Pilot plant research conducted in 1974 at Duluth, Minnesota, demonstrated that asbestiform fibers counts in Lake Superior water could be effectively reduced by municipal filtration plants. During the study engineering data were also obtained for making cost estimates for construction and operation of both granular and diatomaceous earth (DE) filtration plants ranging in size from 0.03 to 30 mgd. During one phase of the pilot plant investigation, the diatomite filters were operated in a way that yielded data used for computer optimization of the DE filtration process. The POPO (Program for Optimization of Plant Operation) results are presented in Appendix I.
