  • Screening Considerations – A Guide to Selection

    The perforated band screen consists of perforated plate panels attached to a drive chain. Together with Rotary Drum Screen, the perforated band screen has the highest screenings capture rate of any fine screen. Screening capture rates are as high as 90%. It is important to note that a higher screenings capture rate is not necessarily better than a lower one. The required screening capture rate for a plant should be evaluated early into the design process as it will greatly influence the operation of a WWTP. Together with the unwanted materials such as inorganic material, organic matter will be removed as well. This high amount of organic matter must be re-captured and returned to the WWTP by the utilization of advanced washer/compactor equipment. This is extremely important for band screens used for “regular” WWTP’s. It is of much lesser importance if the band screens are used for MBR applications where the waste water has already been screened and de-gritted.
