Decanter Centrifuge Throughput Guidelines
for small to medium throughput rates. The newer Alfa Laval nomenclature specifies an inflow range of approximately 1.3 m3/h for the smaller ALDEC 20 in a standard sludge dewatering application.

Medium Typical Throughput
Sewage sludge dewatering 1–5 m3/h
Industrial sludge 1–8 m3/h
Thin suspensions 5–15 m3/h
Process water with low solids content up to approx. 20 m3/h
