MBBR

Moving bed biofilm reactor MBBR 

With Moving bed Bioreactor (MBBR)  application we offer advanced wastewater treatment solutions for the industrial and municipal markets. These solutions significantly increase the capacity and efficiency of existing wastewater treatment plants, while minimizing the size of new plant deployments.

The MBBR system consists of an activated sludge aeration system where the sludge is collected on recycled plastic carriers. These carriers have an internal large surface for optimal contact water, air and bacteria.

The bacteria/activated sludge grow on the internal surface of the carriers. The bacteria break down the organic matter from the waste water. The aeration system keeps the carriers with activated sludge in motion. Only the extra amount of bacteria growth, the excess sludge will come separate from the carriers and will flow with the treated water towards the final separator.

The system can consist of a one stage or more stage system, depending on the specific demands. The specific bacteria remain in their own duty tank because of the fact that the carriers remain in only 1 tank, protected by screens.

It uses a combination of activated sludge process i.e. suspended growth and biofilter i.e. attached growth.  It uses the entire tank volume for biomass growth by implementing the carriers for attached growth of biofilm. Movement of carriers is enabled by air bubbles through agitation.

The reactor can be in any shape and support different load depending on carrier filling. MBBR design of reactor depended on the actual wastewater characteristics and locality.  The plants come either with vertical or horizontal mounted rectangular mesh sieves. The reactor can also be fitted with cylindrical bar sieves.

Biological Oxygen Demand (BOD) removal – It requires only one wastewater tank with the MBBR and clarification.

Nitrification – It uses two tanks one for BOD removal and the other for nitrification.

Denitrification – It uses four aeration tanks in this order before emptying in the clarification with pre denitrification, BOD reduction, nitrification and post denitrification.
