To eliminate dissolved pollutants by biological means, ETE offers you the most innovative techniques for the biological (secondary) treatment of wastewater:
MBBR:
This involves removing organic matter by fluidized bed (Moving Bed Biofilm Reactor)
The technology used is a biological treatment in which the biomass is fixed and grows on mobile supports, under suitable conditions of agitation and oxidation. This system is defined as an evolution and improvement of the traditional activated sludge installation. In addition, it is an alternative for cases in which there is little space.
MBR :
In an MBR (Membrane Biological Reactor) purification plant, the technology of biological purification with activated sludge is combined with that of ultrafiltration of sludge through membranes which replace traditional secondary settling tanks.
The high filtration efficiency of the membranes allows the maintenance of sludge concentrations significantly higher than the values possible in traditional systems, thus increasing the purification capacity of the system by increasing the age of the sludge and therefore reducing the quantity. of sludge to be eliminated.
This system also makes it possible to comply with bacteriological limits without having to resort to disinfection treatments.
It is an alternative for cases in which there is little space.
SBR :
The SBR (Sequencing Batch Reactor) process is one of the most popular aerobic treatment technologies employed to treat municipal wastewater and wastewater from a variety of industries including refineries and petrochemical plants.
Activated sludge :
The activated sludge process is the most widespread in the world. Provided it is operated correctly, this process offers significant performance for the elimination of carbon, nitrogen or even phosphorus pollution through the free biomass in the ponds.
The elimination of pollution is done through biomass which corresponds to volatile suspended matter (VSM).
ETE offers you a complete range of equipment and instruments for the operation of all the aforementioned processes.
