How MBBR Media Boosts Efficiency for Industrial Wastewater Treatment Projects

Industrial wastewater treatment will always present a difficulty, particularly to factories that face fluctuating water quality, effluent regulations, and higher operational costs. Numerous treatment plants struggle with increases in wastewater flows and production scheduling changes, this is the solution where MBBR (Moving Bed Biofilm Reactor) media comes in handy. MBBR media allows for the development of a high surface area in the treatment system to encourage microbial growth and in turn get rid of the pollutants from waste, without the requirement to enlarge the size of the treatment plant. Many factories, around the world, have begun using MBBR in their chemical manufacturing facilities and food processing plants, to help cut down costs and achieve much higher treatment rates.

What Is MBBR Technology?

The MBBR, or Moving Bed Biofilm Reactor, is a technology that uses specially manufactured, small pieces of plastic known as MBBR Biochip Media as habitat for helpful microorganisms that are part of a water treatment process. As they thrive, the microbes create a coating or “film” on the exterior surface of the plastic media. Wastewater is pumped through a tank where it flows around the media and microbes eat organic matter from the water and purify it. Air is blown through the tank or mechanical mixing of the contents occurs to continuously move the MBBR media through the wastewater and to continually expose all surfaces to the dirty water, increasing contact and efficiency of treatment. Whereas activated sludge systems maintain large portions of the treatment bacteria floating free in the water, in an MBR , these organisms are firmly attached to media and continue their work even when wastewater characteristics change. This allows an industrial company to upgrade its wastewater treatment plant without taking up additional physical space or construction of larger tank capacity. It is sometimes possible to put MBBR media in existing tanks to greatly increase their treatment capability, rather than building larger units. MBBR technology is being widely applied in industrial water treatment since MBBR is the cheapest and most efficient method that requires the least footprint to process high flows of water. If the treatment plant can cope with wastewater at most times of year except peak periods such as Summer time. The MBBR can achieve more microorganisms in the tanks to accommodate the peaks by increasing MBBR media amounts without too many tank size increases. MBBR media offers flexibility. Industrial wastewater may be subject to large swings in pollutants. MBBR system can provide better control for the fluctuating influence, compared with other common methods such as the activated sludge process. The stable and reliable performance MBBR is resistant to shock loads and can overcome variability in the industrial process. At the heart of the concept MBBR technology is a low-tech application of an advanced treatment idea.

Core Benefits of MBBR Carriers

The Moving Bed Biofilm Reactor process is all about the MBBR carriers. They primarily serve as a large protected surface for the growth of beneficial microorganisms and the creation of biofilms. Although they appear to be just plastic parts, their design can have a significant impact on the performance of a wastewater treatment system.The main advantage of the MBBR carriers is the huge surface area that is provided in a relatively small tank. Thousands of carriers are free to travel around the reactor which provides space for many more microbes than most traditional systems would allow. The more microorganisms, the more organic matter and other pollutants are removed.A further benefit is that of treatment stability. An industrial wastewater may vary from one hour to the other depending on the production schedule, the cleaning cycles or the raw materials used. The treatment systems may be stressed by these abrupt changes. The microorganisms do not float in the water, but are attached to the carriers, so there is a lower risk they will be washed out when the flow changes. This ensures continuous treatment performance in all the conditions.In addition, MBBR carriers can also reduce the demand for large treatment tanks. The biofilm can withstand high treatment rates, which means that facilities may often be able to increase capacity without increasing their plant footprint. This can be particularly beneficial for factories that are situated in locations where extra space is restricted or costly.Simply the maintenance needs are typically also less. Carriers are constantly moving, which prevents excessive amounts of biofilm growth. There is a natural erosion of old growth and a natural growth of new growth, which is a biological process. This will decrease operational issues and maintain smooth operations.This can include if a beverage factory increases in size and needs to cater for a higher wastewater flow. Instead of installing a new reactor they can simply introduce MBBR carriers to meet increased capacity and maximise system performance by adjusting carrier fill levels and aeration in the plant. These MBBR carriers prove to be an ideal technology for businesses seeking an upgrade in their water treatment systems due to various benefits such as increased cost-efficiency.

Common Application Scenarios

The ability to adapt to various wastewater properties and operating conditions makes the use of MBBR media applicable to various industrial wastewater treatment projects. In both new construction and upgrading of treatment facilities, using MBBR technology can result in better treatment performance without significant changes to the treatment facility structure.The food and beverage sector is one of the common applications. Food processing plant waste water may have large amounts of organic material, fats, oils and grease. Such pollutants are capable of straining wastewater treatment facilities. MBBR media has a large surface area for the microorganisms' growth; which can help to break down the organic wastes more efficiently. MBBR systems are utilized by numerous dairy factories, breweries and beverage factories to cope with seasonal changes in the wastewater load during the year.Another industry that has seen extensive use of MBBR technology is the pulp and paper industry. Paper mill effluents may contain significant amounts of biodegradable matter. Facilities can augment treatment capacity and enhance pollutant removal with MBBR media in biological treatment tanks without the need to construct additional reactors.MBBR systems work well in chemical manufacturing plants, too. Wastewater strength and flow rates may vary due to production schedules. This attached biofilm on the media contributes to a more stable biological process and enables treatment plants to better cope with these fluctuations.MBBR technology is often employed in the wastewater treatment system of textile factories. The wastewater from dyeing and finishing can be difficult to deal with because of fluctuations in organic loading and changing product demands. The healthy microbial population maintained by the use of MBBR media can operate even with fluctuation of operating conditions. Municipal wastewater facilities often need to expand capacity due to population increase and one way this can be achieved is by using MBBR media. Instead of building new facilities and incurring huge costs, plants can utilize their existing tanks by filling them with MBBR media and redesigning their flow.All these instances explain why MBBR technology has so many real-world applications, from all sorts of industrial companies to municipalities.
