#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.

If some wise guy wants to make the sewage pumps run backwards the system will shut that down.##

#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.

Through treating sewage and food that unfit for human consumption wee able to produce enough biomethane to provide a significant supply of gas to the national gas network that capable of powering almost 8500 homes as well as fuelling the Bio-Bus. Gas-powered vehicles

Roughly 75 million cubic meters of sewage and 35000 metric tons of food waste collected from households along with local grocery stores and food manufacturers is treated annually at Bristol sewage treatment works located in the suburb of Avonmouth.

and be converted to run on Bristolian sewage and food scraps o

#Quantum'entangled'light sharpens microscopes'images The first microscope that uses the eerie trick of quantum entanglement to increase its sensitivity has been developed by Japanese researchers.

#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.

or sewage can be a tedious, time-consuming process. Also, each family of bacteriophages can have a different genome organization

or extract materials is valuable for uses such as separating components of oil, gas and wastewater,

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.

#Colorado river is contaminated after mine cleanup goes wrong Workers from an environmental protection team have caused accidentally an environmental disaster releasing millions of litres of toxic wastewater into a river in Colorado.

including seawater desalination and wastewater reclamation. He says that osmotic agents often have to be at concentrations exceeding 100 millimolar to drive water movement in forward osmosis nanofiltration. f a proton gradient is used as the driving force instead,

it's capable of removing sewage and dirt from it too. The researchers combined expertise in oceanography, chemical engineering, agricultural engineering and biosystems engineering to come up with the solution

#Engineers purify sea and wastewater in 2. 5 minutes The System PQUA, works with a mixture of dissociating elements,

"We have done over 50 tests on different types of wastewater and all have been certified and authorized by the laboratories of the Mexican Accreditation agency (EMA).

or sewage can be a tedious, time-consuming process. Also, each family of bacteriophages can have a different genome organization

according to Dankovich. aw sewage was just being dumped into it, she said. The filter pages were able to bring the level of E coli in treated water down to less than 10 colony-forming units (CFU) per 100ml from an initial value of approximately 200

the university says the material is"dirt cheap"to produce meaning it could easily be used in widespread applications like lining pipes for domestic and waste water, large-scale environmental cleanup operations and even for reducing mercury levels in large bodies of water like the oceans.

The technology is effective for water having high saline content as well as for water contaminated with sewage and/or dirt,

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.

#3d-printed flutes hit the right notes Researchers at Australia's University of Wollongong (UOW) have created a number of 3d-printed custom flutes that can play microtonal tunings otherwise unachievable with standard flutes,

"a steam-powered sewage processor that burns up solid waste and creates both potable water and electricity.

That means it's large enough to continually process sewage from a community of about 100,000 people, according to the Gates Foundation.

The"fuel"used is wastewater, and the products of the process are purified water droplets and electricity.

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,

This means that the crystals can filter huge volumes of industrial wastewater, trapping large amounts of contaminants including carcinogenic material and heavy metals.

#Researchers develop catalyst to remove endocrine disruptor from wastewater Researchers from the Carnegie mellon University in US

which claimed to remove endocrine disruptor from wastewater. Researchers claimed that the tiny man-made catalysts can purify drinking water

and oxygen can remove ethynylestradiol (EE2), a contraceptive pill hormone from wastewater. Around 1, 360 sewage plants in the UK are likely to fail the European union proposed standards for EE2

according to government estimates. Upgrades for the facilities with ozone or carbon-activated treatment technology will not only involve tens of billions of Euros,

since just a kilogram of catalyst can be used to treat tens of thousands of tons of wastewater.
