Hybrid Stand-Alone System for Clean Water under Emergency Conditions
Explain your project in details:
Stand-Alone Hybrid System: means that all the necessary equipment can be placed in a 6.0 meters ISO container which can stand alone and autonomously, to produce clean drinking water for a logical time period standing as an off-grid solution. Hybrid because it combines wind and solar energy with diesel power supply as a back-up energy source if needed. NF-RO Desalination Unit: Nanofiltration - reverse osmosis, because two solutions of different concentrations are separated by a specific semi-permeable membrane and the water with less salinity will be diffused through the membranes into the concentrated product. Thus, when suitable pressure applied to the concentration output, clean drinking water will flow through the membrane to the diluted output leaving behind dissolved salts and other impurities. NF and RO membranes were selected because this technology is applied in a rig which combine nanofiltration and reverse osmosis modules respectively.
Impact of your enterprise on sustainable development
Three main tasks investigated through the research project: a) The feasibility of a stand-alone solution in order to produce adequate according to WHO, drinking water for 300 inhabitants (case study) - Village Mallar - India. b) Use mainly of renewable energy sources that could be considered as electricity suppliers and evaluation of the relationship between the energy contribution-consumption c) Experimenting with a reverse osmosis and nano-filtration rig, has actually been tested at Aston University and worked. Simulating solar energy as the only sustainable input I was able to provide clean drinking water from a high saline mixture. Also, I have tested 6 different regions around the world by simulating their physicochemical synthesis of water. The resulted water product has been actually tested by an external company to see if complies with WHO standard. In almost all the cases the water was complying with the WHO guidelines. The whole project has been investigated and conducted for a realistic scenario where 300 people need water urgently. According to WHO 1,232 litres (1.23m3/day) of fresh water are necessary for 300 people to survive. Hence, 1.5m3/day was taken under consideration through the system's design. The water production was calculated equal to 1.271m3/day which is bigger than the real water demand using only renewable energy sources. If we include secondary energy sources (diesel generator) or even the back up water tank, then their is enough drinking water for 300 people to survive nearly 10 days. Based on the renewable energy sources the system can be autonomous completely as the solar+wind energy will be stored in a battery bank.
Sustainability and future plans
Recommendations - Future Directions a. Wind turbine necessity: HOMER indicated that a wind turbine with such a size is not useful in terms of energy contribution and with respect to the cost. Therefore it can be a first back-up energy supply when little air flow is available. b.The system power supply is adequate to produce fresh water for 300 inhabitants: Thus, the energy proposed contribution should be followed. A battery bank is useful especially in energy scarcity circumstances. c. Generating power from salt: as salt is an abundant raw material exists in brackish and sea water, production of energy from salt is feasible. Many researchers are referring to microbial fuel cells (MFC) which use wastewater and bacteria to produce electricity and reverse electrodialysis (RED) which produces energy from the salt obtained by the water desalination. A combination of these two technologies offers the combined technology called as: microbial reverse-electrodialysis cell (MRC) [Logan B. & Rabaey K., 2012]. d. A collaboration of a PLC unit with the rig system may be integrated. There is the capability with the help of software for the user to enter the coordinates and the altitude of the location the container is being established, in order to automatically adjust the PV panels' inclination every hour per day. E.5 - Payment Calculation Data (the instalments are considered in £) , Bank = Lloyds TSB, Interest rate = 7.4%, Principal loaned amount = £24,310 Term loan = 5 years , Monthly interest rate = 0.616% A 5 year payment period estimation has been considered. A scenario has been made in order to calculate the monthly instalments as well as the interest rate. The loan amount is the 50% of the initial project
Your profile as an entrepreneur
My name is Theo Margazoglou and I was born in July 1983 in North Greece. I am postgraduate mechanical design engineer with nearly 10 years of experience in various companies in Greece and U.K. I also act as a mentor & sponsor for developing engineers while I am Chartered engineer within the Institution of Mechanical Engineers. Currently I am heavily involved in Automotive industry as a Lead Engineer in JLR (M-Tec Engineering projects). This project was my research project for my Master of Science in Mechanical Engineering at Aston University - Applied Sciences Department under the supervision of Dr. Philip Davies. The project includes the engineering design of the system based on a case study of the village Malar in India, as well as experimental work simulating approximately the water of 6 different locations (US Texas, Edwards - Trinity Aquifer, South Australia - Eden Valley - Upper Marne River Catchment, Upper Egypt - West Tahta area, India - Haryana State (village Malar), N.W. China - Qinghai province (Zhangye basin) , Southeast Spain, Detritic aquifer: to examine the drinking solutions achieved at the rig of Aston University, by applying nanofiltration followed by reverse osmosis membranes. Different salinity, pressures and power applied in four separate thorough experiments. Samples kept and a physicochemical analysis of the water parameters is followed at the end of the thesis to investigate the water quality received from the six locations simulated from all over the world. My motivation is to publish this idea and presented it to the outside world. Many people have already seen it and recognised the high potential of this project already, which could really save lives in locations they are not easy accessible, especially under emergency conditions. This is a compact solution that can be "plug and play"and offer purified drinking water.
