  "text": "The BAT-AELs for emissions to water given in these BAT conclusions refer to values of concentrations (mass of emitted substances per volume of water), expressed in the unit mg/l.\nThese BAT-AELs refer to the average of samples obtained during one year, meaning the flow-weighted average of all 24-hour flow-proportional composite samples, taken in one year with the minimum frequency set for the relevant parameter and under normal operating conditions.\nThe formula for calculating the flow-weighted average of all 24-hour flow-proportional composite samples is:\nc w = ∑ i = 1 n c i q i ∕ ∑ i = 1 n q i where:\ncw flow-weighted average concentration of the parameter;\nn number of measurements;\nci average concentration of the parameter during ith time period;\nqi average flow rate during ith time period.\nTime-proportional sampling can be used provided that sufficient flow stability can be demonstrated.\nAll BAT-AELs for emissions to water apply at the point where the emission leaves the installation.",
