Recently, the industrial application test of Tianjin Petrochemical's phosphorus-free water treatment scheme was successful, and the phosphorus content in the external drainage was less than 0.4 mg / liter, which reached the national standard. This article is reproduced and shared by Shanghai Wuyue Pump and Valve Manufacturing Co., Ltd. Shanghai Wuyue is a professional safety valve manufacturer . It mainly produces all kinds of spring full-opening safety valves , spring micro- opening safety valves , and provides related product technical support for users for life. .
In order to protect the heat exchange equipment, in the process of circulating water treatment, the company usually adopts a mature process of adding a formulation containing phosphorus, and the state has strict regulations on the phosphorus content of external drainage. Almost half of Tianjin's petrochemical industry's water use is desalinated seawater. They must not only implement strict local standards, but also solve the problem of strong corrosion of equipment by desalinated seawater.
Earlier this year, Tianjin Petrochemical started the industrial application of the circulating water phosphorus-free water treatment scheme, and repeatedly carried out the trial of the phosphorus-free agent dosing scheme. After 4 months of research and testing, Tianjin Petrochemical has achieved a breakthrough in circulating water treatment from the use of high-phosphorus agents to low-phosphorus agents to non-phosphorus agents. The external drainage indicators fully meet the country's most stringent requirements.
