This article discusses an accurate, sensitive turbidimeter that continuously reads and records data that will be of great value to the water supply industry. The low‐range turbidimeter has been used extensively in plant scale and pilot plant research on high‐rate filtration at Iowa State University, Ames, Iowa, and at the Ames treatment plant. It has great potential value in filter control. The article discusses calibration of the turbidimeter, along with three important uses of the turbidimeter that include selection of proper time to backwash filter, the feasibility of high filtration rates, and the effect of plant operational practices on effluent water quality.
