Description
Components:
- Supercritical Fluid Reactor: The core of the SCWP technology, where supercritical water (water at conditions above its critical point - 374°C and 22.1 MPa) is used as a medium for the precipitation of dissolved metals.
- Control System: An advanced automation and control system for regulating temperature, pressure, and flow rates within the reactor.
- Input Module: A system for feeding industrial wastewater containing dissolved metals into the reactor.
- Separation Unit: After the precipitation process, this unit separates the solid metal precipitates from the supercritical water.
- Cooling and Condensation System: Cools the supercritical water post-precipitation, returning it to a liquid state for reuse or disposal.
Application Scope:
- Industrial Wastewater Treatment: Especially effective for wastewater from electroplating, mining, electronics manufacturing, and battery production industries.
- Resource Recovery: Efficiently recovers critical metals like lithium, nickel, cobalt, copper, and precious metals from wastewater streams.
Key Advantages and Unique Features:
- High Efficiency: Over 99% recovery rate for various metals, significantly higher than traditional methods.
- Eco-Friendly: Reduces the environmental impact by minimizing waste and eliminating the need for hazardous chemicals.
- Versatility: Can handle a variety of metal-laden wastewater streams, adapting to different metal concentrations and types.
- Cost-Effective: Lower operational expenses compared to conventional methods, due to reduced chemical and energy usage.
- Compact and Modular: The technology's modular nature allows for scalability and easy integration into existing industrial processes.
Ground-Breaking Aspects:
- Innovative Use of Supercritical Water: Utilizing supercritical water for metal precipitation is a novel approach, leveraging its unique solvent properties to efficiently recover dissolved metals.
- Automation and Control: Advanced automation enhances the process's precision and efficiency, making it groundbreaking in terms of operational control.
Practical Functioning:
- Industrial wastewater is fed into the supercritical fluid reactor.
- Within the reactor, supercritical water conditions induce the precipitation of dissolved metals as solid particles.
- These metal precipitates are then separated from the water, leaving behind clean water and concentrated metal particles.
- The clean water can be reused or safely discharged, while the recovered metals, in forms like oxides or hydroxides, can be further processed or sold.
This technology represents a significant advancement in wastewater treatment and metal recovery, offering an innovative, sustainable solution for industries dealing with metal-laden wastewater.
