“…Maximum power point tracking (MPPT) has been proposed recently to have real-time control of PRO systems by either controlling of only one parameter which is the pressure exerted [100][101][102] or simultaneously controlling of few parameters including feed flow rates, draw flow rates and pressure exerted [103]. Maximum net power and maximum specific energy can then be extracted from the PRO system at both the design stage and in the field with varying conditions [103]. Nevertheless, laboratory-scale studies are still in great need even though numerous simulation and model-based optimization studies [104][105][106] have been carried out.…”

“…The efficiency of the PRO process is reduced as a result of increased energy need for pumping even though increasing cross-flow rates leads to increased power densities [114]. In certain cases and up to certain limits, improvement in osmotic performance and power generation can justify the energy invested for additional pumping [103]. At the optimal cross-flow, a balance of pumping energy and osmotic performance shall be accomplished [96].…”

Factors Affecting the Performance of Membrane Osmotic Processes for Bioenergy Development

et al. 2020

Forward osmosis (FO) and pressure-retarded osmosis (PRO) have gained attention recently as potential processes to solve water and energy scarcity problems with advantages over pressure-driven membrane processes. These processes can be designed to produce bioenergy and clean water at the same time (i.e., wastewater treatment with power generation). Despite having significant technological advancement, these bioenergy processes are yet to be implemented in full scale and commercialized due to its relatively low performance. Hence, massive and extensive research has been carried out to evaluate the variables in FO and PRO processes such as osmotic membrane, feed solutions, draw solutions, and operating conditions in order to maximize the outcomes, which include water flux and power density. However, these research findings have not been summarized and properly reviewed. The key parts of this review are to discuss the factors influencing the performance of FO and PRO with respective resulting effects and to determine the research gaps in their optimization with the aim of further improving these bioenergy processes and commercializing them in various industrial applications.

“…The first MPPT research for PRO systems was conducted in 2015, considering dynamic changes, including incremental mass resistance (IMR) as well as perturbation and observation (P&O) methods [8]. Both algorithms have to find a balance between oscillations and the response time, resulting in greater power loss [9]. Studies have shown that the operational environment depends on specific circumstances, materials, and other constraints [10].…”

The analytical solutions of complex dynamic PRO systems pose challenges to ensuring that maximum power can be harvested in stable, rapid, and efficient ways in response to varying operational environments. In this paper, a boosted particle swarm optimization (BPSO) method with enhanced essential coefficients is proposed to enhance the exploration and exploitation stages in the optimization process. Moreover, several state-of-the-art techniques are utilized to evaluate the proposed BPSO of scaled-up PRO systems. The competitive results revealed that the proposed method improves power density by up to 88.9% in comparison with other algorithms, proving its ability to provide superior performance with complex and computationally intensive derivative problems. The analysis and comparison of the popular and recent metaheuristic methods in this study could provide a reference for the targeted selection method for different applications.

“…A lot of effort is being made in that direction: Wan et al developed membranes with one of the highest power densities [19], Nagy et al modelled fouling mechanisms and the effects on PRO [20], Long et al gave indications about energetically optimal operation strategies [21]. Control strategies have also been proposed [22], as well as different process configurations [23], even integration with other processes, such as desalination [9], [17]. Taking into account these achievements and the expected solution to the current challenges, PRO is deemed to be a viable option [14] to exploit SGE at the location presented in this research.…”

The Magdalena River mouth in Colombia is studied as a candidate site for a renewable power plant via osmotic energy technology, using pressure retarded osmosis. This power generation plant would operate through the controlled mix of two flows with different salinities (river water and sea water in this case study). A preliminary design of a pressure retarded osmosis power plant is proposed here by means of experimental data acquisition on-site at the river mouth. The obtained net power production is shown to reach 6 MW, with adequate membrane power densities above 5 W/m 2. These promising results consider energetic losses involved in the process, which have been further analysed to propose improvement targets in pretreatment processes and membrane permeability.
