Solving Foam Control in High-Salt Corrosive Environments

In industrial water treatment systems (e.g., papermaking, chemical processing), high-salinity wastewater and extreme pH environments trigger persistent foam, reducing equipment efficiency and accelerating pipeline corrosion. Traditional defoamers fail at salinity >3% or harsh pH. For example, a paper mill experienced 50% more pump shutdowns and 30% lower dewatering efficiency due to foam accumulation.

Chemi Tech's silicone-polyether graft copolymer defoamer delivers triple breakthroughs:

Salt-Acid Resistance: Polyether chains enhance water solubility, while siloxane backbone resists corrosion at pH 1-14 and 10% salinity;

Rapid Penetration: Low-surface-tension droplets penetrate foam membranes in <5 seconds;

Long-Term Inhibition: Nano-dispersed particles adsorb at gas-liquid interfaces, suppressing foam for 72 hours.

Case Study: Chemical Park High-Salt Wastewater

A chemical plant (wastewater: 8% salinity, pH=12) used Chemi Tech's defoamer (0.08% dosage), achieving:

98.5% Foam Removal: Foam layer thickness reduced from 25cm to 2cm;

Equipment Protection: Pump maintenance intervals extended 3×, saving ¥2M/year;

Process Optimization: Water recycling efficiency reached 95%, freshwater use cut by 30%.

This solution is deployed in textile scouring wastewater lines, eliminating foam overflow at 90°C/pH=13.
