#Colonies of wired microbes turn sewage into electricity Stanford university rightoriginal Studyposted by Tom Abate-Stanford on September 19 2013a new way to generate electricity from sewage uses naturally occurring ired microbesas mini power plants
Scientists hope the icrobial batterycan be used in places such as sewage treatment plants or to break down organic pollutants in the ead zonesof lakes
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.

#Brewing up sustainability Each day, breweries and wineries produce thousands of gallons of wastewater, which is poured either down the drain

In these units, microbes called xoelectrogensexecute a unique process, electromethanogenesis which is being used for the first time ever in treating wastewater.
consume the wastewater remaining organic pollutants and, in the process, generate electricity. This electricity travels through a circuit and onto cathodes coated with separate microbes that consume that electricity
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

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
but these are expensive and difficult to adopt, Silver says. 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
and generates electricity to power itself. Another project, funded by the National Science Foundation, uses exoelectrogens to sense nitrate in wastewater, cheaply and with very high specificity,
for the agricultural industry. arth as a spaceshipecovolt is valuable today as a solution to Earth water issues.
This made exoelectrogens a third and largely better candidate for wastewater treatment, over aerobic or anaerobic methods.
Launching Cambrian with a Department of agriculture grant to focus on agricultural wastewater, the team soon moved to its current Boston headquarters.

#Wastewater treatment Captures Carbon emissions, Produces Energy A wastewater treatment process developed by engineers at the University of Colorado Boulder mitigates carbon dioxide emissions and actively captures greenhouse gases.
The treatment method, known as microbial electrolytic carbon capture (MECC), purifies wastewater by using an electrochemical reaction that absorbs more CO2 than it releases
Wastewater treatment typically produces CO2 EMISSIONS in two ways: the fossil fuels burned to power the machinery, 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. Existing carbon capture technologies are energy-intensive and often entail costly transportation and storage procedures.
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 process transforms CO2 into stable mineral carbonates and bicarbonates that can be used as raw materials by the construction industry,
used as a chemical buffer in the wastewater treatment cycle itself or used to counter acidity downstream from the process such as in the ocean.
The findings offer the possibility that wastewater could be treated effectively on-site without the risks or costs typically associated with disposal.
A carbon-negative wastewater treatment system could benefit power companies, the authors say, as the EPA Clean Power Plan requires power plants to comply with reduced CO2 EMISSION levels. e

#Water purification: Running fuel cells on bacteria Researchers in Norway have succeeded in getting bacteria to power a fuel cell.
The"fuel"used is wastewater, and the products of the process are purified water droplets and electricity.
This is an environmentally-friendly process for the purification of water derived from industrial processes and suchlike. It also generates small amounts of electricity--in practice enough to drive a small fan, a sensor or a light-emitting diode.
In the future, the researchers hope to scale up this energy generation to enable the same energy to be used to power the water purification process
Since the waste in the wastewater (organic material) is consumed and thus removed, the water itself becomes purified,
and bacteria that are suited best for use in this water purification method, "says Netzer.""To start with, we had to find a bacterium which was not only able to consume the waste products in the water,
