Slow Rate Sand Filtration With And Without Clinoptilolite: A Comparison Of Water Quality And Filtration Economics, Gordon P. Foreman
Slow Rate Sand Filtration With And Without Clinoptilolite: A Comparison Of Water Quality And Filtration Economics, Gordon P. Foreman
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Slow rate sand filtration (SSF) amended with a 20 cm surface layer of clinoptilolite, a natural zeolite, was compared to SSF with no amendment in a field scale SSF facility treating 85 m3/d of water. Parameters examined included turbidity, coliforms, and ammonium removal. The control filter with sand and the experimental filter amended with the zeolite were also compared with respect to duration of filter cycle, cold weather operation, and economics.
Amended and unamended filters were approximately equivalent with respect to ammonium and coliform removal at 10° C. The zeolite amended cell was superior to the unamended cell …
