Reasons and countermeasures for the decrease in MBR penetration rate
MBR (Membrane Bioreactor), as an efficient wastewater treatment technology, is widely used in industrial and urban wastewater treatment fields. However, as the usage time increases, there may sometimes be a decrease in MBR permeability, which affects the treatment effect. Let’s explore together the reasons for the decrease in MBR permeability and corresponding solutions.
1.Reasons for the decrease in MBR penetration rate
Membrane blockage: After prolonged operation, dirt, biofilm and other substances may accumulate on the surface of the membrane, leading to membrane blockage and affecting permeability.
Bubble blockage: Bubbles gather in the membrane pores, forming bubble blockage, causing a decrease in membrane permeability and permeability.
Expansion of biofilm: Excessive growth or expansion of biofilm can clog membrane pores, reduce water permeability, and lead to a decrease in permeability.
Incomplete chemical cleaning: Incomplete chemical cleaning of membrane components or residual cleaning agents can affect membrane permeability, leading to a decrease in permeability.
2.Response methods for MBR penetration rate decline
Regular cleaning: Chemical cleaning of MBR membrane components is carried out regularly to remove dirt and biofilm, restore membrane permeability, and improve permeability.
Bubble control: Optimize the gas supply system, control bubble generation and distribution, reduce bubble blockage, and maintain membrane permeability.
Biofilm control: Strengthen the monitoring and management of biofilms, avoid excessive growth of biofilms, timely remove excess biofilms, and maintain the normal operation of membranes.
Improve the cleaning procedure: Optimize the membrane cleaning procedure to ensure thorough cleaning, avoid residual cleaning agents, and improve the service life and permeability of the membrane.
By using the above methods, the problem of decreasing MBR penetration rate can be effectively solved, ensuring the efficient operation of sewage treatment systems.
