Classification and management requirements for MBBR biofilter media
- Jan 03, 2019 -

MBBR biological filter packing is directly added, no need to add new structures directly, no need to add new structures, especially suitable for sewage treatment plant upgrade and deep denitrification treatment when operating, this technology is also used for integrated equipment construction It can effectively save 1/3-1/2 of the floor space and manage more easily than the conventional process.

Classification of MBBR biofilter fillers

According to the different processes of sewage treatment, it is divided into aerobic, anoxic, and anaerobic process fillers; and for high-concentration refractory wastewater, the filler can be personalized.

Mature film identification

Visual judgment:

The biofilm is evenly distributed on the surface of the carrier. The closer it is to the surface of the carrier, the denser it is. On the contrary, the looser the carrier, the darker the color of the carrier, indicating that the carrier film has entered the maturity stage.

Microscopic judgment:

The biofilm structure is dense, the microbial species are diverse, and the fixed ciliates, bell worms, and worms are mostly present. A small number of rotifers and swimming ciliates indicate the biofilm maturity.
