LEAKY PIPE AERATION

Leaky Pipe Aeration

A.G.A both supply and install a range of pipes and frames for aeration which have applications within the fish farming industry. The ‘leaky pipe’, placed at a low point in the water body relies on compressors or blowers to supply air which enters the water through diffusers.

Leaky pipe systems should be specifically designed to suit the water body in question and are particularly useful in the transportation of fish, providing a viable solution to aeration of containers while in transit. Ask our consultants for advice on design.

We can supply and install a range of tough porous rubber hoses for aeration and other gaseous exchange applications. This technique has many applications and can be used within the fish farming & fish transportation industry; pollution control; effluent/leachate treatment and associated uses where high exchange rates are required.

The system relies on compressors or blowers to supply high or low-pressure air, which enters the water through the diffuser. The diffuser is placed at a low point in the water body where it splits the air into small bubbles; this is achieved with numerous types of porous materials.

Oxygen is transferred from the air bubble to the water as the bubbles pass through the water column, the smaller the bubble the larger the surface area, thus better oxygen exchange rate. The distance and speed the bubble travels through the water column also impacts on the efficiency of exchange, the greater the contact time the greater the exchange.

Partial pressure dictates that the dissolved oxygen deficit will ultimately control the rate of exchange to a great extent in air systems.

When oxygenating a pond or lake the traditional continuous length of leaky pipe can often be omitted from the design in favour of a leaky pipe module, these systems should be specifically designed to suit the water body in question.

A leaky pipe system is particularly useful in the transportation of fish and provides a viable solution to aerating containers while in transport.
