Moving Bed Biofilm Reactor (MBBR Media)

The mbbr media, also known as the moving bed biofilm reactor, is used in the aerobic biological fluidized bed process. The mbbr media adopts a three-dimensional hollow structure as an aerobic biological carrier, and the filler is suspended in water during normal operation. It has the characteristics of strong load resistance, high treatment efficiency, long sludge age, less residual sludge, good nitrogen and phosphorus removal effects, and no sludge bulking.

Application

Widely used in municipal, electric power, pharmaceutical, chemical, electroplating, metallurgy, medical, machinery, papermaking, printing and dyeing, food processing, aquaculture, etc.

Working Princple

How MBBR Work

New Bioactive Carrier

Compared with the traditional wastewater treatment system, the moving bed biofilm reactor (MBBR) process technology has the characteristics of high volume load, so the moving bed biofilm reactor (MBBR) process can reduce the pool volume, and the surface charging of our MBBR packing is modified, Suitable for the growth of most microorganisms. Special rough inner surface treatment is adopted to enhance microcell adhesion and rapid biofilm formation.

Features

Moving Bed Biofilm Reactor (MBBR)

Scientific formula, Fast film-hanging

Special materials to enhance biofilm adhesion; Large specific surface area and high porosity ensure more biomass growth; According to the unique structure and shape design of fluid mechanics, the three-dimensional flow dynamics of the carrier in water is strengthened; Add trace elements such as hydrophilic materials to shorten the biofilm formation time from 3 days to 15 days; Excellent impact strength and strong gas shearing ability; Easy to install, easy to cure and requires less space.
