It simulates the flow dynamics of larger, commercially available membrane elements such as industrial spiral wound membrane elements. By using a combination of Stainless Steel (SS) shims, feed spacers, and membranes, users can vary the operating conditions and fluid dynamics over broad ranges. Table 1 below outlines the operational parameters of the SEPA CF Cell. Table 1: SEPA CF Operating Parameters Parameter Effective Membrane Area Hold-Up Volume: Maximum Pressure: 316SS Cell Body Maximum Temperature: 316SS Cell Body O-rings: pH Range: Cross Flow Velocity Description 140 cm² (22-inch²) 70 ml (2.4 ounces) 69 bar (1000 psig) 177 °C (350 °F) Viton* (Other materials available) Membrane Dependent Variable (Table 2.1) Prior to operating or servicing this device, this manual must be read and understood. Keep it and associated information near the equipment. SEPA CF Cell Components Verify that the stirred cell was shipped complete, intact, and undamaged. The complete SEPA CF Cell includes: Stainless steel cell body, top and bottom Cell Top Cell Bottom 2 SEPA CF Cell Manual | Sterlitech Corporation Anodized aluminum cell holder with piston and high pressure gauge Concentrate control valve with high pressure gauge Tubing and hardware kit which includes: Feed Spacers 1 pack of 5 Permeate Carriers 3.0 meters (10 ft) concentrate tubing 1/4 diameter permeate tubing (91.4 cm (3 ft)) O-rings (2) The SEPA CF Cell also requires additional equipment to be operated, which are sold separately: Hydraulic hand pump to operate the cell holder Feed Pump Feed Tank Filtration membrane packs Assortments of shims and additional spacers Sterlitech Corporation | SEPA CF Cell Manual 3 SEPA CF Cell Assembly After verifying that all of the necessary components were shipped and present, you can begin the assembly of the crossflow cell. Cell Body Assembly The cell body consists of the cell top, permeate carrier, membrane filter, feed spacer, shims, orings, cell bottom, and concentrate control valve. Figure 1 below illustrates a typical assembly of the cell body. Figure 1. Cell Body Assembly 4 SEPA CF Cell Manual | Sterlitech Corporation To assemble the SEPA CF Cell Body: 1. Connect the concentrate flow control valve to the cell bottom by wrapping PTFE tape around the valve’s male NPT end and screwing it into the concentrate outlet port. Note: The cell bottom is the half of the cell body that has the four alignment pins. The cell top has the holes to accept the alignment pins. 2. Install the O-rings into the grooves on the cell bottom and wet them with a small amount of water or the fluid to be processed. Caution: Make sure that the O-rings lie flat in the grooves of the cell bottom. Leaking may occur if the O-rings do not lie flat in the grooves. The O-rings will be cut or crushed when the system is operating if the O-rings are not installed correctly. 3. Place a shim, if needed, in the cavity inside of the inner O-ring. Sterlitech Corporation | SEPA CF Cell Manual 5 4. Install the Feed Spacer into the central cavity, on top of the shim. The feed spacer must lie flat and be fully contained within the cavity. Note: The feed spacer and the permeate carrier look similar and are cut in the same size. The permeate carrier is thinner and has a tight weave while the feed spacer has large gridding. 5. Place a piece of pre-cut membrane over the feed spacer using the four guideposts to hold the membrane in position. The membrane should be installed with the shiny or active side down toward the feed spacer. Note: If you are cutting your own membranes, the membrane’s outer edge should fit between the inner and outer O-rings in the cell body to prevent leakage. 6 SEPA CF Cell Manual | Sterlitech Corporation 6. Wet the permeate carrier with water or the fluid to be processed and place it into the cavity in the cell top. The surface tension caused by wetting the carrier will keep it in place. 7. Complete the assembly of the cell body by placing the cell top onto the cell bottom. The alignment holes in the top should fit snugly over the alignment pins in the cell bottom. Sterlitech Corporation | SEPA CF Cell Manual 7 8. Once the cell body is assembled and the quick release connector is installed into the cell holder (See Cell Holder Assembly below), insert the cell body into the cell holder until it rests against the two stops in the cell holder. Caution: The cell body is very heavy: 14.5 kg (32 lbs). 