, and the maximum operating concentration is 15g/l.

What is the Main Characteristics of Sinofloc Cationic Polymer?
Our cationic polyacrylamide flocculants is amorphous, free-flowing powder, with Molecular Weight: 1 to 15 million.
What's the Main Application for Cationic Flocculants?
Cationic Flocculants is widely used in sludge thickening, dewatering and municipal wastewater treatment, paper making and oil & gas process.
What's the Procedure for Preparing Lab Flocculants Solution of Cationic Flocculants?
To make the 0.3% solution, weigh 1.200g of polyacrylamide powder accurately and add into 400ml of water in a 600ml beaker. The mixer motor must be capable of maintaining 800-1000 rpm to increase the solution viscosity for 30-35 minutes. The finished solution should be clear and homogeneous.
What are the Characters of Cationic Polyacrylamide?
Cationic polyacrylamide is mainly used in high speed centrifuge, belt filter press, plate frame filter machine and other special sewage machines. Cationic polyacrylamide has good effect in the formation of floc speed, extrusion resistance and shear, easier to peel and filter cloth and other characteristics. So it is with high dehydration rate, low moisture content of filter cake, use rarely, can be very good to help customers reduce the cost in use can be used, hydrochloric acid, sulfuric acid concentration in the liquid when used in separation and purification containing suspended substance. Because of its unique chemical and physical properties, it has made a wide use of the effect. Therefore, the actual use of this is widely applied to the sludge dewatering treatment of urban sewage treatment plants, breweries, food factories, tanneries, petrochemical plants, oil fields, metallurgy, chemical industry and cosmetics.  
What's the Flocculation Principle?
When polyacrylamide used for flocculation, the polyacrylamide molecular chain is fixed on the surface of different particles, and the particles of each particle form a polymer bridge to make the particles form aggregates and settle. And charge group particles on the polyacrylamide molecule could have surface adsorption effect.
Could Cationic Polyacrylamide be Used Alone in Water Treatment?
It mainly depends on the nature of water treated. If the impurities in the water particles larger, and with a certain charge, then the treatment performance of cationic polyacrylamide alone sometimes is good. If the impurities particles are small and non-charged, then it shall be added inorganic flocculants first and then add cationic polyacrylamide powder. An experiment is usually taken before answer this question. Without adding inorganic flocculants, add polyacrylamide directly to see if the impurities in the water flocculation can be flocculated. If the flocculation of water can clarify, then there is no need to add inorganic flocculants. If not then it should be used with inorganic flocculants.
Why is Polyacrylamide Used as Flocculants?
Polyacrylamide is most commonly used as flocculants, abbreviated as PAM. Flocculants is the linear polymer. Besides polyacrylamide solid aluminum sulfate, liquid aluminum sulfate, alum, polyaluminum chloride, ferric chloride, ferrous sulfates are also used as flocculants.
How to Storage Cationic Polyacrylamide Well?
First, select a well-ventilated and dry warehouse, and to reduce the time of sunlight as the sun exposure will make polyacrylamide molecular weight degradation. Moisturizing polyacrylamide is easily to agglomerate and hard to dissolve as an aqueous solution during dissolution. If in a solution case, after the polyacrylamide dissolved in aqueous solution not used up, the remaining polyacrylamide solution should be filled with a lid seal to prevent dust from entering. The storage time of cationic polyacrylamide is 48 hours, and for cationic polyacrylamide is generally not more than 12 hours. The solution becomes thinner when the polyacrylamide solution is stored for an extended period of time. 
What is the Difference between Polyacrylamide Emulsion and Powder?
The handling of polyacrylamide will be simpler than powders as in-line injection could be used with shorter dissolution time and no solubility problems. Powders are very stable during storage in physical setting and formation.
What are the Storage Principles for Handling Emulsions?
Emulsions must be stored indoor with temperature of 5oC to 30oC. In the storage and handling, the emulsion could not be contaminated with water. To keep the surface dry and ventilated. Before using after a long period, homogenizing is needed by gentle agitation with short periods. After a first opening and partial consumption the package must be closed tightly.

Tips for Using Polyacrylamide in Cold Temperature
Polyacrylamide as a polymer organic polymer, when dissolved, it will take a certain time to stir for the molecular chain of polyacrylamide to be fully opened. When the water temperature is too low, the dissolution rate of polyacrylamide will slow down. In winter, the mixing time of polyacrylamide is usually extended for half an hour for molecular chain to be fully expanded. If it is available, to heat the water to 20 to 30 degrees is also a good method to speed up dissolving. The water temperature cannot be too high, otherwise the high water temperature will accelerate the degradation of polyacrylamide, and affect the use effect.

How to Choose Polyacrylamide, Powder or Emulsion?

Unlike powder polyacrylamide, there is no drying process in the manufacturing process of emulsion polyacrylamide. Therefore, the molecular weight and water solubility of the emulsion polyacrylamide are higher than that of the same kind of powdery polyacrylamide.           

Oil - coated water emulsion is usually insoluble in water. The storage temperature of the emulsion is best between 0oCand 30oC, and the storage time of the emulsion is 12 months. The temperature of the emulsion is lower than that of water. The frozen emulsion can be continued after thawing. The greatest advantage of powder is that it is convenient for transportation and storage for a long time, and there is at least two years.

How to Avoid Polyacrylamide Agglomeration?

Polyacrylamide is a high molecular polymer with large molecular weight. When dissolved, it will first expand and then slowly dissolve. If the amount of polyacrylamide added to the water oversized, the surface of polyacrylamide first contacts with the water, then it starts to swell, then the surface area increases which will result to the part that does not touch the water is wrapped up. Some insoluble polyacrylamide groups are formed. It is suggested that in dissolving process, mix the water slowly and evenly, and then add polyacrylamide into the water, which reduces the probability of the cluster.

Advantage of Cationic Polyacrylamide in Sludge Dewatering?       

Cationic polyacrylamide has been more and more applied to sludge dewatering in various industries because of its good flocculation and dewatering effect. The ionic degree and dosage of cationic polyacrylamide can affect the effect of the sludge dewatering. The polyacrylamide is a synthetic cationic polymerization flocculants and so mainly related to chain length and the charge of the dewatering performance of polyacrylamide excessive dosage, the positive charge on the ion polyacrylamide adsorption, due to electrostatic repulsion, it will reduce the sludge settling performance, we should pay attention to investment in overtime to calculate in advance the proper dosage. The sludge is negatively charged, and the polymer polyacrylamide product with positive groups is added. The sludge colloid is destabilized by compressing the sludge electric double layer, charge neutralization, adsorption bridging and net sweep and capture, solid-liquid separation and gravity precipitation. After years of time, it has been proved that the cationic polyacrylamide has an unparalleled advantage over other ionic polyacrylamide products in the field of sludge dewatering.
