Zero discharge of nanofiltration concentrate: A key application of electrodialysis
2025-09-02
Nanofiltration concentrate contains high salt, refractory organic matter and heavy metals. Direct discharge is highly harmful. Zero discharge treatment is an essential need for industrial environmental protection. Electrodialysis, with its characteristic of selective ion migration, has become one of the core technologies for concentrated liquid treatment. It can connect pretreatment and evaporation crystallization, solving the problems of salt separation and concentration.

Membrane separation: Green and efficient acid recovery for rare earth metallurgical leachate
2025-08-13
Rare earth/metallurgical leachate contains 5% to 15% free acid and a large number of metal ions. Traditional treatment methods result in a waste of resources. Membrane chromatography can recover over 80% of free acid, which can be reused after simple treatment. For instance, in the rare earth leaching solution, over 85% of phosphoric acid can be recovered while over 90% of rare earth ions are retained, achieving a "acid-metal" dual cycle.
