be used without written authorization by NOBEL Technical Department.
The activated-carbon bed also works as a mechanic filter same way of quartz-sand bed.
Although this working should be avoided, it can happen that the pressure drop of activated-
carbon bed reaches a value of 1 bar (100 kPa); in this case the backwashing of the filtering bed
is required.
The equipment allows to schedule the days (how often) and time of day for the regeneration,
same way of quartz-sand filters, as above explained.
It is recommended to run the regeneration only when it is strictly required: the backwashing
causes the mixing of the bed and could displace the higher layers of activated carbon (most
polluted) from the top to the bottom of the column.
During regeneration the water supplying is completely inhibited by means of a membrane
valve mounted on the outlet line.
