3. Find the Serial Number of the system on the Machine Serial Number Data Sheet and write it in the field
labelled "Machine Serial #".
4. The field labelled "Membrane Location" may be left blank.
5. Find the membrane manufacturer information on the Machine Serial Number Data Sheet and write it into the
field labelled "Membrane Manufacturer".
6. Find the membrane serial number, on the Machine Serial Number Data Sheet, for the membrane being and
write it into the field labelled "Membrane Serial #".
7. After the initial membrane conditioning or after the final end of season cleaning, perform a permeability test.
Record the flow rate measured for the membrane in the Benchmark Flow Rate column. This number can be
filled in the Benchmark Flow Rate field for all subsequent tests until a new Benchmark test is performed.
Performing the permeability test:
1. Perform a rinse (see page 28) then fill the wash tank ⅔ full of permeate by moving the ends of the concentrate
and permeate hoses to the wash tank.
2. Set the valves in the wash cycle position (see page 29).
3. Run the system until the temperature reaches 70°F.
4. Adjust the membrane pressure to 150 psi using valve V2.
5. Record the permeate flow onto the Membrane Permeability Test Sheet in the Measured Flow Rate field, if not
performing a Benchmark Flow Rate test.
A permeability test should be performed after each wash cycle. The test is performed as described above for steps 2
through 6. Compare the flow rate obtained in the test with previous benchmark rates. If the measured difference (see
the calculation below) is 15% or more then further cleaning will be necessary. See the flow chart on page 23.
To calculate the difference to the benchmark, do the following calculation:
1. Subtract the measured flow rate from the benchmark flow rate.
2. Take the result and divide it by the benchmark flow rate.
3. Multiply the answer by 100 and record the result in the Measured Difference field on the Membrane
Permeability Test Sheet.
