A significant proportion of potable water for rural communities is produced from brackish water
sources by localised reverse osmosis (RO) operations. However, these inland RO plants typically
recover only 70-75% of the feed water, the remaining 25-30% of the resource being discarded as
saline RO concentrate. One possible remedy to this situation is to increase water recovery by passing
the RO concentrate through an additional process like membrane distillation (MD).
