“…This was about ten times greater than the basin and reflector systems. In their recommendations, Lim et al, [21] noted that there is need for optimization studies, including economic feasibility. The total real cost of a process, for example, consists of the amortization rate (i.e., price of borrowing money to build a desalination system), the maintenance and operating costs, and the price of energy.…”

“…With population growth, and increasing domestic wastewater, industrial pollution, and water wastage, the problem of freshwater resource shortage will be further aggravated; therefore, the desalination of seawater and the purification of wastewater technologies are of strategic importance in terms of solving the global scarcity of freshwater resources and achieving sustainable development. At present, multistage flash distillation [ 3 , 4 ], multieffect distillation [ 5 , 6 ], and reverse osmosis [ 7 , 8 ] technologies are widely used in the field of seawater desalination and wastewater purification and have achieved good results. However, there are also disadvantages, such as the ease of scaling, the high energy consumption, and the stability of filter membranes.…”

Solar-driven interface water evaporation is an energy-saving, environmentally friendly, and efficient seawater desalination and wastewater treatment technology. However, some challenges still restrict its further industrial development, such as its complex preparation, heavy metal pollution, and insufficient energy utilization. In this study, a photothermal layer based on flower-shaped carbon nanoparticles is presented for highly efficient solar-driven interface evaporation for water treatment applications. The results show that the surface of the prepared carbon nanomaterials presents a flower-shaped structure with an excellent light absorption capacity and a large specific surface area. Moreover, the C-5.4 (Carbon-5.4) sample has an evaporation rate of 1.87 kg/m2/h and an evaporation efficiency of 87%—far higher than most photothermal materials. In addition, carbon nanomaterials have an excellent ion scavenging capacity, dye purification capacity, and outdoor practical performance. This study provides a new solution for the application of carbon nanomaterials in the field of water purification.

“…The process of converting seawater to drinking water using thermal or pressure-driven processes is extremely intensive in terms of energy consumption, engineering design, operation, and maintenance. The current solutions utilized for producing drinking water from seawater largely rely on thermal methods, such as multi-stage flash and multi-effect distillation (MSF and MED, respectively) [4][5][6][7], as well as pressure-driven seawater reverse osmosis (SWRO) [7,8], which comprises about 70% of desalination processes worldwide. SWRO has emerged as the most mature and widely accepted technology, with thousands of installations worldwide with a combined capacity of more than 200 million gallons per day, which includes brackish water and seawater systems [9].…”

Novel tri-bore polyvinylidene difluoride (PVDF) hollow fiber membranes (TBHF) were scaled-up for fabrication on industrial-scale hollow fiber spinning equipment, with the objective of validating the membrane technology for membrane distillation (MD) applications in areas such as desalination, resource recovery, and zero liquid discharge. The membrane chemistry and spinning processes were adapted from a previously reported method and optimized to suit large-scale production processes with the objective of translating the technology from lab scale to pilot scale and eventual commercialization. The membrane process was successfully optimized in small 1.5 kg batches and scaled-up to 20 kg and 50 kg batch sizes with good reproducibility of membrane properties. The membranes were then assembled into 0.5-inch and 2-inch modules of different lengths and evaluated in direct contact membrane distillation (DCMD) mode, as well as vacuum membrane distillation (VMD) mode. The 0.5-inch modules had a permeate flux >10 L m−2 h−1, whereas the 2-inch module flux dropped significantly to <2 L m−2 h−1 according to testing with 3.5 wt.% NaCl feed. Several optimization trials were carried out to improve the DCMD and VMD flux to >5 L m−2 h−1, whereas the salt rejection consistently remained ≥99.9%.
