Optimize Your Sewage Treatment With MBBR Technology

sewage treatment

A vast quantity of wastewater is generated every day from households, commercial establishments, and industrial settings. Treating organic waste present in the sewage can be challenging as physical and chemical mediums are not quite effective. Thus, biological sewage water treatment processes are generally used to meet effluent standards set. 

However, due to the ever-increasing population, urbanization and industrialization, the performance of treatment plants are affected. Moreover, there are stringent local and national regulations to release the effluent into the environment and to protect public health. MBBR technology is an advanced wastewater technology  that can be used to optimize the sewage treatment plants and boost their efficiency while keeping the costs low. 

What is MBBR Technology?

Moving Bed Biofilm Reactor – MBBR, developed in the 1980s, is a widely used technology due to its efficiency and economical characteristics. The biological wastewater treatment process utilizes a microbial population to break down the organic waste. There are two methods through which it can be  accomplished: Activated Sludge Process – ASP and Trickling Filter method. In the activated sludge process, sludge is supplied with air which helps in the metabolic waste decomposition. In the trickling filter method, a system is used to spray sewage water on a carrier with biofilms. 

MBBR technology combines different aspects of both of these systems and has components such as sludge, aeration tank, plastic carriers and biofilm. The activated sludge aeration system collects sludge on plastic carriers where the aeration process keeps moving the sludge. The large internal surface area of the carrier enables biofilm growth and optimizes the contact between wastewater, bacteria and air, thereby minimizing organic waste. 

Advantages of MBBR technology

MBBR technology used in sewage treatment has several advantages besides being efficient and economical. 

Sludge Retention Time – One of the advantages of using MBBR is that biofilm is not lost in the process. This is mainly due to carriers being kept inside the moving reactor. Thus, when compared to the activated sludge process with a suspended growth system, the sludge retention time is more in systems with MBBR. Also, sludge settling in the clarifier improves with MBBR, and the sludge volume is less compared to other biological processes. 

Hydraulic Retention Time – The features such as moving plastic carriers and concentration of biofilm enables the bioreactor to treat the wastewater influent at a fast rate thus reducing the hydraulic retention time. Depending on the organic load, HRT needs only a few hours in systems with MBBR. 

Load fluctuation monitoring – Most of the biological treatment processes needs monitoring of the fluctuating load. However, in MBBR, the biofilms can adjust according to different volumes and waste loads. It is essential to note that MBBR may not be able to handle a considerably large load. 

Compact – MBBR units are compact when compared to other treatment systems as it contains the large surface area and low volume of biofilms. This is the reason why MBBR can be easily retrofitted into existing Activated Sludge Systems. Plus, MBBR does not need re-circulation lines, and no extra piping or pumps are required. 

If your existing sewage treatment system is not working at peak conditions, it is high time to use MBBR technology. It is essential to boost the treatment process and meet the effluent standards, which will protect the environment as well as public health.
