The adoption of membrane bioreactor technology in wastewater treatment equipment represents a new process that combines biological treatment technology with membrane separation technology, replacing the traditional secondary sedimentation tank. It facilitates solid-liquid separation, yielding stable reclaimed water for direct use. Additionally, it maintains high concentrations of microorganisms within the bioreactor, resulting in minimal residual sludge, highly effective removal of ammonia nitrogen, and near-zero suspended solids and turbidity in the effluent. Bacteria and viruses are significantly reduced in the effluent, with low energy consumption and a small land footprint. Research on using membrane bioreactors for wastewater and effluent treatment began in the 1970s in the United States, Japan, South Africa, and many other European countries. The water source is derived from domestic wastewater (such as shower, sink, laundry, kitchen, and toilet drainage) and cooling water.
