MBR (Membrane Bioreactor) is an advanced wastewater treatment technology that achieves the separation of liquids from solids by using semi-permeable membranes and maintains a high concentration of microbial communities on the liquid side. The main differences between the MBR curtain and the MBR process are as follows:
1.Membrane material: MBR curtain membrane usually uses polyethylene film, polypropylene membrane, etc., while MBR process can use different types of membrane materials, including hollow fiber membrane, flat membrane, etc.
2.Hydraulic conditions: MBR curtain membranes typically operate at static or micro flow rates, while the MBR process can achieve different hydraulic conditions by adjusting the water flow rate.
3.Sludge suspended solids treatment: MBR curtain membrane intercepts sludge suspended solids on the liquid side through the filtration action of the membrane, so as to achieve sewage purification. The MBR process separates the sludge suspended solids by means of sedimentation tanks or other sedimentation equipment.
4.Design structure: MBR curtain membranes usually use vertically arranged membrane curtains to remove the buildup on the membrane surface by gas flushing or chemical cleaning. The MBR process can be designed with different structures, such as flat plates, hollow fiber modules, etc.
Overall, MBR curtain membrane is a specific type of MBR technology that has a simple structure and way of operation. The MBR process, on the other hand, covers a wider range of membrane materials and equipment configurations, and can be optimized according to specific application needs.
