But western-style toilets require sewage lines and treatment plants that aren feasible in many places.
The Omniprocessor, designed by Seattle-area engineering firm Janicki Bioenergy, reinvents the sewage treatment plant. In the Omniprocessor, sewer sludge is fed into tubes
and boiled, producing water vapor which is purified for drinking. The dry solids are fed then into a fire,

with the aim of strengthening Europe response to water management and to directly engage with citizens and communities on the front line.
A citizen observatory When it comes to floods, citizens have often been thought of as mere consumers of information;
and become part of the solution to better water management? This is why Wesenseit is developing the concept of a citizen-based water observatory,
New technologies and approaches to water management are being tested and validated in three EU countries: the UK, The netherlands and Italy. or example, we are developing mobile apps

#Flood alert Dams that protect urban areas from flooding sometimes fail, resulting in catastrophic damage. But what can be done to prevent such disasters?
here are 48 sensors constantly telling us how this dam is feeling and how it behaving.
This technology makes this the smartest dam in the world. The underground sensors, developed within a European union research project, transmit measurements to data centres in several countries.
This device measures the amount of water in the dam and many other parameters such as the underground temperature,
and the movement of the sensors inside the dam. These indications can be followed in real time using any internet-enabled device.
or three times a year we got people viewing the asset the dam from a visual point of view.

a Senior Flood Management Engineer, at HR Wallingford, said: his system will allow to show you the outline of the flood mapping;
Using tap water, it was tested on excavation equipment and went beyond any initial expectations.""All the components passed the functional tests,
#A European Flood Alert System to protect Europe's cities In 2010, when a big flood hit Poland, the Czech republic, Germany, Hungary, Slovakia and Serbia, the situation was quite different.
National authorities had improved their communication strategies between the countries. Furthermore, EFAS allowed for combined efforts to result in an overall much more efficient response to the crisis."It was a big success for EFAS;
floods were forecast and flood alerts were issued well in advance"says Jutta Thielen del Pozo, a meteorology researcher who leads EFAS at the JRC.
These partners can also consult the EFAS Flood Portal on a daily basis. The portal issues maps of Europe where danger zones are indicated by"hot spots".
And when these data reflect a danger for floods, EFAS informs the partners. In 2011 EFAS issued 9 alerts.
It is equipped with a sensor that accurately monitors the concentration levels of copper and silver ions in water sources and facilities
#Aquaszero#New product to make drinking water safer Aquaszero New product to make drinking water safer Arsenic may be found as a water
Fotolia, 2012 Drinking water with high arsenic levels leads to skin diseases and disorders in blood vessels. It gradually evolves into cancers that can attack the bladder,
but two types of arsenic are found in drinking water. One type of arsenic (As V) is removed easily,
Known as Aquaszero, the product can be used in existing water treatment filter cartridges where the arsenic bonds firmly to the Aquaszero granules.
Behind the development is led by a consortium Loufakis Chemicals SA in association with three SMES involved in water engineering,
Loufakis Chemicals SA expects that this low-cost material will be used widely as the adsorbent media in new water treatment plants,
and may replace the conventional materials in existing water treatment systems. It can be applied in water treatment for both industrial and domestic use."
"In many parts of the world the permitted limits set by the World Health Organisation (WHO)
"The most severe problems with arsenic contamination in the world are found in Bangladesh where more than 95 percent of the water supply for more than 138 million people is contaminated potentially at levels exceeding permitted international limits.
A low-cost solution can be the use of Aquaszero filters to treat the drinking water, "adds project coordinator Koukiotis.
European researchers and their international partners have developed a new way to purify drinking water, dubbed the amily filter'because of its ease of use and affordability for even the poorest families.
In Bangladesh alone, up to 44%of the population is exposed to arsenic-laced drinking water, the World Health Organisation (WHO) estimates.
Thankfully, European researchers and their international partners at UNESCO's Institute for Water Education (IHE) in Holland have perfected a simple, efficient and importantly low-cost water filtration device
which removes arsenic from contaminated drinking water. The filter uses iron oxide-coated sand which absorbs the arsenic from water at the oint of use
rom the very beginning, it was clear to us that a oint of use'system was the only feasible approach in the short term for rural areas of developing countries with no piped water supply,
The iron oxide-coated sand is a by-product of large-scale water treatment initially, it will have to be imported into the countries with no equivalent treatment plants in built-up areas it needs no added chemicals,
These have helped stretch water supplies and have been so successful that many areas of the state are using about the same amount of water today as they were 10 and 20 years ago, even with population growth.
Replacing these toilets with high-efficiency toilets or dual flush toilets, not available years ago, can save California

#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.
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
Sludge is a semisolid by-product of wastewater treatment and reducing the amount produced has huge environmental and economic benefits. ur treatment produced only a fraction of the sludge that a conventional lime-based method would have allowed
Given the Australian mining industry is estimated to generate hundreds of millions of tonnes of wastewater each year,
the technology opens a significant opportunity for companies to improve water management practices and be more sustainable. he technology can produce a material high in metal value,
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
the treated water can be purified much more efficiently via reverse osmosis and either released to the environment
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.
The property is also five times more water-efficient than the normal house, with low-flow fixtures and short-run hot-water pipes.
Street lamps kept aglow by sewage sludge. An entire town filled with chicken manure-heated homes. The latest initiative in England that's transforming landfill-bound organic waste and excreta into bio-based fuel?
That is the conversion of waste n this case both locally sourced food waste and human sewage nto a methane-rich biogas.

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

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.
They shopped their phages to bacteria-plagued industries such as oil and water treatment, where biofilms build up in pipelines before seeing firsthand that the food industry as in desperate need of new detection technologies.
