Forward osmosis

• CHP–H2CO3 is a high osmotic pressure thermolytic draw solute. • CHP–H2CO3 solutions produce relatively high forward osmosis water fluxes. • Low grade heat should be sufficient to degas CHP–H2CO3 solutions. • CHP–H2CO3 solutions display good material/membrane compatibility. • Water flux and reverse dr

Forward osmosis (FO) has recently attracted growing attention in wastewater, brackish groundwater and seawater desalination, and power generation. This study evaluates the potential of using a batch laboratory-scale FO system as a pre-treatment for the reverse osmosis (RO) process. FO is a low press

• 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

Forward osmosis is a rapidly emerging technology that has potential to enable low cost water treatment and desalination. Previous investigations have found that reverse osmosis (RO) membranes were unsuitable for forward osmosis in part due to their hydrophobic support layers, which inhibit wetting.

The present study evaluated the performance of pressure retarded osmosis–reverse osmosis (PRO–RO) process for power generation and seawater desalination. Two pre-developed software were used separately to estimate the performance of forward osmosis (FO) and RO process. The draw and feed solutions in

Hypersaline solution with high TDS is not suitable for direct treatment by the conventional membrane and thermal processes. The current study proposes a dual-stage FO/PRO process for hypersaline solution treatment and power generation. The treatment process reduces the concentration of saline wastew

In this paper, the viability of using micellar draw solutions (DS) for Forward Osmosis (FO) is presented for the first time. Above the critical micelle concentration (CMC) and the Krafft temperature (Tk), the monomers in a surfactant solution aggregate to form micelles, resulting in a relatively cons

New membranes for forward osmosis (FO) have been made by numerous academic groups around the world. Few of these designs, however, have made it to full-scale production. For two decades, the only FO membrane made on a full-scale production line was a cellulose acetate membrane from Hydration Technol

Forward Osmosis (FO) has many applications in water and wastewater treatment and seawater desalination. In this paper, the FO was suggested for seawater pretreatment to the thermal desalination processes such as Multi Stage Flashing (MSF). The integrated FO–MSF hybrid system was designed to reduce t

In the last decade osmotically driven membrane processes have attracted growing interest in wastewater treatment, desalination and power generation. A hybrid forward osmosis–nanofiltration (FO–NF) system designed for brackish water desalination was systematically investigated in this study. The hybri
