Haviland's Antifoam H has been successfully applied in a wide variety of processing and wastewater applications including cleaner manufacturing, municipal wastewater treatment, and a multiple of industrial wastewater treatment processes, the company says. This product is effective over a wide range of pH and temperature. The product and other silicone defoamers are not suitable for water reuse.

Antifoam H may be applied near or in a continuously mixed water dispersion. For continuous processes, best results are obtained by feeding with a chemical metering pump. The typical effective dosage is in the 10 – 200 ppm range, however, maximum efficiency may be gained by bench testing.