8 SEPA CF Cell Manual | Sterlitech Corporation Cell Holder Assembly The cell holder is filled with Mobil DTE 20 Series Hydraulic Oil to operate the hydraulic piston. Before using the SEPA CF Cell for the first time, the brass quick release connector must be installed into the cell holder. To install the quick release connector into the cell holder: 1. Wrap PTFE tape clockwise around the threads of the brass fitting while the open end is facing you. 2. Move the cell holder into a vertical position with the shipping plug and/or pressure gauge facing upward. Caution: Attempting to install the brass quick release connector with the cell in the wrong position will cause the hydraulic fluid to spill. 3. Carefully remove the shipping plug in the hydraulic port on the cell holder. 4. Place the brass quick release connector into the hydraulic port. 5. Tighten the brass fitting with an open-ended wrench (1" wrench is suggested). Sterlitech Corporation | SEPA CF Cell Manual 9 SEPA CF Cell Connections Figure 2 shows the plumbing connections that need to be made for the operation of the SEPA CF Cell, the configuration can change slightly depending on the objectives of the user. In general, the connections to be made are: Hydraulic pressure source to the cell holder Feed vessel to the inlet pump Pump outlet to the feed inlet of the cell body Concentrate flow control valve to the feed vessel Permeate outlet to the permeate collection vessel Figure 2. Example SEPA CF Flow Diagram 10 SEPA CF Cell Manual | Sterlitech Corporation To connect the hydraulic pressure source to the cell holder: 1. Push the quick release fitting of the hose of the hydraulic pressure source against the quick release fitting installed into the cell holder. The outer collar of the female fitting will extend about 3.2 mm (⅛"). 2. Rotate the collar on the female fitting ¼ turn so the notch and the groove do not line up. To disconnect the hydraulic pressure source to the cell holder: 1. Release all hydraulic pressure in the system. Warning: Do not disconnect the hydraulic pressure source from the cell holder while the system is pressurized. 2. Turn the collar on the female fitting until the notch and the groove line and push the collar to separate the fittings. To connect the feed vessel to the feed pump and SEPA CF Cell: 1. Attach a fitting for the ⅜" nylon tubing provided with the SEPA CF Cell to the feed pump. 2. Once the fitting is in place, insert the tubing firmly into the open end. The tubing should seat in the fitting and should be easily removable. 3. Connect a length of ⅜" nylon tubing or high pressure hose from the outlet of the pump to the feed inlet of the cell body. Warning: Nylon tubing is rated for operations less than 250 psig (17.2 bar). Highpressure tubing, such as the PTFE-lined SEPA hose, must be used for the connection between the pump outlet and the feed inlet if the SEPA CF is being operated at higher pressures. To connect the concentrate control valve to the SEPA CF Cell: 1. Connect the concentrate control valve by screwing the ⅜" male pipe thread into the female threads of the SEPA CF outlet and tighten. 2. Connect a length of ⅜" nylon tubing to the tube fitting on the concentrate control valve. 3. Insert the free end of the tubing into the feed vessel or a separate vessel if you wish to collect the concentrate separately. To connect the permeate outlet to the permeate collection vessel: 1. Connect a length of ¼" nylon tubing to the permeate outlet using the polypropylene fitting provided. 2. Insert the free end of the tubing into the permeate collection vessel. Ensure that all connections are snug. Sterlitech Corporation | SEPA CF Cell Manual 11 Operation of the SEPA CF Cell Once the SEPA CF Cell has been assembled and connected to a feed system, it can be used in variety of applications that includes reverse osmosis, ultrafiltration, nanofiltration, and microfiltration. To operate the SEPA CF Cell: 1. Set the feed pressure less than or equal to the piston pressure on the cell holder/cell body and turn the feed flow pump on. Note: A good starting point may be to set the system at 1.7 bar (25 psig) pressure for ultrafiltration, 17.2 bar (250 psig) for reverse osmosis, and 2–3 Lpm (0.5–0.8 gpm) concentrate flow. If this does not produce the desired results then the parameters can easily be adjusted and different membranes can be used. 2. Verify the feed pressure by comparing the reading on the piston cell holder pressure gauge to the reading on the concentrate pressure gauge. 