Key observations on the reuse of regenerated reverse osmosis membranes in the chemical and mining industry:

• In the chemical industry, a comparative study of the behaviour of regenerated membranes versus new membranes is being carried out. In the 6 months they have been operating, similar flow rates are produced, at similar pressures and with similar water quality. Both types of membranes require identical cleaning and maintenance processes.
• In a mining industry installation with more than 1,500 membranes, a test is being carried out with one stage of a rack (one of seven). In the short term, the performance of the regenerated membranes is positive and the permeated water reaches the values required by the process.

Ignacio Sanguino, Technician at the Cogeneration and Services Plants of SAICA (Burgo de Ebro) presented the case study during the Conference on Circular Management of Membranes for Water Treatment, held on 18 June 2025 within the framework of the OSMO4LIVES project (LEQUIA, Universitat de Girona).

Key observations on the reuse of regenerated reverse osmosis membranes in the paper industry:

• The process values observed at start-up were similar to those committed by Ecomemb.
• The water treatment process continues to be reliable, guaranteeing over time the conditions required by the user, in a continuous 24h / 7 days a week operation.
• With the configuration we offer, the quantity and quality required by the process is shaped, producing more water with less energy than using new membranes, while meeting the quality requirements of the process.

Regeneration of your own reverse osmosis membranes for reuse. The golf course at La Pineda de Vila-Seca in Tarragona (Infinitum Resort) is one of the pioneers in Spain in regenerating its own membranes for reuse in wastewater regeneration for turf irrigation. This golf course started in 2021 with validation tests under research projects led by Dr. Raquel García Pacheco during her phase as a researcher in the LEQUIA group at UdG, today CEO of Ecomemb.

Tomás Agulló Rodenas, Golf course superintendent at INFINITUM, shares his experience on the regeneration of his own reverse osmosis membranes for reuse, at the round table held on 18 June 2025 as part of the Conference on Circular Management of Membranes for Water Treatment within the framework of the OSMO4LIVES project (LEQUIA, Universitat de Girona).

Key messages from Tomás Agulló Rodenas on the reuse success story:

• Infinitum has been collaborating with Ecomemb for more than two years to regenerate its own membranes and reuse them in the same process.

• Many of their membranes have an initial lifespan of 14 years.

• The implementation of their own regenerated membranes has not resulted in any operational change compared to replacing with new membranes: “They work as always, as before implementing regenerated membranes, with the same pressures, same flow rates, same cleanings and same issues”.

Regenerated Reverse Osmosis Membranes. ECOMEMB joins forces with the public company Ens d’Abastament d’Aigua Ter-Llobregat (ATL) to promote sustainable models for the use and management of reverse osmosis membranes.

The public company Abastecimiento de Agua Ter Llobregat (ATL), dedicated to the purification and distribution of drinking water in bulk to more than 5.5 million inhabitants in Barcelona and 10 other districts of the metropolitan area, is committed to the comprehensive sustainability of the reverse osmosis process, which includes efficient management of membranes at the end of their useful life for their particular process.

ATL supported the regenerated reverse osmosis membrane initiative from the outset through a collaboration agreement with the LEQUIA group at UdG. Since 2019, they have donated membranes to ongoing research projects in order to apply and validate regeneration protocols and subsequently validate the behaviour of regenerated membranes in industrial processes requiring high pressure.

Now that the alternative is already on the market, a strategic alliance has been established with Ecomemb to identify membranes suitable for regeneration and reuse in osmosis processes, thus minimising the disposal of membranes to landfill.

Partial text of the article Regenerated Reverse Osmosis Membranes. A Sustainable and
Circular Commitment published in the journal RETEMA (May-June 2025, pp. 186-187)

Likewise, Fernando Valero Cervera, Head of R&D&I and Process Control at ATL, during his participation in the round table at the Circular Management of Membranes for Water Treatment Conference held on 18 June 2025, within the framework of the OSMO4LIVES project (LEQUIA, Universitat de Girona), expressed his views on regenerated reverse osmosis membranes as a sustainable and circular commitment.

Key messages from Fernando Valero in his intervention:

• ATL has more than 25,000 reverse osmosis membranes installed in Catalonia between the IDAM del Prat and IDAM la Tordera and plans to increase its desalination capacity in the coming years.

• They have been collaborating with Ecomemb and the Universitat de Girona to extend the useful life of their membranes for several years.

• The fact that more efficient membranes can be obtained from manufacturers and that membranes can be regenerated and reused, in the same processes or in other industrial processes, is a major step forward.

The Government of Catalonia has recognized the talent and innovation of researchers and CERCA centers with the presentation of the 2024 National Research Awards, as announced last Friday, March 21st, by the Minister of Research and Universities, Núria Montserrat.

These awards seek to recognize research excellence in Catalonia across 7 categories, including the National Innovation Award for the Creation of a Science-Based Company, granted to Ecomemb. This award aims to stimulate the creation of science-based companies, acknowledge the importance of and promote the transfer of research results to society, as well as highlight the increase in socioeconomic potential and social welfare through the formation of companies born from research.

