Advances in Wastewater Treatment

Photo Chemical Machining (PCM) is a manufacturing process that plays a key role in the production of countless precision and decorative parts, such as circuitry components, heat sinks, optical attenuators. grids, meshes, hardware, jewelry, ornaments, and commemorative pieces. A wide variety of metals and alloys are common to the PCM industry. Federal, State, and local agencies regulate many ofthese metals and alloys, such as cadmium, chromium, copper, lead, nickel, silver, and zinc due to their qualitative characteristics.
