Low Alkalinity In Boiler Water


Alkalinity | Dealkalizers - Process Water | Water Purification

Generally dealkalization can be used to treat water in boilers operating at less than 700 psi with feedwater containing less than or equal to 50 ppm alkalinity and with make-up of 1000 gallons or more per day. Makeup water is the water added to the boiler to offset water lost due to steam and blowdown.
