Using Worms to Treat Wastewater?

Traditional methods of treating wastewater – such as an activated sludge plant – have been refined over time to become very effective. A typical activated sludge plant will include screening, sedimentation, aeration, clarification, disinfection, and sludge processing. Correctly size and situate the tanks, and the regulatory authority will have no problem approving the design. If […]


Going “Brown” to Power Our Cars

Imagine a seemingly unlimited source of “clean” fuel that could be used to power our cars. Better yet, imagine that this source is normally discarded in landfills. This, of course, would be an amazing discovery. Best of all, we no longer have to imagine; this scenario has become reality. So what is the source? Sewage […]


DNA of Anammox Bacteria used for Shortcut Nitrogen Removal

Anammox bacteria is the active “ingredient” for shortcut nitrogen removal or deammonification.  The anaerobic ammonia oxidizing bacteria (“AnAOB” or “anammox”) convert ammonia directly to nitrogen gas, which is a shortcut method to traditional methods that require additional steps such as oxidizing ammonia to nitrite and nitrate (nitrification) followed by nitrate and nitrite reduction to nitrogen […]


Innovation in Wastewater Treatment Process

Glycerol is better known as a common ingredient in pharmaceuticals, foods, soaps and perfumes, but lately it’s been wandering off into new territory as a green chemistry alternative to petrochemicals. In the latest development, glycerol has been successfully deployed as the main ingredient in an innovative new nitrogen removal system at New York City wastewater […]
