VONTEX MBR Introduce

The Membrane Bioreactor (MBR) is an emerging technology that combines membrane technology with biochemical reactions in wastewater treatment, also known as

membrane-separated activated sludge process. It is a water treatment technology that replaces the secondary sedimentation tank and sand filter in traditional biochemical

treatment processes with membrane filtration. Compared to traditional wastewater treatment biological processes.

VONTEX MBR has the following main characteristics:

1. High Water Quality Effluent:

Due to the efficient retention of membranes, the concentration of suspended solids in the effluent is nearly zero. The retention effect on free bacteria and some difficult-to-degrade large molecular particles increases the concentration of activated sludge in the bioreactor by about 2 to 6 times compared to traditional processes. The membrane effluent is not affected by factors like sludge expansion in the biological reactor. Therefore, MBR produces high-quality effluent that meets the requirements for water reuse.

2.Reduced Sludge Generation:

In traditional activated sludge processes, an extended sludge age leads to an increase in suspended solids in the effluent. However, in MBR, the retention effect of the

membrane ensures that a long sludge age does not compromise effluent quality. The reduction in sludge generation can lower sludge treatment costs, simplify wastewater

treatment processes, and is particularly advantageous for small sewage treatment plants and decentralized facilities.

3.Compact Equipment and Small Footprint:

Due to the high sludge concentration within the bioreactor, the volumetric load can be significantly increased. Additionally, using membrane modules instead of secondarysettling tanks and filtration equipment reduces the required footprint of the MBR compared to conventional biological treatment processes.Membrane bioreactors are classified into two types based on the use of membranes: submerged and external. In the submerged type, membranes are directly immersed in the bioreactor, and treated water is directly extracted from the membrane elements. In the external type, a pump circulates water from the bioreactor through the membrane modules for cross-flow filtration to obtain clean permeate.
