초록

A desalination process system combining electro-dialysis, reverse osmosis and brine concentration with by-product recovery.

대표청구항 ▼

A process for the purification and desalination of water containing from 500 ppm to 36,000 ppm salt comprising the steps of: (a) selecting the water containing 500 ppm to 3,000 ppm salt; (b) delivering the water containing 500 ppm to 3,000 ppm salt to an electrodialysis unit; (c) producing product water containing less than 500 ppm and reject in the electrodialysis unit; (d) selecting the water containing 3,000 ppm to 7,500 ppm salt; (e) delivering the water containing 3,000 ppm to 7,500 ppm salt and the reject from the electrodialysis unit to a moderate pressure reverse osmosis unit; (f) producing product water containing less than 500 ppm and reject in the moderate pressure reverse osmosis unit; (g) selecting the water containing 7,500 ppm to 36,000 ppm salt; (h) delivering the water containing 7,500 ppm to 36,000 ppm salt and the reject from the moderate pressure reverse osmosis unit to a high-pressure reverse osmosis unit; (i) producing product water containing 300 ppm to 800 ppm and reject in the high-pressure reverse osmosis unit; and (j) blending the product water from the electrodialysis unit, product water from the moderate-pressure reverse osmosis unit and product water from the high-pressure reverse osmosis unit.
