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 membraneelements. 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
1. If you are using a female 1812 element, Insert the adaptors into the element (Figure 2,
#1,2)
2. Remove clamp (Figure 3, #1) and open up the Bottom End Cap (keep the Top End Cap
intact, Figure 4, #1).
3. Insert element into the housing in the correct orientation, i.e. inserted from the side of
the housing where the bottom end cap is, so that O-rings on the permeate line adaptor fits
snugly in the Top End Cap.
4. Push Bottom End Cap until element is fully inserted into the housing. This may take a bit
oorce.
Note: Applying Glycerin to the two O-rings installed on the permeate tube is
recommended to ensure that there will be no leaks.
5. Put high-pressure clamp back on the Bottom End Cap and tighten.
WARNING: Do not exceed 600 psi (41 bar) in the 1812 Housing.
To remove the 1812 Element from the housing:
1. Remove the clamp (Figure 4, #1) and open up Top End Cap
2. Remove the element by pulling the element through the Top End Cap (Figure 4, #1).
3. Separate the element from the Top End Cap by pulling it out.
4. If you are not using this element any more, Remove the adaptors and save them for next
element.

Figure 5 shows typical plumbing connections that need to be made for the operation of
the 1812 Housing, the configuration can change slightly depending on the objectives of the
user. In general, the connections to be made are:
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 5 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.

5. Operation of the 1812 Housing Assembly
6. Supplementary Operating Information
6.1. Membrane Performance Results
6.2 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 pumpon.
3. Set the feed pressure to be less than 600 psig by gradually closing the concentrate
control valve (Figure 5,8).
4. Verify the feed pressure reading on the concentrate pressure gauge (sold separately)
(Figure 5, 8).
5. Adjust the bypass valve (Figure 5, 4) and concentrate control valve (Figure 5, 8) to
obtain the desired pressure and flow. 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 4, 4),
which is not supplied with the housing.

6.3. Temperature Limits
6.4. 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.
