For purposes of determining system performance, only samples collected during design loading periods, <br /> described in 8.2.2, shall be used in the calculations.The data collected during the stress sequences shall not <br /> be included in the calculations, but shall be included in the final report. <br /> 8.4.3.1 CBOD5 <br /> The average CBOD5 of all effluent samples shall not exceed 25 mg/L. <br /> 8.4.3.2 TSS <br /> The average TSS of all effluent samples shall not exceed 30 mg/L. <br /> 8.4.3.3 Total nitrogen <br /> The average total nitrogen concentration of all effluent samples shall be less than 50% of the average total <br /> nitrogen concentration of all influent samples. <br /> 8.4.3.4 pH <br /> The pH of individual effluent samples shall be between 6.0 and 9.0 SU. <br /> 8.4.4 Air pressure and flow <br /> There are no criteria for aerator pressure or flow. Pressure and flow are measured for the purpose of <br /> qualifying alternate aerators following the test. <br /> 8.5 Final report <br /> A final report shall be prepared that presents the following: <br /> — all data collected in accordance with the testing and evaluations within this Standard; <br /> — a table indicating the actual percent reduction over the course of the test (included in the <br /> Executive Summary, as well as in the body, of the report); <br /> —observations made during the testing; <br /> —an estimation of the pounds of nitrogen loaded during the test and the pounds removed; <br /> —any adjustments made to the alkalinity of the influent wastewater; <br /> — a copy of the current edition of the Owner's Manual; and <br /> — process description and detailed dimensioned drawings of the system evaluated. <br /> A supplemental report shall be prepared for any system(s) approved under the performance classification <br /> section (1.4) of this Standard, including process description(s) and dimensioned drawings. <br /> 15/10/055/0030 This report may not be reproduced in whole or in part Page 32 of 64 <br /> Final Nitrogen Report without the expressed written consent of NSF International June 2019 <br />
