Compounds with highly fluorescent properties having extended<br />
π-conjugation continues to arouse interest because of their<br />
fascinating applications such as sensors and biosensors,<br />
electroluminescent materials, lasers, and other optoelectronic<br />
devices.<br />
New N-bridgehead heterocyclic compounds with pyrrolopyridazine<br />
moiety represents a class with interesting optical<br />
properties, due to their containing a π-excessive pyrrole and a πdeficient<br />
diazine ring with one bridgehead nitrogen.<br />
The aim of this work was to synthetise new isoindolo-1,2-diazine<br />
compounds with a pyrrolo-diazinic skeleton, using a general and<br />
straightforward strategy (quaternization and cycloaddition<br />
reactions) under classical conditions and nonconventional<br />
methods.<br />
The structure of compounds was proved by spectral analysis (IR,<br />
MS, NMR) and X-ray diffraction.<br />

Description<br />
Moving bed systems comprise all biofilm processes with<br />
continuously moving media, maintained by high air, water<br />
velocity or mechanical stirring. Small parts made of special<br />
materials with density close to the density of the water, are<br />
immersed in the bioreactors. This type of support is most effective<br />
because it does not clog and it does not require additional energy<br />
consumption. The biofilm carriers are kept in suspension and even<br />
mixed with the help of air bubbles generated by the aeration<br />
system.<br />
The main purpose of this study is to determine the concentration<br />
of dissolved oxygen (DO) using mathematical modeling and<br />
numerical simulations. In the second stage, several experiments<br />
are realized and the aeration system efficiency is determined.<br />
