“…The energy consumption in the RO system determines the cost of freshwater production, so the PAT is used to recycle the high-pressure energy of the concentrated brine before membrane. The pressure and capacity of seawater passing through the RO membrane are susceptible to the influence of season, weather and temperature, the pressure and capacity of recoverable high-pressure concentrated brine are also variable, which means that the energy recovery PAT will operate at different flow rate conditions with about 55 bar pressure [6]. Therefore, it is very important to design a PAT with high-efficiency range which can suit for the complex flow and multiple operating conditions.…”

The clean water and energy are both the most important needs of mankind. The increasing population and the necessity to meet the need for freshwater requirements make the desalination process a popular topic. The reverse osmosis is one of the most popular technique for desalination. The main advantages of the reverse osmosis over other desalination techniques are the lower energy consumption and the robustness to the salinity of feedwater. The ambient conditions are the key parameters affecting the efficiency of desalination process. On the other hand, the design parameters of a reverse osmosis desalination plant also play an important role in the process. In this paper, both ambient conditions and the design parameters are investigated. The contributions of the study are to determine variation the specific power consumption and related total power requirement of single stage reverse osmosis desalination plant model with the ambient conditions and design parameters. The effects of design parameters and ambient conditions for power requirements are given in the results section. The simulation studies are performed at constant production rate in order to see the effects of each parameter to product properties. The increase in seawater temperature for constant seawater salinity decreases the power consumption while increasing the salinity of final product. The results indicated that design parameters should be optimized according to the size of the designed system and salinity of feedwater. Also, a case study is performed for a point at Marmara Region, Turkey.

“…Thomson et al postulated that batteries can cause issues, especially in hot weather conditions, which may cause loss of energy of up to 25% [22]. The flow/pressure stabilizer is a hydropneumatic tank which can be used to dampen the excessive fluctuations in the energy supply to the pump and maintain steady flow of the feed water for desalination [23]. This system was made for brackish water with a salinity of 2500 mg/L and therefore, for pressures of 70 -105 psi.…”

Due to water scarcity and the global trends in climate change, winning drinking water through desalination is increasingly becoming an option, especially using reverse osmosis (RO) membrane technology. Operating a reverse osmosis desalination plant is associated with several expenses and energy consumption that take a very large share. Several studies have shown that wind power incurs lower energy costs compared to other renewable energy sources, therefore, should be the first choice to be coupled to an RO desalination system to clean water using sustainable energy. Therefore, in this paper, we investigate the feasibility of driving an RO desalination system using wind power with and without pressure vessel energy storage and small scale energy recovery using Clark pump based on simulation models. The performance of both variants was compared with several scenarios of wind patterns. As expected buffering and energy recovery delivered higher water production and better water quality demonstrating the importance of an energy storage/recovery system for a wind-power-supplied desalination plant.
