Additional Info for Type IV/Pretreatment Design <br /> A. Calculate the organic loading using option I or 2 <br /> 1. Organic Loading =Pounds of BOD X Units <br /> lbs/day X lbs BOD/day <br /> 2. Organic Loading to Pretreatment Unit =Design Flow X Estimated BOD in mg/L in the effluent X 8.35-1-1,000,000 <br /> gpd X mg/L X 8.35+1,000,000= lbs BOD/day <br /> B. Type of Pretreatment Unit Being Installed: <br /> C. Calculate Soil Treatment System Organic Loading: lbs.BOD/day Bottom Area =lbs/day/ft2 <br /> lbs/day= 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 /> Joseph J Olson �� 810 02/04/14 <br /> (Designer) (Signature) (License#) (Date) <br />
