Wastewater treatment plant with MBR technology

Water disposal

PURPOSE
Membrane Bioreactor (MBR) technology is used in municipal and industrial wastewater treatment systems. Wastewater treatment plant with MBR technology is a complex of biological treatment facilities using membrane modules (microiltration, ultrailtration or nanoiltration). For microiltration and ultrailtration membrane complexes membranes with hollow ibers with 4 to 25 mm diameter are used. For microiltration processes plate modules are also used. Spiral membranes are used for nanoiltration membrane modules.
Membranes are made from cellulose acetate, hydrophilic polysulide, polyvinylidene luoride and other modern materials.
THE PRINCIPLE OF OPERATION
After the passage of wastewater from the stages of mechanical and biological treatment, in the membrane tank, the membrane selectively separates the puriied water from other pollutants. The selective separation process is ensured by the presence of micropores
(from 0.001 micron - to 1 micron) on the membrane element. This process makes it possible to exclude the process of removing activated sludge from treatment facilities, which leads to an increase in the oxidative power of bioreactors. Membranes are assembled into a single block with manifolds connected to pumping equipment, a pneumatic aeration system and backwash.
ADVANTAGES
The use of MBR technology in wastewater treatment plants has a number of signiicant advantages:
  • Providing high quality puriied water.
  • Constructions using this technology have a smaller volume of structures and a small building area.
  • Energy eficiency.
  • High reliability and ease of use.
