In what areas can PESA be used?

PESA is an environmentally friendly, biodegradable water treatment agent known for its excellent scale inhibition, corrosion resistance, and dispersing properties. Here are its key application areas:

• Function: Inhibits scale formation (CaCO?, CaSO?, BaSO?) and disperses suspended particles.

• Advantage: Works effectively in high-hardness, high-alkalinity water.

• Dosage: Typically 5–20 mg/L.

• Prevents: Calcium phosphate and silicate scales in high-temperature boilers.

• Compatibility: Can be used with oxygen scavengers (e.g., hydrazine) in steam systems.

• Role: Reduces membrane fouling by preventing silica and carbonate scaling.

• Benefit: More biodegradable than traditional phosphonates (e.g., HEDP).

• Prevents: Barium sulfate (BaSO?) and strontium sulfate (SrSO?) scales in offshore/onshore wells.

• Environmentally Preferred: Low toxicity compared to aminopolycarboxylates (e.g., EDTA).

• Dispersant: Prevents mineral particle agglomeration in slurry pipelines.

• Replaces: Phosphates in eco-friendly detergents (complies with EU Ecolabel).

• Function: Softens water, enhances surfactant performance, and reduces scaling in washing machines.

• Controls: Calcium-based deposits in papermaking processes.

• Benefit: Improves paper quality and reduces downtime for equipment cleaning.

• Prevents: Dye agglomeration and inorganic deposits (e.g., Ca2?-dye complexes).

• Result: Improves color uniformity and reduces fabric defects.

? Biodegradable (OECD 301B certified)
? Non-toxic (no phosphorus/nitrogen, eco-friendly)
? Broad pH tolerance (effective at pH 5–12)
? Compatible with other water treatment agents (e.g., HEDP, PAA)

PESA is versatile for water treatment, oilfields, detergents, and industrial processes where eco-friendly scale inhibition is needed. For optimal use:

• Dosage: Adjust based on water hardness (typically 5–50 mg/L).

• Storage: Keep in sealed containers (avoid moisture for solid form).
