Telwesa is a pioneer company in the reuse of regenerated membranes for landfill leachate treatment. The company began its operations when Ecomemb was still a research project, over seven years ago.

Jordi Gabarro Bartual, PhD, Managing Director of TELWESA, participated in the roundtable discussion at the conference held on June 18 on Circular Management of Water Treatment Membranes, within the framework of the OSMO4LIVES project (LEQUIA, University of Girona). Here are his key messages:

Here are his key messages:

• Telwesa was the first industrial company to trust the use of regenerated membranes for leachate treatment
• The company conducted an internal validation through two years of operation, observing that there is no difference in quality or performance compared to other membranes.
• Since then, they have extended the use of regenerated reverse osmosis membranes for leachate treatment operated by Telwesa and have begun their installation for water reuse applications in other industries.
• All partner companies that test regenerated membranes repeat their use because clients verify that they obtain the same water quality at significantly lower costs compared to using new membranes.

Opinion of Guillem Gilabert-Oriol (R&D in water treatment) from the company DuPont Water Solutions : A set of solutions must be applied to drive membrane technology towards the circular economy.

Guillem Gilabert-Oriol (R&D in water treatment) from the company DuPont Water Solutions , one of the largest membrane manufacturers, participated in the round table of the conference held on June 18, 2025 on Circular Management of Membranes for Water Treatment, within the framework of the OSMO4LIVES project ( LEQUIA, University of Girona ).

His key messages were:

• DuPont focuses on minimizing the carbon footprint of membranes by producing durable, compact membranes with lower energy consumption and higher permeate quality.
• They work on predictive tools using operational data that help the user identify membrane fouling problems (Operations Advisor https://lnkd.in/dMzGXjut ).
• From Guillem’s point of view, in membrane technology, circularity involves a set of solutions: production of more efficient membranes, reconditioning and recycling.
• Concentrate valorization: new applications for membranes with the aim of recovering valuable compounds.

Access our technical brochure and you will see numerous comparative examples between the simulation performed by our expert staff and the deviation from start-up.
These are industrial cases with different configurations, number of installed membranes and operating conditions.

We have an almost immediate availability of already recovered Ecomembranes, always with a price range much lower than new membranes, while maintaining very similar performance to the originals.

In the technical brochure you will have access to success stories of Ecomembranes in Industry.

Part of our work consists of guaranteeing the maximum performance of the membranes with all guarantees. We extend the useful life of the membranes and accurately predict the water quality you will obtain before installing them. You will know what will be produced in your plant and under what conditions.

Having detailed information on each of the membranes that will be installed in a reverse osmosis plant, we can make very accurate projections. In other words, you will know what will happen before it happens!

We propose a configuration and operating regime for each installation and carry out parameter validation at start-up. Deviations in permeate conductivity between the projection and the results obtained at start-up are less than 5%.

And not only the quality, you will also have the operating conditions of your plant in advance. We have the permeability of each Ecomembrane, which will allow you to know what pressure the booster pump will have before installation.

The results speak for us! Contact us and check your options.
