Abstract:

Reverse osmosis (RO) membranes have been used for seawater desalination and freshwater supply for long time. Nowadays, RO is considered to be the most efficient technology for seawater desalination and has the highest number of installations worldwide. Despite the high performance and reliability of RO technology in saline water treatment, it is still considered expensive for many countries. Average power consumption in RO technology is between 3 kWh/m3 and 4 kWh/m3. Recently, Forward Osmosis (FO) process has been suggested for seawater. FO hybrid system consists of FO pretreatment and RO regeneration process which has the potential of improving the performance of conventional RO system. The FO power consumption is negligible because it employs natural osmosis for freshwater extraction from seawater. Most power consumption in FO-RO process is due to the energy requirements in the RO regeneration system. Several studies have investigated the feasibility of FO process and the system energy efficiency compared to RO system. Unfortunately, there are limited data available about the performance of FO process in field carried out by Modern Water Company. Pilot plant studies demonstrated that FO pretreatment can improve the performance of subsequent RO process significantly. The current study evaluates the performance of FO-RO system through investigating the impact of operating parameters on system power consumption and product water quality. Conventional RO performance has been evaluated under constant pressure and constant recovery rate using a number of seawater feed salinities. Pre-developed FO computational program and Reverse Osmosis System Analysis (ROSA) software have been used to estimate the performance of FO-RO and RO processes. The outcomes of current study can be considered to improve the performance of FO-RO system. Recent Publications 1.
