  • The Evolution Of Collector Monitoring Systems
    The Evolution Of Collector Monitoring Systems

    The vast majority of chain and flight collectors in operation throughout the world do not have any form of monitoring system installed to protect against operational failure. Traditional safety devices consist of a shear pin sprocket device, with a limit switch, designed to protect the drive system if a load or torque exceeds the working load of the drive chain; in the event that this occurs, the shear pin will break, the limit switch will be activated, and the drive motor is shut down. This process will typically protect the drive chain and drive motor from failure. When the shear pin breaks, the clarifier is drained, the cause of the overload is established and corrected, a new shear pin is installed, and the collector is placed back in operation.

  • The Role Of Surface Aeration In Wastewater Treatment
    The Role Of Surface Aeration In Wastewater Treatment

    The process of aeration is used to mix, circulate, or dissolve air into a liquid or another substance. Mechanical aeration can reduce the amount of chemicals needed to treat a body of water by providing the oxygen that bacteria need to function properly. There are two common types of water aeration: subsurface and surface. Although subsurface aeration comes to mind first in discussions of wastewater treatment, surface aeration plays an equally important role in oxygenating liquids.
