and looks like a chemistry experiment with two electrodes one positive the other negative plunged into a bottle of wastewater.
Engineers estimate that the microbial battery can extract about 30 percent of the potential energy locked up in wastewater.
Of course there is far less energy potential in wastewater. Even so the microbial battery is worth pursuing because it could offset some of the electricity now used to treat wastewater.
That use currently accounts for about 3 percent of the total electrical load in developed nations.
Most of this electricity goes toward pumping air into wastewater at conventional treatment plants where ordinary bacteria use oxygen in the course of digestion just like humans and other animals.
or by swilling the coals in any remaining cooking water and pouring into a small hole nearby.

#Virtual Curtain technology treats mining wastewater A new cost-effective technology to treat mining wastewater and reduce sludge by up to 90 per cent has been used for the first time at a commercial mine.
The technology, called Virtual Curtain, was used to remove metal contaminants from wastewater at a Queensland mine
Given the Australian mining industry is estimated to generate hundreds of millions of tonnes of wastewater each year,
Dr Douglas and his team developed the technology after discovering that hydrotalcites could be formed by adjusting the concentrations of common wastewater contaminants, aluminium and magnesium,
to an ideal ratio and then by increasing the ph. y using contaminants already present in the wastewater we have avoided the need for expensive infrastructure
and Chile. t is a more efficient and economic way to treat wastewater and is enabling the global mining industry to reduce its environmental footprint and extract wealth from waste.
That is the conversion of waste n this case both locally sourced food waste and human sewage nto a methane-rich biogas.

Gates envisions that each Omniprocessor will be built and operated using a micro-entrepreneurial model where local residents would benefit economically from the facilities. he processor wouldn just keep human waste out of the drinking water;
it would turn waste into a commodity with real value in the marketplace. It the ultimate example of that old expression:

This process enhances naturally occurring anaerobic digestion in wastewater Silver says, as it stabilizes treatment, improves biogas quality,
Treated wastewater exits the reactor with 80 to 90 percent of pollutants removed, so it can be used for irrigation, equipment washing,
The system can treat 10,000 to 1 million gallons of wastewater daily. At that rate, a winery would shave about 2 pounds of CO2 per case off of its carbon footprint
through carbon-free energy generation and avoiding municipal wastewater treatment ffectively planting over 4, 400 acres of trees in a year,
It could also eliminate 10 trucks of wastewater shipping per day for Lagunitas. All in the design Increasingly, the beverage industry has employed anaerobic and aerobic wastewater treatment processes
Aerobic processes dissolving air into wastewater, where aerobic microorganisms degrade pollutants consume a lot of energy and generate biosolids (organic materials) that are managed at cost.
and wastewater pollution is rising, causing many companies to consider water risk in their overall strategy.
To that end, Cambrian is working on other projects that leverage exoelectrogenic microbes to treat wastewater. One project, called Biovolt, is powered a self water treatment system for U s army forward operating bases that treats wastewater

An executive from a water company even wrote an open letter to Jay z, reminding him that it costs money.
The treatment method, known as microbial electrolytic carbon capture (MECC), purifies wastewater by using an electrochemical reaction that absorbs more CO2 than it releases
and the decomposition of organic material within the wastewater itself. Plus, existing wastewater treatment technologies consume high amounts of energy.
Public utilities in the US treat an estimated 12 trillion gallons of municipal wastewater each year and consume about 3 percent of the nation grid energy.
MECC uses the natural conductivity of saline wastewater to facilitate an electrochemical reaction that is designed to absorb CO2 from both the water and the air.
The findings offer the possibility that wastewater could be treated effectively on-site without the risks or costs typically associated with disposal.

#Nose-Like Biosensor Sniffs Out Stinky Drinking water Electronic noses can detect bugs, disease or even explosives.
Now scientists have applied similar technology to detecting contaminated drinking water, according to a study published recently in the journal Biosensors and Bioelectronics.
But the resulting drinking water is almost never pure H2o; even the most potable water contains a cocktail of dissolved chemicals that give it a unique flavor
or cause slight variations in its ph. Researchers have found that the human nose is very sensitive to two molecules that often slip through the treatment process:
whether these molecules are in drinking water, a process that is expensive and time-consuming. A team of South korean researchers has developed a simple sensor based on the human nose to sniff out the smelly molecules.
