Deep-Aeration with Robox Screw Compressors
Two Robox Screw WS 85 compressors replaced legacy units in 2012. Operating at 110 kW and 2,080 m³/h, they support 17-meter-deep aeration tanks with high oxygen absorption. Key features:
- Low energy consumption and noise (70 dB(A))
- Premium Efficiency IE3 motors
- Sentinel Pro electronic control panel with MODBUS alerts
- Oversized bearings and seals for durability
- Easy front access for daily maintenance
Biological Water Line
Three Robuschi S 125/4P rotary lobe blowers (132 kW, 3,750 m³/h at 750 mbarg) manage oxygen demand via frequency control. Installed during the 2005 upgrade, they support active sedimentation in aeration tanks.
Biogas Recovery
The compact sediment fermentation plant processes sludge from Dendermonde and nearby towns. Two KRVS 23 TM-CT liquid ring compressors (Atex-certified, stainless steel impellers) power the biogas motor and CHP unit, enabling the plant to meet its own energy needs. These contactless compressors replaced high-maintenance predecessors and are less prone to contamination
