It was now conjectured that intermittent back washing could overcome the difficulties. This procedure was now introduced with influent flow rate and collar screen mesh varied.

The results of this experiment lead to a removal efficiency of with a retreated flow of only . This was regarded as a satisfactory and practical solution, and the investigation was terminated at that point.

For detailed analysis of this experiment, the reader should refer to Box et al. (1978, p. 354). Of course, these types of experiments and their analyses are discussed in this text (see Chapter 18).
