What are the Pros and cons of MBBR Technology?
A biological wastewater treatment technique. A moving bed biofilm reactor is a natural process that employs biofilm to remove trash from wastewater. In the water, microorganisms connected to media devour undesired waste, leaving the water cleaner.This procedure eliminates organic compounds, as assessed by biochemical oxygen demand (BOD), and achieves nitrification and denitrification in a safe and environmentally friendly manner.
Although MBBR can be used on its own, it is frequently used as part of a larger wastewater treatment plant. It is usually not the first or last method of wastewater treatment, but it is an important aspect of a multi-step purification process.
Advantages of MBBR
1: For Space Constraints, the Perfect Wastewater Solution
One of the most significant advantages of MBBR is that it does not necessitate a large amount of physical space. In fact, when compared to other biological water treatment systems, MBBR is noted for its minimal footprint. MBBR tank can treat the same volume of wastewater as a trickling filter or activated sludge tank while being a quarter of the size.
2: For inexperienced plant operators, it's simple to use
One of the other benefits of biofilm reactors is that they are simple to use. The science behind this procedure is complicated, but the procedure itself is simple. Another advantage of MBBRs that make them a preferred alternative for many industrial facilities is that they are low-maintenance. Monitoring and running pumps and blowers, as well as performing routine maintenance on screening, clarifier, influent equalisation, integrated control, and sludge handling systems, are all part of typical MBBR system maintenance.
3: Susceptible to Shock Loads
Another benefit of MBBR systems is that they are adaptable and can handle variable loads. This means they can successfully withstand shock loads.
4: With a short hydraulic retention time, it works quickly
Hydraulic retention time (HRT) is a metric that indicates how long it takes a water treatment system to adequately treat the influent. This can take a long time on some systems, implying that the procedure is slow. Less wastewater can be treated in a given length of time if the procedure is slower.
MBBR wastewater treatment disadvantages
1: Manual monitoring: One downside of MBBR systems is that they require manual monitoring. This is true of biological water treatment methods in general. Unlike other forms of water treatment, which can employ sensors to monitor the system's progress, a biological system, such as MBBR tank, requires an operator to take samples and test them on a regular basis to guarantee the bacteria on the carriers are still alive and well.
2: Skilled specialists: Another drawback of biological systems is that operators must be experts in the field of biological water treatment. This is required so that the media can be adequately analysed to confirm that it is still digesting the waste in the tank. Of course, as we've seen, operating the tank is a straightforward, mostly hands-off process.
3: Insects: Another disadvantage of dealing with biofilms is that some insects, such as sewage flies, mosquitoes, and red worms, will be drawn to it. This could result in a portion of the biofilm on the carriers being consumed by insects, jeopardising the system's functionality. Tanks built to keep these insects out can help treatment plants avoid this problem.
4: Escaping carriers: Despite the strainers in place to keep the carriers in, some customers have noted that the carriers can wash out of the system over time, even when there are no insects around. This could also be the result of a design defect in the tank itself.
There are considerably more benefits to adopting MBBR system with a properly built system than there are drawbacks!
