| Abstract | Afin de garantir la sécurisation des tours aéroréfrigérantes, l’utilisation de traitements chimiques reste à ce jour la solution la plus couramment utilisée. La gestion du risque de prolifération des légionelles repose non seulement sur le choix cohérent des traitements mis en œuvre, mais également sur la surveillance de leur efficacité. Une stratégie biocide reposant sur l’utilisation conjointe d’un biocide oxydant (brome, chlore) injecté en continu, et d’un biocide organique (THPS ou isothiazolone) injecté en choc a donc été déployée par le groupe Veolia environnement. Ces produits ont fait l’objet d’essais laboratoire à Anjou Recherche et de retour d’expérience terrain permettant de valider leur efficacité (cinétique d’inactivation des légionelles) avant leur déploiement. Ces expérimentations ont permis d’alimenter le référentiel VE rédigé par les experts du groupe. Ce guide décrit en effet avec précisions les conditions opérationnelles de cette stratégie. Le retour d’expérience réalisé à l’aide des analyses méthodiques des risques d’installations auditées par un bureau d’étude a permis de mettre en évidence une bonne efficacité de la stratégie biocide VE. De plus, dès lors que sa mise en œuvre est réalisée dans les règles de l’art, cette stratégie permet une sécurisation des installations sujettes à la flore interférente. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
