Abstract:

A new method for recycling electr odialysis strong brine is introduced. It consists of advanced water treatment chemicals and techno logy correspondingly. When people produce purewater by electr odialysis, they will get alarge amount of those by-product wastewater electrodi alysis strong brine which is very difficult to be reused. So they normally cast it away. Now using our technical method, the much more corrosive brine whose total Cl^-and SO₄ ^2-as high as 800 mg/ L, can be reused by putting it into industrial cooling water system. Testing results show that treatment effect can arrive at the ‘Good Grade’in SINOPEC standards either anti-corrosionor scale inhibition.

Key words: electrodialysis, strong brine, recycling, industrial cooling water system
