Serial number
(to be fi lled in with a monthly interval)
Conductivity at the outlet
Drain quantity
Stop pressure (default 4 bar)
Start pressure (default 2 bar)
Person in charge

Date of fi rst start-up
Pump working pressure
(default from 5 to 10 bar)
Recovery value
permeate / (permeate+drain) = about 40-60%
Air precharge pressure (default 1.8 bar)
To measure the precharge pressure, it is
advisable to drain the vessel and use a pressure
gauge to measure the air residual pressure
in the same vessel. It is advisable to perform
this operation every month, to guarantee the
hygiene of the stored water.
