Wizwater vs Conventional Sludge Handling Technologies
Slow-speed screw operation uses a fraction of the energy vs high-speed centrifuges at 3000–4000 rpm.
No high-speed bearings, no belts to replace, self-cleaning filter rings eliminate manual intervention.
Combined dewatering + drying achieves industry-leading volume reduction — saving disposal cost.
Slow rotational speed results in quiet, vibration-free operation — suitable for urban plant locations.

| Long-Term Operating Cost | Lowest | Highest | Medium |
Among all sludge dewatering technologies, the Screw Press + Sludge Dryer system offers the best balance of low operating cost, reliability and simple operation — making it ideal for industrial and municipal wastewater treatment plants.
A typical process flow showing where each Wizwater system fits in the treatment plant.
Raw wastewater passes through screening systems to remove large debris and floating solids, protecting downstream equipment.
Balances flow fluctuations and pollutant concentration variations to stabilize the treatment process and prevent shock loads.
Micro air bubbles attach to flocs and float suspended solids, oils and grease to the surface for mechanical removal.
Microorganisms degrade dissolved organic pollutants, reducing BOD and COD levels to meet discharge standards.
Sludge is mechanically compressed through the screw press to produce dewatered sludge cake, reducing volume and transport cost.
Heat pump technology reduces sludge moisture below 10%, achieving 80–90% volume reduction for minimal final disposal cost.
