Brine management is a major bottleneck for coal seam gas (CSG) production in Australia. This study investigated the concentration of CSG reverse osmosis (RO) brine using a pilot membrane distillation (MD). The system was equipped with a novel spiral-wound air gap membrane distillation (AGMD) module.

A technique to optimise thermal efficiency using brine recycling during direct contact membrane distillation (DCMD) of seawater was investigated. By returning the hot brine to the feed tank, the system water recovery could be increased and the sensible heat of the hot brine was recovered to improve t

• Life cycle assessment of engineered osmosis and osmotic dilution are performed • Environmental impacts of forward osmosis can be competitive with deep well disposal • The cost of FO can be significantly lower (up to 60%) than deep well disposal • FO energy demand with no upstream pretreatment is a

• Highly impaired liquid streams can be sustainably treated by forward osmosis. • Forward osmosis treatment of drilling mud and produced water was evaluated. • Water recovery N 70% was achieved in pilot and demonstration scales. Forward osmosis is a suitable and effective process for treatment of di

A novel osmotic membrane bioreactor (OsMBR) is presented. The system utilizes a submerged forward osmosis (FO) membrane module inside a bioreactor. Through osmosis, water is transported from the mixed liquor across a semi-permeable membrane, and into a draw solution (DS) with a higher osmotic pressu
