This compact, water purification device removes salt and harmful ions (such as heavy metals, fluorides and arsenics from brackish water using electrostatic force (technology called capacitive deionization, CDI). Ideal for off-grid and disaster-prone regions, it supports safe drinking water supply with minimal energy consumption and no chemical additives.

Designed for use by NGOs, local governments, and international organizations, it enables self-sufficient water access in remote or emergency settings.

• Energy-efficient operation: 100–300 watts per hour, significantly lower than traditional RO systems
• High water recovery rate: 50%–90%, producing 1–2 m³ per day (approximately 1–1.5 liters per minute)
• Low maintenance cost: No need for expensive membrane replacements
• Portable design: Lightweight and compact for easy field deployment

This CDI-based desalination unit presents a scalable, low-cost solution for communities facing water scarcity, humanitarian emergencies, or lacking infrastructure for safe drinking water. Its energy efficiency and mobility make it ideal for deployment in both urban peripheries and off-grid environments.

With proven field deployments and accolades from CES and the UNESCO, the system has demonstrated at Kenya, (Naivasha Water & Sanitation Co.). The solution is highly competitive due to its portability, ease of use, and compatibility with international aid and development frameworks CES and the UNESCO, the system has demonstrated at Kenya, (Naivasha Water & Sanitation Co.).

This portable desalination device offers a practical and scalable solution to a range of environmental and humanitarian challenges related to water scarcity. Its compact design and energy-efficient performance make it ideal for deployment in:

• Coastal regions affected by saline groundwater or contaminated water sources
• Conflict or disaster zones requiring emergency access to clean drinking water
• Remote or rural areas with limited transportation infrastructure

• CDI companies which may be interested in ‘compact size and hands on’ CDI unit (e.g Voltea in Netherlands, ORAIPL in India)
• NGO, Humanitarian Foundations, Institutes, Funds, Initiatives etc. which may be interested in addressing water problem in undeveloped countries by applying ‘compact size hands-on CDI unit’ (e.g. GivePower Project in Kenya)
