Functions and Characteristics of antiscalants:

The action mechanism of antiscalants mainly includes three parts: chelation, dispersion and lattice distortion. High-efficiency reverse osmosis antiscalants can prevent membrane scaling, increase water production and quality, and reduce system operating costs.

The functional characteristics of reverse osmosis high-efficiency scale inhibitor include:

1. No need to add additional acid, effectively preventing acidic substances from corroding equipment.
2. Stable chelating effect can prevent iron, manganese and other metal ions from forming fouling on the membrane tube.
3. Applicable to various membrane tube materials.
4. The dosage of dosing is small, which saves the cost of dosing and can achieve economical scale inhibition control.
5. It has strong anti-scaling ability and is suitable for various water qualities. It can reduce the cleaning of the membrane and extend the service life of the membrane.
6. The efficacy and stability of this agent are far superior to those of sodium hexametaphosphate or pure polymer scale inhibitors.

Chelation: refers to a cyclic structure complex formed by a central ion and two or more coordination atoms of a multidentate ligand that meets certain conditions. Chelation can generate stable chelates, prevent the contact between scale-forming cations and scale-forming anions, and reduce the probability of scale formation.

Dispersion: Dispersion can prevent the mutual contact and agglomeration between scale-forming particles and prevent the growth of scale. The relative molecular weight of the dispersant is closely related to the dispersion performance. An efficient dispersant can stabilize the presence of scale-forming particles.

Lattice distortion effect: When the system hardness and alkalinity are high, the effect of the scale inhibitor is not enough to completely prevent the precipitation of scale-forming substances. At this time, the lattice distortion effect can prevent the scale-forming particles from being arranged on a regular lattice lattice. The generated dirt is easily washed away by water flow.
