真空/鼓风机

每个市政和效用都面临着能源成本上升的现实。In 2010, the Town of Billerica, MA, which is located 22 miles northwest of Boston with a population of just under 40,000 residents, engaged Process Energy Services and Woodard & Curran to conduct an energy evaluation of the Town’s Wastewater Treatment Facility (WWTF) and pump station systems sponsored by National Grid. The objective of the evaluation was to provide an overview of each facility system to determine how electrical energy and natural gas were being used at the facility and to identify and develop potential costsaving projects.

加州的装瓶公司和啤酒厂正受益于一个三步系统评估过程，旨在减少压缩空气系统的电力消耗。该三步工艺通过集中开吹和闲置设备，减少装瓶线对压缩空气的需求，进而提高空压机的比功率(降低能耗)。

评估工程化空气喷嘴的回报和鼓风机升级有各种工厂可以用来从包装中移除或“吹出”水分。打开管或钻孔管通常被视为简单的低成本方法。然而，这些方法存在相当大的缺点，最值得注意的是 - 增加的运营费用。虽然在短期内可能方便且便宜，但这些方法通常花费比优选替代品更高5-7倍。

水锤冲击波是导致水处理站严重损坏或系统故障的一个主要问题。“水锤”或“液压冲击”是流体(通常是液体，但有时也是气体)在运动中被迫停止或突然改变方向(动量改变)时产生的压力波动或冲击波。在停止之前，反向的动量会继续增加。
