Reducing the flow to 400 gpd does <br /> not seem to have had an impact (either positive and negative) on effluent CBOD5 values. <br /> L <br /> Figure 6: Effluent CBOD — 7 Day Averages <br /> L Bo <br /> Pipe <br /> 8=stress test Replaced <br /> 1 50 <br /> ` Mdsl Ur l=40 mgfL 5 Manifold Replaced <br /> 40 <br /> Dosing Flow <br /> Frequency <br /> SS S Increased to 4�0 gptl <br /> 30 <br /> L 20 <br /> s <br /> 1g s <br /> s <br /> s <br /> s <br /> 0 5 10 15 20 25 30 35 40 45 50 55 <br /> 7 Day period <br /> L The NSF/ANSI Standard 40 7-day limit of 40 mg/L was exceeded on Weeks 21, 24, 25, 26 <br /> and 27. <br /> f <br /> L <br /> NovaTec Consultants Inc.
