water treatment dispersant is a chemical used in water treatment processes to disperse, stabilize and suspend solid particles in solutions. The ingredients usually include the following categories:
1. Anionic Surfactant: anionic Surfactant are hydrophilic organic molecules that usually contain long carbon chains and polar functional groups. They form micelle structure in water, through the interaction of hydrophobic and electrostatic repulsion, the solid particle surface adsorption and encapsulation, and make it dispersed in water.
2. Non-ionic Surfactant: non-ionic Surfactant are also widely used in water treatment. Their molecular structure contains no ions, usually oxygen, nitrogen and other polar groups. Non-ionic Surfactant can disperse solid particles by forming hydrogen bonds on their surfaces.
3. Polymer compounds: polymer compounds are one of the common ingredients in water treatment dispersants. They can be natural polymers, such as starch and lignin, or synthetic polymers, such as Polyacrylamide. Polymers disperse and stabilize solid particles by forming physical or chemical adsorption on their surfaces.
4. Buffers and acid-base regulators: in order to stabilize the performance of dispersants and pH, water treatment dispersants usually contain buffers and acid-base regulators. They can control the ph of the solution to adapt to different water quality and process conditions.
It should be noted that the specific water treatment dispersant composition may vary depending on the product type, manufacturer’s manufacturing process, and application requirements. In order to ensure the stability and performance of the water treatment system, suitable dispersants should be selected according to the actual conditions.
