Wastewater Treatment Could Have Huge Impact for Emerging Economies

Mila Luleva — Fri, 06 Sep 2013 14:16:59 +0000

Treating and recycling wastewater might be the key to solving the water scarcity problem in many countries around the world, according to new research from Japan’s Tottori University and U.N. University’s Canadian-based Institute for Water, Environment and Health (UNU-INWEH). Although the price of new treatment facilities is said to be the main reason to why […]

Olives and olive oil have been touted for centuries as part of a healthy diet, benefits including lowering blood pressure and the risk of heart disease, as well as defense against certain types of cancer. In order for these products to make it to your table, though, a certain amount of processing is required, which […]

New Wastewater Treatment Plant From Siemens Saves Energy by Using Bacterial Heat

Ovidiu Sandru — Mon, 13 Aug 2012 18:09:41 +0000

Siemens has recently invented a new biodrying process that can convert sewage sludge into usable elements – all of this while saving a great deal of energy. Thus, their “mechanically enhanced biodrying” doesn’t require any external heat source, but produces its own with the help of the microbes in the sludge, which costs about 30 […]

Wastewater-Grown Algae Yield Biodiesel and Clean the Water, Too

Finding new methods of processing wastewater really impresses me every time. Using a combination of wastewater and algae to produce biodiesel is even more touching, because it's "doubly green", as the algae neutralize water pathogens as they feed and eat out carbon dioxide to produce fuel.

Bacteria Could Make Sewage Treatment Plants Turn From High Energy Consumers to Producers

Ovidiu Sandru — Thu, 13 May 2010 19:42:17 +0000

Sewage treatment plants always consume energy to filter water (around 44 watt-hours per day per person). They use three types of bacteria and energy to pump oxygen for the first type of bacteria and methanol for the second. Adding the fact that methanol is also produced through an energy-intensive process... you can pull the conclusions.

SunPower Helps Sewage Treatment Plants Get Self Sustaining

Cristi — Mon, 11 Jan 2010 20:18:55 +0000

Wastewater treatment plants are usually packed with industrial-sized aerators, pumps and other machines that usually use a lot of electricity from the grid. But SunPower Corp. developed a solar power system for the West Riverside Wastewater Treatment Plant in Corona, California that is able to generate one-megawatt of energy

New Microbubble Production Making Biofuels and Wastewater Treatment More Efficient

Ovidiu Sandru — Mon, 11 Jan 2010 11:29:37 +0000

I didn't really actively realize that current biofuel production technologies imply the usage of fossil fuels at certain moments of the production process. This fact reduces the biofuels' credibility as a cleaner source of energy and increases their carbon footprint.

The Napa Winery Making Hydrogen from Grape Wastewater

Ovidiu Sandru — Tue, 06 Oct 2009 15:20:14 +0000

Napa Wine Company in Oakville found an interesting way of producing hydrogen by using the winery's own wastewater, using naturally-occurring bacteria and a small amount of electricity to extract hydrogen the organic material they usually throw away,with a generator the size of a refrigerator.

Wastewater Mixed With Petroleum Could Reduce Emissions by 84%

Cristi — Sat, 10 Jan 2009 20:22:32 +0000

Taiwanese scientists discovered that a new fuel can be made by combining industrial wastewater and petroleum oil. The new fuel's efficiency is increased by 14% and is a friendly way to treat industrial wastewater as well. The new fuel could eliminate the expensive treatment of industrial air emissions from boilers.
