The World's Largest Deammonification System To Be Provided By World Water Works For DC Water

DEMON system provides high-volume nitrogen removal with low energy usage

World Water Works, Inc., a leading designer and manufacturer of wastewater treatment solutions, has been selected by the District of Columbia Water and Sewer Authority – Blue Plains (DC Water) to provide its DEMON technology.   Once installed, it will represent the largest operating Anammox based treatment system in the world. The new DEMON treatment system, a deammonification process removes nitrogen from water at a substantially lower consumption of energy and chemicals compared to the traditional nitrogen removal processes. This application of WWW’s DEMON technology, part of a new solids processing facility at DC Water’s Blue Plains Advanced Wastewater Treatment Plant, provides a rapid return on investment and aids in the ability for DC Water to implement other innovative processes such as CAMBI.  “We are very excited about this process selection.  DC Water has been very pro-active in carefully researching, methodically testing and then implementing ground-breaking technologies.  Their leadership and others like them are helping to drive innovation in our market,” states Mark Fosshage, President of World Water Works, Inc.

The DEMON technology uses a patented and patent-pending biological process to remove high amounts of nitrogen from water. This innovative technology uses 60% less energy and produces 90% less sludge than traditional nitrogen removal processes, and unlike these technologies, does not require the use of methanol, leading to additional reduced costs. Coupling these sustainable features, with the technology’s small carbon footprint, which sequesters carbon dioxide, the DEMON system is very environmentally friendly. A unique biomass separation device maintains appropriate levels of both ammonia oxidizing bacteria (AOB) and anaerobic ammonium oxidizing (anammox) bacteria, both of which are key to the low-energy, no chemical deammonification process. This leads to greater system reliability and reduced maintenance. The process utilized by DEMON technology was nominated for the United Nations (UN) Most Energy Efficient Project Award and recently won the AAEES Sustainability award for a project at Hampton Roads Sewage District (HRSD).

As a global leader in wastewater management technology, World Water Works has installed hundreds of wastewater treatment plants. The company has an award winning manufacturing facility in Oklahoma City and has also recently replicated that facility in India to provide cost-effective technology worldwide.
