DIRECT SUPPORT MAINTENANCE PROCEDURES
MICRO-FILTRATION SYSTEM
MF Assembly Installation:
1. Install the MF assembly onto the TWPS as follows:
a. Carefully lift the top end of the assembly up on end then move into position.
b. Lift the assembly up onto the TWPS, position the bottom mounting brackets over the
bottom spacers, and carefully set the assembly in place.
c. Bolt both bottom mounting brackets to the TWPS frame, but do not tighten (see Figure 6).
d. Bolt both top mounting brackets to the TWPS frame. Tighten the top bracket at the
filtrate end of the MF assembly first, then tighten the top bracket at the feed end.
e. Make sure that the top of the top mounting brackets are flush with the top of the frame.
f. Tighten all remaining mounting bolts and remove the lifting straps.
g. Remove the temporary bracing that was secured between the upper and lower MF
assembly headers at both ends of the assembly.
2. Install the following MF filtrate out components (see Figure 3):
a. Filtrate Drain Valve V-203 and its extension pipe.
b. Check Valve V-912.
c. Air Hose to Check Valve V-912.
d. Upper Filtrate Valve V-201 and the tee pipe section.
e. Air tubing to the actuator on V-201.
f. The expansion joint below Upper Filtrate Valve V-201.
g. The flex strut pipe support between PT-102 and V-202.
h. Electrical wire to Pressure Transmitter PT-102.
i. Filtrate Flow Control Valve V-202.
j. Air tubing to the actuator on V-202.
3. Install the following MF backwash out components (see Figure 2):
a. Shell Drain Valve V-403 and its extension pipe.
b. The expansion joint, the two sanitary clamps, and the pipe section between the MF
Assembly and Lower Shell Out Calve V-402.
c. Upper Backwash Out Valve V-401.
d. The sanitary clamp, flex strut pipe support, and pipe section between the MF Assembly
and valve V-401.
e. Air tubing to the actuator on Upper Backwash Out Valve V-401.
4. Install the following MF feed components (see Figure 1).
a. Lower Feed Inlet Valve V-113 and the expansion joint and 3-in. tee piping above the
valve.
b. The sanitary clamp on the 3-in tee piping.
c. Electrical wire to MF Feed Pressure Transmitter PT-101
d. Check Valve V-911 and Vent Valve V-114 to the upper feed inlet.
e. The 15 psig air hose to Check Valve V-911.
f. Upper Feed Inlet Valve V-112.
5. Trace through the MF system piping to ensure all components are in place and that the
connections are tight.
6. Follow the procedures for startup following a short-term shutdown (see WP 0015).
