The dissolution efficiency for different stream liming methods

The dissolution efficiency for different stream liming methods is shown to depend upon the following parameters: Particle size distribution; Initial pH-value; Dose intensity; and Degree of wet slurrying. The particle size distribution and the degree of wet slurrying are the only free variables and when they are determined, the others are determined by the conditions at the dosing site. The way to influence the dissolution efficiency, and accordingly the cost of neutralization, will be to vary the particle size distribution of the powder used for dosing. This way the cost optimum may be located.
