The Lektratek adjustable tilting weir is ideal for varying the immersion, and hence the oxygenation transfer rate of aerators, and has been designed for an absolute minimum of leakage. Operation of the weir is simple with a minimum of moving parts under water or inaccessible beneath the platform level. A manually operated hand wheel is normally provided but this can be upgraded to an electric actuator if required.
Flow Control Gates, manually or automatically controlled, can be supplied for channel or wall mounting applications in a variety of materials to suit all operating and environmental conditions.
Used primarily for sludge removal from clarifiers, the Lektratek telescopic valve design have a proven track record and are simple to operate.
