“…There is little research on the development of ERD devices for small-scale plants (production less than 50 m 3 /day). A study carried out with a new HPP-ERD device showed that with an additional investment of 6.3% in this type of device, it is possible to reduce the fresh water cost produced between 17.8 and 21.9%, as well as reduce the capital recovery period by 12.3%, using ERD devices designed for these low fresh water productions [85].…”

Reverse osmosis is the leading technology for desalination of brackish water and seawater, important for solving the growing problems of fresh water supply. Thermal technologies such as multi-effect distillation and multi-stage flash distillation still comprise an important portion of the world’s desalination capacity. They consume substantial amounts of energy, generally obtained from fossil fuels, due to their low efficiency. Hybridization is a strategy that seeks to reduce the weaknesses and enhance the advantages of each element that makes it up. This paper introduces a review of the most recent publications on hybridizations between reverse osmosis and thermal desalination technologies, as well as their integration with renewable energies as a requirement to decarbonize desalination processes. Different configurations provide improvements in key elements of the system to reduce energy consumption, brine production, and contamination, while improving product quality and production rate. A combination of renewable sources and use of energy and water storage systems allow for improving the reliability of hybrid systems.

“…20 In addition, some researchers have carried out extensive research on seawater energy recovery. As less research has been reported on small-scale ERDS in SWRO desalination, a new piston-type HPP-ERD that simultaneously pressurizes raw seawater and recovers water energy from concentrated brine was invented by Daiwang et al 11 and tested on a simulated laboratory platform. The test results show that the HPP-ERD is not a single high-pressure pump and also significantly reduces the payback period and desalination costs of the proposed project.…”

“…After several experimental tests, the results showed that the commercial utilization of the device was very high due to reduced volume mixing and improved volume utilization 10 . As less research has been reported on small‐scale ERDS in reduced seawater reverse osmosis (SWRO) desalination, a new piston type high‐pressure pump‐energy recovery device (HPP‐ERD), which simultaneously pressurizes raw seawater and recovers water energy from concentrated brine, was invented by Song et al 11 and tested on a simulated laboratory platform. The test results show that the HPP‐ERD is not a single high‐pressure pump and also significantly reduces the payback period and desalination costs of the proposed project.…”

Due to the rapid development of today's industry, it not only greatly accelerates the consumption of energy, but also causes serious pollution to the environment. Therefore, reducing energy waste and recovering energy has become an important research direction today. This paper introduces the future development trend of renewable energy, discusses the progress of recovery of nonpolluting energy such as marine, bioenergy and thermal energy, and analyzes the efficiency and social benefits of various types of energy recovery. Energy recovery methods for natural gas pipelines are briefly analyzed, and current research advances in energy pressure recovery devices are provided, leading to a summary of methods to improve the efficiency of fluid energy recovery. Finally, it is concluded that although the current energy sources are diversified, the most valued energy sources at present and in the future should be solar energy and ocean, which are infinitely recyclable. This paper will benefit researchers to further understand and study the various aspects of energy recovery.

“…The use of NF as a pretreatment before RO can reduce water hardness [ 53 ]. Indeed, NF membranes are negatively charged and reject divalent ions, which can induce scaling [ 54 ]. In addition, NF can also reduce total dissolved salts (TDS) and remove microorganisms, turbidity and organic matter.…”

“…Much research is still ongoing to develop new energy recovery systems. For example, Song et al [ 54 ] introduced a new piston-type integrated high pressure pump-energy recovery device that synchronously pressurizes the feed seawater and recovers the hydraulic energy from the concentrated brine. The utilization of this new device, instead of a single high-pressure pump, was shown to decrease both the payback period and the desalinated water cost.…”

Water supply and water treatment are of major concern all around the world. In this respect, membrane processes are increasingly used and reported for a large range of applications. Desalination processes by membranes are well-established technologies with many desalination plants implemented in coastal areas. Natural water treatment is also well implemented to provide purified water for growing population. This review covers various aspects of desalination: membranes and modules, plants, fouling (scaling, biofouling, algal blooms), cleaning, pretreatment (conventional and membrane treatments), energy and environmental issues, renewable energies, boron removal and brine disposal. Treatment of natural water focuses on removal of natural organic matter, arsenic, iron, nitrate, fluoride, pesticides and herbicides, pharmaceutical and personal care products. This review underlines that desalination and natural water treatment require identical knowledge of membrane fouling, construction of large plants, cleaning procedures, energy and environmental issues, and that these two different fields can learn from each other.
