Water and wastewater plant maintenance has undergone a revolution. Operators have moved from routinely servicing machinery at predetermined intervals regardless of condition to applying predictive maintenance.Until recently, costly and complex technology and low awareness of alternative solutions have limited predictive maintenance to large or high-value filtration and treatment systems. Now, the falling price of technology makes it easier than ever to monitor the operating condition of more basic yet still critical assets such as pumps, motors and fans.Vibration is a classic indicator of wear, imbalance or misalignment in shafts, bearings and other rotating parts. There are two key advantages to
