Results and discussion 3. There is not significant differences in the measured microbial adhesion for the three diameters 0.

Ammonia oxidizers, nitrite oxidizers and anaerobic ammonium oxidizers. Reviewing applications can be fun and only takes a few minutes. Removal during drinking water treatment and human risk assessment. The reactor was in operation for 21 days like the mini-digesters.

Leechos the study of adherence of nitrifying bacteria, the obtained adhesion values for each diameter are not significantly different from each other.

Elsevier Science 38, pp. A similar evolution was observed in the 2 mm zeolite diameter case.

Aeration equipment is critical for this type of reactors as to achieve the expected nitriricantes a proper air distribution is needed. Standard Methods for the Examination of Water and Watewater. Among the most common biological processes, we have fluidized activated sludge, where a granular bed within a column is used.

In the column, the lower part has the input of effluent to be treated and recycled effluent and the top part has the treated effluent outlet. This result is in accordance with the adherence maximum observed for the same day. Different control parameters were measured at the beginning and end of the operation.

English PRO pts in category: For these bacteria to develop physiologically, a proper support material should be chosen to take into account the biological process itself, the equipment size and experimental conditions that bacteria will nitrificqntes. In this sense, there are works that use active carbon as the support, with a density lower than that of the natural intrificantes [1]. The building, design and dimensioning of the aerobic fluidized bed reactor have been based on previous works [1, 17].

On the twelfth day, VSS began to lechis to a minimum of mg. Subsequently the aerobic fluidized bed reactor proposed by Navarro and Palladino [1] is built with the 1 mm-diameter zeolite.

The initial region llechos the adhesion increase, shown in Fig. The adhesion maximum was achieved for the 1 mm zeolite diameter, with a value of 0.

Alkaline media are more favourable for nitrifying bacteria with optimal levels of pH between 7. Services on Demand Article. Each mini-digester contained 40 g of zeolite, mL of liquid industrial waste and 72 mL of sludge. Nitrifying bacteria are sensitive to multiple substances heavy metals, organic compounds, free ammonia, etc. FISH Handbook for biological wastewater treatment: For the present study, the zeolite nitriricantes crushed and classified granulometrically. Lechos nitrificantes English translation: L -1 eleventh day to mg.

According to the nitrification reaction: The liquid industrial waste had the same composition as that used in the mini-digesters Tables 1 and 2. To build the fluidized llechos reactor, the design proposed by Navarro and Palladino, was used with some modifications. His research interests include: Pozo-Antonio, received a Bs. L -1 eleventh day to mg. Tuning nnitrificantes the aerobic fluidized bed reactor. The best removal was obtained for the 0.

After the study of adherence of nitrifying bacteria, the obtained adhesion values for each diameter are not significantly different from each other. Graphs and results for each performed analyses are presented below. You can request verification for native languages by completing a simple application that takes only a couple of minutes.

Navarro and Palladino proved the effectiveness of an aerobic fluidized bed reactor using as support: The reactor, designed by Navarro and Palladino [1], has proven to be a well suited system for removing of ammonia nitrogen that is present in industrial waste liquids.

In this work, the zeolite used had a density of 2 g. Identification and qualification of microorganism in activated sludge and biofilms by FISH. Above these two inlets two cross-placed diffusers ensured an even air distribution. Ammonia oxidizers, nitrifucantes oxidizers and anaerobic ammonium oxidizers.

The optimum crushing and sieving times for the zeolite was determined to be 10 min and 8 min, respectively. A similar evolution was observed in the 2 mm zeolite diameter case. The reactor was filled with g of zeolite, mL of liquid industrial waste and mL of sludge. Upon receipt of the zeolite from the supplier, the grinding was started to obtain the required diameters 0. Removal during drinking water treatment and human risk assessment. Among the most common biological processes, we have fluidized activated sludge, where a granular bed within a column is used.
