Product Description

Membrane Distillation Contactors(PTFE-MD)

Membrane distillation is a process based on membrane separation/concentration technology that uses the vapor pressure difference (depending on temperature) between the feed and permeate sides of a hydrophobic membrane as a driving force to achieve separation and filtration of substances.
SCI-NANO membrane distillation module MD-2020 uses PTFE hollow fiber membrane filaments with high hydrophobicity, high melting point and excellent chemical stability and corrosion resistance. It can effectively remove volatile components in aqueous solutions and is suitable for water distillation and Desalination treatment. Compared with traditional distillation technology, the advantages of membrane distillation are that it can use low-grade and economical heat sources, occupy smaller land area, and reduce investment costs.

Features and advantages of PTFE membrane：

· The system has high separation efficiency and can handle high-concentration liquids.

· Operating at near-normal pressure saves over 80% ofenergyconsumption and fully utilizes waste heat to create costadvantages.

· The treatment effect is stable, allowing for direct effluentreuse and achieving zero discharge.

· The system is stable, easy to operate, and has a long servicelife.
