Generally, dealkalization works best on boilers operating below 700 psi, with feed water containing 50 ppm alkalinity or greater, and make-up water of 1000 gallons or more per day. There are 4 different methods of dealkalization, which can be used to reduce raw water alkalinity: 1) chloride anion dealkalizers, 2) split stream dealkalization, 3) weak acid dealkalization, and 4) reverse osmosis.
