How does PAA affect the stability of water quality in water treatment?

PAA (polyacrylic acid) in water treatment on the stability of water quality is mainly reflected in the following aspects:

Scale inhibition: PAA can form stable complexes with calcium and magnesium ions in water, preventing them from forming insoluble salts with carbonate and sulfate, thus avoiding the formation of deposits on the surfaces of pipelines, heat exchangers and other equipment, and maintaining the stability of water quality.

Dispersing effect: PAA has good dispersing performance, which can disperse the tiny particles or suspended matter already formed in the water and prevent them from gathering into large particles, reducing the risk of deposition and scaling.

Stabilizes pH: PAA's acidic properties regulate the pH of the water, helping to maintain the pH balance in the water treatment system, which is important for preventing corrosion and biological growth.

Reduces microbial growth: By inhibiting microbial attachment and growth on pipe surfaces, PAA helps to reduce the formation of biofilms, which improves water quality stability.

Improve filtration performance: During water treatment, PAA can improve the filtration performance of filter media, reduce filtration resistance and extend filtration cycles.

Reduces corrosion: By controlling corrosive ions in water, PAA helps reduce corrosion of metal pipes and equipment and extends equipment life.

Improve water reusability: The use of PAA can improve the reusability of industrial water and reduce the need for fresh water, which is important for water conservation and sustainable development.

Environmentally friendly: PAA is a compound with good biodegradability and low environmental impact, and its use can reduce the negative impact on the environment.

In conclusion, PAA, through its chemical properties and mechanism of action, can effectively improve the stability of water quality in the water treatment system and reduce problems such as scale, corrosion and microbial growth, thus ensuring the normal operation of the water treatment system and the safety of water quality.
