O2-JETER® Aerator (also called O2-JETER® Sub-surface Aerator, O2-JETER® Aspirator Aerator) deliver excellent oxygen transfer and high mixing efficiency to a wide range of wastewater treatment processes in any climate. From extended aeration and activated sludge processes to lagoons and oxidation ditch applications, the O2-JETER® aerator’s rugged but efficient design maximizes treatment performance while minimizing energy consumption. This unique product mixes and aerates all or part of a basin.

O2-JETER® Aerator is a high quality, minimal maintenance aspirator aerator with proven, superior performance… all at an economic price. For over years, aquaculturists worldwide have experienced the many benefits of the O2-JETER® Aerator for their aquatic applications.

 

How the O2-JETER® works

  • O2-JETER® Sub-surface Aerator

    O2-JETER® Aerators deliver excellent oxygen transfer and high mixing efficiency

  • O2-JETER® Aerator

    O2-JETER® Aerator (also called O2-JETER® Sub-surface Aerator)

The O2-JETER® Aerator operates by creating a partial vacuum under the water, drawing air through the shaft and dispersing the oxygen into the water in a horizontal direction. As the propeller rotates, it induces a flow of atmospheric oxygen through the air intake ports on the shaft located above the water surface. This air is then drawn through the shaft, past the propeller, and exits in a high velocity stream of fine bubbles as it is diffused into the water.

Oxygen is transferred to the water and biomass during the contact time with the fine bubbles. The combination of the unit's propeller design and horizontal mixing produces total oxygen dispersion, optimizing the wastewater treatment process, dissolved oxygen in aquaculture.

  • Low dissolved oxygen in the water can cause deaths in shrimp and fish

  • Oxygen dispersion is key!

    The most important element when selecting an aerator for aquaculture usage regardless of the application is oxygen dispersion. Oxygen dispersion involves both thorough subsurface circulation and oxygenation to create a destratified pond environment where temperature and oxygen levels are uni-form throughout the entire pond. This concept is of the utmost importance to all aquatic species as it fosters a healthier environment that will lead to increased size, increased survival and thus increased profit to the aquaculturist. Since species like shrimp are bottom dwellers, it is critical to have the oxygen distributed to the bottom layer of the pond where these species live and thrive. Also, thorough mixing and distribution of oxygen aids in the control of animal and feed wastes, keeping pond bottoms cleaner and decreasing risks of disease..

    The O2-JETER® Aerator is the most technologically advanced aerator in the marketplace today which is capable to accomplish both mixing and oxygenation in one single unit due to its superior design which has been based on high quality.

 

The Importance of fine bubbles and water current

Good food management is not the only factor required to insure that the shrimp grow well. If the amount of dissolved oxygen (DO) in the pond is too low, the shrimp will eat less and there will be more left over food. This will affect other parameters of water quality, and if the water quality drops the shrimp will get weak and more susceptible to bacterial infection. Such conditions lead to low survival rates.

In the past, bacterial infection was seldom a problem with Pacific White Shrimp culture. This indicates that there is something wrong or something lacking with the aquaculture management practices used at present. Usually it is a problem with overfeeding. Excess feed causes a build up of waste materials in the pond, which encourages the growth of disease-causing Vibrio bacteria. When the oxygen or DO level in the pond drops over the course of the culture period, the shrimp are likely to get sick.

On the intensive shrimp farms in Thailand, most farmers install at least 36 HP of aerators per hectare to be sure that there will be enough water current to keep the bottom of the pond clean in the feeding areas. The sediment is all swept towards the center of the pond.

Farms that are successful in keeping the DO at no less than 4 ppm even in the morning are usually very successful, with good growth rates, a high survival rate and a low FCR. When the DO is maintained at at least 4 ppm, there is seldom a problem with white feces disease or bacterial infections. In contrast, on farms where the DO drops below 4 ppm at night, the shrimp will grow slowly during the culture period and white feces disease is very common.

The O2-JETER® Aerator's speed is as fast as the Paddle wheel aerator. The position of the propeller is adjustable from the water surface to the pond bottom for emergency and long terms aeration, increased mixing and oxygen dispersion, no dead space,

 

Best position for an O2-JETER® Aerator

Use the Paddlewheel Aerator to create strong water current and move deep and super high dissolved oxygen producted by the O2-JETER® Aerator to the whole pond. Perfect dissolved oxygen level and water circulation.

The O2-JETER® Aerator + Paddlewheel Aerator is the best aerating combination that increase biomass at least by 30%.
