Polymaleic Acid (PMA) Applications

Polymaleic Acid (PMA) is used across multiple industrial water treatment applications:

  1. High-Temperature Boiler Treatment: Maintains scale inhibition efficacy at steam temperatures up to 300°C.
  2. Desalination & Flash Evaporators: Prevents severe calcium carbonate scaling in thermal desalination evaporators.
  3. Oilfield Injection Water: Prevents mineral scale in high-salinity oilfield formation water recovery.
  4. High-Hardness Cooling Towers: Operates effectively at high cycles of concentration and high alkalinity.

Polymaleic Acid (PMA) Dosage & Dosing Guidance

The required dosage of Polymaleic Acid (PMA) depends on feed water quality, operating temperature, system pressure, and total dissolved solids (TDS).

Typical Application Dosage Ranges

Application Area Typical Dosage Range*
High-Temperature Boilers 5–15 mg/L (ppm)
Thermal Desalination 1–5 mg/L (ppm)
Cooling Towers 2–10 mg/L (ppm)

*Indicative dosage ranges. Final dosage should be established through water analysis and technical evaluation.

Dosing Calculation Formula

Commercial Product Required (kg/day) = [Flow Rate (m³/hr) × Dosage (mg/L) × 24] ÷ [Active Fraction × 1000]
