Mobile Sewage Treatment Plant MBCR

ItN Nanovation’s MBCR-Filtration Container is a mobile, decentralized system for treating municipal or similarly polluted wastewater. It combines a biological treatment (MBBR technology) with a subsequent microfiltration by ceramic flat membranes.

One of the MBCR Container Plant is installed in bypass at the WWTP EVS-Burbach, just 8 km away from the main premises of ItN Nanovation AG in Saarbrücken.

The main objective of this project is to test and optimise the total performance of the MBCR Filtration Container, based in the know-how of the company, to achieve an excellent quality of the produced permeate.

The plant was installed with the corresponding water and electrical connections on the 8th August 2011. Filtration was started up on the 19th August 2011. After letting the biology settling for two weeks, the weekly analysis and testing of the plant started at the beginning of September 2011.

 

The MBCR plant is developed patented and produced by ItN Nanovation and offers a robust and reliable wastewater cleaning process as well as a safe removal of all bacteria and suspended solids.

The plant design contains a 3-zone biological treatment tank, a settling zone, the filtration tank with 64 m² of ceramic flat member, permeate tank for backwash and cleaning and the machinery room.

Bacteria for the wastewater cleaning grow on a so-called moving bed in the 3-zone bioreactor, which is mixed and provided with oxygen by aeration. The moving bed consists of a special carrier material with a surface of up to 3,000m per cubic meter of carrier material. Every bio zone can run under oxic or unoxic conditions to force Ammonia or Nitrate/Nitrite removal.

ItN Nanovation’s asymmetric flat membranes combine for the first time the advantages of a robust ceramic support material with those of a submerged filtration process. The properties of the membrane are further improved by an additional nanoceramic coating, allowing the adjustment of pore sizes according to the specific application.

State-of-the-art monitoring and control technology with PLC and remote access ensures a safe, trouble-free and continuous operation of the system. The MBCR Filtration Container has been developed for a reliable, efficient and cost-saving wastewater treatment and reuse while requiring low operating and maintenance costs and can be used in connection with existing systems or as a stand-alone solution. The plug-and-play connections ensure a fast and trouble-free commissioning.

The MBCR Filtration container installed at the Burbach sewage treatment plant provides an efficient R&D test field, enabling continuous improvement of the process as well as of the hard- and software.

Upon request, ItN Nanovation offers guided visits to the location with a presentation of the technology. Please be advised that it is necessary to arrange an appointment for this visit four weeks prior to the desired date.

Continuing the successful cooperation with EVS Saarland, ItN will remain operator of the plant, thus ensuring further and ongoing improvement of our technologies.
