Aquaflex
Aquaflex modules are based on hydrophilic hollow-fiber ultrafiltration membranes, composed of a PES/PVP blend. The membranes, which are operated in a dead-end mode, have high mechanical and chemical strength, making them suitable for a wide range of applications. The pressurized membrane modules with inside-out configuration are the industry’s choice for the removal of bacteria, viruses, suspended solids, and colloids.

Functional Description
X-flow aquaflex membrane modules
The core of the Aquaflex membrane technology is the single-fiber, inside-out filtration process that delivers a robust solution. The modules are operated vertically and can be configured in three different ways:- In the X-line rack
- With standard end caps
- In the vertical high pressure setting

Fields of application
Potable water production
The Aquaflex membrane modules provide superior separation performance and effective rejection of viruses and chlorine-resistant organisms such as Cryptosporidium and Giardia.
Process water production
The membrane modules offer an effective barrier to suspended solids and silt. The permeate can be used directly or, if salinity and dissolved solids are not within the required limits, the permeate can be fed to a downstream RO system.

Effluent polishing
The Aquaflex membrane modules are a reliable solution to meeting the highest standards for turbidity and microbiology. The polished effluent is ready for high- grade and unrestricted reuse applications.
Swimming pools
Due to their high chlorine stability, the Aquaflex elements are highly suitable to treat chlorinated water from swimming pools. Apart from providing a barrier to suspended solids, the membrane modules also effectively remove microbial particles, so that pool water chlorination can be dramatically reduced.
