  • Process gas mass flow controllers - An overview

    A mass How controller (MFC) is used 10 control the How of gases in a wide range of microelectronic processes. A well-designed MFC maintains a constant tlow within I percent of the full-scale flow, has a repeatability of 0.2 percent of full scale, and has a response time of 1 second to reach within 2 percent of the desired (command) flow, all of this is in response to any changes in command flow. ...

  • Skimming Oily Wastewater

    As large generators of oily wastewater tighten effluent controls, the U.S. Environmental Protection Agency (EPA) is targeting smaller generators. Some of the firms receiving their attention are smaller manufacturing plants, automotive garages, mobile equipment service shops and truck farms. Many of these firms do not have access to a sanitary sewer system that will accept oily wastewater. Because ...
