| Abstract | A novel integrated UV-biofilter system using UV reactor as the pretreatment process was setup to treat high concentration of gaseous volatile organic compounds (VOCs). Another control biofilter without the UV pretreatment was also established to compare the performance of the two systems. Chlorobenzene was selected as a model compound. The two systems were operated in parallel under different inlet chlorobenzene concentrations (500, 1000, 1600, mg · m$^{−3}$). The experimental results indicate that the integrated system could eliminate chlorobenzene completely (100% removal efficiency) at the inlet concentration of 500 mg · m$^{−3}$, whereas only 60% removal efficiency was achieved for the control biofilter. Also the elimination capacity for the organic carbon of the integrated system was much higher than that of the control biofilter. On the basis of intermediates analysis by Ion Chromatography and Gas Chromatography-Mass Spectrometry, the UV pretreatment has been proven to be able to enhance the performance of the following biofilter by transferring the recalcitrant target to some more biodegradable and soluble organic products (such as formic acid and chlorophenol). Furthermore, the produced ozone, a harmful by-product from UV photo-degradation, could be easily eliminated by the following biofiltration process. |

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.
