Summary
Product identification
Veolia's Stainless Steel Membrane Housings are designed for 4-inch side entry membrane elements and suitable for RO/NF/UF machine assembly. These housings feature a mechanical coupling closure and a 4-port design to simplify manifolding.
Features and Benefits
- Mechanical Coupling Closure: Single-piece end cap secured with a mechanical coupling and Victaulic closure system, sealing with a single gasket. This design eliminates the need for grooves or holes, prevents O-ring tearing, and allows quick membrane element changes without special tools.
- 4-Port Design: Uses four side ports instead of high-pressure interconnecting manifolding, reducing fabrication time and assembly costs. Interstage port plugs direct flow, enabling superior performance in various array schemes, including two-pass systems.
- Material Advantages (Stainless Steel):
- No seals involved in side port connections.
- Does not warp or weep, unlike fiberglass.
- Unaffected by UV rays or sunlight.
- A preferred and universally accepted material for water systems.
- Can withstand high temperatures, up to 200°F (93°C) of supporting process piping.
- Lighter and easier to handle during assembly than PVC and FRP housings with equivalent pressure ratings.
Options Available
- Grade: 316L Stainless Steel
- Side Ports:
- 3/4", 1-1/4", and 1-1/2"-inch port sizes.
- Multi-port (2 & 4 port standard).
- Tri-clamp (standard is Victaulic).
- Finishes:
- Original steel mill finish (standard).
- Painted with acrylic polyurethane paint (most colors, e.g., bright aluminum).
- Electro-polished for a glossy, shiny, metallic look.
- Mechanical polished (180 grit), inside diameter and/or outside diameter.
- Design Options:
- Low pressure made with Noryl end caps (500 psi).
- High pressure made with 316 stainless steel end caps (1,000 psi).
- Sanitary made with polished 316 stainless steel end caps.

- Add 2-inches (51 mm) to dimension A for the overall length including the end caps.
- S1 and S2 dimensions are recommended housing support locations from each end. If no S2 dimension is listed, only two end supports are required.
- The two-port configuration is standard; a four-port configuration is also available.
