Energy-Efficient Water Treatment Systems for Industrial and Decentralized Applications

Dion+ delivers next-generation desalination 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 - To reduce costs and resource use, enabling off-grid, solar-powered desalination

Our Impact

Innovation

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.

High Efficiency

Core-innovative technologies for higher water recovery and lower energy use than conventional systems.

Sustainable

Minimal brine discharge and chemical free operation for reduced CO2 emissions and operating costs.

Modular

Dual architecture (MCDI + CCRO) for modular systems that are robust against widely varying salinities & contaminants

Decentralized

High energy efficiency enables systems to be fully integrated with photovoltaic (PV) for an off-grid & decentralized operation.

Our Services

We provide custom-tailored, high-performance and sustainable water solutions directly to the point of need, whether the application is urban, rural or industrial.

Design+

Custom engineering of MCDI systems to ensure optimal design tailored to meet the user’s specific water quality requirements and capacity needs - from electrode benchmarking to a holistic system evaluation.

Desalination+

Integration of next-generation water treatment technologies that combine energy efficiency, modularity, and digital intelligence for high-efficient, decentralized desalination.

Ongoing support for improved system operation of new or existing MCDI and CCRO systems, targeted maintenance and performance diagnosis to maximize efficiency throughout the system’s lifetime.
