Recently, Welly Group successfully signed the Yunnan Xiangfeng industrial wastewater and phosphogypsum rain water comprehensive utilization sewage treatment station concentrated water zero discharge transformation general contract project. The design of this project is 200m³/h for deep treatment and reuse of reclaimed water, and 60m³/h for high concentration and zero discharge. The quality of the produced water meets the water quality standard of reuse water in "Municipal Sewage Recycling - Industrial Water Quality" (GB/T 19923-2005).

Yunnan Xiangfeng Industrial Group is a leading enterprise in the phosphorus chemical industry in China, known for its excellent production capacity of phosphate compound fertilizer and nitrogen fertilizer. The company has an annual production capacity of 3 million tons of fertilizer and 600,000 tons of chemical products, and is at the forefront of the industry in phosphogypsum treatment technology. Xiangfeng Industry actively responds to the national environmental protection policy, has made remarkable achievements in industrial wastewater treatment, carbon emission reduction and clean energy utilization, and has become one of the key forces to promote the green transformation of China's chemical industry.

For this cooperation, Willy adopts the advanced technology from Germany - ultrafiltration + high pressure reverse osmosis + ultra-high pressure reverse osmosis +MVR process, which is based on the BIOMEMBRAT system developed by WWAG in Germany, and has been optimized and upgraded in combination with the actual domestic situation. With nearly two decades of technical accumulation and practical experience, Willy has continuously innovated on patented membrane system technologies and products, and has successfully completed more than 300 water treatment projects including ultrafiltration and reverse osmosis systems. In order to better cooperate with the production arrangement of the owner, Willy also pre-installed the membrane frame in the workshop, which greatly shortened the on-site construction period.

This cooperation between Wellie and Xiangfeng Industry marks another important progress in the field of phosphorus chemical wastewater treatment. Through the introduction of advanced water treatment technology, Willy will help Xiangfeng to further improve its environmental standards and achieve more efficient water recycling. This is an important step for Welly to get involved again in the field of advanced treatment, reuse and zero discharge of coal chemical wastewater after Hubei Shuanghuan, Hubei Xinyi Chemical Industry, Jiutai Energy Inner Mongolia Project, Hebei Xinxing Energy and other coal chemical wastewater treatment projects, and also the company's business expansion in the field of phosphorus chemical industry. Willy will continue to help domestic large chemical enterprises to achieve energy conservation and emission reduction targets, and promote the green and low-carbon transformation of the chemical industry.
