Claim Text:
1. A system for controlling oxidation of sulfites in a slurry, comprising: a tank having an inlet for receiving a slurry and an inlet for receiving a gas, the inlet for receiving the gas configured so that at least a portion of the gas received in the tank is dispersed through at least a portion of the slurry received in the tank; a sulfite concentration measuring sensor arranged in contact with the slurry received in the tank to real time measure a sulfite concentration S software executing on the controller for generating a signal indicative of an adjustment of a flow rate of gas into the tank based at least in part on the sulfite concentration measuring sensor transmitted real time sulfite concentration S an inlet operative for supplying ammonia, sodium or magnesium cations to the slurry to achieve a slurry alkalinity for bisulfite formation therein.
