Two-Stage AMX™ ensures stable operation and rapid recovery
AMX technology utilizes short-cut nitrogen removal reactions that combines a partial nitritation (PN) reaction that converts half of ammonia into nitrous acid and an Anammox bacteria-enabled reaction that converts ammonia and nitrite into nitrogen gas. This technology is a next-generation water treatment solution that can reduce oxygen consumption and remove nitrogen from wastewater without an external carbon source.
Applications
-
Sludge dewatering centrate (Sidestream Treatment)
Mainstream Treatment
-
Treat high-concentration nitrogenous industrial wastewater streams and landfill leachate in the most economical way
-
Use in cases where economic feasibility does not materialize when treating low C/N ratio wastewater and if you need to consider energy independence
Partial Nitritation Reactor
Partial Nitritation using dense ammonia oxidizing bacteria (AOB) granules.
- Operation with high MLSS(6,000 ~ 8,000 mg/L) inside the reactor
- Short settling time of 20 minutes(SVI less than 30)
- Maximizing partial nitritation efficiency with aerobic conditions
Anammox Reactor
Anammox reaction with dense anammox microorganisms attached to moving bed media.
- Securing high density anammox microorganisms in the reactor
- Maximizing anammox reaction efficiency with anaerobic conditions

Construction Cost and Footprint Comparison of Noksan, Suyeong, and Gangbyeon Wastewater Treatment Facilities
Provided by Busan, Korea
| Division | Noksan Sewage Treatment Plant | Suyeong Sewage Treatment Plant | Gangbyeon Sewage Treatment Plant |
|---|---|---|---|
| Required Area (m²/kg-N) | 0.52 | 7.13 | 1.86 |
| Required Volume (m³/kg-N) | 2.26 | 32.51 | 6.28 |
| Civil Construction Cost (USD/kg-N) | 565.2 | 8,129 | 1,570 |
* Civil construction cost of USD 250 / ㎥ applied
Construction Cost Reduced by
93% (Suyeong) & 64% (Gangbyeon)
Applying AMX reduces footprint and hence civil construction cost.
The AMX Advantage
Highest Nitrogen Removal Rate in the Market
Most Resilient to Upsets:
TSS, COD & Ammonia Spikes, NOB Growth
Quick start-up, restart and recovery of AOB communities
Tomorrow Water’s Unique Anammox Species: Candidatus “Brocadia Sinica” JPN1
Considered to be one of the best Anammox strains, Candidatus “Brocadia Sinica” JPN1, demonstrates excellent growth rates in both high and low substrate conditions and maintains its activity even at high salt concentrations. It achieves 2x higher growth rates and has higher salinity resistance (up to 3%) compared to other Anammox strains.