3. Adjust the concentrate flow control valve to obtain the desired pressure and flow. Experimentation enables you to determine the optimum settings for pressure, flow rate, and shim/spacer combination to use on the chosen membrane and the fluid being processed. To replace a membrane filter: 1. Turn the feed flow pump OFF. 2. Turn the knob (counterclockwise) on the pressure relief valve on the hydraulic pump to release the hydraulic pressure in the system. 3. Slide the cell body out of the cell holder. 4. Separate the cell body top from the cell bottom. 5. Remove the membrane. 6. Remove the permeate carrier, if necessary. Note: Typically the feed spacer and permeate carrier do not have to be removed. 7. Install the new membrane (and, if necessary, a new permeate carrier). 8. Reassemble the cell top and bottom. 9. Return the cell body to the cell holder. 10. Reactivate the piston mechanism. 11. Turn the feed flow pump on. 12 SEPA CF Cell Manual | Sterlitech Corporation Supplementary Operating Information Membrane Performance Results 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 differential across the membrane and possible damage. Hollow fiber membranes, tubular membranes, and membranes with tubular spacers may be operated at higher velocities, but this may not contribute to a more effective operation. Membrane Cell Performance Other parameters such as viscosity, pressure, and suspended solids may also affect performance/operation. Experimentation with the SEPA CF Cell 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 2, #4), which is not supplied with the system. Temperature Limits The membranes, feed spacer, permeate, O-rings, and cell body materials construction dictates maximum temperatures. Table 2: Upper Temperature Limits Component Maximum Temperature 316 SS Cell: 177 °C (350 °F) Membrane Element: Variable Feed Spacer: 82 °C (180 °F) Permeate Carrier: 82 °C (180 °F) O-rings Viton 200° C (400° F) EPDM 150° C (300° F) Autoclaving the 316SS cell body is acceptable, recognizing the temperature limitation of 82°C (180°F) on the membrane, feed spacer, and permeate carrier. The cell holder should never need to be autoclaved because it does not come into contact with the process fluid. Membrane Cleaning The SEPA CF Cell 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. This can be done with CIP. Clean-InPlace 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 recirculate the cleaning solutions.

Sterlitech Corporation | SEPA CF Cell Manual 15 Appendix 1: Swagelok 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 preswaged 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. 16 SEPA CF Cell Manual | Sterlitech Corporation Appendix 2: Cutting Custom Membrane Filters Sterlitech offers a wide variety of RO/NF/UF/MF membranes that are available pre-cut for use with the SEPA CF Cell. However, if you need to cut your own membrane, you will need the following items: The provided SEPA CF template The membrane sheet to be cut A pair of sharp scissors A pair of latex gloves To cut membrane filters for the SEPA CF Cell: 1. Take the provided template and place the membrane sheet against it. Be sure to have the latex gloves on to avoid contaminating the membrane surface. 2. Cut along the edge of the template with the scissors. Hold the scissors at an angle towards the center of the template to avoid under-trimming. Once finished, the membrane should sit perfectly flat on supports without any bending and extend outside of the inner O-ring to avoid leakage. Note: Sterlitech also offers steel ruled dies (P/N SEPA Die) that are designed to cut the membrane to the correct size and shape. Sterlitech Corporation | SEPA CF Cell Manual 17 Appendix 3: Preconditioning Membranes for Use Once the membrane is cut and fitted, it needs to be pre-conditioned. Membranes that are not pre-conditioned may have different behaviors and fluxes, which will give inconsistent results. Figure 4 below illustrates the instability of the flux, particularly at the start of the trial, through unconditioned membranes. Figure 4: Example of Performance Variance Using Unconditioned Membranes To precondition the membrane: 1. Load the membrane into the SEPA CF Cell 2. Fill the feed tank with deionized water and pressurize the cell. The temperature of the water and the pressure used should be exactly the same as the temperature and pressure that will be used in the actual trials. 