Peracetic Acid Monitor
Peracetic acid (PAA) is an extremely strong
oxidizer widely used in the food industry for
disinfection of piping systems and processing
equipment. It is also used for spray washing of
food products, and for disinfection of cooling
water systems. As a disinfecting agent, PAA
is often preferred because it produces no
harmful breakdown products.
As with any disinfection system, maintaining
proper residual values is the key to effective
pathogen control. To facilitate reliable chemical
feed control, ATI has developed an on-line
monitor cable of providing real time measurement
of low levels of PAA in solution. The Q45/85
Peracetic Acid Monitor uses a direct sensing
polarographic probe mounted in a flowcell to
measure PAA residuals in a flowing water stream.
A permeable diffusion membrane isolates the
sensing electrodes from the measured sample,
providing long-term stability without electrode
fouling problems. The measurement is selective for
PAA, and is not affected by changes in hydrogen
peroxide in solution.
