The global demand for seafood continues to increase over the years, generating the need for new technologies to improve production processes. Fish farming has emerged as an answer to satisfy seafood requirements, but also to protect oceans from overfishing, contributing to producing healthy food and guaranteeing a better feed conversion rate, resulting in a more efficient process.

Dissolved oxygen availability is the key to ensuring successful fish farming. Fish absorb oxygen through direct contact with water, turning this element into a fundamental condition to achieve good results in aquaculture.

Factors such as air pressure, hydrostatical pressure, and salt content directly affect oxygen solubility.

Although fish farming is commonly focused on water temperature control only, this trend has recently switched within intensive culture systems where water oxygenation is even more relevant. Besides protecting farmers’ stocks, optimal oxygen levels ensure growth by improving fish appetite, but it also helps to control water temperature avoiding stress in fish.

Aero-Tube Hose to ensure oxygen availability

Aero-Tube Hose represents a major advancement in aeration technology.

Developed by innovation experts at Swan, the blue stripe Aero-tube Hose is a dual-patented aeration hose that works as a whole with an air supply to deliver oxygen to water. 

“Oxygen smoothly permeates through its micropores.” 

By creating a vast number of microbubbles in the water, at an average size of 3 mm each, it is possible to maximize the water surface area improving oxygen transfer getting higher rates than conventional aeration systems.

This blue stripe hose versatility allows it to operate at maximum capacity with both regenerative blowers and linear air pumps, guaranteeing an optimal airflow of 2.2 m3/hr/m (0.4 cfm/ft) if recommended length for intake on one (2-3m) or both sides (4-5m) is not exceeded.

Moreover, the blue stripe should be positioned face down for better performance. Besides, the hose should be fastened or weighted, and the hose end can be sealed or fitted with a plug and clamp.

How does Aero-tube

Hose works?

It is a rubber/polyethylene diffuser hose with an antimicrobial coating that reduces fouling and blockage, providing significantly higher oxygen transfer rates which induce higher dissolved oxygen levels. These features added up to low start-up cost, low replacement costs, and maintenance, leading to efficiency in production, and energy costs savings by up to 75 percent.

Despite the hose thick and porous walls, it is highly flexible and durable with an antialgal and antimicrobial material that requires no chemicals to be added during cleaning, offering a long-lasting system.

Aero-Tube Grid, combining systems to get better results

Aero-Tube Grid is an engineered system created to get the most out of aeration tubing. It is an injection molded HDPE plastic frame combined with 20.1 m (66 ft) of blue stripe Aero-Tube Hose.

The Hose is attached to the aeration grid with stainless steel clamps, turning it into one solid system ready to be plugged into an air supply to infuse up to 300 m3 /hr of air into water. It is the most convenient way to implement a low-cost and highly efficient AeroTube oxygenation system.

Due to its flexibility and durability, the Aero-Tube Grid can be used in an extensive range of applications, from aquaculture to wastewater treatment. The system can resist up to 7kPa of airflow and 44m3/hr air pressure. It holds the antialgae and antimicrobial feature the hose also offers and will not break if someone accidentally stepped on it.
