PE = population equivalent based on organic constituents in the industrial waste A = industrial waste flow, mg/day B = industrial waste BOD, mg/l 8.34 = number of lb/gal 0.17 = number of lb BOD/person-day

Similar population equivalent calculations can be made for SS, nutrients, and other constituents. Expressing all waste loadings on a similar basis requires population equivalent calculations to be made for various pollutants from both point and nonpoint sources in a geographical
