The TSS results over the entire evaluation are shown in Figure 2. Data from the TSS analyses are <br /> summarized in Table I. <br /> Influent TSS: <br /> The influent TSS ranged from 70 to 430 mg/L during the evaluation, with an average and median <br /> concentrations of 180 mg/L. The 30-day average concentrations during the test ranged from 130 to 210 <br /> mg/L. <br /> Effluent TSS: <br /> The effluent TSS concentration ranged from <2 to 57 mg/L during the evaluation, with an average <br /> concentration of 10 mf/L and a median concentration of 7 mg/L. <br /> 15/10/055/0030 This report may not be reproduced in whole or in part Page 12 of 59 <br /> Final Report without the expressed written consent of NSF International January 2019 <br />
