Special Issue Information
Dear Colleagues,
Solid–liquid separation technology is a key link in wastewater treatment, especially in the mineral processing and chemical industries, and plays a crucial role in resource recovery and pollution control. Mineral processing wastewater is rich in suspended particles, heavy metal ions, and flotation reagents, while chemical wastewater often contains high concentrations of organic matter, colloids, and difficult-to-degrade substances. Traditional separation methods face challenges such as low efficiency and high cost. The current technologies mainly include sedimentation, filtration, centrifugal separation, flocculation, and membrane separation. For example, the combination of a high-efficiency thickener and a flocculant can achieve rapid solid–liquid separation of tailings water from mineral processing. In the chemical industry, ceramic membranes or electrocoagulation technology is used to treat emulsified oil and high-salinity wastewater. In recent years, the development of new composite flocculants, ultrafiltration reverse osmosis coupling processes, and intelligent separation equipment has significantly improved treatment efficiency and adaptability. This Special Issue will summarize the principles, application status, and optimization directions of solid–liquid separation technology, aiming to provide reference for the efficient purification and resource utilization of wastewater from mineral processing and chemical industries.
The aim of this Special Issue is to compile the latest research advances in solid–liquid separation technology, focusing on new applications and innovations related to the efficient removal of solid particles from wastewater, the effective recovery of solid resources from wastewater, and the control of suspended solids concentration in water. Original research articles and reviews are welcome in this Special Issue. Areas of research may include (but are not limited to) the following:
- Research and application of new efficient solid–liquid separation equipment
- Collaborative optimization of flocculation and sedimentation technology
- Technological innovation in sludge dewatering and resource utilization
- Practice of intelligent control and digital technology in solid–liquid separation
- Development and evaluation of efficient solid–liquid separation technology
- Breakthrough in separation technology for high-difficulty wastewater (such as mineral processing and flotation wastewater, chemical emulsion)
