Oxygen Generator For Aquaculture

Why choose NEWTEK oxygen generator for Aquaculture?

 

►Pure oxygen stability: Continuous oxygen supply to avoid fish stress or water quality deterioration.

►Intelligent control and IoT integration:It supports remote real-time monitoring of key parameters such as dissolved oxygen content and water temperature, and automatically adjusts oxygen output, making it possible to control oxygen enrichment equipment via mobile phone.

►Modular design: NewTek provides flexible production capacity configuration of 3-200Nm³/day, adapts to 220V power supply and does not require infrastructure modification. It can integrate ozone sterilization module to achieve comprehensive water quality control.

►Technical support and customized services for the entire industry chain: NewTek provides full-cycle services from equipment selection to system integration, and supports linkage with circulating water treatment equipment such as microfiltration machines and biochemical reactors. The RAS solution combines the "PSA oxygen production + ozone sterilization + online monitoring" modules to achieve a water recycling rate of more than 95%. At the same time, corrosion-resistant materials and pressure adaptation solutions can be customized for special environments such as plateaus and high salt.

Typical application scenarios and locations

 

The equipment is widely used in factory-scale circulating water aquaculture systems, fish hatchery ponds, high-density aquaculture ponds and temporary aquarium systems.

In the aquaculture of high-value aquatic products such as shrimp and salmon, pure oxygen aeration is used to increase the dissolved oxygen in the water to a supersaturated state (>5mg/L), significantly shortening the aquaculture cycle and increasing the density.

In the transportation of live fish and intensive fish farming scenarios, the oxygen generator can provide a continuous oxygen source for closed water tanks to reduce transportation losses. It can also be used to match the ozone generator to achieve water disinfection and sterilization to form a healthy aquaculture environment.

Solution and value

 

 

Modern aquaculture integrated systems usually link oxygen generators with circulating water treatment equipment. Typical configurations include: PSA oxygen generators, turbine fans, oxygen cone diffusers, protein separators, sand filters and ultraviolet sterilizers.

NEWTEK supports the equipped dissolved oxygen automatic control system, which controls the oxygen output pressure (0.2-0.3MPa) in real time through the online monitoring module, and cooperates with the ozone generator to achieve double water purification. The other circulating water system integrates oxygen generators, microfiltration machines, and biochemical reactors to form a complete ecological chain from oxygen supply, solid-liquid separation to biological filtration.

Compared with traditional liquid oxygen tanks or oxygen bottles, on-site oxygen generation equipment can reduce operating costs by 30%-50%, and the daily processing capacity of a single device can reach 200Nm³, meeting the needs of 5-20 acres of fish ponds. In the case of Norwegian salmon farming, the production was increased by 3-5 times with the pure oxygen enrichment of deep-water cages.

The equipment can also be adapted to farms of different sizes through modular expansion (such as 3L-200L/Min flow adjustment), especially in areas where tropical storms are frequent, to ensure the stability of the oxygen supply system and reduce the risk of mass death due to lack of oxygen.

FAQ

Q: What is the core role of the oxygen generator in the fish fry hatching scenario?
A: In the fish fry hatching pond, the oxygen generator distributes pure oxygen evenly to the water body through a micro-nano bubble diffusion device (such as an oxygen cone) to ensure that the dissolved oxygen content is stable at 6-8 mg/L during the hatching stage. A high dissolved oxygen environment can increase the survival rate of fish fry by more than 30%, while inhibiting the reproduction of anaerobic bacteria in the water body and reducing the generation of harmful substances such as ammonia nitrogen and hydrogen sulfide.

Q: How to use the oxygen generator to reduce losses in the live fish transportation scenario?
A: In a closed live fish transportation water tank, the oxygen generator can adjust the oxygen output pressure (0.2-0.3MPa) in real time, and form microbubbles with a dissolved oxygen efficiency of 90% through a microporous aeration tube or a high-pressure ejector, maintaining the dissolved oxygen ≥8mg/L throughout the transportation process, and reducing the live fish transportation loss rate from 15% to less than 5%.

Q: How to integrate the oxygen generator with the circulating water treatment system (RAS)?
A: Typical RAS integration solutions include:
PSA oxygen generator: provide the main oxygen source;
Ozone generator: combined with oxygen generator to achieve water sterilization (ozone concentration 0.1-0.3mg/L);
Microfiltration machine + biochemical reactor: remove solid impurities and degrade organic matter;
Online monitoring module: real-time regulation of dissolved oxygen, pH value and other parameters. For example, Xiamen Chongrui's RAS system achieves a 95% recycling rate of aquaculture water through linkage control.

Q: How can small and medium-sized farms achieve low-cost and efficient oxygen supply through oxygen generators?
A: For small and medium-sized aquaculture, NEWTEK oxygen generators have dual towers and modular design to ensure the convenience of mobility, and we support on-site installation and refuse complicated and cumbersome operations. Through modular design and IoT control, the power consumption cost is 50% lower than that of liquid oxygen tanks, and there is no need to frequently replace molecular sieves.
