Additional Info for Type IV/Pretreatment Design A. Calculate the organic loading 1. Organic Loading to Pretreatment Unit = Design Flow X Estimcted BOD in mg/L in the effluent X 8.35: 1,000,000 gpd X mg/L X 8.35: 1.000,000 = C=ibs BODiday 2. Type of Pretreatment Unit Being Installed: 3. Calculate Soil Treatment System Organic Loading: BOD concentration after pretreatment = Bottom Area = lbs/day/ft' mg/L X 8.35 _ 1.000,000 s =ft' = E=lbs/day/ft` Comments/Special Design Considerations: I hereby certify that I have completed this work in accordance with all applicable ordinances, rules and laws. f ' Joseph J Olosn 810 05/27/16 (Designer) (Signature) (License «) (Date)
