“…The ED technology adapts to power fluctuations better than RO; thus, the integration of ED with RE has shown a better performance [15,22], being a promising alternative if it is integrated with solar PV energy (ED-PV) [13]. Several ED-PV pilot-scale plants have been built [23]. The main current drawbacks and challenges for ED development are related to the intensive use of energy required, the development of antifouling and anti-scaling strategies, and the high costs of IEM [13,23,24].…”

Electro-membrane technologies are versatile processes that could contribute towards more sustainable seawater reverse osmosis (SWRO) desalination in both freshwater production and brine management, facilitating the recovery of materials and energy and driving the introduction of the circular economy paradigm in the desalination industry. Besides the potential possibilities, the implementation of electro-membrane technologies remains a challenge. The aim of this work is to present and evaluate different alternatives for harvesting renewable energy and the recovery of chemicals on an SWRO facility by means of electro-membrane technology. Acid and base self-supply by means of electrodialysis with bipolar membranes is considered, together with salinity gradient energy harvesting by means of reverse electrodialysis and pH gradient energy by means of reverse electrodialysis with bipolar membranes. The potential benefits of the proposed alternatives rely on environmental impact reduction is three-fold: (a) water bodies protection, as direct brine discharge is avoided, (b) improvements in the climate change indicator, as the recovery of renewable energy reduces the indirect emissions related to energy production, and (c) reduction of raw material consumption, as the main chemicals used in the facility are produced in-situ. Moreover, further development towards an increase in their technology readiness level (TRL) and cost reduction are the main challenges to face.

“…The freshwater shortage, energy crisis, environmental pollution are the three main challenges facing human beings in modern society (Delgado et al 2020;Lewis 2007;Mir and Bicer 2021). In spite of the fact, nearly three-quarters of the world is covered by water, the vast majority of the Earth's water is mostly in the oceans and is saline, resulting in less than 1% of water can be directly available by residents, and more than one-third of the world's population is affected by freshwater scarcity (Liu et al 2018; Ma et al 2020; Ridoutt and P ster 2010).…”

Nowadays, freshwater shortage, energy crisis and environmental pollution are the three major threats to human beings. Herein, we develop a photothermal material based on bagasse for solar steam generation to relieve freshwater crisis and mitigate environmental pollution caused by bio-waste. The mainly functional part of the solar driven steam generator in this paper is bagasse-based photothermal aerogel (B-PTA), which composes of carbonized bagasse (CB) and bagasse-derived cellulose ber (BDCF). The B-PTA with CB can effectively absorb solar (~95%) and has an excellent light-to-heat ability. The B-PTA with DBCF has super-hydrophilicity, water transport and retention ability. Depending on the excellent light absorption and 3D water passageway, the B-PTA gives a water evaporation rate of 1.36 kg m -2 h -1 , and can achieve a photothermal conversion e ciency of 77.34% under 1-sun illumination (1 kW m -2 ). The B-PTA has excellent stability that the e ciency without signi cant decrease after 20 cycles. In addition, the B-PTA can effectively desalt seawater and purify dye wastewater with natural sunlight. Therefore, turning bio-waste into valuable photothermal material for solar steam generation is possible. Due to the merits of low cost, scalability, environmental friendliness, B-PTA has the potential for real-world water puri cation.
