This preliminary report presents an evaluation of survey data collected at municipal diatomite filter plants in New York State. The main focus of the report is on an assessment of source raw‐water quality experienced at diatomite installations, and plant operational flexibility in sustaining a continuity of filtration cycles under varying raw‐water quality. Early in the survey, it was recognized that in order to objectively assess source raw‐water quality, turbidity measurements alone would not suffice. In view of this, microscopic examinations of water samples for determination of total count, expressed as standard units per milliliter, were adopted as an index of water quality. It was assumed that this parameter could be considered as the primary head loss contribution to diatomite filtration at sources having no appreciable amounts of inorganic clay or silt.
