本研究的目的是确定用不同的空气和水流量组合清洗全尺寸双介质过滤器的有效性，并从这些数据中推断出提供最佳清洗的流量组合。这项研究是首次全面评估塌陷脉冲清洗过滤介质的有效性。作者建议，将本研究中包含的信息纳入水处理厂过滤器的设计参数，可以实现高效、有效的反冲洗，从而确保更长的过滤器运行时间，防止因反冲洗程序无效而产生泥球和其他问题。

The objective of this study was to determine the effectiveness of cleaning a full-scale dual media filter with different combinations of air and water flow rates, and to deduce from this data the flow combinations that provide optimum cleaning. This study is the first full-scale evaluation of the effectiveness of collapse-pulsing for cleaning filter media. The authors recommend that incorporating the information contained in this study into the design parameters for water treatment plant filters can lead to efficient and effective backwashing thereby ensuring longer filter runs and prevention of mudballs and other problems caused by ineffective backwash procedures.
