fouled sooner than expected; or the system could be set up to be DP-driven. For a DP-driven system,
the DP threshold would be set low, such that DP-triggered cleanings occur before the filter truly
fouls. This would be desired for systems with relatively clean water, or if the concentration of solids
is significantly varying over time. For this type of system setup, the timed cleaning cycle should be
either set very long or disabled.
4.4.6 Clean In Place (CIP)
The Clean In Place (CIP) allows enhanced cleaning for
especially difficult process water. A single CIP Event
contains one or more CIP cycles.
The CIP should be used when the standard cleaning
capabilities of the skid are not adequate to keep the filter
clean and running stable. Process waters with high levels
of fats, oils, and grease are known to benefit significantly
from the addition of CIP. For unknown process waters,
a good rule of thumb is the 6-hour time window. If
standard skid cleaning tuning allows stable run for over 6 hours before DP issues and filter inspection
shows particle buildup, the CIP is a good option. The event will scrub the screen multiple times with
addition of cleaning solution and/or warm clean water.
The CIP setting screen provides all setpoints associated with the event. Below is an explanation of how
to setup a CIP Event to be as effective as possible.
1. Enable CIP once all physical components are installed, parts are available through CFT.
2. Set the duration of Chemical pump “on” time. This can be set at 0 if no chemicals will be used.
Only use enough chemicals to clean the filter.
3. Set the Dwell time. This is the time the system will circulate the clean water and chemicals. This
setting should be at least 60s for cleaning.
4. Set Pause duration. This is the pause between CIP cycles within a CIP Event and should be in the
10-30s range.
5. Select if a filtrate bump will be used. A filtrate bump will quickly open and close the filtrate valve
to allow some of the cleaning water and chemicals inside the filter. Use this if buildup is occurring
inside the filter after the water passes through the filter membrane.
6. Enable the Schedule to trigger CIP Events regularly based on the Frequency timer. This should be
enabled if the process water has fats, oils, and grease that builds over time.
7. Frequency is the amount of time between triggered CIP Events. A good starting point is 120
minutes. If the filter tends to clog between CIP Events, reduce the timer. If the DP values do not
rise between Events lengthen the timer.
8. Set the number of CIP cycles that will occur within a CIP Event. Two cycles are a good starting
point. Keep the number of cycles as low as possible. If a CIP Event does not fully clean the filter
increase the number of cycles.
9. Shutdown CIP will trigger a CIP Event during a shutdown. This is ideal if the system will be off for
an extended period of time.
10. The CIP can be triggered due to the schedule timer or by a technician at the home screen. The Max
CIP Events/Period will limit how often they can be triggered to keep chemical usage down.
11. The CIP Drain Valve setting can be adjusted to allow more or less of a Hot Water to into system
during the chemical injection step. See the Valves screen Purge CIP Open % setting
