5.13 Bleach Injection System (BLIS) operation
The BLIS sends bleach into the pump manifold just below the DO sensor. The bleach
prevents biological fouling on the DO sensor membrane.
Adjust the BLIS for the type of environment it will be deployed in.
•
BLIS Operation
—Set to "On." When the conductivity value shows that the sensor is
in water, the BLIS sends bleach to the pump manifold after the first sample of every
hour.
•
Purge when in situ
—Set to "Yes." When the sensor is in situ, the BLIS pump
operates 20 times to remove air or water from the BLIS tubing. This makes sure a
sufficient quantity of bleach is available to protect the DO sensor.
•
BLIS Interval
—The BLIS sends the selected quantity of bleach after the first sample
of every hour.
•
BLIS Injection Volume
—Select the quantity of bleach to be used in 9 µL increments.
The manufacturer recommends a minimum of 36 µL.
•
BLIS Volume Used
—The host software makes a continuous estimate of the quantity
of bleach used in relation to the quantity selected by the user.
