A special spray gel formulation of Ecosorb® odor eliminator topically encapsulates material, blocking odors from escaping into the atmosphere. Ecosorb® Spray Gel® is an ideal solution for sludge handling and transportation, open-bed waste trucks, working faces of landfills, soil remediation projects, and other solid/semi-solid odorous materials that continuously emit odors.
Veolia’s patent-pending CoStrip degases raw water by introducing microbubbles of a stripping gas (air, nitrogen or fuel gas) counter-current to the liquid stream. First, the microbubbles are introduced into a series of chambers utilizing eductors. Next, they rise and capture dissolved gases due to the disequilibrium between the microbubble gases and the dissolved gases in the water.
Water from cooling towers attracts and absorbs airborne contaminants on a continuous basis. Typically, 85% of suspended solids in cooling water and hot water loops are smaller than 5 microns. Scientific studies have shown that these small particles (5 microns and less) are the adherent contaminants fouling the water loop and process cooling system.
Founded in 2017, under the consolidation of global water industry leaders Emefcy and RWL Water, Fluence was established with a vision to become the key global provider in decentralized water and wastewater solutions.
O’Brien, Texas is just one of thousands of small communities in the United States that struggle to find the resources to ensure that the water coming out of the tap is safe to drink. The recent budget proposal by the Trump administration will only make matters worse. Watch this documentary short produced by Tom Rosenberg and Earth Institute fellow Madison Condon details one shrinking town’s drinking water crisis.
How researchers at UC Merced are developing a better understanding of the three sources of water upon which California depends in order to adapt to the effects of environmental changes and make better use of this most precious of our natural resources.
Utilities are faced with myriad threats looming in the future, but chief among them is increased stress from population growth. In Denver, comprehensive planning for that future is underway.
Amid growing concerns around algal bloom, industrial operations are under pressure to stop using phosphorus-based water treatment technology. But transition to an alternative can be daunting.
India is making great strides to aggressively expand its renewable energy capacity. But the country's power sector remains highly reliant on thermoelectric plants, with high demand for water for cooling. That means that droughts, like the one caused last year by weak monsoons, can shut off the power, hampering the economy and potentially endangering lives.
Resiliency is a hot button word right now. Ten years ago, advocates focused on “adaptation,” or the idea of adapting to the coming effects of climate change. Now the focus is on “resiliency,” the ability to bounce forward — not backward — when something disastrous happens.
We’re entering the home stretch of the 85th Session of the Texas Legislature.
It may sound intimidating, but water that has been treated to “ultrapure” condition is more than necessary in many applications. This highly-cleansed product is a fundamental part of many industrial operations, from the medicine we need to get well to the power we rely on in our daily lives. But, as the name implies, it’s no small task to get average influent to the ultrapure level.
By harvesting heating, ventilation, and air conditioning (HVAC) condensate, industrial operations can take advantage of a cool, convenient source of clean water.
By making strategic choices to maximize energy-water efficiencies, we can help protect our supplies in advance of our next drought. Here are three ways that work.
What would happen if there was an emergency in the U.S. that caused radioactive material to contaminate drinking water supplies? What steps could your utilities and government take?
Deep in the Israeli desert is an academic institute that is building peace in the region by putting nature at its center. The Arava Institute, in partnership with Ben Gurion University, brings students from Israel, Palestine, Jordan, and around the world to find common ground around environmental problems and build trust — and peace — from there.
At my household, a new year means a new energy and water-use baseline. By that I mean, every month, I look at how much electricity and water I used in comparison to the same month the previous year — so I can try to be as efficient as possible. But I work in the energy field, and I know that’s not a typical New Year’s tradition. Most people don’t examine the trends of their energy-use or spend much time thinking about how to reduce it.
