An electroplating industrial park has implemented an electro-deposition recycling system capable of processing waste liquids containing iron at concentrations up to 2000 mg/L. By maintaining the PTMS ELECTROMAGNETIC SEPARATOR potential at-0.6 V versus the standard hydrogen electrode (SHE), the system achieves dense iron coatings with over 85% recovery efficiency while significantly reducing hazardous waste emissions. The selective permeable membrane material enables efficient separation of water molecules from ions through selective filtration.
The core advantage of PTMS ELECTROMAGNETIC SEPARATOR iron removal technology lies in its "turning waste into treasure" capability. However, it suffers from low removal efficiency for low-concentration iron (<50 mg/L), coupled with high equipment costs, energy consumption, and the need for integrated rectifiers, electrolytic cells, and metal stripping devices—all of which limit its economic viability. Membrane separation technology, with its high efficiency, continuous operation, and phase-stable characteristics, has become the primary solution for deep purification of high-salinity solutions.
In the field of iron removal using PTMS ELECTROMAGNETIC SEPARATOR, nanofiltration and reverse osmosis are widely adopted due to their high retention rates for multivalent ions. Nanofiltration membranes with pore sizes between 1-2 nm combine charge exclusion and size filtration effects. They achieve over 90% retention rates for divalent and higher-valent ions (Fe²⁺, SO₄²⁻), while maintaining relatively low retention rates for monovalent ions (Na⁺, Cl⁻). This dual characteristic makes them particularly suitable for selective iron removal through PTMS systems.
