Sustainable Nitrogen Removal Process Uses Less Oxygen

The Anammox conversion is an elegant shortcut in the natural nitrogen cycle. Anammox bacteria convert ammonium (NH4+) and nitrite (NO2-) into nitrogen gas. Paques developed the process for commercial purposes in cooperation with Delft University of Technology and the University of Nijmegen. Since the first full-scale plant started up in 2002 with treatment of a side stream of sludge digestion, many other Anammox plants have been installed and are running successfully.

Membrane Bioreactor Bolsters Reuse Efficiency

Nestled in a valley between the Pukalani Country Club’s golf course and a surrounding residential community in Maui, Hawaii, is the Pukalani MBR Water Reuse Facility, a state-of-the-art membrane bioreactor system (MBR) producing R-1 water reused to irrigate the golf course. 

Prior to its startup in October 2010, the Pukalani STP was in a state of serious disrepair. The concentric circular steel tank was in such poor condition that the design and construction of the MBR was fast-tracked to ensure treatment was not interrupted.

Destination: Wastewater Processing

The hospitality industry has made great strides in managing water consumption and finding new ways to reduce operating costs and shrink its members’ environmental footprints. The U.S. Environmental Protection Agency estimates that approximately 15% of the total water use in commercial and institutional facilities in the U.S. takes place in hotels and other lodging businesses. As the industry continues to advance the agenda of sustainability with a greater focus on water and wastewater stewardship, it is producing viable solutions to help manage wastewater goals and challenges.

Membrane Bioreactor Lowers Operational Expenses in Washington

In 2010, the city of La Center, Wash., retrofitted its sequencing batch reactor (SBR) with a membrane bioreactor (MBR), using as much of the existing tankage, equipment, buildings and other onsite systems as possible. Since then, the MBR has cost the city approximately 15% less than the SBR in terms of its total operating expenditures (OPEX), even though the flow to the plant increased by 15%.

Flat Plate Membrane Bioreactor Provides Higher Effluent Quality

In 1997, the U.S. Environmental Protection Agency (EPA) issued a five-year Filtration Avoidance Determination (FAD). The determination required New York City to acquire environmentally sensitive land in the New York City watershed, adopt strong watershed rules and regulations and institute and maintain a comprehensive watershed protection program.

MBRs Big & Small

In Canton, Ohio, a few weeks after ringing in 2014, four contractors submitted bids to update an aging extended aeration wastewater treatment plant (WWTP). Based on bid numbers, it will cost about $80 million to upgrade the 42-million-gal-per-day (mgd) plant to a membrane bioreactor (MBR), or less than $2 per gallon of water treated.

MBRs for Cost-Effective Wastewater Treatment

Membrane Bioreactors (MBR) may have a reputation for being costly, but they do not have to be.

A survey of 137 MBRs in the U.S. showed that an Enviroquip MBR using flat plate technology is typically half to three-quarters the CAPEX cost of other MBR suppliers. CAPEX is certainly important, but what about OPEX?

While there is a tremendous amount of data publicly available on energy and chemical consumption of MBR systems, there is little to no data published on labor requirements of these systems.
