The material is made from special nanoparticles combined with low-cost polymers such as polypropylene (PP), commonly used for plastic grocery bags.\nIt is said to be easier and more environmentally friendly to manufacture than the conventional polyvinylidene fluoride (PVDF) membranes used by developed countries.\nWhile similar membranes made from PP are available in the market, they are usually only suitable for home use since they break easily when subjected to cleaning procedures in commercial plants.\nDelivering clarity\nHowever, with a new nanocomposite structure developed by NTUS School of Materials Science and engineering professor Hu Xiao and the Atera Water team, CLARITY is estimated to be two to three times stronger than the other PP membranes in the market.\nSIT and Atera Water then incorporated CLARITY membranes into an innovative water treatment system named TeraStream, which takes advantage of the increased robustness and lower cost.\nPVDF membrane systems are currently too expensive to purchase and operate for communities in developing countries. Moreover, they require skilled labour due to sophisticated controls and tight operating ranges, which can be difficult to maintain outside of large cities.\nIncorporating cutting-edge fluid dynamic modelling, assistant professor Elisa Ang, associate professor Victor Wang, associate professor An Hui, and Dr Peter Beshay from SIT’s engineering cluster worked with Atera Water closely to design TeraStream, enabling it to handle the challenging environments found in developing countries.\nTeraStream aims to replace the rudimentary sand filter systems used in many regional countries such as Vietnam and Indonesia, says Atera Water chief executive and co-founder, Dr Adrian Yeo.\n“These sand filters which used to work for the last century are now unable to purify the increasingly polluted water in the ground and rivers in many countries, due to reasons such as over-exploitation of water resources, climate change and pollution from industries,” he added.\nTeraStream was piloted in Vietnam from March to August 2023 and will be deployed in a 10,000m3\/day water treatment facility in Ha Tinh Province in northeastern Vietnam. The amount of clean drinking water generated daily is said to be the equivalent of four Olympic-sized swimming pools (50m x 25m x 2m).\nA Letter of Intent (LOI) has been presented by Vietnamese water utility company HT Thanh Trung Co. Ltd. to Atera Water, for a contract to provide some 30,000 people with piped access to clean water.\nDinh Minh Dao, chairman of HT Thanh Trung, said: “Ha Tinh is currently experiencing the effects of climate change, which has created water stress in the area. We have been searching for an invention that can sustainably produce water at a large scale – we are confident that we have found that in TeraStream. We are happy to collaborate with our Singaporean partners and look forward to deploying TeraStream in Ha Tinh as well as our other facilities.”\nAyesa wins Spanish wastewater treatment projects\nGalliford Try scales up Environment and water operations with new division\nSustainability at its core\nThe three partners share the same commitment to tackle the effects of climate change using sustainable solutions, so every facet of the TeraStream was designed with sustainability in mind.\nCLARITY membranes are made using a unique melt-stretching method requiring zero harsh chemicals. The PP polymer and nanoparticle compounds are combined during the process to make a straw-like hollow fibre structure that has a slit-like pore structure. Despite allowing water to pass through faster, the slits can still block up to 99.99% of solid contaminants and microorganisms.\nThese nanoparticle compounds were specially selected with help from professor Hu, who has pioneered sustainable ways to create new composite and hybrid materials.\nAssistant prof essor Ang, who led the SIT team, said: “To achieve sustainable clean water production, it is crucial to design a system that features a good flow of water and efficient use of energy.\n“Our partnership with Atera Water represents the integration of translational research and real-world impact. At SIT, we have harnessed our applied research expertise to tackle the pressing challenges surrounding sustainable water production, and achieved an outcome with the potential to forge a more sustainable and meaningful future in clean water production.\n“This project also gives our students the opportunity to understand and participate in solving a real-world challenge.”\nBy carefully controlling the water flow – also known as hydrodynamics – within the system, TeraStream is able to operate at a low and stable water pressure, which can reduce chemical and electrical consumption by up to 90% versus conventional systems. It also generates no sludge, which could potentially save up to 3,000 tonnes of carbon annually.\nIn comparison, conventional PVDF membrane systems are designed to operate at a higher water pressure, thus consuming significant amounts of electricity and chemicals to maintain. It requires frequent cleaning to remove contaminants, which forms waste sludge that needs to be treated and landfilled.\nAdditionally, the production of PVDF hollow-fibre membranes generates a large amount of waste chemical pollutants, which also need to be treated further before they can be discharged, resulting in a larger environmental impact and carbon footprint.\nGlobal application\nAs a made-in-Singapore product, TeraStream will be manufactured in Atera Water’s facility in Jurong, but the company plans to export the product globally.\nIt was first conceived by Dr Yeo and his co-founder Ms Tai Kee in 2022 during the COVID-19 pandemic and successfully piloted in Vietnam for six months earlier this year, which paved the way for the upcoming deployment.\nAssociate professor Susanna Leong, vice president of applied research) at SIT, said: “Sustainability is a key priority in SIT’s applied research pursuits, where we aim to support solutions aligned to the Singapore Green Plan 2030.\n“As a university of applied learning, our research focuses on bridging the gap between discovery-driven research and application, to deliver impactful solutions to industry and provide our students with authentic learning opportunities.\n“Our collaboration with Atera Water and NTU is a wonderful example of how we help to unlock the economic value of a technology platform through translational research.”\nTai, Atera Water’s chief operating officer, added: “For many communities, they cannot afford the best-in-class water filtration systems due to high costs, and yet their existing sand filters are failing. Can we provide better clean drinking water to communities in Southeast Asia at the same cost?\n“I believe our innovation can aid the millions of people in water-stressed countries, especially in the face of climate change. Coming from\nSingapore\n, which transformed from a nation facing water scarcity to a global water hub today, we want to take this water story further by using our technological expertise to bring affordable clean water to the rest of the world.”\nImage credit: Courtesy of Singapore Institute of Technology.

