#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
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.
and photocatalysts Drinking clean water is something that many people in the world can't take for granted as they rely on polluted sources
In response to that problem Panasonic is developing a new technology that looks to the sun to clean water extracted from the ground.

000 people and, from that, produce 86,000 liters of clean water on a daily basis while also generating a net 250 kilowatts of electricity.
the Gates Foundation will promote the building of self-powered Omniprocessor facilities in other parts of the world (Gates specifically mentions India) where clean drinking water
usually via drinking water supplies that have been contaminated by human waste. 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:
and water companies the system can also detect leaks in water pipes, or in petroleum pipelines about setting up field tests under real-world conditions.

#Brewing up sustainability Each day, breweries and wineries produce thousands of gallons of wastewater, which is poured either down the drain
and create power from wastewater. The company which aims to leverage biotechnology as a way to solve environmental issues is also modifying their system to generate value from wastewater in agricultural and military fields,
and to convert carbon dioxide to fuels for applications On earth and in space. Today industrial infrastructure manages basic resources linearly
now the company chief technology officer. he treatment of wastewater, for example, consumes over 3 percent of the electricity in the United states,
yet organics in the wastewater have energy that can be extracted and used locally, Silver says. nd that the case for a lot of waste products in general.
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
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
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.
Launching Cambrian with a Department of agriculture grant to focus on agricultural wastewater, the team soon moved to its current Boston headquarters.

and extensive burst release. arnessing nanoparticles in Africatheresa Dankovich uses nanotechnology to purify drinking water in Africa.
One page can filter 26 gallons of drinking water; one book can filter a person water needs for four years.
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.

Better water supply in karst areas Drinking water is scarce in the Indonesian region of Gunung Kidul.
In the next step bacteria in the tap water are reduced. For this purpose the KIT scientists established a pilot plant at the hospital of Wonosari There bacteria in the water are reduced among others by UV radiation
The inhabitants collect tap water and rainwater in a local open pool. There animals and plants can pollute the water.
Within the framework of another partial project a team of KIT scientists headed by Stephan Fuchs expert for aquatic environmental engineering worked in the area of sewage and waste treatment.
Fecal matter is collected first in septic tanks--large concrete basins. -In cooperation with the industry partner the scientists built a second pilot plant at Wonosari hospital.
In the villages there frequently are no septic tanks. Toilets are located above a pit and are moved if necessary.
In the region of Pucanganom we installed a system that processes toilet sewage of 15 families and the dung of their animals in three biogas facilities.
"Human activities such as agriculture, fossil fuel combustion, wastewater management and industrial processes are increasing the amount of nitrous oxide in the atmosphere.
#Safe drinking water Via Solar power Desalination Natasha Wright, an MIT Phd student in mechanical engineering, has designed a solar powered system that makes water safe to drink for rural, off-grid Indian villages.
The end result is safe drinking water that also tastes good. Earlier this year, Wright team won a grant from the United states Agency for International Development (USAID),
but Wright calculated that the amount of water used by a single farm is similar to the amount of water that a small village needs for its daily drinking water 6 to 12 cubic meters.

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.
Since the waste in the wastewater (organic material) is consumed and thus removed, the water itself becomes purified,
The wastewater comes from the local Tine dairy and is rich in organic acids, which are ideal for this process.
But this is not essential--other types of wastewater work just as well.""At the moment, we're not talking about producing large volumes of energy,
