Ball diffuser K1à K3

A ball diffuser in aquaculture is an aeration device used to oxygenate the water in ponds, tanks, fish farming systems, and aquariums.

General features

• Shape: spherical or semi-spherical.

• Material: usually porous ceramic, sintered glass, microporous plastic, or special rubber.

• Operation: air (or pure oxygen) is injected into the sphere through a connector and released through micro-perforations.

Principle

• Air is broken down into microbubbles (1–3 mm on average).

• These bubbles provide a large exchange surface between air and water, improving oxygen dissolution.

• The slow ascent of microbubbles extends their contact time with water → higher aeration efficiency.

Advantages in aquaculture

• Efficient oxygenation to maintain optimal dissolved oxygen levels, essential for fish health and growth.

• Homogeneous distribution of air in the water column.

• Easy installation: direct connection to a compressor or air pump.

• Durability: resistant to shocks and corrosion.

• Can also provide gentle water mixing, limiting thermal stratification and improving overall water quality.

Applications

• Fish farming ponds or recirculating systems.

• Hatchery tanks.

• Temporary fish holding (transport or waiting tanks).

• Aquariums and small experimental setups.
