Brussels/Belgium — Located in the coastal city of Yantai, the industry park of Wanhua Chemical, a global chemical company, is supplied with water by a reverse osmosis desalination plant. The contract provides a treatment line for the brine produced by the desalination process.

With a capacity of 24 000 m3/day, this line will treat brine to achieve a quality discharge into the sea, in accordance with the most recent standards of the chemical industry, requiring in particular a total TN content of less than 15 mg/L, TOC ≤ 20 mg/l, BOD ≤ 10 mg/l, SS ≤ 10 mg/l, TP ≤ 0,5 mg/l, etc. This treatment line will be equipped with Suez’s patented technologies (Densadeg, Biofor DN, Oxyblue, Flopac, Ozonia XF) as well as the Advanced Oxidation Process (AOP) jointly developed by the companies to achieve the optimum treatment of brine and optimize the operational costs. It will start operation in October, 2018.

Steve Clark, CEO of Suez Asia says “Tighter Chinese regulations require the deployment of more and more advanced treatments involving cutting-edge technologies that combines the expertise of several players. The innovative technologies and business model offered by Suez and Solvay represent a flexible and cost effective solution to ensure the treatment of complex effluents from all industrial sectors.”
