Nanomagical Material Can Make Nuclear Reactors Safer

Nanomagical Material Can Make Nuclear Reactors Safer

Fighting cancer or making nuclear reactors that constantly self-repair themselves, helping to avoid the possibility of another Chernobyl. Clearly, nanotechnology will either save Earth or convert us into Borgs. Los Alamos National Laboratory scientists are betting on the first option. Their ne

Why Alcohol Is Good For You

Why Alcohol Is Good For You

It's one of those medical anomalies that nobody can really explain: Longitudinal studies have consistently shown that people who don't consume any alcohol at all tend to die before people who do. At first glance, this makes little sense. Why would ingesting a psychoactive toxin that increases our

Wrist-Worn, Flexible OLED Out in the Wild

The Universal Display Corporation (UDC) have themselves a wrist-worn, flexible OLED prototype that they built with support from the US Department of Defense. As you can see, the 4-inch screen looks a bit too unwieldy for practical use in the field, but the UDC believes that this technology wil

Lenovo IdeaCentre 600: Thinnest (Hottest?) All-in-One PC on the Block

Lenovo's IdeaCentre 600 is a pretty splashy debut: Its first ever all-in-one is a simple curved slab that's supposedly the thinnest all-in-one in the industry. Beyond the form factor—which borrows liberally from the new Star Trek and the iMac (the frameless black bezel looks like it was copy

Disposable Paper Laptops

Disposable Paper Laptops

I quite agree with Je Sung Park when he says that disposable cameras and cell phones have gained acceptance, so why don’t we take the next step and bring out a disposable computer. His Recyclable Paper Laptop is quite a raw version and could do with some refinement. It uses recycled paper or pul

Twitter gets hacked...again

Over the Easter weekend, Twitter fell victim to yet another attack against the micro-blogging service. This time the attacker was 17 year old Mikeyy Mooney, who claims full responsibility for the attack, saying "I am aware of the attack and yes I am behind this attack". The attack was harmless in a

Bugs Will Give Us Free Power While Cleaning Our Sewage

Bugs Will Give Us Free Power While Cleaning  Our Sewage

You might think that fresh air would be essential for a sewage treatment plant, but some bacteria cannot stand the stuff. These bugs could clean waste water so efficiently that the process could generate power rather than consume it.

In conventional sewage plants, micro-organisms digest solid waste in “activated sludge”. They convert the organic matter into methane but leave liquid waste containing ammonium and phosphates, which must be removed before the water can be poured into rivers.

Existing treatment plants use a lot of to get rid of the ammonium. The process uses bacteria that convert ammonium into nitrate, and the bugs that do this need oxygen, which must be constantly supplied to the treatment tanks by electric pumps. The nitrate is then converted into nitrogen gas by still more bugs, known as denitrifying bacteria. These require methanol, which must also be added to the mix.

This process consumes an average of 44 watt-hours per day for each person who adds waste to the sewage system. This can add up to megawatts in a big city.Cut out the middle bug

But now Gijs Kuenen at Delft University of Technology in the Netherlands and colleagues are developing a technique that cuts out the energy-consuming processes. The key is a recently discovered type of bacteria that can munch ammonia without oxygen. So-called anammox bacteria short-cut the nitrogen cycle by converting ammonium directly into nitrogen gas.

One by-product of this process is methane, which Kuenen proposes to harvest and use as fuel. The team calculates that, far from consuming energy, the process could generate 24 watt-hours per person per day. “This is about trying to make waste water treatment plants completely sustainable, in the sense that they could even produce energy, which is not the case in present treatment facilities,” says Kuenen.

This month the team will begin building a pilot plant to demonstrate the technology at the Dokhaven waste water treatment plant in Rotterdam, the Netherlands, working with from Radboud University Nijmegen and water purification firm Paques, based in the Dutch town of Balk.

Michael Wagner, a microbiologist at the University of Vienna in Austria, points out that anammox bacteria were discovered only 20 years ago and hold great promise for a new generation of sustainable waste water treatment plants. “The anammox story shows how fundamental discoveries by microbiologists can revolutionise waste water treatment,” he says.
