MABR (Membrane Aerated Biofilm Reactor)

MABR (Membrane Aerated Biofilm Reactor)

MABR (Membrane Aerated Biofilm Reactor) is a new wastewater treatment process with a combination of gas separation membrane technology and fixed biofilm. Oxygen is transferred in the form of oxygen molecules through the MABR membrane for bubble-free and efficient transport. The different layers of biofilms (aerobic nitrifying bacteria-anoxic denitrifying bacteria) are formed from the inside to outside on the membrane surface, which can achieve high-efficiency

Description

MEMBRANE AERATED BIOFILM REACTOR

MABR (Membrane Aerated Biofilm Reactor) is a new wastewater treatment process with a combination of gas separation membrane technology and fixed biofilm. Oxygen is transferred in the form of oxygen molecules through the MABR membrane for bubble-free and efficient transport. The different layers of biofilms (aerobic nitrifying bacteria-anoxic denitrifying bacteria) are formed from the inside to outside on the membrane surface, which can achieve high-efficiency

simultaneous nitrification and denitrification in the same reactor, so as to achieve deep denitrification and denitrification of sewage. It is a new type of wastewater treatment process with high efficiency, low energy consumption, and low sludge yielding.

MABR Main Features

  1. Molecular oxygen transmission, the oxygen utilization rate is 2-4 times that of traditional aeration;

2Dense non-porous structure, no membrane clogging.

3Bubbleless oxygen transfer, environment friendly;

4Low-pressure less flow air supply, energy saving up to 50-70%;

5TN removal is prioritized, carbon source addition is reduced

6Simultaneous nitrification/denitrification, Minimize/Cancel RAS;

7Sludge yielding reduce 30-50%

8Operating temperature:-40℃~120℃,no location limit.
