RAS Shock Resistance MBBR Bio Media FDA Virgin Grade

Product Description

The MBBR system is considered a biofilm process. Other conventional biofilm processes for wastewater treatment are calledtrickling filter, rotating biological contactor (RBC)and biological aerated filter (BAF). Biofilm processes in general require less space thanactivated sludgesystems because the biomass is more concentrated, and the efficiency of the system is less dependent on the final sludge separation. A disadvantage with other biofilm processes is that they experiencebiocloggingand build-up of headloss.

MBBR systems don't need a recycling of the sludge, which is the case with activated sludge systems.

The MBBR system is often installed as a retrofit of existing activated sludge tanks to increase the capacity of the existing system. The degree of filling of carriers can be adapted to the specific situation and the desired capacity. Thus an existing treatment plant can increase its capacity without increasing the footprint by constructing new tanks.

When constructing the filling degree can be set to, for example, 40% in the beginning, and later be increased to 70% by filling more carriers. Examples of situations can be population increase in a city for a municipal wastewater treatment plant or increased wastewater production from an industrial factory.

The main features of MBBR :

①High processing load; 　　

②Small oxidation tank volume, reducing capital investment; 　　

③The MBBR process does not require sludge return equipment and backwashing equipment, reducing equipment investment, simple operation, and reducing sewage 　　

④The MBBR process has a low sludge yield, which reduces the cost of sludge disposal; 　　

⑤The MBBR process does not require filler supports and is directly added, which saves installation time and costs.
