Osmotically assisted reverse osmosis (OARO) has shown great potential for low-cost and energy-efficient brine management. However, its performance can be significantly limited by membrane fouling. Here, we performed the first time a comprehensive study on OARO fouling, explored associated fouling mechanisms, evaluated reversibility via simple physical cleaning strategies. First, internal at draw (permeate) side was to insignificant. Flux behavior in short-term operation correlated both...
Batch pressure-retarded osmosis (PRO) with varied-pressure and multiple-cycle operation using a pressurized variable-volume tank has been proposed as high-efficiency osmotic energy harvesting technology, but it suffers scalability constraints. In this study, more scalable batch PRO, namely, atmospheric PRO (AB-PRO), was proposed, utilizing an to receive store the intermediate diluted draw solution (DS) pressure exchanger recover from DS before being recycled into tank. Its performance...
