Foam accumulation in desalination under high-salt conditions disrupts liquid level control and reduces evaporation efficiency. Chemi Tech's specialized defoamer combines silicone and polyether-modified components to rapidly collapse foam via surface tension reduction. Key advantages include:
Exceptional Salt Resistance: Operates in brine up to 25% salinity. By leveraging Marangoni effect-driven convection, it prevents surface crystallization. For example, at Saudi Arabia’s Jubail 2 RO Plant (world’s largest membrane-based project, 1 million tons/day), it ensured stable water output with high-pressure membrane housings.
Enhanced Evaporation: Reduces water evaporation enthalpy by weakening hydrogen bonds under high-temperature alkaline conditions, achieving rates up to 3.47 kg·m2·h1 (under 1-sun irradiance) with 94.3% efficiency.
Industrial Adaptability: Compatible with RO, multi-stage flash, electrodialysis, and synergistic with scale inhibitors. Dosing only 0.001%–0.01%, it extended continuous operation by 30% in the Middle East Al Anbar Power Plant desalination system.
