The salt content of well brine is as high as 30g, and it has gradually become the basic raw material for chlor alkali industry production. Untreated brine contains a large amount of sulfate ions, which can easily lead to anode discharge during the electrolysis process of chlor alkali membrane production, causing damage to the anode. Therefore, the process requires denitrification treatment of the brine to reduce the sulfate ion content.
\nUsing tubular membranes and nanofiltration membranes to refine brine, the sulfate content of the brine after passing through the nanofiltration membrane is less than 0.5q, fully meeting the production requirements of the chlor alkali industry; In addition, the concentrated solution of nanofiltration membrane contains a large amount of sulfate ions, with a content of up to 90g, which is much higher than the standard of 3g for high nitrate water. It can be used as a high nitrate water for frozen denitrification in saltpeter plants to extract saltpeter.<\/p>\n

Advantages of membrane brine treatment
\n1. The system has a high degree of automation and low labor costs. 2. The process configuration is reasonable, and the membrane flux is greatly improved. 3. The economic benefits of reusing permeate are lower than production costs. 4. It not only meets the production needs of the chlor alkali industry, but also opens up new product markets<\/p>\n","protected":false},"excerpt":{"rendered":"
