Membrane Distillation: A Niche Application for Wastewater |Biomedgrid

The sought-after efficient treatment of wastewater has become an essential purpose. in this context, Membrane Distillation (MD), which is a thermal-based membrane technology, has the ability to treat wide range of wastewater streams such as industrial wastewater, seawater, brine water from other processes, and oil-gas field produced water. MD membranes are basically hydrophobic in nature so they are susceptible to fast wetting and severe fouling. In this mini review recent efforts in using MD for treating wastewater treatment will be mentioned briefly, along with novel membranes with special anti-wetting features to overcome the trade-off between permeability and selectivity.
