Hole-Type Spacers for More Stable Shale Gas-Produced Water Treatment by Forward Osmosis

Membranes, 2021
An appropriate spacer design helps in minimizing membrane fouling which remains the major obstacle in forward osmosis (FO) systems. In the present study, the performance of a hole-type spacer (having holes at the filament intersections) was evaluated in ...
