Transform your sludge into a valuable resource
With the right strategy, your sludge can become more than a by-product of wastewater processing - it can become a source of operational and environmental value. Our comprehensive portfolio of lime-based solutions is designed to improve dewatering, enhance stabilization, support drying, and enable safe and cost-effective sludge management for municipalities and industries.
Thickening and dewatering
Reducing sludge volume is the first step to lowering costs and improving operational efficiency. With lime treatment, you can achieve higher dry solids content, boost dewatering performance, simplify handling, and significantly cut transport and disposal expenses.
Drying
Drying plays a crucial role in shrinking sludge volume even further. Our lime-based reagents help you accelerate evaporation, reduce energy demand, and produce a lighter, more stable sludge. The result: easier handling, more efficient transport, and lower overall treatment costs.
Stabilization
Safe sludge management starts with proper stabilization. Lime offers you a powerful, economical, and proven solution to:
- Reduce pathogen levels
- Eliminate odors
- Keep metals in insoluble form
- Improve handling and operational safety
- Increase valuable calcium and magnesium for agricultural reuse
This makes lime stabilization an attractive alternative to more capital‑intensive thermal or biological treatment methods.
Nutrient recovery
Phosphorus is a limited resource - and regulatory frameworks increasingly require its recovery. Our lime-based reagents help you recover phosphorus efficiently from sludge liquor, digested sludge, or incinerated ash enabling circular, resource-positive solutions that support your sustainability objectives.
Optimized sludge treatment tailored to your facility
Every sludge stream has its own characteristics - from volume and composition to regulatory requirements and reuse pathways. With our lime-based solutions, including Neutralac® for wastewater and sludge applications, you gain a flexible, robust treatment approach that enhances process stability and efficiency.
