104 MAGNESIUM METAL1Water Filtration for Asbestos Fiber Removal
Two companies proposed producing magnesium from asbestos tailings in Quebec Canada One of the companies was building a pilot plant to test its process and if the process proves Magnesium is preferred to calcium carbide for desulfurization of iron and steel because calcium carbide produces acetylene in the presence of water e ABSTRACT This report was prepared so that concepts of water filtration for asbestos fiber removal could be presented in a manner that would explain results reported by other investigators to provide information for designers of water filtration plants and to give guidelines for the successful operation of filtration plants that are removing asbestos fibers from drinking water
