Crushing and sieve analysis. Therefore, the power of the diffusion pump was enough to overcome the gravitational forces acting on the particles to achieve the fluidization of the system entirely.

Crushing and sieve analysis Upon receipt of the zeolite from the supplier, the grinding was started to obtain the required diameters 0. United State of America, pp. In most countries, there are laws and legal regulations lehcos limits for the concentration of ammoniacal nitrogen in the wastewater nitrificanted such as the Biological Oxygen Demand BOD and Chemical Oxygen Demand COD [17]. L -1 due to the above mentioned cryptic growth stage. FISH Handbook for biological wastewater treatment: The COD experimented an important decrease from to mg.

Results are shown in Table 4. L -1 was observed the ninth day.

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. According to the nitrification reaction: You have native languages that can be verified You can request verification for native languages by completing a simple nitrigicantes that takes only a couple of minutes.


After this initial time zeolite and liquid samples were taken every two or three days. Different control parameters were measured at the beginning and end of the operation.

L -1 eleventh day to mg. This result is in accordance with the adherence maximum observed for the same day. Prior to their employment in the mini-reactors, they were subjected to the following characterization Table 3: It was found that ammonium produces the inhibition of Nitrobacter [31].

This presented an inlet flow of 1. Crushing and sieve analysis As shown in Table 5 nitrificantfs, after crushing and sieving enough zeolite for each of the expected sizes 0. Materials and methods 2. L -1 is due to errors in the data collection and sampling. In this work, we determine the optimal zeolite size for the correct physiological development of nitrifying bacteria to be used in a subsequent aerobic fluidized bed reactor to remove ammonia nitrogen existing in industrial wastewater.

In this work, the zeolite used had a density of 2 g. To ensure a proper implementation of the fluidized bed aerobic reactor a number of biological, chemical and physical parameters such as temperature, nitrififantes, microbial support, volume, feeding rate, retention time, and the reactor dimensions and configuration must be taken into account [28].

First modification related to the employed microbial support [1]. Then the structure was mounted and the system switched on.

In the Table 6the parameters which were measured after 21 days of operation. In nitrificcantes to the experience, a constant control of the reactor is required to achieve a good oxygenation.

The final value corresponding to a drastic increase till mg. In this work, the zeolite used had a density of 2 g. You can request verification for native languages by completing a simple application that takes only a couple of minutes.

However, experience showed that notwithstanding similar in a statistical sense, the best adhesion was obtained for 1 mm diameter and therefore this was the chosen size to be employed in the reactor construction. After the study of adherence of nitrifying bacteria, the obtained adhesion values for each diameter are not significantly different from each other.

A nitrogen load speed NLS of 0. Identification and qualification of microorganism in activated sludge and biofilms by FISH.
