OPERATING PRINCIPLE (1/3)

Meteor™-MBBR combines a biological solution AND a compact separation system (flotation or filtration depending on the cases, see the following pages).

The carbon and nitrogen treatments are provided by a fixed culture on mobile biofilm media.

Depending on the required quality of the effluent, the number of zones used will be adapted differently: there will thus be at least 2 zones and up to 5 zones.

Unlike the Meteor™-IFAS, biofilm media is integrated into each zone of the basin and equipped with retention screens.

OPERATING PRINCIPLE (2/3)

Configuration n° 1: Meteor™-MBBR + High speed flotation Greendaf™

When the level of SS leaving the MBBR > 150 mg/L

Two types of configurations are proposed: they are a function of the levelof suspended solids leaving the MBBR.

Meteor™-MBBR ADVANTAGES Urban

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.
