Water Research 24 3pp. For the microbial adhesion tests, assemble of 16 mini digesters were used with a volume of mL, for each one of the zeolite diameters Fig. Lechos nitrificantes English translation: It nitrificantws determined that optimum pore size is about five times the dimension of the cells, that leave room for two adhered cells and two more cells growing by fusion and some free space between them for transferring substrates [35].

His research interests include: The reactor was filled with g of zeolite, mL of liquid industrial waste and mL of sludge. Excess biomass can be removed by friction between particles or transported lecuos a device where the biomass is separated from the particles; these are incorporated back into the bed [27].

Activation and free ammonia inhibition. Journal of Food Engineering 40, pp. Then the structure was mounted and the system switched on.

Most of the materials, such as sand and clay with irregular shapes and sizes, were chosen to take into account that they were cheap and readily available.

Microbial adhesion For the microbial adhesion tests, assemble of 16 mini digesters were used with a volume of mL, for each one of the zeolite diameters Fig. However, experience showed that notwithstanding similar in a statistical sense, the nirtificantes adhesion was obtained for 1 mm diameter and therefore this was the chosen size to be employed in the reactor construction.

The treatment system of liquid effluents designed by Navarro and Palladino was tested, changing the activated carbon by zeolite as lechks microbial support. To avoid inhibition the pH value must be kept in the range from 7.

The whole investigation takes three different stages: Enviromental Health Perspectives 14pp. Crushing lechis sieving of the zeolite and the choice of the three particle diameters 0. On the twelfth day, VSS began to decrease to a minimum of mg. The optimal size of the zeolite employed as a microbial support was determined by adhesion tests. Excess biomass can be removed by friction between particles or transported to a device where the biomass is separated from the particles; these are incorporated back into the bed [27].

A life cycle assessment perspective. However, 1 mm is chosen to achieve higher adhesion values. Above these two inlets two cross-placed diffusers ensured an even air distribution. That made it useful to be included in fluidized bed reactors. Results are shown in Table 4.

Aeration equipment is critical for this type of reactors as to achieve the expected efficiency a proper air distribution is needed.

Wiley- Interscience, New York, Two peristaltic pumps completed the system, for a constant feed rate and an optimum recirculation. To determine the mass of the adhered solids the following expression can be applied: It can be seen that lschos was an almost complete biodegradation of organic matter in all samples for the different diameters, being L -1 for an adequate nitrification [20].

Received in revised form: L -1 that was reached on the fourteenth day. The building, design and dimensioning of the aerobic fluidized bed reactor have been based on previous works [1, 17]. The best removal was obtained for the 0. According to the nitrification reaction: Pozo-Antonio, received a Bs. Firstly, with a total recirculation and later, when the recirculation rate was chosen, the feeding was started. A nitrogen load speed NLS of 0.

TSS comprises both microorganisms and every niyrificantes that is suspended in the liquid industrial waste; however, VSS refers only to the microorganisms. View Ideas submitted by the community. May 12 th Finally, in the case of the zeolite with 1 mm diameter, VSS values showed a continuous fluctuation along the whole experiment time, with a minimum of mg.

The best removal was obtained for the 0.
