What we solve
Solving Complex Residual and Sludge Challenges Without CAPEX
We help facilities meet increasingly strict discharge requirements by improving solids separation and wastewater treatment performance.
Our solutions clarify biosolids volumes and produce cleaner effluent, supporting reliable compliance with regulatory standards.
Inefficient solid–liquid separation can lead to unstable treatment performance, high chemical consumption, and rising operating costs.
Orege conditions sludge to improve separation efficiency and enhance pretreatment, thickening, and dewatering performance.
The result is improved hauled sludge volume, clearer filtrate, reduced chemical usage, and more reliable wastewater operations.
Excessive polymer consumption increases operating costs and often signals inefficient sludge treatment. Orege conditions sludge and improves solids separation with innovative technology that enhances process stability while reducing chemical use.
Clients typically achieve 15–20% polymer savings while improving treatment performance.
Rising sludge hauling and disposal costs are often driven by excess water in biosolids. Orege improves sludge thickening and dewatering performance by removing more water and increasing solids concentration.
Because sludge disposal is typically based on wet tonnage, producing drier sludge reduces transport volume, tanker loads, and overall disposal costs.
Aging or underperforming dewatering and thickening equipment can limit wastewater treatment performance and plant capacity. Orege helps optimize the process to improve throughput and cake dryness.
For temporary needs or performance upgrades, our flexible rental solutions provide additional dewatering capacity without capital investment.
Staff shortages and operational demands can make wastewater treatment processes difficult to manage. Orege provides on-site operational support, training, and process expertise to help maintain stable thickening, dewatering, and treatment performance.
Whether during peak sludge management periods or for ongoing assistance, we help ensure your treatment process operates reliably and efficiently.

Orege defines the standard in high-performance biosolids technology
Orege developed advanced sludge conditioning technologies designed to improve solid–liquid separation in wastewater treatment processes.
At the core of our solutions is SLG® (Solid–Liquid–Gas), Orege's patented sludge conditioning technology. SLG® modifies the structure of sludge at the floc level, releasing trapped water and improving the interaction between solids, coagulants, and flocculants.
This conditioning step enhances separation performance across industrial pretreatment, sludge thickening, and sludge dewatering processes.
Integrated into Orege treatment systems, SLG® conditioning improves solids capture, filtrate clarity, and separation stability while reducing polymer and coagulant consumption.
The result is more reliable treatment operations, lower sludge disposal volumes, and improved overall wastewater treatment performance.
We begin with a technical discussion to understand your wastewater process, operational challenges, and treatment objectives. This conversation helps determine whether Orege solutions can deliver measurable performance improvements.
