Because the plates are inclined, the total physical area of the plates is not the same as the horizontal projected area used for settling. For plates of width and length , inclined at angle (typically 55–60°):

While hydraulic SOR is common, (kg/m²·h) determines sludge blanket depth.
Usually based on the plate width plus side clearance for supports. Includes the plate pack height ( ), inlet zone depth, clear water zone ( m), and sludge hopper depth. 3. Key Design Parameters & Guidelines Plate Angle: 55 raised to the composed with power is common for general wastewater; angles less than 45 raised to the composed with power may lead to sludge accumulation and clogging. Hydraulic Retention Time (HRT): Often as low as
Round up to the nearest whole number to ensure sufficient capacity. 5. Estimate Tank Dimensions
