YANTAI, China – SUEZ and Solvay have won a brine treatment contract in the Wanhua Chemical Industry Park in Yantai (Shandong Province).
Located in the coastal city of Yantai, the industry park of Wanhua Chemical is supplied with water by a reverse osmosis desalination plant. As part of the contract, SUEZ and Solvay will provide a treatment line for the brine produced by the desalination process.
Slated to start operation in October 2018, this is the first contract won by the alliance formed between SUEZ and Solvay to jointly develop and market Advanced Oxidation Processes (AOP) in the Chinese market.
The R&D centres of both companies, in China and Zurich, provide the necessary technical support, supplemented by a pilot plant equipment allowing on-site trials in order to optimise both efficiency and cost of treatment for specific effluents.
With a capacity of 24,000 m3/day, this line will treat brine to achieve a quality discharge into the sea, requiring in particular a total nitrogen content of less than 15 mg/L, total organic carbon (TOC)≤ 20 mg/l, biochemical oxygen demand (BOD) ≤ 10 mg/l, SS ≤ 10 mg/l, total phosphorus (TP) ≤ 0,5 mg/l2 , 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 jointly developed by SUEZ and Solvay.
Steve Clark, CEO of SUEZ Asia, said: “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.”
