The working principle and advantages of an oxygenator

Oxygen generators are widely used in modern aquaculture. So, what exactly is an oxygen generator? How does it work? And what are its advantages? In this article, we’ll provide detailed answers to these questions and introduce you to some reliable oxygen-generator suppliers.

An aerator is a device that uses an electric motor to rotate an impeller, compressing air and delivering it into the water through pipes. When the air enters the water, it releases oxygen in the form of bubbles, thereby increasing the oxygen content of the water. This process is known as aeration.

The working principle of an aerator is very simple, yet its advantages are unmistakable. First, an aerator can increase the oxygen content in water, thereby improving water quality. This is particularly important for aquaculture, as water quality directly affects farming efficiency. Second, an aerator can boost the concentration of dissolved oxygen in water, which in turn promotes the metabolism of aquatic organisms, fostering their growth and health. Finally, by increasing the oxygen level in water, an aerator helps prevent diseases and mortality among aquatic organisms, thus reducing losses.

If you’re looking for a reliable oxygenator supplier, here are some recommended suppliers:

1. Shenzhen Chuangxinyuan Environmental Protection Technology Co., Ltd.: Chuangxinyuan is a company specializing in the R&D, manufacturing, and sales of environmental protection equipment. Its oxygenating devices feature high efficiency, energy savings, and durability.

2. Suzhou Xinhua Environmental Protection Technology Co., Ltd.: Xinhua Environmental Protection is a company specializing in the R&D, manufacturing, and sales of environmental protection equipment. Its oxygenators feature quiet operation, high efficiency, and intelligent functionality.

3. Shenzhen Tianlida Environmental Protection Technology Co., Ltd.: Tianlida is a company specializing in the R&D, manufacturing, and sales of environmental protection equipment. Its oxygenators feature low noise, high efficiency, and energy savings.

In short, aerators play a crucial role in modern aquaculture. If you’re looking for a reliable aerator supplier, be sure to choose a well-known brand to ensure quality and performance.

The China International Fisheries Expo is one of the world’s largest and most influential international trade fairs in the global aquaculture industry, having served the global aquaculture sector for 25 years. Since its inception in 1996, the expo has effectively integrated diverse, global, end-to-end industry resources—from aquatic product trading and related technologies and processing to cold-chain logistics, food and ingredients, catering and hospitality, as well as consulting and investment—into the Chinese market.

The relationship between water convection and dissolved oxygen levels in aquatic bodies: The introduction of an aeration device can effectively regulate dissolved oxygen levels.

Although fish floating to the surface can be caused by a variety of factors, in addition to excessive stocking density, overloading the total fish biomass, and poor water quality, the convective properties of water are also a major factor that cannot be overlooked. Simply put, when water temperature is low, its specific gravity (or density) increases, causing it to sink; conversely, when water temperature is high, its specific gravity (or density) decreases, making it float upward. Understanding and mastering the principles of water convection will greatly facilitate the smooth operation of aquaculture. On warm days, after being heated by the sun during the day, the warmer, lighter water tends to stay on top. As the sun sets and the air temperature begins to drop, the upper layer of water cools down, increasing its density, and gradually starts to sink. If the nighttime temperature remains relatively high, the water cools down slowly, and the upper layer won't reach the bottom of the pond until early morning. This is one of the main reasons why oxygen levels tend to drop sharply from late night into early morning on hot days. However, if a heavy rainstorm occurs in the evening, the situation changes dramatically. The cold, heavy rainwater quickly sinks to the bottom of the pond, stirring up sediment, leftover feed, fecal waste, biological residues, and other organic matter from the pond bottom and bringing them into the middle and upper layers of the water. These harmful organic substances rapidly deplete the dissolved oxygen in the water. Before dawn even breaks, the dissolved oxygen in the water may be completely used up, leaving the fish vulnerable to oxygen depletion and causing them to float to the surface—a phenomenon known as "floating and surfacing." Therefore, sudden heavy rainfall in the evening or at night can also lead to oxygen depletion and fish floating to the surface.

How to choose an aerator?

Oxygenators are used to increase the oxygen content of water bodies. There are many types of oxygenators available, including impeller-type, paddle-wheel type, aeration-type, air-injection type, spray-type, and jet-type oxygenators. Oxygenation helps save fish and ensures high yields. According to measurements, each ten-million-unit impeller-type oxygenator can add more than 1.8 kilograms of oxygen to the water per hour—enough to meet the respiratory needs of several tons of fish for an entire hour—and can promptly address oxygen deficiency in pond fish. After using oxygenators, the production conditions of fish ponds have shifted from natural ecosystems to artificially controlled ecosystems, thereby breaking through the limitations on fish yield imposed by still-water ponds under natural conditions.
