- Water Science and Engineering
Prior to coming at Cranfield, Neha has completed a master’s degree in water engineering from the University of Strathclyde, Glasgow in 2018. In addition to that, she also hold a bachelor's in Civil Engineering obtained in 2016. The master's program also included a three-month placement where she contributed towards designing freshwater and sewage pipeline for a ship to shore connection in Glasgow. The placement required using specialist knowledge and design skills along with making complete hydraulic profile for the new connection- this included designing for a range of pressures suitable for on-board energy consumption, selecting suitable pipe material, conducting environmental impact assessment (EIA) for the new connection. The placement was also rewarding as she got the opportunity to work closely with specialist marine water engineers. Towards the end, Neha gained valuable experience of working in freshwater and sewerage systems for on-board transportation.
Prior to coming at Strathclyde, she has worked full time as a valuation engineer where my responsibilities involved making property appraisal reports.
In the past, Neha has carried out research into understanding the benefits of water conservation for irrigation activities in semi-arid regions. Her work specifically involved doing a study for an agriculturally rain-fed region in central India. It elaborated investigation of rainfall-runoff relationships, evaluating infiltration and evapotranspiration of crops and understanding the net benefits obtained as an outcome of practicing water conservation. Apart from that, the research generated knowledge and understanding of the effects of water storage expansion on irrigation for enhanced resilience of crops plus the benefits. Additionally, the research also showed the influence of region-specific suitability factors and the ratio of water storage and rain-fed water demand. Finally, the results of applied water conservation were presented in terms of Water use efficiency analysis of the irrigated crops and benefit cost ratio analysis.
Currently, Neha is working on an industry-sponsored project that focusses on developing innovative wastewater treatment and recycling solution for railway rolling stock. The need for an on-board treatment unit stems from the current system of using control emission toilet tanks (CETs). CETs once full require to be emptied at the train depots, whilst freshwater tanks also need servicing. This often puts a strain on the rolling stock availability in the rail network as the trains have to be taken out of service. Also, during high passenger demand, CETs run the risk of reaching their capacity rapidly which forces the toilets to be locked out of use, again causing inconvenience and making the system unreliable.
Her research involves developing a ‘safe waste’ sanitation unit which is able to manage its own waste rather than being dependent on municipal sewer systems-thus eliminating the need for CET tank. The project focusses on system integration using three physical processes to treat the on-board generated wastewater. The first process will be that of solid-liquid separation utilizing simple filtration technology. Subsequently, the separated liquid will be treated through cross-flow membrane filtration to target suspended and dissolved solids, bacteria and some viruses. Finally, the purified liquid stream will be passed through UV disinfection for complete sterilization of water. At last, the disinfected stream will be aimed to recycle for flushing toilets and potentially for handwash basins. Neha is specifically conducting research which includes development of each treatment process to demonstrate the ultimate ‘safe’ water quality for reuse.
