The quest for clean water is a universal one, and as populations grow and climates change, this challenge becomes more urgent. Novel seawater purification techniques research offers hope, promising new and innovative methods to access this vital resource. Traditionally, we’ve relied on methods like reverse osmosis and multi-stage flash distillation. However, these methods can be expensive ...
In a world grappling with an ever-growing demand for freshwater, the significance of key factors impacting desalinated water quality has never been more pronounced. As our global population swells, urbanization accelerates, and the climate undergoes transformation, the need for access to freshwater has reached critical levels. By 2025, it is projected that nearly two-thirds of the world’s ...
Titanium carburizing electrodes were used as the electrodes in a capacitive deionization (CDI) process for desalination in this study. Two methods of high vacuum magnetron sputtering and chemical deposition were used for the preparation of nano-titanium carburizing electrodes (named Ti-C* and Ti-C**). ...
In recent years, capacitive deionization (CDI) has been reported as one of the emerging technologies developed with the purpose of water desalination. ...
Affordable carbon composite electrodes were developed to treat low-concentrated groundwater using capacitive deionization (CDI). A carbon slurry prepared using activated carbon powder (ACP), poly(vinylidene fluoride), and N-methyl-2-pyrrolidone was employed as a casting solution to soak in a low-cost porous substrate. The surface morphology of the carbon ...
In this work, the capacitive deionization (CDI) performance of a single-walled carbon nanotube (CNT) electrode has been studied from the point view of charge efficiency theory. ...
The study aimed at further developing an integrated capacitive deionisation (CDI)-based process to treat reverse osmosis (RO) brine from a water reclamation facility to increase the overall water recovery to more than 90% and to achieve a sustainable operation of the process with optimised conditions. The normalised treatment capacity of CDI membranes and voltage was optimised at 24.8 ...
For sustainable operation of CDI organic fouling control and effective organic fouling cleaning should be further studied.Keywords: biological activated carbon, capacitive deionization, RO brine, RO ...
In this paper, three types of ordered mesoporous carbons (OMCs) were synthesised by an original template method and a modified sol-gel process involving nickel salts. The effects of pore arrangement pattern (ordered and random), and pore size distribution (mesoporous and microporous) on the desalination performance were investigated by comparing mesoporous carbons with activated carbons (ACs). It ...
