In the demanding world of coal preparation, water is not just a resource—it’s the lifeblood of the entire operation. From dust suppression to dense media separation and washing, every stage depends on a reliable supply of quality water. However, with increasing environmental regulations, rising operational costs, and the constant pressure to improve yield, managing this critical asset has never been more challenging.
Coal preparation and washing processes are inherently water-intensive. The resulting wastewater is often laden with suspended solids, fine coal particles, magnetite, and dissolved minerals, creating a complex challenge. How do you meet stringent discharge standards while minimizing the cost of freshwater intake and maximizing resource recovery?
The answer lies in a smarter, more integrated approach to water management. At NuWater, we deliver modular, scalable, and energy-efficient water treatment technologies designed specifically for the coal industry. Our goal is simple: to help you transform your water loop from a costly necessity into a high-value operational asset.
NuWater’s Integrated Solutions for Coal Prep Plants
A one-size-fits-all approach doesn’t work in coal beneficiation. That’s why we offer a comprehensive suite of technologies that can be combined to create a tailored solution for your plant’s specific needs.
Starting with Solids: High-Rate Clarification & Sedimentation
The first step in any effective water treatment circuit is managing suspended solids. Our high-rate clarification and sedimentation systems are engineered to efficiently separate coarse solids, fines, and valuable magnetite from large volumes of process water, preparing it for further purification and reuse.
Refining the Stream: Ultrafiltration (UF) for Fines & Colloidal Removal
For reliable reuse in critical washing circuits, process water must be free of fine suspended solids and colloids that can foul downstream equipment. NuWater’s Ultrafiltration (UF) systems provide a robust physical barrier, ensuring consistent, high-quality water and protecting more sensitive technologies like Reverse Osmosis.
Polishing for Peak Performance: Reverse Osmosis (RO) & Nanofiltration (NF)
When high-purity water is required for boiler feed or specialized processes, Reverse Osmosis (RO) and Nanofiltration (NF) are essential. These technologies remove dissolved salts and minerals, allowing you to create a closed-loop system that dramatically reduces your reliance on fresh water sources and lowers overall operational costs.
Achieving Full Compliance: Zero Liquid Discharge (ZLD) & Brine Management
For operations facing the strictest environmental regulations, achieving Zero Liquid Discharge (ZLD) is the ultimate goal. Our expertise in brine management and ZLD systems ensures your plant complies with all discharge standards, future-proofing your operation against regulatory changes and reinforcing your commitment to sustainability.
Beyond Water Treatment: Unlocking Hidden Value in Your Process Stream
Effective water management isn’t just about cleaning and reusing water; it’s about recovering valuable resources that would otherwise be lost to tailings ponds. This is where NuWater’s technical edge truly shines.
Valuable Fines Recovery: Don’t let profit slip away. Our integration of membrane-based separation and advanced flotation can concentrate and recover ultra-fine coal particles from your process stream, directly increasing your plant’s overall yield.
Near-Complete Magnetite Recovery: Magnetite is a significant operational expense in dense media separation. By combining clarification, hydro cyclone separation, and UF polishing, our systems enable near-complete recovery of magnetite, drastically reducing your make-up costs and improving process efficiency.
Chemical Reuse: Our tailored treatment schemes can be designed to recover and recycle conditioning chemicals, further reducing your operational expenditure (OPEX) and minimizing your environmental footprint.
