Boiler water Treatment

(OP)
Hello all

i work for a food manufacturing firm and we have been having problems with our boiler water quality. We are struggling to keep the OH and P alkalinities in spec, and this is not easy given that the water softener is down. given below are some of the results we have been obtaining.

May someone reccommend food grade chemicals or methods which we can apply to solve this problem. the boiler is a 12t/hr fire tube boiler.
