| Abstract | Emitter clogging has become one of the main restrictions in the development of drip irrigation with reclaimed water. Numerous studies have found that emitter clogging is closely related to the formation and growth of biofilms attached within the emitter wall, raising the question of how to effectively control the formation of biofilms, which is the key to solving emitter clogging. Lateral flushing could promote the rapid shedding of biofilms and wash the irrigation system by increasing the hydraulic shear force within the laterals; this would reduce the frequent shedding of biofilms from the lateral walls into the emitter during the irrigation operation and the clogging of the emitter. Therefore, we conducted an in situ drip irrigation experiment with reclaimed water in a sewage treatment plant under three conditions of lateral flushing frequency (triweekly, biweekly, and weekly), and the dynamic changes in emitter clogging and biofilm components were studied. We found that lateral flushing can effectively slow down emitter clogging in a reclaimed water drip irrigation system. The values for the discharge ratio variation and coefficient of uniformity were the highest, and those for solid particles and phospholipid fatty acids were the lowest for the biweekly lateral flushing frequency. However, lateral flushing failed to completely solve the emitter clogging problem, and some additional measures must be combined with this process to control emitter clogging problems. |

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.
