Wilo-Sevio ELASTOX-T

Your advantages

• High flexibility of configuration owing to different lengths and wide control range of air intake
• Low-buoyancy behaviour
• Low requirements for specific piping thanks to installation of tube diffusers in pairs

Construction

Aeration system consisting of tube diffuser and pipe system to distribute the pressure. On-site downspout or air intake line can be connected directly to pipe system.

Application

For fine bubble aeration of various fluids such as drainage and sewage or sludge, for the purpose of supplying oxygen and mixing.

Equipment/function

Compressed air generators input air into the pipe system via the air intake pipe. The pipe system evenly distributes the supplied air to individual diffusers. Air is evenly input to the fluid free from coalescence via a sewage-resistant membrane.

Description/construction

The aeration system is composed of one or more aeration fields. An aeration field consists of several components.

The tube diffuser is composed of a floodable supporting tube with an overlying pipe membrane.

The pipe membrane is fixed to the supporting pipe using two fastening clips. As a result of the membrane’s good resilience, its perforation remains sealed when the membrane is not loaded. This reduces fluid entry into the pipe system.

Tube diffusers are installed on the pipe system in pairs using a tie rod. Square pipes are used for the pipe system.

The energy-efficient pipe system guarantees ideal air distribution with low levels of pressure loss. It is detachable, height-adjustable and adapted to the characteristics of the basin and other plant technology.
