Wilo-Sevio ELASTOX-P

Series description

Your advantages

  • Increased operational reliability thanks to hoist restriction of the plate membrane to evenly expand the membrane for ideal air intake. Thanks to its special design the air intake reduces fluid penetrating the pipe system when the membrane is not loaded
  • Specific airflow rate generates higher air intake
  • Low requirements for specific piping thanks to installation of plate diffusers in pairs
  • High quality and service life of the diaphragms owing to manufacture as moulded product

Construction

Aeration system consisting of plate 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 plate diffuser consists of an arched support plate with overlying plate membrane. The plate membrane is attached to the support plate using a fixation frame. A link along the structure in the fixation frame serves as the hoist restriction.

Thanks to the hoist restriction the membrane expands evenly, thus guaranteeing ideal air intake. Its special design reduces fluid penetration to the pipe system when the membrane is not loaded. As a result of the membrane’s excellent resilience, its perforation remains sealed when the membrane is not loaded.

Plate diffusers are installed on the pipe system in pairs using a tie rod and sealing washer. 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.
