Nature-Based Wastewater Treatment Systems

Adarsh Kumar is engaged in understanding the role and mechanism of bacterial ligninolytic enzymes (Laccase, Lignin peroxidase, and Manganese peroxidase) in the degradation and detoxification of residual organic and inorganic pollutants from industrial wastewater and value-added product recovery. He has qualified National Eligibility Test (NET) for lectureship in 2016. Currently, he is working with the District Environment Committee, Pilibhit, UP, framed by the Department of Environment, Forest and Climate Change, Government of Uttar Pradesh, India and awarded as a certified Miyawaki Plantation Professional. He has published many scientific original research papers, book chapters, and proceedings magazines, as popular science articles in several peer-reviewed international and national journals. He has presented some papers at national and international conferences in his field. He has also served as a potential reviewer for various scientific journals in his research areas. He is a life member of the Association of Microbiologists of India (AMI), Indian Science Congress Association (ISCA), and International Society of Environmental Relationship and Sustainability (ISERS), India. Saroj Kumar is currently working on nature-based wastewater treatment technologies for sustainable wastewater management and resource recovery for the circular economy. The major research focus of Dr. Kumar is on the management of water resources, especially through constructed wetlands technology. He has qualified National Eligibility Test (NET) for lectureship and Junior Research Fellowship in the years 2015 and 2016 in Environmental Science, conducted by the Indian Council of Agricultural Research (ICAR, India) and University Grants Commission (UGC, India) respectively. He has published several articles in high-impact, peer-reviewed international journals, chapters with international publishers, and popular science articles in magazines. He has also presented several papers at national and international conferences, events, and training programs in India. He is an editorial member of the Journal of Plant published by Science Publishing Group, USA, and acts as a reviewer in several international journals. He is an active member of the Indian Science Congress Association (ISCA) and the Institute of Scholars (InSc), India. Dr. Kumar also received the Research Excellence Award from the Institute of Scholars India. Currently, he is working with the District Environment Committee, Lakhimpur Kheri, under the administrative supervision of the Department of Environment, Forest and Climate Change, Government of Uttar Pradesh, India. He is recognized as a certified Miyawaki Plantation Professional in India.Sheel Ratna is currently working on wastewater treatment through bacterial-assisted constructed wetlands, adsorbent columns, and the production of value-added products utilizing wastewater as a substrate. He has qualified for several national-level exams such as ICAR-NET (2016) in Environmental Science, ICAR-NET (2017) in Agricultural Microbiology, UGC-NET/JRF (2017) in Environmental Science and GATE-(2019) in Life Science. He has published several research articles in peer-reviewed international journals with high repute, and chapters with international publishers. He has also presented several papers at national and international conferences, and events in India. He is an active member of the Indian Science Congress Association (ISCA) and the Association of Microbiologists (AMI) of India.
