Additional Info for Type IV/Pretreatment Design <br /> A. 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+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+Bottom Area =lbs/day/ft2 <br /> mg/L X 8.35+1,000,000 ft2= lbs/day/ft2 <br /> Comments/Special Design Considerations: <br /> I hereby certify that I have completed this work in accordance with all applicable ordinances,rules and laws. <br /> Swedlund Septic �,�,J"� 2502 10/17/14 <br /> (Designer) �' (Signature) (License#) (Date) <br />
