The project that our company cooperated with Ningxia Guanneng New Material Technology Co., Ltd. is located in Ningxia. According to the on-site planning and investment budget, the main method is to use raw water to make desalted water: multi-media + self-cleaning + UF + secondary RO + mixed bed, condensate treatment system: heat exchange + oil removal + iron removal + mixed bed process, reclaimed water reuse treatment system: first-level high density + first-level multi-media + first-level self-cleaning + first-level UF + first-level RO (concentrated water) + second-level high density + first-level advanced oxidation + second-level multi-media + second-level self-cleaning + second-level ultrafiltration + weak acid cation bed + decarbonization tower + second-level RO (concentrated water) + second-level advanced oxidation + third-level RO, with a scale of 300m³/h desalted water system, 400m³/h condensate treatment system, and 450m³/h reclaimed water reuse treatment system. With extremely low operating costs, it has won unanimous praise from the owners, responded to the national call for energy conservation and emission reduction, and made the greatest efforts for the national environmental protection cause.
