| Abstract | A novel combined autotrophic nitritation and bioelectrochemical-sulfur denitrification (CANBSD) process was developed for treatment of synthetic ammonium-rich wastewater with low carbon/nitrogen ratio. Total nitrogen removal of the CANBSD was higher than 95 %, the effluent $SO_{4}^{2−}$ was lower than $1280 mg L^{−1},$ and the maximum nitrogen volumetric loading rate was $1.2 kg m^{−3} day^{−1}$ when (1) the influent $NH_{4}^{+}-N$ was lower than $1008 mg L^{−1},$ (2) hydraulic retention time was between 3.7 and 32 h, (3) the DO was between 0.5 and $1.2 mg L^{−1},$ (4) the pH was between 7.5 and 8.2, and (5) the temperature was between 28 and 30 °C. Both the $NH_{4}^{+}-N$ removal and conversion to $NO_{2}^{−}-N$ in the nitritation membrane reactor (NMBR) were maintained at about 50 %, and the residual $NH_{4}^{+}-N$ and accumulated $NO_{2}^{−}-N$ were subsequently treated in the bioelectrochemical-sulfur three-dimensional denitrification reactor. The CANBSD energy consumption was 0.13 and $3.4 kWh m^{−3},$ respectively, for influent $NH_{4}^{+}-N$ of 100 and $1000 mg L^{−1}.$ The energy consumption of CANBSD was close to that of partial nitritation-ANNMMOX. |

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.
