Why polyacrylamide is used for sludge dewatering

Cationic polyacrylamide Introduction: As the molecular chain with a positive charge and become an important part of the industrial sector materials and additives. In the sewage treatment as a flocculant for mining, metallurgy, textile, paper and other industries. Used in the oil industry for a variety of operations.
Cationic polyacrylamide Application:
Used in the oil industry for a variety of operations, such as drilling and development used to prevent slush hydration of clay shale clay stabilizer. Drilling and extraction of sewage treatment flotation flocculant, acidifier thickener, three oil recovery with water shuttler, drilling
And completion of the oil layer protection agent. In the paper industry can be used as retention aid, sizing machine and enhancer, greatly improved the performance of the paper, so that it has a larger market demand.
Cationic polyacrylamide production process: cationic polyacrylamide monomer → mixed → join the initiator copolymerization → granulation → drying → grinding → screening, packaging.
Cationic polyacrylamide Application: Can be used as tertiary oil flooding agent, water treatment agent, urban sewage flocculation and sludge dewatering agent, new beneficiation collector and used as soil and water humectant. All kinds of organic sludge dehydration (decanter centrifuge, belt filter).
Product Features:
Why polyacrylamide is used for sludge dewatering
This series of products flocculation effect is very strong, because it has:
1. Filter to promote the role;
2. thickening and other effects. In the waste treatment, sludge concentration dehydration, mineral processing, coal washing, paper and so on, to fully meet the requirements of various fields.
3. To clarify the role of purification;
4. Sedimentation promoting effect;
Features :
1. Cationic polyacrylamide use less, add a small amount of this series of products, you can get a great flocculation effect.
2. Solubility is good, in cold water can be completely dissolved.
3. The use of this series of products and inorganic flocculants (polyferric sulfate, poly aluminum chloride, iron salts, etc.), can show greater results.
Instructions :
1. Adjust the pH of the treated solution to give full effect (the optimum pH is selected by the test and the amount used in this series.)
2. When used, dubbed 0.1 - 0.3% concentration of aqueous solution, cationic polyacrylamide to use neutral non - salt - containing debris of water is appropriate.
3. Dissolve, this series of products evenly into the stirring of water, stirring speed control in the 100 - 300rpm. Appropriate heating (<60 ℃), can accelerate the dissolution.
