“…The solution-diffusion model was primarily used for the description of the water purification [30,33,36,38,47,50,64,65], including sea water [25,40,41,43,49,52,55,57,61,66] and brackish water [20,31,42,45,58,59,60,65] desalination, and also the wastewater treatment [30, 48, 51, 53-54, 56, 67]. Also, with using of this model it was described the processes of the removal of zinc [32], boron [28,52], chlorophenol [36,38], N-nitrosodimethylamine [38,63], weak acids [25], and ammonia compounds [51,54], apple juice concentration [35,37], and also for the membrane characterization [46].…”

“…The important factor of the successive optimization procedure includes the choice of the target function and the optimization criterion. As in 20200-2010, in the considered period in most works authors used the economical optimization criteria, primarily the minimization of costs [49,61,[74][75][202][203][204][205][206][207][208][209][210][211][212][213][214][215][216][217], and also the minimization of the energy consumption, which is the significant part of the operational cost [27,38,49,66,73,[204][205][219][220][221][222][223][224][225][226][227][228]. Also, the economic criteria included the profit maximization [229][230], and the minimization of the cost factor, which in work [231] was determined as the ratio of the water price and energy price in a hybrid system with reverse osmosis and pressure retarded osmosis.…”

“…For the optimization problem solution, a large number of methods and algorithms can be used. In the considered researches the most widely used methods included the nonlinear programming [35, 49, 61, 74-75, 204-211, 218, 222, 229-230], the generic algorithm [28,38,237,[241][242], the particle swarm method [202,247,250], the sequential quadratic programming [219,233], the surface response methodology [232], the pattern search algorithm [251], the harmony search algorithm [66], and the bees algorithm [213]. The work [216] should be pointed out, since in it the nineteen optimization algorithms were considered and compared.…”

Reverse osmosis is an essential technological separation process that has a large number of practical applications. The mathematical simulation is significant for designing and determining the most effective modes of membrane equipment operation and for a deep understanding of the processes in membrane units. This paper is an attempt at systematization and generalizing the results of the investigations dedicated to reverse osmosis simulation, which was published from 2011 to 2020. The main approaches to simulation were analyzed, and the scope of use of each of them was delineated. It was defined that computational fluid dynamics was the most used technique for reverse osmosis simulation; the intensive increase in using of molecular dynamics methods was pointed out. Since these two approaches provide the deepest insight into processes, it is likely that they will further be widely used for reverse osmosis simulations. At the same time, for the simulation of the membrane plant, it is reasonable to use the models that required the simplest solutions methods. The solution-diffusion model appears to be the most effective and flexible for these purposes. Therefore, this model was widely used in considering the period. The practical problems solved using each of the considered approaches were reviewed. Moreover, the software used for the solution of the mathematical models was regarded.

“…Kim et al modeled the practical design of a 100 000 m 3 day −1 two‐stage SWRO to improve the energy efficiency under various operating conditions. [ 137 ] With the same number of membrane modules, both single‐ and two‐stage SWRO offered similar permeate quality but the latter always exhibited greater energy consumption for a given recovery rate. The optimal ratio of the number of pressure vessels for the first stage to the second was determined as the function of ERD type.…”

Energy Efficient Seawater Desalination: Strategies and Opportunities

2021

With the change in climate patterns, rapid industrialization, and population growth, the increasing water and energy demand became a major concern in the past decades. Desalination has been touted as the answer to the global water crisis, due to its capability in producing high‐quality fresh water from saline water. The continual research and innovations in the desalination field have resulted in the commercialization of large‐scale desalination in many water scarce regions. In the energetic context, all desalination processes are energy intensive. With the necessity to make desalination a more affordable and sustainable process, the energy efficiency of desalination is becoming an important topic. Herein, it is aimed to provide insights into the recent efforts and strategies established to tackle the energy‐related issues of both, thermal‐based and membrane‐based desalination processes. Depending on the principle of various commercial and emerging desalination processes, the directions of energy efficiency improvements, which include operating condition optimization, high‐performance material development, and renewable energy exploitation are discussed. The ideas and strategies reviewed herein, whether in their implementation or theoretical stage, are expected to provide insights into the possible improvement for application in commercial desalination plants.

“…Numerous publications have researched the optimisation of brackish water reverse osmosis (BWRO) (5000–15,000 mg/L TDS) [ 4 , 5 , 6 , 7 , 8 ] and salt water reverse osmosis (SWRO) (15,000 mg/L–35,000 mg/L) [ 4 , 5 , 9 , 10 , 11 ]. However, it is much less energy-intensive to perform reverse osmosis on low salinity water between 500 and 5000 mg/L as there is less osmotic pressure to overcome.…”
