filtration process
Water filtration in the UFC Series is accomplished
using two modes: Flush Interval Mode, shown as Fi on
the LED Display and Flush Duration Mode (Fd on LED
display). During the Flush Interval, water enters the
inlet and flows through the filter element before exiting
the Permeate outlet as usable product water.
After a certain period of time, depending upon water
quality, the filter has to be cleaned. This is accom-
plished through the Flush Duration Mode. During
this mode, the drain valve opens and flushes the
membrane to remove debris collected inside the
membrane walls.
nOte: both the flush Interval mode and the flush
Duration mode can be automated by programming
the timer. During the flush Interval mode, the valve
is not powered in order to keep water filtering during
a power outage.
