Process for the preparation of a substantially homogeneous lime water solution

Abstract From the Canadian patent

Abstract of the Disclosure In the preparation of homogeneous lime water solution for use in the purification of waste water, a lime water suspension is used as starting material. The lime water suspension is supplied at the bottom of a compartment in which it is caused to rise in order to leave at the upper part, while passing lamellas during its upward movement. The lamellas are arranged in such a way that they will create a sludge zone at their lower part in the compartment in which, zone the rising lime suspension is filtered whereas they create at, their upper part in the compartment a clarification zone in which fine particles are separated.
