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 I lbs/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 lgpd X I lmg/L X 8.35 + 1,000,000 = I I tbs BOD/day <br />B. Type of Pretreatment Unit Being Installed: <br />C. Calculate Soil Treatment System Organic Loading: lbs . BODI day 1-Bottom Area = lbs/ day /ft2 <br />I I lbs/day 1-I l1t2 = I llbs/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 <br />y-- <br />810 09/23/14 <br />(Designer) ,,,.
