Abstract

PURPOSE: To prevent the formation of scale from an acid solution containing calcium oxalate by including an acid anion, e.g., sulfamic acid, and aluminum ion in the solution.
CONSTITUTION: To an acid solution containing calcium oxalate, e.g., digesting waste water used in the pulp manufacturing process by a sulfite method, the residual liquid in the distiller after product distillation in the whisky-manufacturing process, etc., a total of 10W10,000ppm (preferably 100W1,000ppm) of aluminum ion and an acid anion, e.g., sulfamic acid, formic acid, glycolic acid, etc., are added in an aluminum ion/anion equivalent ratio of 1:0.33W6 in a manner in which a liquid obtained from the reaction of metallic aluminum and an acid, as described above, in water is added to the said acid solution.
