Septic & decentralized MBR · Swing flat-sheet
Septic MBR without anyone going into the tank.
Having trouble with spiral-wound MBR in septic tanks? The Zyramic Swing septic cassette is a flat-sheet alternative: a 304 stainless steel frame holding 2 membrane cartridges that drops into the tank through a manway. The cassette and cartridges lift straight out from above, so they can be checked, cleaned or replaced from the surface.


Why flat-sheet for septic
Simple to install, simple to service.
Lift-out service
Each Swing cartridge comes straight up and out from above. Service is done from the surface, with no tank entry.
MF membranes
Microfiltration flat sheets suited to onsite biological treatment.
Air scour
Continuous air scour between the sheets keeps the membrane surface clean in day-to-day running.
Reuse-grade effluent
The membrane is the barrier: clear, low-solids effluent suitable for reuse and sensitive discharge sites.
Compact
157 ft² of membrane in a cassette 26.0 x 20.6 x 47.2 in, sized to drop into a septic tank through a manway.
Made by Zyramic
Zyramic manufactures Swing cartridges and modules, with US assembly and service in Poughkeepsie, New York.

Septic MBR FAQ
Why use flat-sheet cartridges instead of spiral-wound MBR in a septic tank?
Swing cartridges lift straight out from above for inspection, cleaning or replacement. Air scour keeps the sheets clean in the tank, so service is simpler and nobody needs to enter the tank.
Are Swing membranes MF or UF?
For septic and decentralized MBR we supply Swing with microfiltration (MF) membranes, which suit onsite biological treatment.
Who is this for?
