MBR system

The MBR is also known as a Membrane Bio-reactor. A complete MBR system is composed of a biological processing unit and a Membrane separation unit. Compared to traditional aerobic biochemical pool + 2 pond process, MBR system with one to three times higher sludge concentration, greatly strengthened the aerobic biochemical effect, can deep removal of COD, ammonia nitrogen, TP, chromaticity and turbidity of pollutants, cover an area of an area small, water quality and sensory + 2 was better than the traditional aerobic biochemical pool pond process, water quality and reliable. MBR technology has been widely used in industrial and municipal wastewater treatment and upgrading projects.
The MBR system of Feymer Technology adopts the self-produced high-strength PVDF hollow fiber membrane and MBR membrane module, and the advanced system design and integration process can bring economical and reliable products and services to the owner or the general contractor of the project.

The membrane assembly is equipped with its own aerator path, the frame, bottom layer, diversion seal plate and aeration system are made of SUS304/SUS316 stainless steel, and the water-producing branch pipe and aeration branch pipe are all made of SUS304/SUS316 stainless steel. There is no secondary pipe distribution during the installation process. The membrane assembly is strong and durable, with strong anti-seismic and anti-impact ability and stable operation.
The membrane assembler is equipped with special connection and fixed fittings. The membrane assembly is connected to the two ends of the water pipe of the membrane assembler by means of socket. The structure is simple and compact, which reduces the leakage point, improves the sealing, and is more convenient for installation and disassembly.
There are positioning card slots at both ends of the membrane splicer. During the installation process, positioning card slots and the positioning guide rod in the membrane pool are realized, and the hoisting process is easy to operate by sliding down the guide rail.
The aeration branch pipe at the bottom of the film assembly is provided with aeration hole and mud drain hole, which can effectively prevent the aeration pipe from blocking.
