the ro and ed units are modeled on ees (f-chart-software, ees: engineering equation 2020 ) software with the built-in seawater fluid package. the thermodynamic balances are applied, and the efficiencies of the overall system and individual units are calculated.
the system shown in figure 1 is mathematically modeled on engineering equation solver (ees) (f-chart-software, ees: engineering equation 2020 ) software by analyzing each unit. the thermodynamic balance equations used in the model are presented in . the ed and ro systems are modeled by utilizing simple equations without detailed membrane calculations to carry out the thermodynamic analysis. the solar pond is simulated based on a model provided by khalilian et al.

the sensitivity analysis is performed to see how changes in pressure, temperature, salinity, and solar irradiance affect the energy and exergy efficiencies of the system. the final sensitivity analysis results are summarized in tables 3, 5, 6, and 7. typically the system has much higher energy efficiency when higher temperatures are used in the evaporator to increase the osmotic pressure. therefore, to achieve higher energy efficiency a lower salinity is required in the evaporator to decrease the osmotic pressure. on the other hand, using high pressure in the evaporator is less effective in producing higher levels of osmotic pressure. this leads to increased salinity requirement in the turbine in order to create the high pressure in the evaporator. furthermore, when higher solar irradiance is used in the system, lower temperature and salinity are required to achieve efficient energy production. the salinity requirements in the orc also increase with an increase in the salinity of the system. however, the salinity requirement in the solar pond increases as well as decreases with an increase and decrease in solar irradiance. this study also highlights the fact that the turbine has a more significant effect than the other parts of the system on the overall efficiency of the system.solar-pond assisted reverse osmosis-electrodialysis system for seawater desalination and hydroponic fertilizer solution productionall authors namra mir & yusuf bicer published online:15 december 2021table 3. energy and exergy efficiency of the systems
