The market leading AnoxKaldnes™ MBBR (Moving Bed Biofilm Reactor) technology by Veolia is based on the biofilm principle and is used for biological wastewater treatment. Microorganisms grow on small specially designed plastic carriers that are kept suspended in a reactor. Solutions based on AnoxKaldnes™ MBBR technology by Veolia water technologies offer numerous benefits, such as robust biofilm, flexible reactor design, easy upgrade of existing plants, easy to operate and control, no sludge return needed in most applications, low load on particle separation stage. The Veolia water technology utilizes the advantages of both activated sludge and other biofilm systems (e.g. biofilters, biorotors etc.) without being restrained by their disadvantages. The carriers are designed to provide a large protected surface area for the biofilm to grow and optimal conditions for the bacteria culture when the carriers are suspended in water.
During this times as the Chinese New Year comes, clean drinking water is needed for the festivities because every Chinese person needs to have a clean and rich body while he enters the first day of the year. There would be billions of people that needs clean water who are celebrating the Chinese New Year all around the globe especially in East Asia and south East Asia who will be cooking and drinking at the said occasion. Recognized as a world leader in environmental treatment, AnoxKaldnes operates as a supplier of technology and equipment for wastewater and drinking water treatment. Just adding some plastic, moulded into a peculiar shape, to a wastewater basin and seeing what happens is a quick way to failure. Besides the specially designed carriers, you need knowledge of microbiology, hydraulics and engineering to design a long-term solution.
There is continuous, ongoing, research and development of AnoxKaldnes™ MBBR technology. Existing processes are improved and processes for new applications are continuously invented. A broad range of different carrier types has been developed in order to target the specific needs of different projects. The over 700 installations spread all over the world show many have discovered the benefits with a biofilm process based on AnoxKaldnes™ MBBR technology. The AnoxKaldnes™ MBBR technology is an ideal solution for treatment of potable water whenever there is a need for removal of biologically transformable pollutants, such as NH4+, NO3- or organic compounds. At the Nam Du Water Treatment plant, Hanoi, Vietnam, AnoxKaldnes MBBR is used to reduce the high, naturally occurring, ammonium level in the deep well water.
Wastewaters originating from industries in the food and beverage market are known to be easily degradable and non-toxic. Food production facilities often present other challenges, for example, seasonal production variations with seasonal variations of wastewater loads. The AnoxKaldnes MBBR is a robust process that can easily handle these variations. In some cases, the industry only needs a simple pre-treatment of their wastewater before it is discharged to the sewer system for further treatment at the municipal wastewater treatment plant. The solution is, an easy to operate single AnoxKaldnes MBBR reactor without sludge removal that provides a compact, robust and simple treatment system for removing organic matter. In other cases, the wastewater will be discharged directly to a recipient. This normally requires not only a high removal of organic matter, but also sludge separation. Downstream of an AnoxKaldnes MBBR system, our Veolia Water Technologies partners can provide a sludge separation step.
