Method of preparing and purifying nearly saturated lime solutions and lime saturator for carrying out this method

摘要

In a lime saturator, the saturated lime solution, the so-called lime water, is passed through a baffle plate thickener (20) in which an accelerated sedimentation of the impurities it contains and of the calcium carbonates produced is achieved. This enables the output of previous lime saturators to be at least doubled or quadrupled so that the installations can be of substantially smaller construction for the same requirements. IMAGE
