Technology
The GBT-M reactor combines the strengths of continuous stirred-tank (CFSTR) and plug-flow (PFR) reactors in a vertical multi-stage design, shortening treatment time for high-strength organic wastewater and raising organic removal efficiency.
Wastewater and air entering the nozzle accelerate rapidly, and the strong rotational force creates a vacuum at the tip of the air inlet.
The vacuum draws in large volumes of air, which collide with the wastewater in two mixing chambers and form microbubbles a few hundred micrometres across.
The microbubbles contact the mixed liquor over a large area, maximising oxygen dissolution while also diluting and mixing.
Suited to very concentrated effluent such as food waste leachate.
High-load operation needs only 1/5–1/20 of a conventional tank’s area.
Fits even shallow existing tanks and relieves reactor capacity shortages.
No machinery inside the reactor means fewer breakdowns and easy repair.
Stainless steel or PE nozzles last for years and supply oxygen steadily.
High MLSS and recirculation dilution limit the impact of toxic or shock loads.
Our unrivaled, specialized microbial technology and operating know-how reduce odor.
| Criteria | GBT-M reactor | Conventional aeration tank |
|---|---|---|
| Reactor design | Enclosed PFR, vertical multi-stage (3–20 m deep) | CFSTR (4–5 m deep) |
| Bubble size | Microbubbles of a few hundred µm | Disc diffusers, up to 1 mm |
| Oxygen transfer rate | 3–10 kgO₂/kW·h | 1.2–2.0 kgO₂/kW·h |

| Footprint | 1/5–1/20 of a conventional tank | Large area required |
| MLSS | Above 5,000 mg/L | 1,500–5,000 mg/L |
| TKN volumetric loading | 0.4–1.2 kg/m³·d | Up to 0.06–0.2 kg/m³·d |
| Shock loads | Little impact thanks to high MLSS and recirculation | Risk of microbial shock and shutdown |
| Ease of operation | Relatively simple to run | Needs experienced specialists |
| Removal efficiency | BOD above 95%, nitrification above 99% | Struggles with high organics and nitrogen |
Activated silicates and humic substances create a soil-like environment in which fungal hyphae and microbial binders knit fine particles into stable, water-resistant aggregates.
These aggregates have a high cation-exchange capacity: they capture nitrogen and stop ammonia odor at the source, while chelating metabolites remove other odorous compounds.
As beneficial soil microbes dominate, putrefying bacteria decline, preventing odor from decay in the first place.
Solid–liquid separation → odor control and water treatment → discharge: the HAYEON GLOBAL livestock manure process
