PROCESS OF TRANSFORMATION OF POLYAMIDE MEMBRANES WITH SPIRAL REEL, THAT HAVE OUT OF ITS USEFUL LIFE, IN INDUSTRIAL UTILITY MEMBRANES
Patent number:
ES2589151B1
No items found.
Transformation process of polyamide membranes with spiral winding that have exhausted their useful life in membranes of industrial utility. Recycled membranes of nanofiltration or ultrafiltration are obtained with a permeability greater than that of the discarded membrane and with a rejection in divalent salts greater than 30 percent and less than 30 percent, respectively.