3. Run the deionized water through the cell for two hours. After about 30 minutes, flux through the membrane will stabilize after a sharp fall. Over the next 90 minutes, the flux should be steady, indicating that the membrane is conditioned (see Figure 5 below). Figure 5: Stabilizing Flux with Preconditioning 4. Release pressure, discard the deionized water and fill the cell with your sample. 18 SEPA CF Cell Manual | Sterlitech Corporation Appendix 4: Temperature Correction Factor for Filmtec™ Membranes Table 4: Temperature Correction Factor for Filmtec™ Membranes Temperature °C Temperature Correction Factor Temperature °C Temperature Correction Factor Temperature °C 10.0 1.711 14.0 1.475 10.1 1.705 14.1 1.469 10.2 1.698 14.2 1.464 10.3 1.692 14.3 1.459 10.4 1.686 14.4 1.453 10.5 1.679 14.5 1.448 10.6 1.673 14.6 1.443 10.7 1.667 14.7 1.437 10.8 1.660 14.8 1.432 10.9 1.654 14.9 1.427 11.0 1.648 15.0 1.422 11.1 1.642 15.1 1.417 11.2 1.636 15.2 1.411 11.3 1.630 15.3 1.406 11.4 1.624 15.4 1.401 11.5 1.618 15.5 1.396 11.6 1.611 15.6 1.391 11.7 1.605 15.7 1.386 11.8 1.600 15.8 1.381 11.9 1.594 15.9 1.376 12.0 1.588 16.0 1.371 12.1 1.582 16.1 1.366 12.2 1.576 16.2 1.361 12.3 1.570 16.3 1.356 12.4 1.564 16.4 1.351 12.5 1.558 16.5 1.347 12.6 1.553 16.6 1.342 12.7 1.547 16.7 1.337 12.8 1.541 16.8 1.332 12.9 1.536 16.9 1.327 13.0 1.530 17.0 1.323 13.1 1.524 17.1 1.318 13.2 1.519 17.2 1.313 13.3 1.513 17.3 1.308 13.4 1.508 17.4 1.304 13.5 1.502 17.5 1.299 13.6 1.496 17.6 1.294 13.7 1.491 17.7 1.290 13.8 1.486 17.8 1.285 13.9 1.480 17.9 1.281 Source: Dow Technical Manual, Form No. 609-02129-804 18.0 18.1 18.2 18.3 18.4 18.5 18.6 18.7 18.8 18.9 19.0 19.1 19.2 19.3 19.4 19.5 19.6 19.7 19.8 19.9 20.0 20.1 20.2 20.3 20.4 20.5 20.6 20.7 20.8 20.9 21.0 21.1 21.2 21.3 21.4 21.5 21.6 21.7 21.8 21.9 Temperature Correction Factor Temperature °C Temperature Correction Factor Temperature °C Temperature Correction Factor 1.276 1.272 1.267 1.262 1.258 1.254 1.249 1.245 1.240 1.236 1.232 1.227 1.223 1.219 1.214 1.210 1.206 1.201 1.197 1.193 1.189 1.185 1.180 1.176 1.172 1.168 1.164 1.160 1.156 1.152 1.148 1.144 1.140 1.136 1.132 1.128 1.124 1.120 1.116 1.112 22.0 22.1 22.2 22.3 22.4 22.5 22.6 22.7 22.8 22.9 23.0 23.1 23.2 23.3 23.4 23.5 23.6 23.7 23.8 23.9 24.0 24.1 24.2 24.3 24.4 24.5 24.6 24.7 24.8 24.9 25.0 25.1 25.2 25.3 25.4 25.5 25.6 25.7 25.8 25.9 1.109 1.105 1.101 1.097 1.093 1.090 1.086 1.082 1.078 1.075 1.071 1.067 1.064 1.060 1.056 1.053 1.049 1.045 1.042 1.038 1.035 1.031 1.028 1.024 1.021 1.017 1.014 1.010 1.007 1.003 1.000 0.997 0.994 0.991 0.988 0.985 0.982 0.979 0.977 0.974 26.0 26.1 26.2 26.3 26.4 26.5 26.6 26.7 26.8 26.9 27.0 27.1 27.2 27.3 27.4 27.5 27.6 27.7 27.8 27.9 28.0 28.1 28.2 28.3 28.4 28.5 28.6 28.7 28.8 28.9 29.0 29.1 29.2 29.3 29.4 29.5 29.6 29.7 29.8 29.9 0.971 0.968 0.965 0.962 0.959 0.957 0.954 0.951 0.948 0.945 0.943 0.940 0.937 0.934 0.932 0.929 0.926 0.924 0.921 0.918 0.915 0.913 0.910 0.908 0.905 0.902 0.900 0.897 0.894 0.892 0.889 0.887 0.884 0.882 0.879 0.877 0.874 0.871 0.869 0.866 ™® Trademark of The Dow Chemical Company (“Dow”) or an affiliated company of Dow Sterlitech Corporation | SEPA CF Cell Manual 19 Appendix 5: Membrane Test Log Membrane Test Log: Operational Parameters and Performance System Stage # Choose units Date Time Date Time 20 Operator UNITS: FEED SDI pH Housing # TDS CONCENTRATION FLOW PRESSURE Temp Feed Perm Conc Conc Perm Feed Conc Perm ⁰F / ⁰C ppm or mg/L ppm or mg/L ppm or mg/L gpm gpm psig psig psig SEPA CF Cell Manual | Sterlitech Corporation Comments Appendix 6: SEPA CF Cell Applications The following studies utilized the SEPA CF Cell in their method and are listed here to illustrate the potential applications for the SEPA CF.
