What we do in Poughkeepsie
Our shop runs membrane welding and cutting equipment and assembles modules on site, using domestic and imported components. We supply Swing MBR cartridges and modules, Palisade plate modules, Scrub UF units, and replacement flat-sheet membranes sized to fit existing cassettes, with strong wide membrane welds designed to resist delamination. Visit the shop page for photos and capabilities.
Custom sizes for your application
Customization is our specialty. Because we cut and weld membranes, build frames and assemble modules in Poughkeepsie, NY, we can tailor many dimensions to your project in many cases. Tell us your tank dimensions and we will propose a fit.
| Item | What we can tailor | Why it helps |
|---|---|---|
| Membrane sheet size | Sheets cut to suit the cartridge or plate | Small sheets flex less for less wear and tear, joined with strong wide membrane welds |
| Cartridge size | Cartridge dimensions and membrane area | Match the area you need without oversizing |
| Module / frame size and height | Frame width, depth, height and number of decks | Fit water depth and lifting clearance |
| Footprint for existing tanks | Layouts sized to existing basins and retrofits | Often avoids new civil work |
| Quick cartridge replacement | Cartridge access designed into the module | Replace a cartridge quickly, in minutes, without pulling the whole module |
Funded projects and domestic content
Projects with federal or state funding may carry domestic-content requirements. Tell us your domestic-content requirements and we'll review what we can document for your configuration. Local assembly can also help with communication, engineering support and custom replacement sizes in small quantities.
Working with engineers and owners
We provide datasheets, drawings and a guide specification on the resources page, support design reviews, and quote modules, replacements and rentals. We sell membranes, not complete plants, and work alongside your engineer and contractor.
Worked sizing example
Take a grant-funded town plant at 660,430 gpd (2,500 m³/day):
| Item | US | Metric | Note |
|---|---|---|---|
| Average flow | 660,430 gpd | 2,500 m³/day | about 459 gpm (104,167 L/h) |
| Design flux (gross) | 11.8 gfd | 20 LMH | Zyramic design guidance |
| Derate for relaxation and cleaning | ~20% | ~20% | |
| Net flux | ~9.4 gfd | ~16 LMH | |
| Membrane area needed | ~70,077 ft² | ~6,510 m² | average flow ÷ net flux |
| Swing-8 cartridges | ~521 | ~521 | 135 ft² (12.5 m²) each |
| Peak factor | ~2.5 | ~2.5 | |
| Peak flow | ~1,651,075 gpd | ~6,250 m³/day | extra area, short-term higher flux, or equalization |
This is an illustration only; a real design also checks temperature, MLSS, redundancy and the cleaning schedule.
Tips for a smooth project
- Compare modules on lifecycle, not area alone
- Plan how replacement parts will be sourced later
- Allow room for handling and inspection
- Check cassette dimensions before ordering replacements
Next step
A good way to see which design choices matter most for your plant is to look at your own maintenance history. Tell us what has needed attention in the past, and we will explain which of our options fits it best.
Sizing considerations
To give a useful recommendation we usually need:
- Funding source and any domestic-content requirements
- Flows and effluent limits
- Retrofit or new construction
- Schedule
- Specification section, if any

Why engineers look at Zyramic flat-sheet modules
| Item | Details |
|---|---|
| Smaller sheets, less wear and tear | each sheet flexes less in service, and a damaged unit affects less area. |
| Strong wide membrane welds | designed to resist delamination over the membrane's life. |
| Thick, robust membrane | about 250 microns including support. |
| Assembled in Poughkeepsie, NY | of domestic and imported components. In our Poughkeepsie shop we cut and weld membrane sheets to plates, build module frames and assemble complete modules. For funded projects, tell us your domestic-content requirements and we'll review what we can document. |
| Buy, rent or replace | new modules, rentals and pilots for US projects, and replacement membranes that fit many existing cassettes. |
Performance and life depend on pretreatment, design flux and operation; flux figures are Zyramic design guidance, sized to each project.
Frequently asked questions
