Sidestream Treatment Technology Causes Major Savings

The Ovivo AnammoPAQ is a sidestream treatment technology that utilizes the power of the anammox bacteria to treat high-nitrogen concentration sidestreams in a compact, energy-efficient reactor. Sidestreams such as digester supernatants, centrates and filtrates present an unusual challenge of being extremely high in nitrogen concentration, often corresponding to only 1 to 2% of plant wastewater influent flow but contributing up to 30% of the nitrogen load, as these are typically recycled to the head of the plant.


The 3 R’s of Membrane Applications

Membrane bioreactor (MBR) market conditions are changing with the influx of newer companies and products. Moreover, related technologies are evolving quickly. For example, in terms of membrane equipment, Ovivo has seen overall efficiency improved at a rate of roughly 20% every two years dating back to 2001. The design of new-generation membrane products can target particular applications and or specific operating windows.

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.

Ovivo Awarded Two Municipal Contracts

Ovivo Inc. has been awarded two contracts in the U.S. municipal market, for a combined value of approximately $13 million Canadian.


Ovivo Signs Agreement With Microdyn-Nadir

Ovivo Inc. has signed a multi-year agreement with Microdyn-Nadir to service the membrane bioreactor (MBR) market. The agreement secures access to BIO-CEL membrane technology and includes a collaborative venture to build private-label membrane equipment (OVTM). Combining Ovivo system integration expertise with the Microdyn membrane manufacturing knowledge is expected to drive innovation, increase quality, reduce costs and improve delivery times.

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.

Ovivo Awarded $10 Million Contract for North American MBR System

Ovivo Inc. has been awarded a significant contract in the municipal market in North America to supply a membrane bioreactor (MBR) system. The contract value is more than $10 million and is one of many sales of MBR technology booked by Ovivo in the last two years, totaling more than $90 million. The equipment is scheduled for delivery in 2016.


Ovivo Announces 2015 MBR Operator’s Workshop

Ovivo has announced its 10th Annual MBR Operator’s Workshop, which is being held in Austin, Tex., on May 14 and 15, 2015. The workshop is open to all MBR operators, whether they use an Ovivo MBR or a different MBR technology.

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.
