Applications
A pond aeration system is not one-size-fits-all. Here is how we match blowers, microporous tubes and discs to the way you farm — with sizing guidance for each scenario.
Aquaculture ponds
The problem: Surface aerators oxygenate the top layer only — the bottom, where waste settles, stays hypoxic and breeds disease.
Our solution: Microporous tubes or discs laid on the pond bottom release fine 0.3–2 mm bubbles that rise slowly, oxygenating the full water column — including the hypoxic bottom layer.
- Bubble diameter 0.3–2 mm (FW) / 0.5–3 mm (SW) — large gas-liquid contact surface
- Works to 5 m water depth at 0.05–0.10 MPa supply pressure
- Reported energy saving of about 50% vs paddle-wheel aeration
- Self-sealing pores prevent clogging when the blower is off
Recommended system: Roots blower + microporous tube/disc array — aeration for shrimp ponds, fish ponds or RAS tanks, sized by pond area and depth
RAS & indoor farming
The problem: Recirculating systems concentrate fish waste and CO₂; oxygen demand is high and consistent, and downtime is expensive.
Our solution: Continuous fine-bubble aeration keeps dissolved oxygen stable across every tank, while airflow from the bottom lifts solids toward the drain for removal.
- Stable DO ≈ 4.5 mg/L with continuous operation
- Uniform aeration across circular and square tanks
- Low noise — no stress response in stocked fish
- Blowers can be placed on shore, outside the tank room
Recommended system: Intensive Roots blower + aeration disc arrays + galvanized canvas tanks
Wastewater treatment
The problem: Aeration basins need reliable, energy-efficient oxygen transfer for the bacteria that clean the water — with minimum maintenance.
Our solution: Microporous aeration discs deliver a dense cloud of fine bubbles that keeps activated sludge aerobic, transfers oxygen efficiently, and resists clogging.
- Suitable for municipal and industrial aeration basins
- High oxygen transfer efficiency from fine bubbles
- Low maintenance — pores self-seal when not in use
- Available in variable microporous aerator formats
Recommended system: Roots blower + aeration discs or variable microporous aerators
Live transport & high-density systems
The problem: Live seafood transport depends on constant oxygenation — mortality spikes the moment dissolved oxygen drops.
Our solution: Aeration hose can be cut to length and shaped to any tank, delivering fine bubbles with little air resistance — so a small blower keeps DO stable for hours.
- Hose cut to any length and bent to any shape
- Low energy input — a small blower serves the whole tank
- High oxygen transfer per unit of air
- Also supports high-density pond systems (≈80 kg fish/m³ reported)
Recommended system: Compact blower + aeration hose or tubes, sized to tank volume
Each application has its own oxygen demand; the aeration sizing calculator converts your figures into equipment.
Frequently asked questions
Do all four applications use the same equipment?
The same building blocks — Roots blower, microporous tubes or discs, aeration hose — but sized and laid out differently: a bottom-diffused grid in ponds, discs distributed across tanks in RAS, a floor grid in aeration basins, and hose in transport tanks.
What information sizes a system?
Water volume or area, water depth, stocking density and the dissolved oxygen you are aiming for. Tubing length and working pressure follow from those, and the blower is then chosen to deliver that airflow at that pressure.
Which application fits a farm that also sells live fish?
Live transport is its own duty — a small water volume per kilogram of fish, stressed animals and no photosynthesis to top oxygen up — so it is sized separately from the grow-out ponds rather than added to the same blower.
