BlueNexus Technologies
The technology arm of GreenTech, building modular, AI-operated water plants for industrial and municipal use — i-WaterHub™ and the AquaX Robot™ operating layer.
The plant is one part. Darcarion covers the rest. Site survey and water characterisation come first, then the civil and structural works, the utilities tie-in, and any additional process or polishing stages a specification demands above the standard configuration. Project management, authority submissions and documentation are ours, so delivery stays on one schedule and one point of contact. And it does not end at handover — commissioning support, operator training, spares and chemicals, and long-term operation and maintenance all sit with the same team.
bluenexus.tech ↗i-WaterHub™ A plant that arrives finished
A conventional plant is a construction project — civil works first, equipment after, commissioning last, and every problem found on site. This inverts that. Equipment, controls, pipework, structure and buildings are integrated into 40-foot modular units, built on a factory assembly line, then commissioned and trial-operated before they ship. On site the work reduces to assembly and connection.
Delivery is measured in weeks rather than the seasons a conventional build takes — which changes what is possible when a project is waiting on water. BlueNexus reports up to 90% less footprint than a conventional equivalent.
| Series | Source water | Process | Capacity | Footprint |
|---|---|---|---|---|
| UF | Surface water | Ultrafiltration | 3,500 – 10,500 m³/d | 146 – 239 m² |
| UR | WWTP effluent, surface water | UF and reverse osmosis | 2,500 – 10,000 m³/d | 192 – 568 m² |
| BW | Brackish water | Brackish reverse osmosis | 2,500 – 10,000 m³/d | 192 – 568 m² |
| SW | Seawater | Single or dual stage desalination | 2,500 – 5,000 m³/d | 285 – 565 m² |



AquaX Robot™ An operator, not a dashboard
AquaX Robot runs the plant rather than reporting on it — analysing, deciding and executing, instead of raising alarms for somebody else to action. Computer vision, acoustic and infrared sensing give it real-time awareness of plant condition, working alongside process optimisation models and predictive maintenance on both equipment and process. Relevant anywhere certified operators are hard to find and harder to keep.
At the partner's own service centre, a distributed unmanned operating model let ten staff run the operation. BlueNexus reports reductions of 90% in labour, 50% in equipment failure rate, 30% in electricity, 15% in chemical cost and 35% in overall operating cost.
