MBR-Membrane BioReactor(MBR) for waste water treatment plant (Sewgae Treatment Plant,Effluent Treatment Plant,Wastewater Treatment Plant)

Membrane technology has advanced significantly in the past decade, for both water purification and wastewater treatment. Today, membrane-based systems have become the preferred technology for many potable water purification & treatment applications: Cryptosporidium and Giardia control, color or suspended solids removal, etc.

Most recently, the combination of membranes with the activated sludge process has redefined basic sewage treatment, optimizing the biological treatment operation and yielding a treated effluent that is ideal for reuse.

key advances in membrane technology are at the leading edge of this trend:

a) Quality & bacteria-free effluent with high efficiency in removing organic & inorganic matters

b) Minimum plant size with elimination of conventional element

c)  Stable & efficient biological process is maintained 

WaterCode Membrane for MBR Application

The recent development of less expensive and more efficient hollow fiber membrane from WaterCode has generated new concept in membrane filtration application.

1)  separating bacteria, viruses, colloids and suspended solids,as well as higher molecular weight soluble organics, with pore sizes ranging from 0.1~0.01 micron.

2)  The Hollow Fiber Membranes are used to construct the Immersed Type MBR Membrane.3)  Membranes are immersed directly into the mixed liquor of the biological reactor, reducing the entire treatment process to a single-step operation and replacing the clarifier of a conventional plant with an ultimate barrier for biomass control.

4)  Almost all systems are now based on the significantly more energy efficient, immersed, hollow-fiber membrane, which exhibits a very large membrane surface area.

5)  The large surface area in contact with the process fluid allows operation at very low trans-membrane pressures.This, in turn, reduces fouling of the membrane surface and allows for extended periods of operation with very low maintenance.
