Additional Info for Type IV/Pretreatment Design A. Calculate the organic loading using option I or 2 1. Organic Loading =Pounds of BOO X Units lbs/day X lbs BOD/day 2. Organic Loading to Pretreatment Unit =Design Flow X Estimated BOO in mg/L in the effluent X 8.35+1,000,000 gpd X mg/L X 8.35+1,000,000= lbs BOD/day B. Type of Pretreatment Unit Being Installed: C. Calculate Soil Treatment System Organic Loading: lbs.BOD/day+Bottom Area =lbs/day/ft2 lbs/day+ ft2= lbs/day/ft2 Comments/Special Design Considerations: I hereby certify that I have Completed this work in accordance with all applicable ordinances,rules and laws.
