ATI A15/66 Residual Sulfite Monitor

O&M Manual

Rev-W (8/10)

CHEMISTRY MODULE

The chemistry module is the heart of the sulfite monitor. Inside this module are the pumps, air

supply, air control instruments, and sensor element required to make an accurate sulfite measurement.

All items are housed in an ABS enclosure, with the main components mounted on the front panel inside

the clear cover. The enclosure is hinged in two places, with the front cover able to swing in either

direction, and the center compartment allowed to swing open on the right hand hinge (open left release

latch). Opening the center compartment allows access to the terminal circuit board, air pump, and

sample and reagent pump wiring.

Sulfite measurement in the chemistry module is done by pumping a small amount of sample out

of the inlet overflow chamber, mixing the sample with sulfuric acid to convert sulfite to sulfur dioxide gas,

and then air stripping the SO

for measurement in the gas phase. Figure 7 provides a view of the

chemistry module components.
