Membrane Distillation Components


‌Membrane Distillation Components




Working Principle: Membrane distillation is a separation and concentration technology that utilizes the vapor pressure difference between the feed and permeate sides of a hydrophobic membrane (dependent on temperature) as the driving force for substance separation and filtration. The PTFE-MD-2020 membrane component features hollow fiber membranes that effectively remove volatile components from aqueous solutions, making it widely applicable for water distillation and seawater desalination.





Characteristics of Membrane Distillation Components




High Hydrophobicity: PTFE material offers excellent hydrophobic properties, effectively preventing moisture from passing through the membrane.

Chemical Stability: Resistant to acids and bases, suitable for various chemical environments, ensuring long-term stable operation.

High Separation Efficiency: Uniform pores with a narrow pore size distribution significantly enhance separation efficiency.

No Chemical Leaching: Ideal for food and beverage industries, it produces no chemical leachates.

Optimized Design: Designed to avoid concentration polarization and scaling, improving system efficiency.

Modular Design: Compact installation footprint simplifies the construction process.

Energy Efficient Recovery: The system utilizes heat energy progressively, ensuring efficient use of the driving heat source.

Low-Temperature Operation: Capable of utilizing various low-grade waste heat sources (e.g., hot water, steam, solar energy) to enhance energy efficiency.

All-Plastic Material: The equipment offers excellent corrosion resistance, low cost, and long service life.
