Next-generation desalination
We are a cleantech startup developing sustainable, efficient and cost‑effective desalination and water‑treatment solutions for a climate-resilient future.
Energy-efficient water treatment systems for industrial and decentralized applications
Dion+ combines advanced deionization and reverse osmosis technologies with intelligent control to deliver high-efficiency & sustainable water solutions that drastically reduces energy use, brine discharge and operating costs.
Our custom, high‑performance systems bring sustainable water solutions directly to the point of need, whether the application is urban, rural or industrial.
Our Mission
At Dion+ our mission is to make sustainable, energy-efficient water treatment accessible worldwide through smart desalination technologies.
Our Vision
A world where every community and industry can rely on clean, efficient, and affordable water systems.
Bridging scientific innovation and practical solutions - Reducing costs and resource use & enabling off-grid, solar-powered desalination.
Our Impact
DION+ delivers fully integrated water treatment solutions based on membrane capacitive deionization (MCDI), optionally combined with closed circuit reverse osmosis (CCRO). Our systems are optimized for real-world operating conditions, enabling decentralized efficient desalination and selective ion removal with reduced energy demand and low-maintenance.
