The 1812 Spiral Wound Membrane Housing is a bench-scale crossflow filtration system that is designed
to evaluate 1812 spiral wound membrane elements in a variety of applications. It simulates the flow
dynamics of commercially available spiral wound membrane elements. Users can vary the operating
conditions and fluid dynamics over broad ranges.
Table 1 below outlines the features and technical specifications of the 1812 Spiral Wound Membrane
Housing (hereafter referred to as 1812 Housing).
Prior to operating or servicing this device, this manual must be read and understood.

After verifying that all of the necessary components were shipped and present, you can begin
the assembly of the system.
To assemble the 1812 Element into the housing:
To remove the 1812 Element from the housing:
1. Close the longer end of the permeate tube of the membrane module (the end without
the PTFE seal) using the compression connection (Figure 2, #1). Appendix 1 shows how to
install Swagelok Tube Fittings
2. Connect the hollow compression connection to the shorter end of the tube (the end with
the PTFE seal) (Figure 2, #2).
3. Connect the hollow end cap to the hollow compression connection (Figure 3#1)
4. Insert the membrane module in the housing starting from the close end of the permeate
tube (Figure 4, #1,2)
Note: make sure the gasket (Figure 1, #3) is in place before connecting the top end cap to
the tube
5. Use the tri clamp fitting to secure the hollow end cap (Figure 4, #3)
6. Place the solid end cap on to the other side of the element and secure it using the tri
clamp fitting. (Figure 5, #1,2)
7. Connect the feed inlet, retentate outlet and permeate outlet houses using the clamps
NOTE: Feed inlet should be connected to the side of the housing where top end
cap is connected and the retentate outlet tubing should be connected to the side
where the end cap is connected
The 1812 Housing is now assembled and ready to be connected to a feed pump for
operation.
WARNING: Do not exceed 870 psi (60 bar) in the 1812 Housing.
1. Remove the clamp and open up hollow end cap.
2. Remove the element by pulling the element through the hollow end cap.
3. Separate the element from the hollow end cap.

Figure 6 shows the typical plumbing connections that are needed for the operation of the
1812 Housing; the configuration can change slightly depending on the objectives ofthe user.
In general, the connections needed are as follows:
1. Feed vessel to the pump inlet
2. Pump outlet to the feed inlet of the 1812 housing
3. Concentrate outlet of the 1812 housing to the feed vessel
4. Permeate collection tube to the permeate collectionvessel
Figure 6 also lists the additional components that are necessary to operate the 1812
Housing. These components are sold separately and can be found in the Membrane/ Process
Development section of the Sterlitech website (http://www.sterlitech.com/membrane-
process-development.html). The final assembly of the system will vary with the feed vessels,
pumps, and tubing used.

4. Operation of the 1812 Housing Assembly
5. Supplementary Operating Information
5.1. Membrane Performance Results
5.2 Membrane Performance
Once the 1812 Housing has been assembled and connected to a feed pump, it can be used
in reverse osmosis, ultrafiltration, nanofiltration, and microfiltration separation processes
for applications in a variety of industries, including food and beverage, pharmaceutical, or
industrial.
To operate the 1812 Housing Assembly:
1. Open all of the valves in the system to relieve any pressure build-up before turning on
the feedpump.
2. Turn the feed pump on.
3. Set the feed pressure to be less than 600 psig by gradually closing the concentrate
control valve (Figure 6,8) (sold separately).
4. Verify the feed pressure reading on the concentrate pressure gauge (sold separately)
(Figure 6, 8).
5. Adjust the bypass valve (Figure 6, 4) and concentrate control valve (Figure 6, 8) to
obtain the desired pressure and ow. Experimentation enables you to determine the
optimum settings for pressure, and flow rate to use on the chosen membrane and the fluid
being processed.
6. Once the experiment is complete, shut down the system by turning the feed pump o and
opening all of the valves to relieve any pressure buildup.
Spiral wound membranes containing mesh spacers are usually operated with a fluid velocity
across the membrane surface of 0.1–0.5 m/sec (0.3–1.6 ft/sec). Higher velocities in membranes
may lead to excessive pressure dierential across the membrane and possible damage.
Other parameters such as viscosity, pressure, and suspended solids may also aect
performance/operation. Experimentation with the 1812 Housing can help predict the best
operating parameters. If your pump is delivering too much flow, a portion of the flow can
be diverted back to the feed container before entering the feed inlet of the cell body. This
requires installation of an optional bypass valve and fitting on the pump outlet (Figure 6, 4),
which is not supplied with the housing.

5.3. Temperature Limits
5.4. Membrane Cleaning
The membranes, feed spacer, permeate, O-rings, and cell body materials construction dictates
maximum operating temperatures.
The 1812 housing can be cleaned easily after the membrane is removed. However, you may
wish to simulate the actual cleaning conditions of Cleaning-In-Place (CIP) in larger systems
with spiral-wound or tubular membranes. CIP chemically cleans without removing the
membrane to mechanically scrub the unit.
During CIP, cleaning solutions are re-circulated and, in some cases, allowed to sit for a period
of time within the cell body. In some cases, the feed pump can be used to re- circulate the
cleaning solutions.

Appendix 1: Compression Connections
To install Swagelok Tube Fittings:
1. Insert the tubing into the Swagelok tube fitting. Make sure that the tubing rests firmly on
the shoulder of the fitting and that the nut is finger-tight.
2. Scribe the nut at the 6 o’clock position. By scribing the nut at the 6 o’clock position as it
appears to you, there will be no doubt as to the starting position.

3. Hold the fitting body steady with a backup wrench and tighten the nut 1¼ turns. Watch
the scribe mark, make one complete revolution and continue to the 9 o’clock position.
When the nut is tightened to the 9 o’clock, you can easily see the fitting has been
tightened properly.
Swagelok connections can be disconnected and retightened many times.
To retighten the Swagelok connection:
1. Start with the disconnected fitting.

2. Insert tubing with pre-swaged ferrules into fitting body until front ferrule seats.
3. Tighten the nut by hand. Rotate nut to the original position with a wrench. An increase
in resistance will be encountered at the original position. Then tighten slightly with the
wrench.
