Since Paques pioneered the first Anammox based nitrogen removal system in 2002, ANAMMOX ®has become the worlds most used high rate nitrogen removal system. You can also profit from the most efficient nitrogen removal system on the market: ANAMMOX® offers a treatment capacity of over 160.000 kg nitrogen per day.
Why choose ANAMMOX® as your nitrogen removal system?
The ANAMMOX® conversion is an elegant shortcut in the natural nitrogen cycle. Anammox bacteria convert ammonium (NH4+) and nitrite (NO2 -) into environmentally neutral nitrogen gas (N2).
The currently patented Paques one-step ANAMMOX® technology combines partial nitritation (conversion of ammonium into nitrite) with the ANAMMOX® process. The ANAMMOX® process operates with naturally grown concentrated granular sludge in which optimal conditions for microbial synergy are created.
Applications of ANAMMOX®
The ANAMMOX® process can be used for the removal of ammonium from nitrogen rich effluents. It is often applied after anaerobic treatment of sludge or wastewaters.
For example in:
Municipal wastewater treatment (sidestream)
Industrial wastewater treatment
Advantages of the ANAMMOX® process
The main potential advantages of the ANAMMOX® process as compared to traditional biological treatment are:

Q&A
What is ANAMMOX®?
ANAMMOX® is a side stream nitrogen-removal application that treats concentrated side streams from anaerobic digestion dewatering before they impact the main biological treatment process.
Why is the side stream important if it represents such a small amount of flow?
The side stream can represent less than 1% of total plant flow while contributing 30% or more of the nitrogen load returning to the main process. Treating this concentrated load before it returns can reduce the burden on the main treatment process.
Why is controlling the recycle nitrogen load important for discharge permits?
If the recycle load overwhelms the main biological treatment process, it can create process stability issues and concerns with discharge quality and permit compliance. Treating the recycle load makes the main process more stable and reduces this risk
What does ANAMMOX® change?
ANAMMOX® side stream treatment reduces the recycle load by approximately 90–95%, resulting in a 25–30% net reduction to the main process. It does so without consuming carbon and with approximately 50% less energy demand.
What are the main benefits for a municipal wastewater facility?
The primary benefits are lower operating costs, more available main-process capacity, lower energy demand, a smaller footprint and improved process stability, helping the plant consistently meet its discharge requirements. Cost and capacity as the primary value.
How does ANAMMOX® compare with conventional nitrogen removal?
Conventional nitrification and denitrification require carbon, aeration/energy and alkalinity. ANAMMOX® side stream treatment reduces the recycled load without consuming carbon and with approximately 50% less energy demand.
Is ANAMMOX® suitable for existing plants?
YES as it is a side-stream solution alongside an existing main treatment process. Its small footprint and reduced tank-volume requirement make it easier to retrofit into existing facilities.
How reliable is ANAMMOX®?
ANAMMOX® has been operating since 2002, demonstrating up to 90%+ nitrogen removal efficiency and operation under varying load conditions. Paques has 75+ installations globally and the largest installed capacity in the market for total nitrogen load removal: 385,000 lbs N/day.
How do I know whether ANAMMOX® makes economic sense for my plant?
It depends on the specific plant situation. Paques can evaluate the customer's case and compare the current approach—including chemical, energy and capacity considerations—with an ANAMMOX® solution to develop the specific payback/business case.
How can I get a customized ANAMMOX® assessment?
Talk to the Paques team. Paques experts can review the specific plant situation and build a tailored case to evaluate the potential benefits, costs and payback for that facility.
