LYNXWATER cationic polyacrylamide are co-polymers of acrylamide with increasing proportions of cationic monomers. The cationic groups, which are thus introduced into the polymer, have positive charges in aqueous solution. Our cationic polyacrylamide is available in solid powder and emulsion forms.
Features: Various charge density, fast flocculation, compact flocs, low sludge moisture content.
Application: CPAM is widely used in sludge thickening, dewatering and municipal wastewater treatment, paper making and oil & gas process.

2.1.2 Dosage and Feeding of Dry PAM
Cationic polyacrylamide (CPAM) is synthesized by the polymerization of cationic monomers and acrylamide monomers. It is 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. Therefore, we should pay attention to investment in overtime to calculate in advance the proper dosage.
The solutions of LYNXWATER cationic polyacrylamide for chemical applications 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 LYNXWATER cationic polyelectrolyte and in order to achieve the best possible results, it is necessary to allow a “maturation” time of 30 minutes for the coagulation of water. 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.

2.1.3 Instructions
- 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 0℃and 30℃, 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 polyacrylamide 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 cationic polymer is a high molecular polymer with a 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?
Polyacrylamide cationic flocculant 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.
