The technology of MBBR systems (Moving Bed Biofilm Reactors) was created as an alternative with biomedia for water treatment and consists of the introduction of small plastic rings (biomedia/biofilters) in aeration tanks, which, in contact with the effluent, allow the fixation of microorganisms inside, which oxidize and treat the organic load.
According to the director of Ucelo do Brasil, Bruno Pavani, basic sanitation is a key issue today and there is a growing demand to optimize wastewater treatment, even improving the quality of life of the population. “In this sense, we started to follow the trends of this market and we focused on the research of alternatives with the highest technology and thus we started the development of this product, biomedia for water treatment”, he explained.
With a high technology industrial park, the company develops the biomedia for water treatment according to the customer's needs, always aiming at greater chemical and physical resistance of the product and thus ensuring more efficiency in biomedia for water treatment.
What is the MBBR system (biomedia for water treatment)?
The system of MBBR-type sewage treatment (biomedia for water treatment) was developed in Norway in the 1980s, through a partnership between the company Kaldnes Miljǿteknologi AS (KMT), a specialist in the treatment of domestic and industrial effluents, and the SINTEF Research Institute (Rusten et al, 2000).
Basically, the process of MBBR(biomedia for water treatment) is a technology adapted to activated sludge systems, through the introduction of small pieces of biomedia for water treatment inside the aeration tank, which act as a support medium for the development of the biofilm, kept in constant circulation and mixing either due to the introduction of diffused air or due to the existence of mechanized agitators; there is no need to recirculate the sludge (WEF, MOP no.35, 2010; Minegatti, 2008; Rusten et al, 2000; Ødegaard et al. 1994).

In this way, the MBBR system (biomedia for water treatment) incorporates the best characteristics of the growth processes of biomass in suspension and adhered biomass, giving the process a considerable contribution of solids in suspension, providing an increase in the population of microorganisms active in sewage purification, thus allowing the treatment of carbonaceous and nitrogenous organic loads higher when compared to the activated sludge system.
inside the aeration tank for MBBR/IFAS processes (biomedia for water treatment), the filling material biomedia for water treatment it is kept in continuous movement by the mixture promoted by the aeration system, presenting high mobility and, consequently, exposure and contact with the liquid mass. It is thus a hybrid biological reactor, in which microorganisms are kept suspended in the medium as well as adhered to the support medium.
