ATI has just
released their Optical Dissolved Oxygen (ODO) sensor to compliment their
line of DO monitors that use their galvanic sensor. The ODO can only
be ordered with ATI's famous Air-Blast Auto-Clean option because all optical
sensors still must be clean in order to make accurate measurements.
The ODO uses the fluorescence-quenching technology which has recently become
very popular in waste water treatment plants across the country. The
Q45D transmitter can display and transmit both the dissolved oxygen
measurement and the temperature of the mixed liquor.
ATI has also
recently introduced the Q45N Ammonia Monitor. It is available in
two versions; Total Ammonia and Free Ammonia. The free
ammonia monitor also provides measurements for total ammonia and total monochloramine. ATI has only approved this for use in clean water
applications at this point, but testing is being done on reclaimed
water.
ATI also
offers the industry's only residual-sulfite monitor that is used to
measure the excess bisulfite or sulfur dioxide used to de-chlorinate
reclaimed water. Recent testing by the State of California should
allow WWTP operators to submit the results of this analyzer as proof
that no chlorine left the plant in the near future. The 4-20 mA DC
output from this monitor can be used to minimize the use of bisulfite to
save costs on chemicals.
