It measured piquancy, or "spiciness", of various chili peppers. It is now standardized as the Scoville scale. In 1922, Scoville won the Ebert prize from the American
Heat exchanger and anti-scale chemicals with periodic lab testing. Plate and frame heat exchangers can be disassembled and cleaned periodically. Tubular heat exchangers can be cleaned by such methods as acid cleaning, sandblasting, high-pressure water jet, bullet cleaning, or drill rods. In large-scale cooling water systems for heat exchangers, water treatment such as purification, addition of chemicals, and testing, is used to minimize fouling of the heat exchange equipment. Other water treatment is also used in steam systems for power plants, etc. to minimize fouling and corrosion of the heat exchange and other equipment. A variety of companies have started using water
