In many industrial processes, such as electronics manufacturing, electroplating, chemical and other industries, wastewater containing perfluoroalkanes is generated. If these wastewater are discharged directly without treatment, it will cause serious pollution to the water environment. Ion exchange resins can be installed in wastewater treatment systems to effectively remove perfluoroalkanes from wastewater to meet discharge standards and avoid harm to the water environment.

For example, in the wastewater treatment plant of an electronic chip manufacturing company, a specially designed ion exchange resin system (internal PW735 resin) was used to reduce the concentration of typical perfluoroalkane contaminants such as perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS) in wastewater by more than 90%, ensuring that wastewater discharge meets local environmental regulations.

Ion exchange resin PW735 resin can operate stably under a wide range of temperature, pH and salinity conditions, and can adapt to the characteristics of complex matrices such as different industrial wastewater, soil eluents and groundwater, with good versatility and adaptability, which provides convenience for practical applications.
