1.2.5 Put the selection switch “manual-0-auto” (12S3) into “auto”
position.
Now:
- Blower(s) G1.1 (or G1.2 or … if installed) starts running
- Pump P6.1 (or P6.2 or… if installed) is in stand-by
mode
- Pump P1.1 (P1.2, P1.3, … if installed) starts running
- Pump P2 starts running (because of STP’s control tank
level)
- Pump P5 (if installed) starts running depending on
buffer tank level and the STP’s control tank level
Vacuum pumps VP1 and VP2 (if installed) are ready for
operation (please refer to commissioning guide and manual of
the vacuum pumps)
1.2.6 The BMSU loading pump (P2) is now feeding water from the
STP’s control tank into the BMSU, and the BMSU overflow
pump (P1) is circulating the water through the membrane.
After a short while a permeat flow will be visible inside the flow-
indicator FI1.1 (FI1.2,…).
As soon as all remaining air-contents from the membrane have
disappeared (pumped out) there will be a steady permeate-flow
visible on the flow indicator.
1.2.7 The PL-Unit (if installed) needs a counter pressureof 1,5-2 bar
(please refer to the name plate of the PL-Unit). If this is not
available in the overboard pipe system, the flow needs to be
throttled by using valve H16.
If the counter pressure is adjusted, the pressure on the suction
side of the PL-pump needs to be adjusted to -0,1 - -0,5bar by
using valve H17 (if installed).
During the normal operation those adjustments do not need to
be adjusted again.
1.2.8 Check the correct function of the transfer pump P5 by
observing the level of the control tank via sight glass.
1.2.9 Check the correct function of the BMSU side cleaning, by
pressing the push button F2 “manual side cleaning”.
