Lechos nitrificantes | Spanish to English | Architecture

Adhesion tests were performed with the zeolite extracted from each mini-reactor. After the study of adherence of nitrifying bacteria, the obtained adhesion values for each niyrificantes are not significantly different from each other. References nnitrificantes Navarro, A. In response to the experience, a constant control of the reactor is required to achieve a good oxygenation.

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.

Removal during nitrfiicantes water treatment and human risk assessment. To build the fluidized bed reactor, the design proposed by Navarro and Palladino, was used with some modifications. Materials and methods 2.

L -1 was observed the ninth day. L -1 due to the above mentioned cryptic growth stage.

A life cycle assessment perspective. First modification related to the employed microbial support [1].

Activation and free ammonia inhibition. Mini-digesters were grouped in pairs, for each zeolite diameter. That made it useful to be included in fluidized bed reactors. As they affirmed, with higher COD Tentthe degradation efficiency is better.

Conclusions The lrchos crushing and sieving times for the zeolite was determined to be 10 min and 8 min, respectively. Most assays were done three times in order to have well defined average values.

L -1 thirteenth day was observed. Int J Life Cycle Assess.

The initial region of the adhesion increase, shown in Fig. 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. Peer comments on this answer and responses from the answerer agree. The whole investigation takes three different stages: Journal of Food Engineering 40, pp. It was found that ammonium nitriifcantes the inhibition of Nitrobacter [31].

In these systems, feed and recycle rates must sustain the fluidization of the bed [1,21] and degradation of organic matter by micro-organisms on the surface of the particles [1, ]. You can request verification for native languages by completing a simple application that takes only a couple of minutes. Prior to their employment in the mini-reactors, they were subjected to the following characterization Table 3: It can be seen that there was an almost complete biodegradation of organic matter in all samples for the different diameters, being This was loaded onto the column to achieve a fixed bed height of 15 cm.

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.

Further, humans severely alter the nitrogen cycle by increasing its availability in many regions of the planet as a result of point and diffuse sources of pollution.

How to cite this article. Navarro and Palladino proved the effectiveness of an aerobic fluidized bed reactor using as support: Results are shown in Table 4. Below the plate there were feeding inlets for the effluent to be treated and recycling. After this initial time zeolite and liquid samples were taken every two or three days.
