LYNXWATER amphoteric polyacrylamide are partially hydrolyzed polyacrylamide with high molecular weight. This amphoteric polyacrylamide is easily to remove both the positive and negative charged contents particles in a suspension solution. Features: Combined advantages of anionic and cationic types, strong anti-interference ability.
Application: Oilfield oily wastewater, complex industrial sewage, deep sludge dewatering.
2.4.1 Main Specifications of Amphoteric Polyacrylamide (PAM)

| Amphoteric PAM Powder | LW 9903 | Low | Medium | High |
2.4.2 Dosage and Feeding of Dry PAM
The solutions of LYNXWATER amphoteric polymer 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 amphoteric 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/, and the maximum operating concentration is 15g/l. For an optimum performance on specific applications on amphoteric flocculants, please consult with LYNXWATER team.
2.4.3 Instructions
- Flocculation Precipitation
Flocculation precipitation is the process of flocculation and precipitation of particles in water. When feeding flocculants or coagulant in water, the colloidal and dispersed particles of suspended particles forms flocs under the interaction of molecular force, and they collide and flocculate in the process of sedimentation. The volume and quality of sedimentation increase and sink speed increases. The removal rate of suspended matter depends not only on the velocity of precipitation, but also on the depth of precipitation.
- Chemical Feeding
Gravity feeding is to use the gravity to add the agent to the water suction pipe of the water pump or the water absorption well, and use the impeller of the pump to mix. Pressure feeding is to use water pump or water jet to put the chemicals into the original water pipe, which is suitable for putting the chemicals into the pressure water pipe, or we need to add them to the water purification structures with higher elevation and distance. Pump feeding is to use pump is to raise the liquid to the pressure tube in the solution pool. It has a direct use of the metering pump and the use of acid resistance to enhance the effect.
