Membrane bioreactor technology commonly used in environmental engineering wastewater treatment

3.1 EGSB-MBR combination technology

      The EGSB-MBR combination technology simply means that EGSB and MBR technologies complement each other's strengths and weaknesses. The advantage of EGSB reactor is its high treatment efficiency, which can basically remove chemical oxygen demand from water. However, this technology is difficult to remove suspended solids, ammonia, etc. from water, but MBR can make up for it well.

3.2 Combination technology of air flotation/aerated biofilter/membrane bioreactor

      Wastewater treatment is a complex task that sometimes requires combining existing technologies to achieve the goal of purifying water. For difficult to remove pollutants such as detergents and colloids in water, the use of combination technology can greatly reduce the content of harmful substances, greatly reduce the workload of subsequent sewage treatment work, and also reduce the degree of membrane pollution.

3.3 Internal Circulation Dynamic Bioreaction Technology

      In recent years, relevant technicians have transformed membrane bioreactor devices, giving rise to a new technology - dynamic internal circulation reaction technology. This dynamic membrane bioreactor uses relatively inexpensive microgrid materials as the biofilm, and through activated sludge filtration, lateral aeration is chosen during dynamic membrane biological treatment. Choosing this form can significantly reduce the decrease in cross flow velocity and the occurrence of short flow inside the reactor.
