Zyramic Palisade flat sheet membrane with targeted scouring (patent pending)
Zyramic Palisade is the submerged flat-sheet membrane bioreactor (MBR) cassette. Targeted scouring uses a detachable modular scour manifold on the bottom of the plate. Check valves keep sludge and mixed liquor out of the air path. Dedicated scour, 24/7, every plate. Patent pending.
The cassette
Built to drop in
304 stainless frame (316 optional). Dual headers. Targeted scouring on the bottom of each plate. Municipal and industrial wastewater treatment. Sewage treatment. Built to run submerged in mixed liquor.
Installed
In the tank
Municipal membrane tank. The cassette runs submerged. Rendering.
Install options
Quoted with the module
Lifting attachments, guide rails, and adjustable feet are quoted options. The cassette runs submerged. Yard piping meets the headers.
Why it stays clean
Every channel. Short plate. Real spacing.
Targeted scouring uses a detachable modular scour manifold. It attaches to the bottom of the plate. Check valves keep sludge and mixed liquor out of the air path. It stays put in the tank. You change it on the bench.
Dedicated scour, 24/7, every plate. The cassette wants its own scour air, running — not plant air that comes and goes. That is how you protect the investment.
Uniform water velocity between each plate. Same velocity, same scour on every plate.
Plates have room to scour. They are 41.2 in (1,047 mm), so the top of the plate stays clean. Channels stay open. You stay out of the tank.
The polypropylene support plate holds PES from a global life-sciences membrane manufacturer. That sheet has been in the market for years. A major German producer already runs it. The plate is a lightened PP plate for handling. PP is a lighter polymer of domestic and foreign components, from American natural gas. Manufactured in the United States of domestic and foreign components; BABA (Build America, Buy America) is claimed at the module — see Company. No PFAS.

Cleaning in Place
CIP
CIP restores permeability after scour, relaxation, and flux discipline. This is the clean for the polymer flat-sheet PES cassette.
Physical measures first: scour at every module, the relax cycle, flux at the project design, screening, and MLSS. Chemistry comes with a Zyramic-written recipe for that job — agent, concentration, time, and temperature. Recipes are issued in the project submittal or a later O&M revision. This page does not publish a strength or a soak time.
When a recipe is issued, the work is in-tank. Modules stay submerged. The restraint stays on. Follow the recipe on scour during the soak, and record agent, concentration, temperature, duration, and TMP before and after.
CIP is the clean for this sheet. The PES cassette is not backwashed.

Independent CFD
An independent study compared targeted scouring with a conventional bottom-plenum air scour on identical plate geometry. Near-field liquid shear at the channel base was about four times higher. That is the base, on identical plates. Hydrodynamics. Independent FEA covers the module in operation and in lift-out, worst case included: wetted, double-deck. Figures: How it works.
Questions people ask
Straight answers
What is the Zyramic Palisade flat sheet membrane with targeted scouring (patent pending)?
Zyramic Palisade is a submerged flat-sheet membrane bioreactor (MBR) module with targeted scouring. A detachable modular scour manifold attaches to the bottom of the plate. Check valves keep sludge and mixed liquor out of the air path. Dedicated scour, 24/7, every plate. The polypropylene support plate holds PES from a global life-sciences membrane manufacturer.
Is Zyramic Palisade a BABA MBR module?
Yes. Zyramic Palisade is manufactured in Poughkeepsie from US and imported parts. BABA (Build America, Buy America) applies at the module, not a treatment system — see Company.
What membrane is on the polymer plate?
PES from a global life-sciences membrane manufacturer. The sheet has been in the market for years. A major German producer already runs it. The support plate holds the sheet so edges do not fray or delaminate the way a thin-film sheet can.
How big is the commercial module?
130 plates single deck, 260 plates double deck. About 1.05 m² per plate, both faces. Panel height is 41.2 in so the top stays clean. Scour intensity is 10 L/min per m² of membrane.
Does independent work back the design?
Independent CFD compared targeted scouring with a conventional bottom plenum on identical plates. Near-field liquid shear at the channel base was about four times higher. That is hydrodynamics, not plant data. Independent FEA covers the module in operation and in lift-out, worst case included: wetted, double-deck.
Is this for sewage treatment and water reuse?
Yes. Zyramic Palisade is a submerged flat-sheet MBR module for municipal sewage treatment, industrial wastewater treatment, and wastewater filtration. Permeate is often the feed to a reuse or reverse-osmosis step. CIP restores permeability. The PES cassette is not backwashed.
