Additional Info for Type IV/Pretreatment Design <br />A. Calculate the organic loading using option 1 or 2 <br />1. Organic Loading = Pounds of BOD X Units <br />I l1bs/day X I I = I I lbs BOD/day <br />2. Organic Loading to Pretreatment Unit = Design Flow X Estimated BOD in mg/Lin the effluent X 8.35 + 1,000,000 <br />I jgpd X I 1mg/LX 8.35 + 1,000,000 = I l1bs 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 />I l1bs/day + I ln2= I ltbs/daytft2 <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 />d <br /># ---Joseph J Olson 810 09/18/14 <br />(Designer) .~'A" (Signature) (License#) (Date)
