MBBR

o   MBBR (Moving Bed Biofilm Reactor)

 

MBBR technology uses thousands of polyethylene biofilm carriers operating in mixed motion in a blower-aerated wastewater treatment tank under PLC control. Each biocarrier acts as a carrier bed to support the growth and reproduction of heterotrophic and autotrophic bacteria in wastewater. This high density bacterial population provides a high rate of biodegradation within the system while at the same time providing process reliability and ease of use.

 

Considering the operation and maintenance costs, MBBR is very efficient in terms of process selection. It is preferred in many different industrial applications and some of the advantages of the process are as follows.

 

·         Compact: MBBR is a great option for space-constrained facilities because it typically takes up much less space than other systems. MBBR aeration tank can effectively purify the same amount of water as a larger tank used for a more traditional process. In particular, it offers this advantage due to the maximum surface area the media provides for biofilm growth.

·         Simple: Another practical advantage of MBBR is that it is a relatively simple process. MBBR process allows the operator to get operating capability minimizing the role. The training given to Business Operators about the process by Coskun Arıtma staff is important so, they can ensure that everything works properly at the molecular level. 

·         Less Maintenance: MBBR, also referred to as a process that requires less maintenance. Maintenance tasks such as backwash that an operator has to perform in other processes are often unnecessary for the MBBR. This system is largely self-managed, so users can rely on it to function effectively without the need for demanding and constant maintenance.

·         Flexible: Since the microorganisms on the biocarrier respond to sudden changes, MBBR can adapt as required to changing loads and changes in its content. It allows MBBR systems to resist shock loading or a sudden rise in pH levels.

·         Efficient: One of the key advantages of MBBR is its impressive level of efficiency. MBBR system can work much faster to treat water than other alternative methods. 

·       It is an advantageous process for high flow rate. It is easy to increase capacity. This may be possible by increasing the filling degree of the carriers.

·       MBBR is not affected by toxic shock

·       Independent process performance as there is no return line for sludge; MBBR eliminates recirculation, ie active sludge (RAS).

 

 

MBBR Operation and Maintenance

 

The MBBR process is in a dynamic cycle and it does not require backwash or recycle sludge streams. The wastewater treatment tank is cost-effective to operate due to the rough bubble aeration in the aeration zone. Continuous mixing with aeration eliminates clogging and constantly moves biocarriers within the reactor.

 

The maintenance of the MBBR system should be done as written in the operating maintenance manual. MBBR requires qualified personnel for routine monitoring of blower and pump operation. MBBR technology has a self-maintenance mechanism for biofilm level.

 

 

 

Comparison of MBBR and MBR

---

 

The membrane bioreactor is based on a combination of traditional activated sludge and biofilm media. The comparison between MBR and MBBR can be made using the following key criteria:

 

·         MBR's initial investment cost is higher than MBBR.

·         Input TDS value is higher in MBR technology compared to MBBR process.

·         MBBR system does not require chemicals to function like MBR system.

·         MBR process is more difficult to operate than MBBR process.

·         MBR process requires circulation pump and compressor but it is not needed in MBBR.

·         Both systems require blower.

·         In case of power failure, MBR maximum standby time can last up to 24 hours, MBBR is up to 10 hours, then bacteria forms bio-cake form.

·         MBR is better than MBBR at removing complex or toxic substances.

·         MBR treated water quality is superior, but MBBR is suitable for garden irrigation purposes only.
