INTEGERATED SLUDGE and MBBR

PROCESS PRINCIPLE

         MBBR process is a new kind of high efficiency wastewater treatment technology, which combines MBBR process with

traditional activated sludge process, and contains both advantages of MBBR process and activated sludge process. Suspension

carrier fillers were added to anaerobic and aerobic reactors, which could removal organic pollutant effectively, strengthening

nitrification and denitrification, achieving simultaneous nitrogen and phosphorus removal.

PROCESS ADVANTAGES

 · Stable treatment effect and quite good to meet the requirement of discharge standard (Grade-I A or Ground quasi-IV), with simultaneous nitrogen and phosphorus removal.

 · High volume loading could stimulate the retrofitting from Grade-II to Grade-I A and higher standard in the existing reaction tank. 

 · High resistance to shock loadings.

 · Sustainable upgrading, the largest filling ration is 67%, meeting the need for batch upgrade.

 · Embedded retrofitting, no need to transform existing technological process, reaction tank volume and operation mode, short renovation time.

 · Long life, easy operation, suspension carriers’ life more than 15 years.

APPLICATION SCOPE

           For the retrofitting of the existing wastewater treatment plant, MBBR could be widely applied to all kinds of activatedsludge operation processes such as A2/O, oxidation ditch, SBR and Biolake.

           For newly built sewage treatment plants, the application of MBBR process can ensure the stability of operation, and continuous upgrading can be carried out by adding fillers, which has the advantages of low investment cost and convenient transformation.
