7.2. Filtration
During the "Filtration" phase the unit provides treated water: the untreated water generally flows via via
the feed pump to the inlet valve and then to the ultra filtration module.
The production of treated water can be launched depending on the level of water in the raw water en
clean water tank, depending on the position of the “Filtration start” switch or manually. During
production a service hour counter will be kept which can be read off under the menu option
“Information” (see § 10.5 “Counters” on page 61). A counter will also be kept in connection with
maintenance, if this is programmed (see § 23.2 “Maintenance” on page 95)). This can be read off in
the same window as the service hour counter.
It is possible to turn off the installation manually during the “Filtration” phase, irrespective of the
position of the level switches in the tank(s), or the position of the “Filtration start” switch.
The installation will revert to the “Standby” phase, or to a backwash (if programmed, see § 7.1
“Properties” on page 45).
The “Filtration” phase consists of one step with a duration of each 0-9999 seconds / minutes.
For each stage you can enter what inputs or limits have to be monitored and what outputs have to be
activated. A time has to be entered (0-9999 seconds / minutes) in phases 1, 2, 3 and 5.
If a time of 0 is entered the corresponding phase will be omitted.
Attention!
A permeate valve can be connected to the level in the storage tank.
If the valve is activated during this step, then the valve will be opened or closed, depending on the
level in the stock tank and the setting valve in the permeate valve.
(zie ook § 6.1.4 “Permeate valves” on page 18).
7.3. Filtration 2
With the phase “Filtration 2” it is possible to perform a “top/bottom” filtration.
The filtration cycle will look like this :
or (in case “Backwash 2” is not activated) :
The phase “Filtration 2” is functioning equal to the phase “Filtration”.