Ecomemb Wins 2024 National Innovation Award

The award recognizes the capacity of the Universitat de Girona (UdG) and ICRA the ability to transfer research in innovative solutions for water management and the circular economy to the market through its support for the creation of ECOMEMB. Ecomemb’s membrane regeneration processes are based on technology developed by the UdG’s LEQUIA research group in collaboration with ICRA through various R&D&I projects, which enabled the technology to be patented with the support of the Valorization and Transfer Unit of the Research and Technology Transfer Office (OITT) of both institutions.

It is estimated that more than 1.5 million of these membranes are discarded worldwide each year (equivalent to 25,500 tons of plastic annually), even though around 70% could be refurbished to extend their lifespan. Ecomemb was created to minimize this problem.

Founded in December 2022, Ecomemb S.L. is the first European company specializing in the regeneration of reverse osmosis membranes for reuse in the same processes for which they were designed.

Ecomemb’s technology allows it to regenerate these membranes while minimizing the resources required and maximizing process efficiency. Regenerated membranes have up to 270 times less CO2-e emissions compared to producing a new membrane and consuming fossil resources for its production. Thus, Ecomemb works to positively impact the environmental sustainability and circular economy of industrial water treatment.

The use of Ecomemb® membranes allows:

• Save up to 60% on membrane replacement costs.
• Use less energy in filtration while maintaining the same water quality standards.
• Extending the membrane’s lifespan (in most cases, the second life is equal to the first)
• Avoid the emission of 95 kg of CO2e into the atmosphere and the generation of 15 kg of plastic waste for each regenerated membrane.

Jornada sobre la gestió circular de membranes per al tractament d‟aigua

L'entrada ECOMEMB Wins 2024 National Innovation Award from the Government of Catalonia as a Science-Based Company ha aparegut primer a REVERSE OSMOSIS MEMBRANES REGENERATION .

Workshop on the circular management of membranes for water treatment. The event, held on June 18, was organized by the LEQUIA de la Universitat de Girona and the spinoff Ecomemb.

The increase in desalination plants worldwide has put the focus on the management of one of their waste products: reverse osmosis membranes. These membranes are made of filtering plastic material that, once they reach the end of their useful life, are deposited in landfills or incinerated. It is expected that by 2025 the quantity will rise to more than one and a half million membranes.

The conference organized by the LEQUIA research group of the University of Girona (UdG) and the company Ecomemb S.L disseminated technological and management solutions to address this challenge. Focused on the results of the UdG’s Osmo4Lives project (2022-2025), it also brought together researchers from other entities and the different actors involved in the manufacture, use and management of osmotic membranes for water treatment. The event took place on June 18 at the UdG Research and Innovation Hub.

The program

The program was structured in three blocks. In the first, the latest technological advances in membrane regeneration and reuse were presented.

• Gaëtan Blandin and Bianca Zappulla (LEQUIA, University of Girona) summarized the advances in membrane regeneration through physicochemical treatments achieved with the OsmoLives project.
• Mohamed Khayet (Complutense University of Madrid and IMDEA Agua) detailed the results of different previous national and European projects in this same field.
• Jorge Senán-Salinas (BETA, University of Vic) spoke about the reduction of environmental impacts achieved with regeneration and its quantification through life cycle analysis.
• Zulema Rojas from Sorigué presented the results of an innovation project to recycle discarded membranes as fuel.

In the second block, several industrial experiences of regeneration and reuse of regenerated membranes were presented.

• Raquel García-Pacheco explained the success story of Ecomemb, the spinoff of UdG and the Catalan Water Research Institute (ICRA). Ecomemb is the first European company specialized in the regeneration of reverse osmosis membranes for reuse at the original facilities or by third parties.
• Nicolás Urgoiti (EMASA) presented a reuse experience at the same original facility, using 80 of their own membranes regenerated by Ecomemb and validated for reuse at the ETAP Atabal water treatment plant.
• Ignacio Sanguino (SAICA) spoke about the successful reuse of more than 100 regenerated membranes in the paper industry (different origin from the first useful life of the membranes).
• Nacho Palacios (Agua e Industria) compared the use of new membranes and regenerated membranes in water treatment plants in the chemical sector and mining.

Finally, a round table moderated by Xavier Guillem (Ecomemb) brought together representatives from membrane manufacturing companies (Guillem Gilabert-Oriol, Dupont); suppliers of discarded membranes from desalination plants (Fernando Valero, ATL); and companies using regenerated membranes (Jordi Gabarró from TELWESA and Tomàs Agulló from Infinitum).

The exchange of knowledge and experiences highlighted the need to adopt multiple strategies and technological solutions to manage reverse osmosis membranes by applying the principles of sustainability and circular economy. It also evidenced the need for collaboration between manufacturers, users, regenerating companies and academic institutions.

Technology transfer success story

The organizers – researcher Gaëtan Blandin from the LEQUIA group at the University of Girona and Ecomemb S.L. CEO Raquel García Pacheco – valued very positively the interest generated by the conference, with more than 70 people, mostly from companies and entities in the water sector. In this regard, Silvia Simón (delegate of the UdG rector for promotion and dissemination), Claudia Fontàs (director of the UdG Water Campus) and Marilós Balaguer (director of LEQUIA) highlighted the successful transfer of membrane regeneration technology that has resulted in the creation of Ecomemb S.L., recently recognized by the National Innovation Award of the Catalan Foundation for Research and Innovation.
