DTZ Hybrid Sludge Dewatering by Alfa Laval and Orege
Advanced Biosolids Dewatering: A Hybrid Technology Approach
Smarter Dewatering Starts Upstream
Alfa Laval and Orege are partnering to bring a new approach to biosolids dewatering combining advanced sludge conditioning, high-efficiency thickening, and proven dewatering in one compact solution. Built for municipal and industrial wastewater applications, this hybrid system helps operators improve overall dewatering performance, address key operating cost drivers, and work within real-world plant constraints.
Today’s dewatering demands more
Wastewater operators are under pressure to do more with less: less space, less water, less chemical use, and lower hauling and disposal costs.
Conventional dewatering approaches can struggle to keep up with these pressures, especially when feed variability, footprint constraints, and operating efficiency all matter.
That’s why Alfa Laval and Orege are introducing a hybrid approach designed to support stronger downstream dewatering results through improved upstream sludge conditioning and thickening.
A hybrid solution designed for better outcomes
The Alfa Laval–Orege solution integrates three critical steps into one compact system:
- Advanced sludge conditioning with Orege SLG®
- Rotary drum thickening with FloSep
- Final dewatering with Alfa Laval’s vertical pressure belt filter press
By improving sludge structure before final dewatering, the system helps unlock more consistent dewatering performance, stronger solids capture, and improved process efficiency without requiring operators to move away from familiar belt press operation.
Why this hybrid approach matters
- Improved dewatering process performance
- Lower polymer, washwater, maintenance, and disposal-related cost drivers
- Compact, retrofit-friendly footprint
- Familiar operation with reduced change-management risk
- A more sustainable approach to biosolids handling
Two complementary technologies. One stronger solution.
This partnership brings together Alfa Laval’s expertise in separation and dewatering with Orege’s innovative sludge conditioning and mobile wastewater solutions.
Together, we are creating a more integrated and effective way to address the operational, economic, and sustainability challenges facing wastewater treatment today.
