The world is facing a water crisis. With increasing populations, industrialization, and climate change, fresh water sources are becoming scarce. Desalination – the process of removing salt and impurities from seawater – has become an attractive solution to this crisis. However, traditional desalination methods are energy-intensive, expensive, and not environmentally friendly. Enter jellyfish-inspired desalination. Scientists […]
Graphene oxide membranes have garnered significant attention in recent years due to their unique properties and potential applications in various fields including water filtration, gas separation, and energy storage. Graphene oxide, a derivative of graphene, is a two-dimensional material composed of carbon, oxygen, and hydrogen atoms. Its structure consists of a single layer of carbon […]
Electrodialysis reversal (EDR) is a membrane-based separation process that utilizes an electric field to transport ions across selective ion exchange membranes. This technology has gained significant attention in recent years due to its ability to remove various ions, including salts, from water streams in a highly efficient manner. In this article, we will delve into […]
Capacitive deionization (CDI) is a promising technology that has emerged in recent years as an efficient and cost-effective method for removing ions from water. This innovative technique has shown great potential in various applications, including desalination, water purification, and wastewater treatment. CDI works by using two porous electrodes, typically made of activated carbon, that are […]
Desalination, or desalting, refers to processes that remove salts and minerals from saline water to produce fresh water suitable for human consumption or irrigation. As supplies of fresh water across the globe grow scarce while demand continues rising, desalination technologies have become increasingly critical for providing populations with adequate water. Desalting technologies can be separated […]
From the gas pump to the synthetic fertilizers that help feed the world, petroleum products facilitate almost every aspect of modern life. But this ubiquitous fossil fuel comes with an overlooked and mounting environmental toll – for every barrel of crude oil extracted, an astounding 10 barrels of salty, contaminated wastewater called “produced water” surfaces […]
As water scarcity intensifies globally, innovative technologies are needed to ensure adequate supply and optimize treatment. Water processes based on osmosis, the natural diffusion of water across a semi-permeable membrane, have generated growing interest for their efficiency, reliability, and environmental sustainability. Engineered osmosis methods like forward osmosis (FO) and pressure-retarded osmosis (PRO) utilize optimized membranes […]
