Industrial Water Softeners and Ion Exchange

Nalco Water provides standard and custom water system dealkalization for boilers operating below 700 psig and where alkalinity can interfere with your process or degrade your product. Dealkalizers will integrate into a complete water treatment system without expensive custom field engineering and programming.

Benefits

• Less Blowdown: High alkalinity promotes boiler foaming and carryover, and causes high amounts of boiler blowdown. When alkalinity is the limiting factor affecting the amount of blowdown, a dealkalizer will increase the cycles of concentrations to reduce blowdown and lower operating costs.
• Reduced Chemical Use:The reduction of blowdown by dealkalization keeps the water treatment chemicals in the boiler longer, minimizing the amount of chemicals required for efficient, non-corrosive operations. Adding dealkalizers to cooling water systems reduces the amount of acid required to treat water and decreases the levels of nitrates and sulfates.
• Less Return-line Corrosion:Carbonate and bicarbonate alkalinities are decomposed by heat in boiler water, releasing carbon dioxide into the steam. This gas combines with the condensed steam in process equipment and return lines to form carbonic acid. This depresses the pH value of the condensate returns and results in corrosive attack on the equipment and piping.
• Better Textile Dyeing:Alkalinity may also produce non-uniform results in dyeing of textiles and other fabrics because of its effect on the pH value of the dye bath.
• Improved Beverage Taste:In beverage manufacturing, alkalinity often produces flat tastes or tends to destroy taste characteristics of flavoring extracts.
