| Abstract | Summary form only given. This paper presents a study of waste water treatment by multielectrode corona reactor. A mixture of gas and polluted water aerosol flows through the 1.2-m length reactor. The flow rate is 200 l/h. A nanosecond solid state power supply (45 kV, 60 ns, up to 1 kHz) was used as a driver for the corona discharge. The cleaning experiments had carried out with a simulant and industrial waste water. Authors have investigated a simulant PEG300 to demonstrate the corona reactor in cracking of long chain organic molecules into smaller ones. As a result of the simulant treatment the ratio between the biological oxygen demand (BOD) to the chemical oxygen demand (COD) increased from below 0.01 to almost 0.5. The reactor has been used also for a treatment of a brewery effluent. The following conclusions were made: i. Treatment in the aerosol reactor removes up to 50% of the recalcitrant COD in the effluent; ii. Ammonia nitrogen is oxidized to nitrate nitrogen during treatment in the reactor; iii. The effect on phosphates is limited. Tests with concentrated waste water of a packaging recycling company have demonstrated the improvement of biodegradability. These tests showed an increase in COD removal to up to 60%, meaning that after the treatment in the corona aerosol reactor the HOD/COD ratio had increased. Thus, the aerosol corona reactor technology offers good opportunities to treat waste water that are not likely to be treated biologically at the moment. |

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.
