OxyJet
OxyJet is a simple, low-cost system designed and manufactured by Maskoub to produce water with high, stable dissolved oxygen levels. It dissolves pure oxygen into a water spray at 2–6 bar, delivering water at 100–240 mg/L instead of about 8 mg/L in ordinary water, which is then injected into irrigation and fertigation networks or fry transport tanks.

OxyJet is based on Henry's law: the amount of gas dissolved in water is directly proportional to the pressure of that gas above the water. Water exposed to the atmosphere holds only about 8 mg/L, whereas under pure oxygen pressure the solubility limit rises more than 25-fold.
Roots respire, and oxygen in the root zone supports root respiration, nutrient uptake and beneficial microbial activity. With OxyJet, the irrigation water itself carries oxygen to the roots through the existing network.
Two diaphragm pumps
Pump water at about 108 L/h.
Pressurized oxygen
Fills the vessel headspace at 2–6 bar.
8 spray nozzles
Break the water into a fine spray inside the oxygen atmosphere.
Rapid dissolution
Pressure and a large contact area dissolve the oxygen within 2–3 minutes.
To the network
Saturated water exits through a needle valve into the pressurized line.
Key advantages
High dissolved oxygen
100–240 mg/L.
Integrates with the existing network
without changing the irrigation method.
Fry transport
Dissolved oxygen with no bubbles on the gills.
Compact wheeled unit
For the field or on the transport vehicle.
Simple and low-cost
Locally available parts.
Egyptian design and manufacture
Local technical support and maintenance.

Comparison with conventional systems
| Parameter | Bubble diffuser (air or oxygen) | OxyJet |
|---|---|---|
| Form of oxygen | Bubbles rise and escape to the atmosphere | Dissolved in the water |
| Achievable concentration | Close to atmospheric saturation ≈ 8 mg/L | 100–240 mg/L in the outlet water |
| In fry transport | Bubbles may stick to the gills | Oxygen reaches the gills in dissolved form |
| In irrigation | Bubbles cannot be carried through the network | Injected into the pressurized irrigation line |
