MBBR Media K1 K3 MBBR Bio Filter Media For Sewage
Product describe：
MBBR Media K1 K3 MBBR Bio Filter Media For Sewage A schematic of the Moving Bed Biofilm Reactor MBBR process for BOD removal is shown below.
It is this high-density population of bacteria that achieves high-rate biodegradation within the system, while also offering process reliability and ease of operation. Medium or coarse bubble diffusers uniformly placed at the bottom of the reactor maintains a dissolved oxygen (DO) concentration of > 2.5-3 mg/L for BOD removal. Still higher DO concentrations are maintained for nitrification. To retain the media flowing out of the tank, screens are placed on the downstream walls. A clarifier or a DAF is placed downstream of the MBBR tank to separate the biomass and the solids from the wastewater. No sludge recycle is required for this process. A typical MBR Media is shown below.
The required aeration within the filter is established by using a rigid aeration grid. The grit is fed by both high pressured air releasing air bubbles at the bottom of the filter bed, that move upwards. Oxygen uptake by the biomass on the moving/floating media is highly efficient, as these are moving slowly downwards, creating a moving bed vortex.

MBBR Media K1 K3 MBBR Bio Filter Media For Sewage In this study, the performance of the MBBR at a lab-scale during batch and continuous operations was addressed while changing the Organic Load (OL), the Filling Ratio (FR) and the Hydraulic Retention Time (HRT). The MBBR shows to be more stable when a FR of 40% is used, which allows a reduction of the HRT from 8 to 4 h, reaching a COD removal of 95%, allowing a reduction on the energy consumption, compared to the conventional processes.
Actually, one of the best parts about the MBBR biofilm reactor process is how flexible it is, with minimum operator intervention. The highly concentrated biofilm, that remains consistently within the tank, self adjusts to react to and metabolize the increased load of sewage.
In the past, conventional activated sludge is widely used as biological treatment due to cost-friendly factor. Nowadays, a lot of modifications and upgrading works have been made to meet strict rules and regulations requirement for discharging treated wastewater into the natural water bodies Compact wastewater treatment plants that produce an effluent of high standard in the presence of smaller footprint and minimize waste is increasingly become worldwide concern particularly in the densely populated areas where limited space is available for the treatment plants. Biological processes particularly MBBR and IFAS is one of the biological treatment processes in wastewater treatment which offer compact treatment plant design to overcome the drawbacks of CAS process and produce higher quality effluent even in smaller foot print.
