  • Page 25 2. Check the quantities of UF modules and rack parts with the list provided. Inspect 　the UF module and rack components for any defects or damages. Contact Toray 　officials if you find any mismatches in the number of the module and parts, defects, 　or damages.
  • Page 26 Toray UF 6. Set the assembled Base Channel at the planned position, and mark drill hole positions for Anchor Bolts. To check the installation position more precisely, place a bottom header with a Flange temporarily on the Base Channel, and make sure it can be connected to the Flange of the feed pipe to which it will be connected.
  • Page 27 Toray UF 11. Set a bucket to receive the preservative solution and remove a plugging plate of the upper side nozzle. Be cautious of preservative solution which comes out when the plate is opened. Turn the module nozzle down and remove the preservative solution.
  • Page 28 Toray UF 12. Place Header-1#1 [11] and Header-1#2 [12] to each end of the module. Air injection is attached to the Header-1#2, but not to the top header. Make sure that the O-ring [9] between the module and the header fits correctly.
  • Page 29 Toray UF 13. Cover with a pair of the V-band half-shells for Module [8] which is described in step 11 so that the protrusion and the circle mark are visible through the V-band window and tighten the V-band. Make sure the bolts are securely fastened to prevent leaks.
  • Page 30 Toray UF 15.To connect to the pipes, attach Flange Conversions to the four headers (the top and bottom headers) of two modules of the rack. Using the Housing Joint DN150 with gasket [15], attach a Flange Conversion [16] to each header of one module (Module #1).
  • Page 31 Toray UF 18. Position Module #1 so that three edges of the Header-1#2 (Bottom Header) are aligned with those of the Base Channel (See the yellow line in the right figure). Place a spirit level tool along the module and make sure the module is installed in vertical direction (see the step 21).
  • Page 32 Toray UF 20. Using the Housing Joint 65A [10] described in the step 11, attach the Long Elbow [18] to the upper side nozzle of the module so that the long pipe of the Long Elbow points vertically upwards. 21. Place a spirit level tool along the long pipe of the Long Elbow and make sure the Long Elbow is installed in vertical direction at least at two sides.
  • Page 33 Toray UF 23. Attach the gaskets for the top and bottom headers in the Housing Joints DN150 [15] to the opening of each header of Module #1. 24. Repeat the steps 17 to 23 to install Module #2 on the Base Channel opposite to Module #1 with its side nozzles facing Module #1 and attach the Long Elbow.
  • Page 34 Toray UF 27.Repeat the steps 17 to 26 continuously to install the module next to the installed module that starts from Module #2, to attach the Long Elbow, and to connect the adjacent Headers. On the way to these steps, install Central Fixtures [20].
  • Page 35 Toray UF 30. The mounting positions of the Flat Bars [21], the Bolts [22], and the Manifold Base [23] are shown in the drawing below. The Flat Bars and the Manifold Base should be fixed in the following order: 1) Placing and fastening the Flat Bars at the outer sides (1-1, 1-2, 4-1 and 4-2).
  • Page 36 Toray UF 32. Assemble the manifold for the Flange Conversion side. Wet the O-ring with clean water. Using the O-rings [24] and the V-bands for Manifold [25], attach the Flange Conversion [26] to the Manifold [27]. Make sure the bolts are securely fastened to prevent leaks.
  • Page 37 Toray UF 35. Reposition the Manifold so that the Long Elbow and Manifold pipe are in close proximity. In all piping, ensure that the distance between the center line of the Manifold pipe and the center line of the Long Elbow pipe is less than 6 mm.
  • Page 38 A check valve should be prepared and installed between the Air Pipe of the rack and the existing pipes to avoid water reverse flow. The check valve is not included in the parts supplied by Toray. Instruction Manual 06-G-MB2-TUFRack-240801...

    Toray UF (1) Check that all pipes are connected appropriately and flushed out prior to the operation. Fig. 3 shows a standard example of membrane pipe connection. (2) Make sure the feed water valve (V-1), the drainage valve (V-3), and the air-scrubbing valve (V-2) are “closed”.
  • Page 42 Toray UF (1) Close the feed water valve (V-1) and stop the feed water pump. (2) Open the air vent valve (V-4). (3) Close the filtrate water valve (V-5) and open the backwashing valve (V-6) to feed back the filtrate water from the backwashing tank to the membrane module. During backwash, the chemical feed pump can be operated to dose chemical to the backwash water.

  • Page 44: Toray Maintenance Cleaning

    This process is called Toray Maintenance Cleaning (TMC). The TMC is usually held following the backwash and air-scrubbing which does not contain the chemical dosing. The frequency (1) Open the air vent valve (V-4) and the drainage valve (V-3).
  • Page 45 Toray UF (3) As soon as the NaClO is detected in the drainage water, close the drainage valve (V-3). NaClO diluted with UF filtered water is applied to TMC cleaning solution usually. In this case, if the filtered water contains a lot of organic matter, NaClO will be consumed by the organic matter, which may result in a substantial decrease of cleaning efficiency.
