While the multiplication of droughts reminds us more than ever of the importance of water management, solutions are emerging to recover and filter polluted water from major construction sites. From the Val-d’Oise, the company Rellumix, which specializes in the manufacture of filtration systems for industrial purposes, has developed a technology for treating water from works.
On the Grand Paris Express worksites and in the nuclear facilities, the treatment of waste water is becoming central for large companies in the face of tougher regulations. Established in Cergy since 2007, the SME, which has achieved a turnover of more than 5 million euros with 30 employees, is increasingly called upon to help them in this process.
Although its activities are mainly focused on the aeronautics sector, an area in which Rellumix has built its expertise with giants such as Safran and Naval Group, the company has made a strategic shift in the face of the explosion in wastewater treatment needs. In this sense, the company received an envelope of 800,000 euros from the recovery plan in 2020 to invest massively in the deployment of its technology. And the company has put an additional 400,000 euros out of its pocket.
“We have developed a machine that filters and rejects water instantly in a natural environment such as the Seine”, explains Frédérick Dombrowski, the president of Rellumix. Its machines are already deployed on certain Ile-de-France sites. And thanks to its technology developed 4 years ago, the SME is struggling to honor all requests. “It can be positioned on any type of non-drinking water work, we have a huge market opening up before us,” observes the manager.
Rellumix is also working on a new solution, in collaboration with the school of industrial biology (EBI) of Cergy, in order to treat all the viruses and bacteria present in the water. Countries such as the Democratic Republic of Congo are already interested in this type of solution to treat stagnant water and reuse it without the risk of malaria contamination.
Although the company has a popular product and particularly significant market opportunities, it is struggling to attract new profiles. While the leader believes he can triple his turnover, he will favor external growth. “I’m looking to buy a company already positioned on the water because it’s complicated to recruit today, either the profiles don’t match, or they don’t stay,” laments the manager. No less than 20 people are wanted.
For several months he has been actively prospecting to take over a company in Val-d’Oise, Eure or Oise, but does not close the door to further development in France in the event of failure.
