As in other chemical water softening technologies, the objective of the lime–soda ash process is to precipitate polyvalent cations from solution by pH adjustment. In water treatment applications, Ca2+ and Mg2+ are the two major cations of concern, though Fe2+, Fe3+, Al3+, and Mn2+ may ...
Lime plays two important roles in the production of soda ash and sodium hydroxide. One of the major sources of soda ash (Na2 CO3) and caustic soda (NaOH) in North America involves the refining of naturally occurring trona ores. These ores are mixtures of carbonates, bicarbonates and ...
