Calculate the organic loading <br /> 1. Organic Loading to Pretreatment Unit =Design Flow X Estimated BOD in mg/L in the effluent X 8.35 a 1,000,000 <br /> gpd X mg/L X 8.35 '. 1,000,000= lbs. BOD/day <br /> 2. Type of Pretreatment Unit Being Installed: <br /> 3. Calculate Soil Treatment System Organic Loading: BOD concentration after pretreatment a Bottom Area =lbs./day/ft2 <br /> mg/L X 8.35 s 1,000,000 ft2= tbs./day/ftz <br /> Comments/Special Design Considerations: <br /> I hereby certify that I have completed this work in rdance with all icable ordinances, rules and laws. <br /> Mark Tradewell 307 02/11/22 <br /> (Designer) (Signature) (License x1 (Date) <br />
