Process for preparing calcite beds constant height control turbid waters.

摘要

Process for the preparation of calcite beds constant height control turbid waters.; This patent relates to a novel process for preparing calcite beds constant height by continuous dosing of calcite by gravity and under water, as well as control of turbid waters that might arise during use of the procedure.; The process is characterized by the fact of employing a structure metering funnels, allowing the continuous application of calcite by gravity and under water and directly over the bed surface. It also has a grill for supporting the dosing funnels, a silo whose floor is made the dosing funnels, a peripheral inner weir below the support structure cones, a filter floor for the uniform distribution of water or air below the bed of calcite and finally, a collection circuit and recirculation of dirty water.
