Industrial wastewater distillation

With the continuous acceleration of domestic industrialization and urbanization, the problem of industrial pollution has become increasingly serious. Substandard discharge of wastewater during industrial production has seriously damaged the natural water resources system. Therefore, solving water resource pollution and returning water quality to purity are issues we continue to face and urgently need to be solved. With the development of materials and processes, membrane distillation has gradually become one of the solutions for wastewater treatment, especially high-concentration refractory wastewater treatment.

Case description

Industrial wastewater distillation

With the continuous acceleration of domestic industrialization and urbanization, the problem of industrial pollution has become increasingly serious. Substandard discharge of wastewater during industrial production has seriously damaged the natural water resources system. Therefore, solving water resource pollution and returning water quality to purity are issues we continue to face and urgently need to be solved. With the development of materials and processes, membrane distillation has gradually become one of the solutions for wastewater treatment, especially high-concentration refractory wastewater treatment.

Sci-Nano PTFE membrane distillation technology mainly uses PTFE hydrophobic hollow fiber membrane as the separation interface, and uses the vapor pressure difference between the inside and outside of the membrane as the driving force for mass transfer. During the membrane distillation process of non-volatile aqueous solutions, it is ensured that only water vapor can pass through. Through the membrane pores, ions, macromolecules, colloids, cells and other non-volatile substances are trapped, so water quality similar to distilled water can be directly obtained. The PTFE hollow fiber membrane used in the Sci-Nano membrane distillation module has the characteristics of strong hydrophobicity, strong chemical stability, high porosity, high mechanical strength, and long service life. It can effectively avoid the hydrophilicity of the membrane fiber after long-term operation. Liquid infiltration, interface damage and other phenomena caused by chemical changes are eliminated to ensure the service life of the membrane module.
