Industrial Plant / Pervaporation Units
THE RIGHT TECHNOLOGY FOR YOUR DEHYDRATION PROCESS
Our compact pervaporation skids process liquid feeds directly, without the need for energy-intensive evaporation. This significantly reduces energy consumption compared with conventional distillation.

Efficiency without compromise
Our pervaporation process treats the feed directly in the liquid phase, eliminating the need to evaporate the entire stream beforehand. The result is significantly lower energy consumption.
A key advantage is operational flexibility. Our systems respond dynamically to changes in feed composition. Whether the water content or the chemical composition varies, our membranes allow for quick adjustment of operating parameters. Working closely with you, we develop a tailored configuration that delivers consistently high product purity, even when upstream process conditions fluctuate.
Scalable solutions
We offer the right system for every requirement. Our portfolio includes both highly specific custom plants and cost-effective standard solutions:
- Standardised batch plants: We have developed a standardised system for capacities of up to 5,000 litres of wet solvent per day.
- Continuous industrial systems: For higher throughput, we provide units with flow rates ranging from a few litres per hour up to 4,000 litres per hour.
- Straightforward integration: Our skids can be supplied as fully turnkey systems, including automation, or prepared for integration into your existing control system. In close collaboration with your team, we develop a solution that integrates seamlessly into your infrastructure and process.
Broad chemical compatibility
Our pervaporation membrane units are suitable for a wide range of chemical systems, including:
- Alcohols: ethanol, isopropanol (IPA), n-Propanol, sec-Butanol
- Specialty chemicals: acetonitrile, tetrahydrofuran (THF), acetone, acrylonitrile
- Esters and borates: methyl acetate, ethyl acetate, trimethyl borate
- Specialty solvents: cyclopentanone, methyl-THF
Built for long-term performance
Long service life is essential for economic operation. DeltaMem systems are designed for a service life of more than 20 years, with exceptionally robust membrane modules at their core. While the average membrane lifetime in the market is often considerably shorter, our membranes typically operate for more than four years. In some customer applications, the same membrane sets have been operating for up to twelve years without any loss of performance.
We support you throughout membrane module replacement and ensure, through our quality control, that your plant continues to deliver optimum performance and selectivity throughout its service life.

Frequently asked questions
Why choose pervaporation over vapour permeation?
Pervaporation treats liquid streams directly, eliminating the need to evaporate the entire feed – a requirement of vapour permeation. This significantly reduces energy consumption and enables a more compact plant design.
Does DeltaMem provide automation as part of its systems?
Yes. We supply turnkey process plants including automation, programming and commissioning. Alternatively, if you prefer to manage automation in-house, we provide detailed functional specifications to ensure seamless integration into your existing control system.
How do DeltaMem pervaporation plants perform when feed conditions vary?
Our systems are designed to maintain stable operation, even when feed composition changes. By continuously monitoring process data, DeltaMem systems automatically adjust operating parameters to ensure consistent product quality.
What maintenance do pervaporation systems require?
DeltaMem systems require minimal maintenance. Our specialists support the replacement of membrane module installation and carry out regular performance assessments to maximize membrane service life and ensure consistent system performance.
