Theme 2 - Evaluating
Generally, the conventional method was used for water assessment. This type of method is based essentially on the count of viable and culturable bacteria on usual media. Despite its importance, this assessment technique requires several days and the results can underestimate the real bacterial quality of treated water. Indeed, after water disinfection by physical or chemical processes, many species of bacteria can enter in viable but non-culturable (VBNC) state as an adaptation strategy to survive and to persist in a hostile environment. This type of bacteria can cause false-negative results and, as a consequence, can pose a significant and potential health risk (mainly for pathogenic bacteria). Accordingly, the monitoring of bacterial water quality based only on the classic methods is not sufficient to monitor and to detect water disinfection trouble on real or near real-time. To overcome this problem, its important to develop rapid, sensitive, non-culture, reliable and low-cost methods. These methods can allow the establishment of an action plan to react rapidly and effectively; to correct the malfunction of the disinfection step.
The Water Researches and Technologies Center of BorjCedria(WRTC) was established on February the 16th, 2005bythe Decree No.337/2005, it's a public establishment with, administrative nature, a legal personality and financial autonomy.
The Center is responsible for:
Carry out research on the various laboratories.
Participate in the development of scientific research and technology especially in the field of Undertake, at the request of ministries, national institutions, establishments and public and private enterprises in the framework of conventions established for this purpose, any research or experimentation expertise.
Conduct scientific research projects and developments.
Contribute to the development of science and technology in the field of water.
Contribute to the training of researchers.
Exploit the results of research in the field of water.
