The INVENT TEX-FLEX®-Aeration System with its extremely durable textile membrane specifically for the use in deep basins, as well as for media in which conventional membrane materials are not suitable.
TEX-FLEX®-Aeration System
Product Information
The TEX-FLEX®-Aeration System was especially developed for use in problematic wastewater. It consists of one or more aerator grids connected to the main supply line at the basin edge via a common pipeline.
The combination of a rugged stainless steel body enveloped by a highly resistant textile membrane makes the system perfectly suited for use in deep pools, as well as wastewater contaminated with oil, grease, acids and solvents.
Conventional rubber membranes are typically subject to natural aging and wear. The textile membrane, which is highly resistant to chemicals and heat, provides a reliable alternative.
The system delivers efficient oxygen supply and excellent mixing in the biological stage with minimal pressure drop.
It is low maintenance, quick and easy to install, and can also be produced as a lift-out version. This means that it can be lifted in and out even when the basin is full.

Aeration Systems for Modern Wastewater Treatment
Applications of the INVENT TEX-FLEX®-Aeration System
BOD or COD degradation
Highly efficient supply of oxygen to the microorganisms for BOD and nitrogen elimination.
The agitation and gassing system acts as a permanent aeration system for biological carbon degradation in aeration tanks. We can react flexibly to fluctuations in freight. The simultaneous circulation by the agitator ensures a homogeneous and deposit-free mixing even with low air supply in the activated sludge tank.
Aeration in very deep basins
Large water depths limit the area of application of many membrane ventilation systems due to high air temperatures.
Aeration in sludge applications
The iCBA system is the optimal, energy-efficient choice for stabilization operation or to avoid odors in thickened sludge.
Aeration in basins with problematic wastewater
When the use of conventional diaphragm materials is not possible due to the properties of the medium.
