Technology comparisons

Neutral, side-by-side comparisons of the process options we are asked about most often — with the criteria that actually decide the project.

Screw press vs. decanter centrifuge vs. belt filter press

Direct comparison of screw press, decanter centrifuge and belt filter press for sludge dewatering: cake dryness, energy demand, polymer consumption, wash water, noise, staffing and total cost of ownership.

Open comparison

Pile cloth media filter vs. sand filter

Pile cloth media disc filters compared with continuous and rapid sand filters for tertiary treatment: footprint, energy demand, backwash water, achievable TSS, retrofit capability and operating effort.

Open comparison
