ABSTRACT:
A system for the preparation of a lime slurry and metering of the slurry, which prevents scaling and plugging of equipment and piping. The elimination of scaling and ease of metering are achieved by a combination of process steps in an automated operating sequence. The system is particularly adaptable to the addition of lime to municipal water systems for reduction of the acidity of the water.
