20110168634 | PROCEDURE FOR THE PREPARATION OF CONSTANT HEIGHT CALCITE BEDS WITH TURBID WATER CONTROL - The present patent refers to a new procedure for the preparation of constant height calcite beds through the continuous dosing of calcite by gravity under water, along with the control of whatever turbid waters might be generated during use of the procedure. The procedure is characterized by the use of a structure of dosing cones that allows for the continuous dosing of calcite by gravity under water and directly onto the surface of the bed. It also incorporates a grid for supporting the dosing cones, a silo with a floor made up of these dosing cones, an inner perimetric spillway below the cone support structure, a filtering floor for the uniform distribution of water or air below the calcite bed and, finally, a turbid water collection and recirculation circuit. | 07-14-2011 |
