3 | Function
The GENO-mat filter systems for the filtration of impurities / partial
deacidification work with an active insoluble catalytic filter material. A
central control valve automatically controls the operating cycles fil-
tration, backwash and first filtrate.
3.1 Filteration
The raw water enters the exchanger tank via the raw water inlet and
flows through the filter material from top to bottom. According to the
filter type, the dirty water is filtered from top to bottom. The filtered
pure water is then directed via the lower distributing nozzle and the
riser pipe through the pure water outlet into the piping system.
3.2 Backwash
During the backwash process, the filter bed is forcibly flushed from
bottom to top and thus loosened up. Impurities retained during the
filtration process are washed out via the drain outlet at the control
valve. The filter system must be backwashed every 6 days at the
latest (for the setting refer to chapter F).
3.3 First filtrate
By an automatic switch-over of the central control valve, the filter
bed will forcibly be flushed from top to bottom. This first filtrate is
discharged to the drain and afterwards the filter system is ready for
operation once again.
3.4 Control unit
The GENO-mat filter systems / deacidification systems are time-
controlled via an electrical timer.
In order to properly use the automatic timer control, the time interval
between two filter sequences (backwash interval in days) must be
set.
