Wastewater loading
Convert concentration and daily flow into mass and volumetric loads.
Equation and assumptions
Load = Q × C / 1000 [kg/day]; volumetric load = Load / V
Steady average flow and a representative concentration of a specified pollutant. Does not establish treatment capacity, removal performance, sludge age or discharge compliance.
