Diffusion dialysis (DD) employing anion exchange membranes (AEMs) presents an attractive opportunity for acid recovery from acidic wastewater. However, challenges exist to make highly permeable AEMs due their low coefficient (Uacid). Here, a series of porous and fabricated based on chloromethyl polyethersulfone (CMPES) membrane substrate with crosslinking quaternization treatments is reported. ...

The application of new technologies in the agro-industrial sector is needed to close loop nutrient cycle food chain. aim this work study feasibility combination two recovery technologies. In a first step, novel gas-permeable membrane technology recovers N from wastewater as an ammonium sulfate solution (a bio-based fertilizer). Secondly, electrodialytic process P, electrolyte solution, which P ...
