{ 34.3 Suspended Solids <br /> Suspended solids analyses were completed using Methods 209C and 209D of Standard Methods. The <br /> results of the suspended solids analyses over the entire evaluation are shown in Figure 2. Data from the <br /> suspended solids analyses are summarized in Table I. j <br /> Influent suspended solids: <br /> The influent suspended solids ranged from 34 to 1,600 mg/L during ;the evaluation, with an average <br /> H <br /> oncentration of 291 mg/L. The median influent.suspended solids concentration during the evaluation was <br /> a 200 mg/L. <br /> I <br /> pill: <br /> E Effluent Suspended Solids: <br /> # <br /> The effluent suspended solids concentration ranged from <2 to 42 mg/L during the evaluation, with an <br /> average concentration of 4 mg/L and a median concentration of 3 mg/L. As shown in Figure 2, the maximum <br /> lq <br /> single day effluent suspended solids concentration of 42 mg/L was measured on July 16, near the end of the <br /> 11 <br /> second thirty days of testing, during a period with a 30-day average influei t suspended solids concentration <br /> s of 570 mg/L. <br /> Over the course of the evaluation, ANSVNSF Standard 40 requires that,the effluent suspended solids not <br /> l Iky <br /> exceed 45 mg/L on a 7-day average or 30 mg7L on a 30-day average. Table III shows the 7- and 30-day <br /> Vj <br /> suspended solids averages. C <br /> I� <br /> �l average effluent suspended solids "ranged from 2 to 11 mg/L. and the 30-day averages ranged <br /> The 7-day g <br /> from 3 to 6 mg/L. As shown in Table III, the AdvanTex AX20N met the requirements of ANSI/NSF Standard <br /> t 40 for effluent suspended solids. <br /> 1j, <br /> ifl E ' <br /> it l <br /> { <br /> / E <br /> 01111/20151060 This report may not be reproduced in whole or in°part Page 11 of 46 <br /> I IFina1 Report without the expressed written consent of NSF International.
