Flat as a sheet.
Strong as a shield.
Two membranes, one sheet
The Blue Foot membrane is a thin envelope of two polymeric ultrafiltration membranes, 4 mm thick, with an integrated permeate channel (IPC) in the middle. What makes this IPC™ technique truly unique, is that the two layers are physically integrated into the 3D spacer fabric. As a result, the membrane is virtually unbreakable.
Our membranes are made of polyvinylidene difluoride (PVDF), a highly resistant polymer. The spacer fabric is a robust, woven polyester textile with an open structure. The mechanical anchoring results in unprecedented pressure resistance in both directions. This enables the unique, unparalleled and evenly distributed high pressure backwash.
Does your installation need an unbreakable membrane?
Multiple sheets, one module
The membrane sheets are combined into a single module, the smallest unit in any installation. One Blue Foot module consists of a number of membrane sheets side by side. The spacing of the individual sheets is critical, ensuring an equal flow along all membrane sheets. Equal spacing between the sheets ensures a uniform flow along all membrane sheets.
Multiple modules, one stack
For an optimal use of space, up to three modules can be stacked. The stacks are easy to assemble, install and maintain. They are fully standardised and allow for a modular build-up of any installation. Since all modules in a stack use the same air diffuser box, both aeration and footprint are minimised.
Multiple stacks, many possibilities
To optimise efficiency, maximise uptime and fulfill all your water treatment demands, stacks can be easily grouped to adapt to every situation
Where it is used
New plant realisation
The Blue Foot compact design leads to significantly lower investment costs.
Existing plant upgrade
Convert a conventional wastewater treatment plant to a reuse variant by means of a compact, bolt-on membrane separation section.
Existing plant retrofit
When membrane replacement is required, achieve the lowest OPEX and highest reliability with Blue Foot.
