Pervaporation

Advanced Membrane Separation for Resource Recovery

Pervaporation is an advanced membrane separation technology that enables the selective permeation of a diffusive component from aqueous-organic mixtures. This process is primarily used to remove solvents from mixtures, resulting in a concentrated feed stream and a purified solvent stream. Pervaporation is highly effective for resource recovery and waste valorization in industrial applications, particularly in water and wastewater treatment systems.

Advantages of Pervaporation

Pervaporation offers significant advantages over conventional separation technologies:

Energy-Efficient: Reduces energy consumption compared to traditional separation methods.
Sustainable: Promotes environmentally friendly operations with minimal waste generation.
Cost-Effective: Offers a lower total cost of ownership with reduced operating and maintenance costs.
Selective Separation: Provides high selectivity for solvent separation from mixtures, ensuring high-purity output.
How Pervaporation Works
The pervaporation process utilizes a dense polymeric membrane layer, which can be functionalized with either hydrophilic or organophilic properties. These membranes facilitate physico-chemical separation and mass transport of molecules through the membrane.
To achieve the desired separation, a vacuum or partial vacuum is applied to one side of the membrane. The solvent-selective membrane allows the preferential diffusion of solvent molecules while rejecting non-selective components from the feed mixture, ensuring an efficient separation process.

Applications of Pervaporation

Pervaporation is highly versatile and can be applied in various industrial sectors, including:

Solvent Recovery: For the recovery of valuable solvents from waste streams.
Ethanol-Water Separation: Separation of ethanol from water, often used in the distillation industry.
Pharmaceutical & Biotech Product Purification: Separation and purification of complex pharmaceutical or biotech streams.
Organic-Aqueous Selective Separation: Removal of organic components from aqueous mixtures.
Separation of Organic Mixtures: Efficient separation of organic compounds from complex mixtures.
Effluent Treatment & Zero Liquid Discharge (ZLD): Used for wastewater treatment and achieving ZLD systems.
Brine Minimization: Reducing brine volume in desalination and industrial wastewater systems.
Concentration of Aqueous Streams: Concentrating aqueous streams in various industrial processes.
