Boiler feed softeners, cooling tower treatment, plant-wide softening, and dealkalization systems. Prevent scale, protect equipment, and extend service life.
Calcium and magnesium in process water form scale deposits on heat exchange surfaces — just 1/8 inch of scale reduces heat transfer efficiency by 25%, forcing equipment to consume more energy and shortening service life. Industrial softening systems prevent this through ion exchange, replacing hardness ions with sodium.
Boiler feed softeners are typically configured as alternating dual-tank systems to ensure uninterrupted soft water supply during regeneration cycles. Key design inputs include boiler horsepower, condensate return percentage, operating steam pressure (higher pressures require stricter quality), and raw water hardness.
Dealkalizers reduce bicarbonate alkalinity that converts to CO₂ in steam systems, causing carbonic acid corrosion in condensate lines. Chloride-cycle dealkalizers are the most common choice; acid-regenerated systems are used where very low residual alkalinity is required. Both can be integrated with softening in a single treatment train.
