IMPROVED PLANT FOR THE DESALINATION/PURIFICATION OF INDUSTRIAL WASTE AND BRACKISH WATER WITH ZERO LIQUID DISCHARGE

摘要

The invention relates to an improved plant for the desalination/purification of industrial waste and brackish water with zero liquid discharge, including a heat treatment module (23) comprising evaporators and crystallisers; a chemical treatment module (21) for precipitating incrusting calcium and magnesium salts; a mixing container (22); a power and heat source using any power system (12); boron removal filters or membranes; and a purification module (24) for adjusting salinity and other parameters. The invention also includes a treatment module (25) using ion exchange resins, dispensing with chemical treatment, a mechanical vapour-compression module (27) or an electrodialysis module (26) and a nanofiltration module (28) at the outlet of the plants (1 and 9).
