  • Controlling Pharmaceutical Coating & Drying Process Emissions

    Capturing and destroying harmful emissions from pharmaceutical processes can be challenging. It’s not because the volatile organic compounds (VOCs) are difficult to destroy using catalytic or thermal techniques. It’s because their concentrations can be so high. These process streams raise safety concerns, both when they’re collected in vents and when they reach the final ...

  • Top 10 Valve Considerations for Pressure Management Zones/DMA’s

    For basic pressure management or more advanced modulating pressure management, water suppliers create a network of District Metered Areas (DMA’s) or smaller, more manageable pressure management zones.
