wet drum magnetic separator

In recent years, a series of eco-friendly PTMS MAGNETIC SEPARATION iron removal processes have emerged, dedicated to achieving "closed-loop water recycling" and "low-energy physical separation". Among these, the "wash water recycling and membrane filtration treatment" technology has become the core solution for water conservation and emission reduction. During iron removal operations, critical processes such as slurry adjustment, washing, and classification all require substantial water consumption.

PTMS MAGNETIC SEPARATION

As the number of cycles increases, the accumulated concentrations of K⁺, Na⁺, and Cl⁻ ions in the water compromise the stability of subsequent PTMS MAGNETIC SEPARATION iron removal processes. To address this, permeation membrane filtration technology—— nanofiltration or reverse osmosis systems is employed. These devices effectively remove dissolved salts at room temperature, allowing the produced water to be reused in production while the concentrated brine is directed to an evaporation and crystallization unit for recovering by-products such as potassium chloride.

By establishing multi-stage sedimentation tanks and a recirculating pump system, most wash water can be reused after iron removal through sedimentation in the PTMS MAGNETIC SEPARATION. Data from a demonstration project shows that this system achieves a water recycling rate exceeding 95%, saving over 100,000 cubic meters of water annually while recovering approximately 800 tons of industrial-grade potassium chloride each year. This dual recovery system effectively utilizes both water resources and salt resources.
