Allowing 5 extra So 650 M³Hr 05 kgcm2 blower can be select. To calculate the number of media carriers a facility may need for a wastewater tank it should first determine the organic load of its wastewater. Executive Summary The design outlined in this report is tailored to address the two overriding challenges for wastewater treatment at small wineries.
A design wastewater flow of 10 MGD containing 170 mgL BOD in the primary effluent is to be treated in an MBBR reactor. A degree of freedom is how many independent parameters you need to completely define the state of the system. If you need the mbbr media now or in the future Then please contact.

Slot size should be 70 of the smallest dimension of the biofilm carrier Wedge wire. Process design with MBBR is based on the concept that treatment is achieved with several reactors in series and that each individual reactor is designated for a specific treatment function within the greater treatment scheme. The organic load will be more or less equal to the product of the flow rate and the difference between the influent and effluent concentration.
The first way is very easy and just for Roughly estimated. Flow diagrams are shown for BOD removal and for nitrification including single stage and two stage processes. Overview of MBBR Process Design Calculations.
Further note below points too one more point to be consider the Depth of aeration Tank suppose it is 4 metre depth select 05 or. There are two ways to calculate the volume for the MBBR media to Nitrogen revival BOD removal and COD removal MBBR system. Results from small-scale MBBR tests as well as from commercially operated MBBRs at full scale fish farms are presented.
