  • 1. Meteor™- MBBR BIOLOGICAL PURIFICATION OF WASTEWATER BY MOVING BED CULTURES URBAN WASTEWATERP-PPT-ER-011-EN-1107 COMPLETE TREATMENT OF WASTEWATER WITH A VERY COMPACT FOOTPRINT

  • 3. UrbanWastewater Meteor™ RANGE Meteor™ Meteor™ is a biological treatment solution developed by MBBR Degrémont for the remediation of wastewater using fluidized cultures grown on biofilm media. Meteor™ RANGE Specific Preferential Concentration Models features of the Positioning in free sludge Strong points process For new facilities (biological basin) • Very compact – Biomass in the compact separation (CMDF MBBR form of biofilm NTK 400 mg/L – DAF) • High load variation • Mixed culture – less support Mixed biomass than in MBBR IFAS (free + biofilm) Total N 2 g/L • Renovation – increase in treatment quality 3
  • 4. OPERATING PRINCIPLE (1/3)Meteor™-MBBR combines a biological solution AND a compactseparation system (flotation or filtration depending on the cases,see the following pages).The carbon and nitrogen treatments are provided by a fixed culture onmobile biofilm media.Depending on the required quality of the effluent, the number of zonesused will be adapted differently: there will thus be at least 2 zones andup to 5 zones. TO SEPARATOR Unlike the Meteor™-IFAS, biofilm media is integrated into each zone of the basin and equipped with retention screens. 4
  • 5. OPERATING PRINCIPLE (2/3) Two types of configurations are proposed: they are a function of the level of suspended solids leaving the MBBR. Configuration n° 1: Meteor™-MBBR + High speed flotation Greendaf™ When the level of SS leaving the MBBR > 150 mg/LPRETREATEDAND SCREENEDWATER TO SEPARATOR + 5
  • 6. OPERATING PRINCIPLE (3/3) Configuration n° 2: Meteor™-MBBR + Filtration Compakblue™When the level of SS leaving the MBBR < 150 mg/L (generally in thecase of primary settling) + 6
  • 7. UrbanWastewater COMPONENT PARTS – RETAINING SCREEN Meteor™ Protection for the MBBR environment 2 versions: In an aerated zone: In an anoxic zone: The screen allows for the retaining of the supports in the treatment zone. 7
  • 8. Urbanwastewater COMPONENT PARTS – AERATION Meteor™ MBBR 2 types of aeration to be adapted to each situation Medium bubbles Fine bubbles 8
  • 9. Urbanwastewater COMPONENT PARTS – THE MEDIA Meteor™ MBBR 3 different medias for case-by-case adaptation. NAME Meteor 660 Meteor 515 Meteor 450 9
  • 10. Urbanwastewater Meteor™-MBBR ADVANTAGES Meteor™ MBBR FLEXIBLE USE: • Works continuously and does not require any washing of the materials, • Modular and upgradable equipment that can be adapted to all plant sizes and all treatment objectives (pre-denitrification, treatment of carbon, nitrification, post-denitrification), • Allows for substantial load variations, so its use is perfectly suited to tourist areas, • Adapted to the treatment of low-temperature effluents. PERFORMANCE & ENVIRONMENT: • Optimal compactness (of the biological unit and the separator), • Allows for targeted treatment and therefore optimizes nutrients (nitrogen, carbon), • Includes reactors that reproduce natural purification, • Meets the strictest discharge standards. 10
