When it comes to MBR flat sheet membrane flux in MBR (membrane bioreactor) wastewater treatment, there are several key factors to consider. These factors will be explained in detail below:
1. Membrane material: The flat membrane used in MBR usually uses polymer materials , such as polyester, polypropylene, etc. Membranes of different materials have different pore sizes and structural properties, which directly affect flux. Generally speaking, membranes with larger pore sizes can achieve higher flux, but may have an impact on the solid-liquid separation effect.
2. Operating conditions: Operating conditions refer to the process parameters when the MBR system is running, including temperature, bubble aeration mode, reflux ratio, sewage inlet flow rate and concentration, etc. These operating conditions will affect the membrane flux. For example, appropriate temperature and bubble aeration can well control the accumulation of contaminants on the membrane surface and increase flux.
3. Wastewater characteristics: The characteristics of wastewater will also affect the flux of MBR flat membrane. These include suspended solids concentration, colloidal particles, grease and organic matter content, etc. High concentrations of suspended solids and organic loading may cause clogging and fouling of the membrane, thereby reducing flux. Therefore, wastewater characteristics need to be fully considered when designing the MBR system.
Based on the above factors, under normal circumstances, the flux of MBR flat membrane is 10-30 L/(m²·h) within the range. However, the specific flux depends on the operating and design parameters of the system and may vary for different applications. In practice, throughput needs to be determined through experimentation and optimization.
It should be noted that the flux of MBR flat membrane may decrease over time. This is caused by problems such as the accumulation of contaminants on the membrane surface, the growth of biofilm, and the clogging of membrane pores. Regular maintenance and cleaning are key measures to maintain good throughput and system performance. With proper maintenance and cleaning, membrane flux can be restored and membrane life extended.
