A nature-inspired hydrogen-bonded supramolecular complex for selective copper ion removal from water

August 7, 2020

Herein, we present a scalable approach for the synthesis of a hydrogen-bonded organic–inorganic framework via coordination-driven supramolecular chemistry, for efficient remediation of trace heavy metal ions from water. <read more>

Polluted Wastewater in the Forecast? Try A Solar Umbrella

Scientists use a powerful microbial detection device to show that suggestions of sewage in Kauai’s watershed were mostly false positives. <read more>

New Recipes for Taking Salt Out of Seawater

August 26, 2019

As populations boom and chronic droughts persist, coastal cities like Carlsbad in Southern California have increasingly turned to ocean desalination to supplement a dwindling fresh water supply.

Now scientists at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) investigating how to make desalination less expensive have hit on promising design rules for making so-called “thermally responsive” ionic liquids to separate water from salt. <read more>

Moving Forward on Desalination

August 26, 2019

Scientists at Berkeley Lab have been exploring different approaches for efficiently separating out salt and other contaminants to generate water that’s fit for drinking or other uses, such as agricultural irrigation. For example, they’re looking at charge-based brackish water desalination, nanoconfinement of water, better membranes, and other advanced water treatment techniques. <read more>

Can We Reuse Polluted Water? Yes, Add Bacteria

August 26, 2019

Drilling a single oil or natural gas well with hydraulic fracturing requires between 1.5 to 16 million gallons of water. When the well starts flowing, the fluid that is brought back to the surface alongside the oil and gas is a combination of the injection fluid and brine from aquifers – a difficult-to-treat mixture known as produced water. Brimming with hydrocarbons, harsh salts, and industrial chemicals, the vast majority of produced water is injected into disposal wells after it is collected. Currently, less than 1% of the billions of gallons generated each year is reused.

How can this “wastewater” be turned into usable water? One answer: Let microbes do the work. <read more>

To Pump or Not to Pump: New Tool Will Help Water Managers Make Smarter Decisions

August 26, 2019

The overpumping of groundwater in California has led to near environmental catastrophe in some areas – land is sinking, seawater is intruding, and groundwater storage capacity has shrunk. But researchers at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) believe machine learning could be part of the solution to restoring groundwater to sustainable levels and quality. <Read more>

Lab Water Technology Among Best in the World

April 22, 2019

Water-purifying technology developed at Lawrence Berkeley National Lab (Berkeley Lab) was named among only five in the world that meet current international standards in a recent study from United Nations University examining systems for small communities.
