VESSEL AND SYSTEM FOR BIOLOGICAL REGENERATION OF ION EXCHANGE AND ABSORPTIVE MEDIA |
摘要 |
A system and method for biological regeneration of ion exchange and absorptive media including a vessel configured to contain a bed of contaminated media particles. The vessel includes a first region configured to receive biological regenerating fluid for contacting media particles in the first region at a first volumetric flowrate sufficient to produce a shear force high enough to reduce bio-film thickness on the media particles; a second region configured to receive a portion of biological regenerating fluid from the first region, wherein the portion of biological regenerating fluid in said second region has a second volumetric flowrate lower than the first volumetric flowrate; and a third region configured to receive another portion of biological regenerating fluid from the first region, wherein the another portion of biological regenerating fluid in the third region has a third volumetric flowrate lower than the second volumetric flowrate.
