Water Treatment
AMMONIA & SULPHIDE REDUCING CONSORTIA
Welcome to our water treatment consortia catalogue. These microbial consortia biologically strip ammonia and sulphide from municipal and industrial wastewater, replacing chemical dosing with a self-sustaining, low-cost process. Deployed inside our custom Torocell WT bioreactor, they deliver reliable, continuous treatment across sewage, effluent, and aquaculture systems.
Torus Ammonia Reducer
Specifications
Deployment
Torus Ammonia Reducer is a consortium of nitrifying and heterotrophic bacteria that transforms toxic ammoniacal nitrogen in wastewater into harmless nitrogen compounds. Ammonia-oxidising and nitrite-oxidising bacteria drive a complete nitrification pathway, while facultative denitrifiers can carry nitrogen through to nitrogen gas where full removal is required. Housed within our Torocell WT bioreactor, it delivers stable, chemical-free ammonia control across municipal and industrial effluent streams.
Mechanism of Action: Nitrification: Ammonia-oxidising bacteria convert NH4 to nitrite, then nitrite-oxidising bacteria convert nitrite to nitrate. Denitrification: Under anoxic conditions, denitrifiers reduce nitrate to inert nitrogen gas for complete nitrogen removal
Key Benefits
- Reduces ammoniacal nitrogen by 80-99% across varied effluents
- Converts toxic ammonia to harmless nitrogen via nitrification
- Establishes resilient nitrifying biofilms inside the bioreactor
- Cuts chemical dosing and associated operating costs
- Tolerant of load, temperature and salinity fluctuations
- Simultaneously lowers BOD and COD in the treated stream
Suitable Applications
Proven across municipal and industrial effluent streams
Treatment Results
- →Ammonia Reduction: 80-99% removal of ammoniacal nitrogen
- →Biofilm Establishment: Stable nitrifying biofilm within 2-3 weeks
- →Operating Cost: 30-50% lower than chemical dosing
- →Operating Window: Effective at 10-35 degrees C and pH 6.5-8.5
Torus Sulphide Reducer
Specifications
Deployment
Torus Sulphide Reducer is a consortium of sulphur-oxidising and heterotrophic bacteria that removes dissolved sulphides and hydrogen sulphide from wastewater by biologically oxidising them to non-odorous, non-corrosive sulphate. It tackles the odour, corrosion and toxicity problems caused by sulphide build-up in sewers and sulphate-rich industrial effluents. Housed within our Torocell WT bioreactor, it provides continuous, chemical-free sulphide and odour control.
Mechanism of Action: Biological Sulphide Oxidation: Sulphur-oxidising bacteria convert hydrogen sulphide and dissolved sulphides to sulphate. Odour and Corrosion Control: Removing sulphide at source stops H2S off-gassing and the sulphuric-acid corrosion it drives
Key Benefits
- Oxidises dissolved sulphides and hydrogen sulphide to sulphate
- Eliminates rotten-egg odour at source
- Protects concrete and metal assets from sulphide corrosion
- Reduces reliance on iron salts and hazardous chemical scavengers
- Improves worker safety by lowering toxic H2S in headspace
- Compatible with ammonia treatment for combined effluent control
Suitable Applications
Proven across municipal and industrial effluent streams
Treatment Results
- →Sulphide Reduction: 70-95% removal of dissolved sulphides
- →Odour Control: Marked drop in H2S headspace concentration
- →Asset Protection: Reduced sulphide-driven corrosion of concrete and metal
- →Chemical Savings: Lower use of iron salts and sulphide scavengers
Torus TOC Reducer
Specifications
Deployment
Torus TOC Reducer is a consortium of heterotrophic microorganisms selected to metabolise the diverse organic compounds that drive up Total Organic Carbon in wastewater. It breaks complex carbon molecules down into simple compounds and ultimately into carbon dioxide and water, cutting TOC, COD and BOD together. Housed within our Torocell WT bioreactor, it delivers stable, chemical-free reduction of organic load across industrial and municipal effluent streams.
Mechanism of Action: Heterotrophic Oxidation: Bacteria consume dissolved and colloidal organic carbon as a food source, oxidising it to carbon dioxide and water. Broad Substrate Range: A diverse consortium degrades mixed and complex organics that single strains cannot fully break down
Key Benefits
- Reduces Total Organic Carbon (TOC) in industrial effluent
- Metabolises diverse and complex organic compounds
- Lowers COD and BOD alongside TOC
- Mineralises organics to carbon dioxide and water
- Improves final effluent quality and compliance
- Reduces sludge handling versus purely chemical treatment
Suitable Applications
Proven across municipal and industrial effluent streams
Treatment Results
- →TOC Reduction: Substantial reduction in Total Organic Carbon load
- →COD / BOD: Simultaneous lowering of COD and BOD
- →Effluent Quality: Improved compliance with discharge limits
- →Operating Window: Effective at 10-35 degrees C and pH 6.5-8.5
Torocell WT
The consortia in this catalogue are engineered to work hand in hand with Torocell WT, our custom-built bioreactor that sits at the heart of the water treatment system. It provides the ideal home for our microbes to colonise, multiply, and treat wastewater around the clock.
Why a dedicated bioreactor
Free-dosed microbes wash out of a treatment train before they can establish. Torocell WT holds a high, stable biomass of our ammonia and sulphide reducing consortia on engineered surfaces, so treatment stays consistent even as flow and load swing through the day.
How it fits the system
Torocell WT is installed as a treatment stage within the client's existing water treatment line. Wastewater passes through the reactor, where the housed consortia oxidise ammonia and sulphide before the stream moves on for polishing and discharge or reuse.
Key features
- Houses and protects our consortia for a stable, high-density biofilm
- Optimised aeration and mixing for efficient nitrification and sulphide oxidation
- Continuous, chemical-free treatment with low operating cost
- Resilient to fluctuations in flow, load, temperature and salinity
- Modular design that retrofits into existing treatment lines
- Engineered and supported in-house by Torus Biosciences
