Lab Technician Intern

At Ilion Water Technology, a watertech spin-off from the École Normale Supérieure (ENS) in Paris, we are developing an innovative pressure-free reverse osmosis technology, stemming from our nanofluidics research work.

Our technology, currently under development, has already been recognized with several distinctions, notably:

• Winner of the Innovation Award at Pollutec Paris 2024;

• Finalist of the Miriam Balaban competition, organized by the European Desalination Society 2025;

• Currently in the running for the international desalination competition XPRIZE.

We are confident that our approach can simplify the operating conditions of reverse osmosis skids and significantly reduce their cost and environmental impact. Indeed, our pressure-free technology has anti-fouling properties aimed at decreasing energy consumption and the need for chemical products. It also integrates a system for real-time water quality monitoring.
