What is osmosis and reverse osmosis - Answers
Reverse osmosis is used for water purification, such as in a water treatment plant.
Reverse osmosis (RO) has become a common home water treatment method for drinking water that might be contaminated. The reverse osmosis process requires a driving force to push the fluid, such as

High cationic polyacrylamide flocculant
FHD PAM-1109 Cationic Flocculants acts as fixing agent for fillers, small fibers and sizing agents. It improves the retention rate of small fibers and fillers, reduces waste, concentration of white water consumption of pulp, improves paper ash, reduces pollution emissions, but also improves the paper drainage capacity of the wire end of the paper machine.

- Can cationic polyacrylamide be used in oilfield wastewater treatment?
- Author to whom correspondence should be addressed. Cationic polyacrylamide (CPAM) solid particle is one of the most commonly used organic polymer flocculants in oilfield wastewater treatment, but it poses some problems, such as a slow dissolution rate and an easy formation into a “fish-eye” in the process of diluting into aqueous solution.
- What type of polyacrylamide is used in oil industry?
- The polyacrylamide use can be anionic, cationic, or nonionic with various ratios of the comonomers used in the case of the anionic and cationic polymers. The anionic polyacrylamides in the oil field industry are designated by the generic name of partially hydrolyzed polyacrylamide (PHPA), although they are in actuality copolymers .
- What is a high molecular weight nonionic polyacrylamide?
- High-molecular-weight nonionic polyacrylamides are routinely used in the mineral processing industries as thickeners and flocculants , , . 34.2.5. Polyacrylamide product forms The product types for polyacrylamides are solutions, liquids (emulsion or dispersion), and dry powders.
- What is organic polymer flocculant cationic polyacrylamide (CPAM)?
- The organic polymer flocculant cationic polyacrylamide (CPAM) has the characteristics of a low additive amount, good turbidity removal and water purification effect, and high COD removal efficiency, and it has become the most commonly used polymer flocculant in the oilfield wastewater treatment process [ 11, 12, 13, 14, 15 ].
