0.14 NTiJ would be reported as a 0.1 NTU reading. The repordng forms require that the <br />maximum and mirumum turbidity readings be rounded to the neazest 0.01 NTU and that <br />the perceniage above 0.1 NTiJ can be rounded to the neazest 0.1 percent (4) Figures 14 <br />and 15 depict the filtered water turbidity and the percent frequency occurrence, <br />respecrively. <br />Figure 14: Filtered R'ater Turbidity <br />Brown County W ID [`(o. 1 <br />M aximum Deily Filtered W ater Turbldity <br />~ <br />g <br />a <br />~ <br />~.•arn ~vum nnu.r ..l` ivvrn un••n n. <br />D <br />Figure 15: Filtered Water Turbidity in Percent Frequency <br />B r o w n C o u n t y W I D N o. 1~ <br />Frequency Plot of M azlmum Daily Filtered W ater Turbidity <br />. <br />~ . <br />. ..""..."'......"'""...1 <br /> <br /> <br /> <br />. <br />~ u. n. n <br />r.r<..t.c..rne+aI.V<-crnwi4*s~.•• <br />C. Filter with Post-Backwash Performance <br />The program requires that plants generate a filter run profile for each filter at least once <br />each month, using a continuous online turbidity meter. The plant must record the data <br />using a strip char~ circulaz chart, or computer or other device capable of producing a <br />hard copy of the results.
