Alternating service
A two filter system normally runs in
alternating mode, with one filter
supplying treated water while the other
filter is in reserve (standby) or is being
regenerated.
Parallel service
If high output performance is required
over a short period, a two filter system
can also be run in parallel. Here both
filters supply treated water at the same
time except during regeneration.
When the controller is programmed for parallel service, it can be switched back and
forward between alternating and parallel modes using the special function
“Switching from parallel to alternate”.
For parallel service you can determine
whether the filters are to be regenerated
one after the other or at offset intervals.
If you select “Y” both filters will be
regenerated immediately one after the other, since both filters are saturated.
For example: silica filter systems activated by time intervals or differential pressure
gauges.
NOTE: For water softening systems it must be ensured that brine is available
(reservoir tank).
If you select “N” only the saturated filter in service will be regenerated. At this point
the other filter still has 50% of its capacity.
For example: quantity controlled water softening systems with a shared brine
container.
Series switching
Select series switching when the filters
in a two filter system were set up in
series.
For example: single flow partial
desalination system with an H exchanger and a Na exchanger.
For partial desalination systems the
service life of the Na exchanger can be
several times longer than that of the H
exchanger.
You can therefore enter a regeneration relation between 1:1 and 1:9.
For example, if you enter “1:2” the Na exchanger is only regenerated after every
second regeneration of the H exchanger.
Service valve
In alternating service or offset parallel
service one filter continues to supply
treated water while the other is
regenerating.
If it too becomes saturated because the amounts drawn off are too large, the
message “capacity exceeded” is displayed. You can determine whether in that
case the second valve is to stay open, with the possibility that it will supply
incompletely treated water (Y/N) or whether tat the valve should close (Y/N), with
the result that no water flows to the user until the regeneration is completed.
