Treatment system and method for fluids containing particulate matter

摘要

The treatment of a fluid containing a high concentration of particulate matter is enhanced by preventing the accumulation of particulate matter which falls from solution in the lower areas of the treatment vessel. The foregoing is accomplished by withdrawing fluid having a relatively low concentration of particulate matter at the axis of the vessel and subsequently reinjecting the withdrawn fluid as a jet or jets directed downwardly and tangentially to the wall of the vessel in the vicinity of the bottom thereof.
