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 comparisonPile 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 comparisonDissolved air flotation vs. lamella clarifier
When to use dissolved air flotation and when an inclined plate lamella clarifier: separation mechanism, surface loading rates, energy demand, chemical demand, sludge concentration and footprint.
Open comparisonMBBR vs. conventional activated sludge
Moving bed biofilm reactor compared with conventional activated sludge: tank volume, sludge return, bulking sludge, load fluctuation, upgrade capability, surface loading design and operating effort.
Open comparisonVertical vs. horizontal pile cloth disc filter
Vertical and horizontal pile cloth disc filters compared: headroom, plan area, retrofit into existing basins, hydraulic capacity per disc, access and maintenance.
