1. A continuous solid bowl (decanter) centrifuge was able to meet the needs of treating a small stream wastewater containing ferric hydroxide. 2. It required >3000 g-force to obtain dry cake and clear enough centrate due to the small particle size of Fe(OH)_3. 3. It is relatively simple to select the full-size centrifuge for the plant operation based on the scale-up factor from the manufacturer.
