Municipal sewage and waste water treatment plant with FS MBR remove SS and biodegrade

MBR introduction

The Membrane bioreactor (MBR) removes not only suspended solids (SS) but also substances difficult to biodegrade such as detergent, by taking advantage of its longer Sludge Retention Time (SRT). This enables the treated water to be re-used.

MBR can purify domestic and industrial wastewater by combining the action of microorganisms with the separation of solids from liquids using membranes. The membrane removes suspended solids and pathogenic e-coli bacteria, so that the effluent water can be re-used as toilet flushing water or sprinkling water

Specifications

Above datas are tested at standard single sheet FS MBR with municipal waste water at 25 ℃ and operation pressure 10Kpa.

Key features

• The excellent chemical stability, fouling resistance and mechanical strength
• The pore size is less than 0.1 micron, the improved effective membrane area ensures large permeate flux and quality
• The perfect fouling resistance due to the asymmetric structure. This features low membrane resistance, good fouling resistance. large particles from rosion of air, won't enter into the membrane. The small particles through the membrane, won't be stranded in the membrane pore and quickly flow through the large hole out of the membrane
• The FS MBR can be with higher concentration of activated sludge (MLSS is larger than 8000 mg / L). Mebrane surface area doesn't plot the mude and no lose of effective membrane area. Air and water erosion on the membrane surface remove the membrane surface dirty
• The FS membrane is firmly welded on high-intensity support plate, it does not appear the phenomenon of broken wires as hollow fiber so permeate water quality stable. This is very important for the waste water treatment application followed by NF / RO membrane recycle process.
