A dealkalizer is a pre-treatment device commonly seen in boiler rooms which is responsible for removing carbonate alkalinity in the feed water before it reaches the boiler. In many cases, the water chemistry parameter which hits its limit first is alkalinity. Thus, by reducing the alkalinity in the feedwater, we can decrease blowdown volume, increase the cycles of concentration, and effectively decrease energy consumption.

Water softening is a process in which water flows through a bed of resin to exchange the hardness ions, calcium and magnesium, for sodium ions. When the resin has reached its capacity for holding hardness ions, the water softener initiates a regeneration cycle. During this cycle, a sodium chloride brine solution flows through the resin and effectively reverses the process by exchanging sodium ions for hardness ions, and flushing the hardness ions down the drain.
