Rather than just a static PDF, the "better" approach is to provide a that includes the theoretical formulas and a practical method for calculation (such as an embedded calculator or spreadsheet logic).
[ A_proj = \fracQv_s ] Where ( Q ) is in m³/h, ( v_s ) in m/h → ( A_proj ) in m². cap A sub r equals the fraction with
Here are the essential formulas and steps used in real engineering design.

is ideal to allow settled solids to slide down the plates into the sludge hopper without clogging. 3. Surface Area Loading Rate (SALR) Used to measure the mass of solids treated per unit area:
