A new Moving Bed Biofilm Reactor (MBBR) has been developed, where the biomass is attached to small plastic elements that move freely along with the water in the reactors. Several small biological/chemical wastewater treatment plants are now using the MBBR process. Official control samples have shown that these plants are very reliable. The average effluent concentrations from the plants surveyed, three retrofits and two originally designed with the MBBR process, were as low as 11 mg BOD7/l (∼9 mg BOD5/l), 11 mg SS/l and 0.26 mg total P/l. Approximately 2 man hours per week were needed for operation of a plant originally designed with the MBBR process.

In 1988 the State Pollution Control Authority in Norway made recommendations regarding process designs for small wastewater treatment plants. Amongst these were recommendations for biological/chemical plants where biofilm reactors were used in combination with pretreatment in large septic tanks and chemical post treatment. At the same time the socalled “moving bed biofilm reactor” (MBBR) was developed by a Norwegian company. In this paper, experiences from a small wastewater treatment plant, based on the MBBR and on the recommendations mentioned, will be presented.

Wastewaters from three integrated newsprint mills have been treated in a pilot plant Moving Bed Biofilm Reactor (MBBR). In the MBBR the biomass adheres to small plastic elements which move freely along with the water in the reactor. A reduction of 65-75% for COD and 85-95% for BOD was obtained at HRT of 4-5 hours. By prolonging the HRT the removal efficiencies of COD and BOD increased to about 80% and 96%, respectively. With a subsequent chemical precipitation a removal efficiency of COD up to 95% was achieved. The amount of chemicals needed for precipitation of the biologically treated wastewater was only a quarter to a third of that needed for chemical treatment of the untreated wastewater. The results showed the MBBR process to be competitive with conventional biological treatment systems and that treatment objectives can be met at short HRTs.

A novel moving bed biofilm reactor has been developed, where the biofilm grows on small, free floating plastic elements with a large surface area and a density slightly less than 1.0 g/cm3. The specific biofilm surface area can be regulated as required, up to a maximum of approximately 400 m2/m3. The ability to remove organic matter from concentrated industrial effluents was tested in an aerobic pilot-plant with two moving bed biofilm reactors in series and a specific biofilm surface area of 276 m2/m3. Treating dairy wastewater, the pilot-plant showed 85% and 60% COD removal at volumetric organic loading rates of 500 g COD/m3h and 900 g COD/m3h respectively. Based on the test results, the moving bed biofilm reactors should be very suitable for treatment of food industry effluents.

The effect of tetracycline (TC) on nitrogen removal in wastewater treatment plants has become a new problem. This study investigated the effects of TC on nitrogen removal using a Moving Bed Biofilm Reactor system. The results showed that there was no significant effect on nitrogen removal performance when the concentration of TC was 5 mg/L, and that the total nitrogen (TN) removal efficiency could reach 75–77%. However, when the concentration of TC increased to 10 mg/L, the denitrification performance was affected and the TN removal efficiency decreased to 58%. The abundance of denitrifying bacteria such as those in the genus Thauera decreased, and TC-resistant bacteria gradually became dominant. At a TC concentration of 10 mg/L, there were also increases and decreases, respectively, in the abundance of resistance and denitrification functional genes. The inhibitory effect of TC on denitrification was achieved mainly by the inhibition of nitrite-reducing bacteria.

The paper presents the comparison between the traditional activated sludge system (AS) and a hybrid moving bed biofilm reactor (HMBBR). In particular, an experimental campaign has been carried out at the WWTP in Palermo (Italy), on a pilot plant consisting of two pre-anoxic schemes. The aerated tank of the HMBBR line was filled with suspended carriers (AnoxKaldnes™ K1), with a 30% filling ratio. The hydraulic load of the HMBBR line was increased up to two times the AS one. Further, in order to distinguish the additional contribution of the attached biomass for the HMBBR system, in the two lines the Mixed Liquor Suspended Solids (MLSS) was maintained as equal as possible. The monitoring period lasted three months during which several parameters were monitored. The obtained results showed a good treatment ability of the HMBBR system, referring to the organic matter removal as well as to the ammonium removal. In particular, in spite of the increase of the hydraulic load for the HMBBR line, the two systems showed a similar performance in terms of both organic and nitrogen removal. The results demonstrate the higher treatment capacity of the HMBBR addressing such system as an effective technology for the upgrading of overloaded wastewater treatment plants.

Abstrak.  Penelitian ini bertujuan untuk mengetahui efektivitas pengolahan air lindi (leachate) dengan proses aerob menggunakan aplikasi reaktor biofilm dan reaktor tanpa biofilm untuk mengurangi bahan pencemar pada lindi. Penimbunan sampah yang dilakukan setiap harinya di tempat pembuangan akhir (TPA) dapat menimbulkan masalah bagi lingkungan sekitarnya, dengan terbentuknya air lindi (leachate). Lindi yang terinfiltrasi akan mencemari air tanah. Pengolahan leachate sampah dilakukan secara fisika, kimia atau biologi tergantung pada karakteristik lindi. Kurangnya kandungan oksigen terlarut akan menghambat proses biodegradasi sehingga kandungan zat organik lindi akan meningkatmaka dilakukan uji coba pengolahan air lindi dengan teknologi aerasi menggunakan biofilm atau sistem pertumbuhan melekat MBBR untuk menurunkan kandungan bahan pencemar. Pengolahan dilakukan selama 10 hari olah menggunakan sistem kontinu, membandingkan reaktor tanpa biofilm (kontrol), reaktor MBBR menggunakan media k1 (kaldness) sebagai filter dan tempat melekatnya mikroorganisme serta reaktor MBBR  menggunakan arang  tempurung kelapa sebagai absorban. Volume yang digunakan 5 liter lindi untuk setiap reaktor. Dari pengolahan yang dilakukan diperoleh penurunan BOD adalah  64%, 73%, dan 75%; COD adalah mengalami kenaikan 8%, 14,3%, dan 35,8%; TKN adalah 44,44%, 56,73%, dan 75,7%, Fe adalah 9,041mg/l (influent); 8,033 mg/l; 9,0543 mg/l dan 5,053 mg/l.The Effect of Application Moving Bed Biofilm Reactor (MBBR) To Leachate Wastewater Treatment Aerobically To Water QualityAbstract. This study aims to determine the effectiveness of leachate with aerobic processes using biofilm reactors and reactors without biofilms to reduce pollutants in leachate. The landfill that is carried out every day in the landfill (TPA) can cause problems for the surrounding environment, with the formation of leachate (leachate). Infiltrated leachate will contaminate ground water. Processing of waste leachate is done in physics, chemistry or biology depending on leachate characteristics. Lack of dissolved oxygen will inhibit the biodegradation process so that the content of leachate organic matter will increase, then a trial of leachate treatment with aeration technology is carried out using a biofilm or MBBR's inherent growth system to reduce the pollutant content. Processing was carried out for 10 days using a continuous system, comparing the reactor without biofilm (control), the MBBR reactor using k1 (kaldness) as a filter and the attachment of microorganisms and the MBBR reactor using coconut shell charcoal as absorbent. The volume used is 5 liters of leachate for each reactor. From the processing carried out obtained a decrease in BOD is 64%, 73%, and 75%; COD has increase by8%, 14.3%, and 35.8%; TKN is 44.44%, 56.73%, and 75.7%, Fe is 9.041mg/l (influent); 8.033 mg / l; 9.0543 mg /l and 5.053 mg /l.

Abstract Detergents are considered one of the important pollutants in hospital wastewater. Achieving efficient and bio-friendly methods for the removal of these pollutants is considered as a concern for environmental researchers. This study aims at studying the efficiency of a moving bed biofilm reactor (MBBR) system for removing linear alkyl benzene sulfonate (LAS) from hospital wastewater with utilization of response surface methodology (RSM). The present study was carried out on a reactor with continuous hydraulic flow using media k1 at pilot scale to remove detergent from hospital wastewater. The effect of independent variables including contact time, percentage of media filling and mixed liquor suspended solids (MLSS) concentration of 1000-3000 mg/l on the system efficiency were assessed. Methylene blue active substances (MBAS) and chemical oxygen demand (COD) 750-850 mg/l were used by closed laboratory method in order to measure the concentration of LAS. The results revealed that the removal efficiency of LAS detergent and COD using media k1, retention time of 24 hours, and MLSS concentration of around 3,000 mg/l were 92.3 and 95.8%, respectively. The results showed that the MBBR system as a bio-friendly compatible method has high efficiency in removing detergents from hospital wastewater and can achieve standard output effluent in acceptable time.
