6 Overview Products Machines: TurboDrainTM WinklePressTM Cascade STM
dewatering screen for sludge thickening TDC, TDH, TDH-L belt press for sludge dewatering WPN G, WPN K, WPN I, WPH TurboDrainTM & WinklePressTM

7 The BELLMER TurboDrain ™

8 TURBODRAIN™ Revolving belt Chicanes Odout hood (Optional) Ramp
Thickened sludge discharge Drive Discharge Chute (Optional) Patented feed and maturing chamber Feed for flocculated suspension Clear Filtrate Spray Water

9 TURBODRAIN versus final clarification or DAF
Sometimes a picture is worth more than 1000 words Final clarification or DAF ± 40 kW ± 8 kW TDN building Volume: 9000 m³ Volume: 180 m³

Practically solids-free filtrate

12 The BELLMER WinklePress™

13 BELLMER Winklepress WPN-K unique dewatering sections

14 BELLMER Cascade S

15 BELLMER Cascade S Turbodrain reduces the hydraulic throughput
1. sludge feed 2. filtrate outlet 3. waste water outlet Turbodrain reduces the hydraulic throughput transfer chute 2. 3. 1. spreader box Winklepress WPN Winklepress dewaters the sludge to highest dry solids dropping of the dewatered sludge filtrate waste water

16 Comparison WPN vs. Centrifuge
Cake dry solids content: 28 % Polymer consumption (6-8 kg/t DS) Low energy comsumption (4-5 kW) Low maintenance costs Clear filtrate: ~ 500 mg/l Cake dry solids content: 28 % Polymer consumption (13-15 kg/t DS) Low energy comsumption (40-50 kW) High maintenance costs - fast running machine Dirty filtrate: ~ 2000 mg/l

17 Savings by Using a Winklepress instead of a Centrifuge
Operation costs: Filtrate quality – 1500 mg/l Energy kWh/a Polymer kg/a Costs €/a Costs €/a Costs €/a (for 0,15 €/kWh) (for 2,0 €/kg Polymer and t/a biosludge) Location Centrifuge EUR/t Winklepress Difference Utrecht 386 327 59 Nieuwegein 345 41

18 Conclusion Saving 80% Saving 90% Power Consumption: TurboDrain™ vs DAF
± 8kW ± 40kW Saving 80% WinklePress™ vs Centrifuge ± 5kW ± 50kW Saving 90%

19 Reference Metsä Tissue Raubach Savings
