Speech Title: SHEFROL: A novel bioreactor for rapid and inexpensive treatment of wastewater
Abstract: The SHEFROL technology is particularly suited to the treatment of sewage (greywater) which is the most voluminous and problematic wastewater in all developing countries, including India and China. As of now over 75% of it is discharge untreated, playing havoc with rivers, lakes and ponds. It is also believed to be the biggest source of most water-borne diseases.
The SHEFROL technology revolves round the trademarked SHEFROL® suit of reactors developed earlier by Prof S. A. Abbasi and his co-workers at the Centre for Pollution Control and Environmental Engineering, Pondicherry University. In 2018 a patent was granted to it after the technology had been extensively field-tested on several pilot plants set up within Pondicherry University, in the villages of Puducherry, and a resort at Madurai. At present plants based on this technology are being commissioned in the towns of the state of Utter Pradesh, India.
The unique feature of this technology is that it is over 6 times less expensive than the next cheapest conventional technology while being as effective and efficient as the best. It is also ‘self propogating’, requiring very low energy inputs, material inputs and maintenance effort. Besides receiving a patent, Prof Abbasi and co-workers have also published 17 research papers in indexed international journals on the various scientific and technological aspects of the SHEFROL® technology.
The core of the technology is the SHEFROL reactor comprising of channels in which short-statured terrestrial, amphibious, or aquatic weeds are packed to capacity. The dimensions of the channels have been set by extensive modelling and optimization. Wastewater is made to flow though the channels at a depth adequate to cover the plant roots. Hence the acronym SHEFROL® to express the “sheet-flow root level” Hydrology of these reactors. The unique design and operation of SHEFROL® enables it to achieve removal of numerous pollutants in a single step, or ‘pot’, in contrast to conventional technologies which need several different units in series. Based on systematic screening of commonly available short-statured weeds the inventors have identified a suit of 20 weeds which are easily and freely available throughout India and of which one or more can be used in each SHEFROL system. After stacking in SHEFROL® channels these weeds gorw and reproduce as they treat the wastewater. This makes the system self-propagating as no stirring, fertilization, aeration etc are involved. For the same reason the system has negligible operation/maintenance cost or depreciation.
Biography: Prof S. A. Abbasi has been a full university professor and centre director during 1987-2015 and is an Emeritus Professor since then. Prior to it he was Head-in-charge of the Water Quality & Environment Division at the Centre for Water Resources, Kozhikode (1979-87), and a Visiting-cum-adjunct Professor at California State University (1984-1987). He has also been a Visiting Professor at the universities of Minnesota, Florida, California−Berkeley, Malaya and Al-Ahsa.
With 43 books, over 400 papers in indexed journals, 12 patents, close to 16,000 citations and a Hirsch Index currently at 70, Prof Abbasi is among the world’s foremost experts in the fields of process safety and environmental engineering. In the recent Stanford University study, he was ranked among the world’s top 0.5% scientists, and among the top 100 Indian scientists, independent of the area of specialisation [https://www.thehindu.com/news/cities/puducherry/pondicherry-university-professor-felicitated/article33349572.ece] .
Among numerous coveted honours and awards received by him are the National Design Award in Environmental Engineering, the IPCL award for Safety and Hazard Management in Petroleum Industries, the National Hydrology Award, the International Desalination Association’s prize, and fellowships of the National Academy of Sciences and the Indian Institute of Chemical Engineers. Prof Abbasi is also well-known for his poetry (ghazal and geet), fiction, and his work on fostering inter-faith harmony.
In 1991 Prof Abbasi had set up, and has led since then, a research group on accident forecasting, risk assessment, and occupational safety at Pondicherry University. The group is among the most productive in Asia and has spearheaded the Indian R & D thrust in this field all through.
