In anode material manufacturing, ERAGON ENVIRO TECH has developed mature solutions for waste acid and wastewater treatment. Based on ion-exchange membrane technology and ZLD expertise, our process integrates treatment with resource recovery.

Through customized ion-exchange membrane modules and precise process control, our system removes over 90% of impurity ions, achieving >80% acid recovery rate. The regenerated acid is directly reused in production, cutting raw acid costs.

For wastewater, our stepwise separation process recovers valuable byproducts such as calcium fluoride and calcium chloride, reducing solid waste while generating additional revenue. From process design to O&M, we ensure stable operation tailored to different anode material plants, enabling compliance and circular resource use.

For battery recycling, ERAGON ENVIRO TECH provides reliable treatment packages for wastewater streams containing heavy metals and salts from pyrometallurgical and hydrometallurgical processes.

By combining multi-pressure membrane systems with optimized evaporation–crystallization, our solution achieves high concentration ratios, energy savings, and stable operation under high-salinity conditions. This effectively addresses fouling and instability issues of conventional systems.

Our turnkey services ensure customized solutions that achieve compliance and maximize resource recovery, enabling green production for battery recycling enterprises.

In cathode precursor production, wastewater typically contains high-salt sulfates (sodium, ammonium, phosphate) and lithium, with complex impurities. ERAGON ENVIRO TECH’s multi-stage membrane + crystallization coupling technology enables efficient separation and recovery of these byproducts with industrial-grade purity, suitable for reuse or sale. Lithium is enriched and recovered via selective adsorption or high-concentration processes, maximizing resource utilization.

We support customers from lab testing to engineering implementation and O&M, ensuring each system is adapted to specific plant conditions. Our solutions deliver regulatory compliance, economic value, and sustainability for cathode precursor enterprises.
