induced gas flotation induced gas flotation (igf) is a water treatment process that clarifies wastewaters (or other waters) by the removal of suspended matter such as oil or solids. the removal is achieved by injecting gas bubbles into the water or wastewater in a flotation tank or basin. the small bubbles adhere to the suspended matter causing the suspended matter to float to the surface of the water where it mayplastics mcmastercarruse it to fabricate parts for hardtoreach places where adding lubricants would be difficult. this film is often used as a separator when heating parts in an oven. this polycarbonate has a staticdissipative coating that prevents electrostatic discharge from damaging sensitive electronic equipment.
mechanical pulping valmetctmp (chemithermomechanical pulp) the ctmp processes provide excellent bulk properties of paper at a high production capacity. the key subprocesses in ctmp pulping cover all the way from chip preparation, highconsistency refining, steam recovery, fractionation, treatment of long fiber fraction, bleaching and dewatering to pulp storage prior to papermaking process or drying and baling formineral processing metallurgy britannicamineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. it is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy.the primary operations are comminution and concentration, but there are other important operations
sonar sonar (sound navigation and ranging) is a technique that uses sound propagation (usually underwater, as in submarine navigation) to navigate, measure distances , communicate with or detect objects on or under the surface of the water, such as other vessels. two types of technology share the name "sonar" passive sonar is essentially listening for the sound made by vessels; active sonar is
