Moving Bed Biological Reactor

Listing ID #710750

We offer highly efficient Moving Bed Biological Reactor or submerged aerobic fixed film reactor. We are engaged in providing clients Moving Bed Biological Reactor that primarily removes wastewater in three stages that are primary settlement, aeration and final settlement. This robust treatment plant is simple in design and suitable for broad range of applications. This system can be supplied and installed with air blowers. Apart from this, minimum civil work is required.
Work Process :

• Primary Settlement : initial settlement of wastewater and separation of gross solids occurs in the primary settlement tank. The gross solids in the wastewater form sludge at the bottom of the tank and lighter social debris forms a crust on the surface. The settled liquor that is contained between the sludge and crust passes forward through an outlet filter for treatment in the aeration chamber.
• Aeration : the moving bed biological reactor (MBBR) employs a submerged media onto which micro-organisms attach. This biomass requires oxygen to flourish. This is supplied by aerating the liquid in the chamber. The biomass retained on the media provides effective treatment for effluent. The media are kept in motion by the course bubble aeration. The air introduced into the tank ensures thorough mixing and turnover of the media within the reactor.
• Final Settlement : the effluent passes forward for the final stage of treatment and enters the final settlement tank through a stilling well. This slows the velocity of the effluent and allows any remaining fine solids to settle. The base of the tank is coned allowing final settlement of the effluent to take place with minimal disturbance to any settled particles. The return sludge pump is located at the base of the tank and any remaining fine solids are returned via a sludge return line to the primary settlement tank. The treated effluent emerges from the system through the outlet for disposal.

Benefits Of MBBR :

• High treated effluent quality
• Small footprint
• Robust treatment plant (concrete tanks)
• Below ground installation simplicity of design, installation & operation
• Suitable for a broad range of applications
• The MBBR treatment process can be provided for a new sewage treatment works or for retrofitting or upgrading existing wastewater treatment plants where a higher treated effluent.

Features included as standard in the MBBR treatment plant :

• Pre-cast concrete tanks
• Air blowers supplied and installed
• Minimum civil work required
