Solution
Special PH sensor with retractable assembly to suit slurry
process conditions of Suphala Slurry. The assembly operates
in auto mode and pushes the sensor into the reactor only
when the pH needs to be measured. It is retracted into the
holder chamber and flushed. This increase the life of the pH
sensor.
Operation of control valve for ammonia dosing via a PLC
based control system, based on the algorithm and logic
developed for addition of ammonia to the reactor. The set
point control is available locally for the plant operator with
password protection.
