In systems programmed with BASE WASH cleaning cycle,
TUBING WASH BASE 1, ACID and BASE 2 settings define the
quantity of acid and base reagents (in pulses) used to wash the
sample lines which include tubing located between the Sample
(ARS) Valve and the Bypass port, and each stream specific
tubing.
REACTOR WASH TIME 100s
CLEANING ACID 3p
CLEANING BASE 30p
CLEANING OXID. 30s, 10l/h
NEUTRALIZATION ACID 20p
NEUTRALIZATION BASE 18p
NEUTRALIZATION 30s, 10l/h
REACTOR WASH TIME determines the length of time (100
seconds by default) the cleaning liquid is mixed during the
REACTOR WASH cleaning cycle.
REACTOR WASH TIME setting is not applicable for REVERSE
WASH, FULL REACTION and BASE WASH cleaning cycles.
In systems programmed with BASE WASH cycle, when the TOC
results are above 15000 mgC/l for CLEANING ALARM
described above, BioTector injects the programmed CLEANING
ACID and CLEANING BASE reagents (in pulses) into the reactor
and oxidizes these reagents with the CLEANING OXIDATION
time and flow setting (30s at 10l/h by default). When the reactor
wash cycle is complete, the reactor pH is neutralized with the
NEUTRALIZATION ACID and NEUTRALIZATION BASE
injections (in pulses). The neutralization reagents are mixed with
the NEUTRALIZATION time and flow setting (30s at 10l/h by
default).
