Separation Technologies

The world’s largest RO desalination plant in Abu Dhabi, UAE

Membrane-based dehumidification and desalination technologies use selective permeability to efficiently remove moisture from air and salts from water. Dehumidification enhances energy efficiency in HVAC systems, while desalination provides clean water for industrial and human use. Cryogenic distillation cools gases to low temperatures, separating them by boiling points to produce high-purity gases like O2 and N2. These technologies offer solutions for resource management in water treatment, air conditioning, and gas production.

We are interested in research on,

Membrane dehumidification using vacuum & liquid desiccant
Batch counter flow reverse osmosis & membrane distillation
Cryogenic distillation, pressure swing adsorption, & membrane separation
