Learn how pollutant load, SALR, protected surface area, media volume and fill ratio work together in preliminary MBBR sizing—and why tank volume alone is not enough.

Learn how sludge flow, feed solids concentration, dry-solids load, operating hours and sludge type affect screw press sizing—and why m³/h alone is not enough.
