Membrane Technology

It pays to be positive(ly charged)!

A new nanofiltration process developed at MIT can curb the hazardous waste generated from aluminum production.

The average liter of bottled water has nearly a quarter million invisible pieces of ever so tiny nanoplastics, detected and categorized for the first time by a microscope using dual lasers.

Many futuristic novels and films have explored what the world might look like without water. But water scarcity isn't a problem for the far-off future: it's already here.

LifeStraw not only creates useful water filters for use at home and in the backcountry, but with every purchase the company provides clean water to a child in need around the globe. We talked to LifeStraw's CEO to learn about all things LifeStraw from its filters to its humanitarian efforts.

Industrial processes often generate a large amount of alkaline waste solutions. The existing alkali treatment processes require high investment, and are complicated and have a low rate of efficiency. Membrane technology has the advantages of high efficiency and energy savings. However, current polymeric membrane materials are not strong enough in harsh alkaline environments. To solve this problem, Prof. Li Pei from…

Researchers have developed a new membrane technology that allows for more efficient removal of carbon dioxide (CO2) from mixed gases, such as emissions from power plants.

One person's wastewater is another person's treasure. A new Stanford University study paves the way to mining sewage for valuable materials used in fertilizers and batteries that could someday power smartphones and airplanes. The analysis, published recently in ACS ES&T Engineering, reveals how to optimize electrical processes for transforming sulfur pollution, and could help lead to affordable, renewable…

Promising technologies for converting wastewater into drinkable water produce a chemical compound that can be toxic, corrosive and malodorous. An analysis of one possible solution reveals ways to optimize it for maximum energy efficiency, pollutant removal and resource recovery.

Morphogenesis is nature's way of building diverse structures and functions out of a fixed set of components. While nature is rich with examples of morphogenesis—cell differentiation, embryonic development and cytoskeleton formation, for example—research into the phenomenon in synthetic materials is scant. University of Illinois Urbana-Champaign researchers are taking a step forward using electron tomography, fluid…

Carry clean water with you by using the only the best filtered water bottles -- vetted and tested by us.

Every year, beer breweries generate and discard thousands of tons of surplus yeast. Researchers from MIT and Georgia Tech have now come up with a way to repurpose that yeast to absorb lead from contaminated water.

A filtered water bottle allows you to have great tasting water that's also better for your health in the long run. We tried options from brands like LifeStraw, Grayl, and Brita.

New research shows that the average liter of bottled water has nearly a quarter million invisible pieces of ever so tiny nanoplastics.

In Japan, Toray Industries, Inc., has invested a further $8 million in Cellulosic Biomass Technology Co., Ltd., to lift its stake in that subsidiary from 67%, to 84.4%. Toray established that entity in Bangkok with Mitsui DM Sugar Co., Ltd., in January 2017 to demonstrate membrane-based saccharification process technologies. Toray looks to employ the additional […]

The water coming out of your faucet is safe to drink, but that doesn't mean it's completely clean. Chlorine has long been the standard for water treatment, but it often contains trace levels of disinfection byproducts and unknown contaminants. Georgia Institute of Technology researchers developed the minus approach to handle these harmful byproducts.

Multi-omics on a long-term, continuous bioreactor experiment identifies microbes able to respire nitric oxide, a toxic, ozone-depleting, greenhouse gas precursor.

San Francisco is at the forefront of a movement to recycle wastewater from buildings, homes, and neighborhoods and use it for toilets and landscaping.

San Francisco is at the forefront of a movement to recycle wastewater from commercial buildings, homes, and neighborhoods and use it for toilets and landscaping. This decentralized approach, proponents say, will drive down demand in an era of increasing water scarcity.

Oil spills and industrial pollution pose a huge threat to the ecological environment. Concerns over safety have seen an increased focus on improving the filtration of oily wastewater; for example, during the treatment of sewage. Membrane separation technology offers a promising and efficient option for treating that wastewater, particularly with its low energy consumption. However, it remains a challenge to find…