PVDF membrane systems are currently too expensive to purchase and operate for communities in developing countries. Moreover, they require skilled labour due to sophisticated controls and tight operating ranges, which can be difficult to maintain outside of large cities. Incorporating cutting-edge fluid dynamic modelling, assistant professor Elisa Ang, associate professor Victor Wang, associate professor An Hui, and Dr Peter Beshay from SIT’s engineering cluster worked with Atera Water closely to design TeraStream, enabling it to handle the challenging environments found in developing countries. TeraStream aims to replace the rudimentary sand filter systems used in many regional countries such as Vietnam and Indonesia, says Atera Water chief executive and co-founder, Dr Adrian Yeo. “These sand filters which used to work for the last century are now unable to purify the increasingly polluted water in the ground and rivers in many countries, due to reasons such as over-exploitation of water resources, climate change and pollution from industries,” he added. TeraStream was piloted in Vietnam from March to August 2023 and will be deployed in a 10,000m3/day water treatment facility in Ha Tinh Province in northeastern Vietnam. The amount of clean drinking water generated daily is said to be the equivalent of four Olympic-sized swimming pools (50m x 25m x 2m). A Letter of Intent (LOI) has been presented by Vietnamese water utility company HT Thanh Trung Co. Ltd. to Atera Water, for a contract to provide some 30,000 people with piped access to clean water. Dinh Minh Dao, chairman of HT Thanh Trung, said: “Ha Tinh is currently experiencing the effects of climate change, which has created water stress in the area. We have been searching for an invention that can sustainably produce water at a large scale – we are confident that we have found that in TeraStream. We are happy to collaborate with our Singaporean partners and look forward to deploying TeraStream in Ha Tinh as well as our other facilities.” * - [Ayesa wins Spanish wastewater treatment projects](https://buildindigital.com/ayesa-wins-spanish-wastewater-treatment-projects/) - [Galliford Try scales up Environment and water operations with new division](https://buildindigital.com/galliford-try-scales-up-environment-and-water-operations-with-new-division/) * ## Sustainability at its core The three partners share the same commitment to tackle the effects of climate change using sustainable solutions, so every facet of the TeraStream was designed with sustainability in mind. CLARITY membranes are made using a unique melt-stretching method requiring zero harsh chemicals. The PP polymer and nanoparticle compounds are combined during the process to make a straw-like hollow fibre structure that has a slit-like pore structure. Despite allowing water to pass through faster, the slits can still block up to 99.99% of solid contaminants and microorganisms. These nanoparticle compounds were specially selected with help from professor Hu, who has pioneered sustainable ways to create new composite and hybrid materials. Assistant prof essor Ang, who led the SIT team, said: “To achieve sustainable clean water production, it is crucial to design a system that features a good flow of water and efficient use of energy. “Our partnership with Atera Water represents the integration of translational research and real-world impact. At SIT, we have harnessed our applied research expertise to tackle the pressing challenges surrounding sustainable water production, and achieved an outcome with the potential to forge a more sustainable and meaningful future in clean water production. “This project also gives our students the opportunity to understand and participate in solving a real-world challenge.” By carefully controlling the water flow – also known as hydrodynamics – within the system, TeraStream is able to operate at a low and stable water pressure, which can reduce chemical and electrical consumption by up to 90% versus conventional systems. It also generates no sludge, which could potentially save up to 3,000 tonnes of carbon annually. In comparison, conventional PVDF membrane systems are designed to operate at a higher water pressure, thus consuming significant amounts of electricity and chemicals to maintain. It requires frequent cleaning to remove contaminants, which forms waste sludge that needs to be treated and landfilled. Additionally, the production of PVDF hollow-fibre membranes generates a large amount of waste chemical pollutants, which also need to be treated further before they can be discharged, resulting in a larger environmental impact and carbon footprint. ## Global application As a made-in-Singapore product, TeraStream will be manufactured in Atera Water’s facility in Jurong, but the company plans to export the product globally. It was first conceived by Dr Yeo and his co-founder Ms Tai Kee in 2022 during the COVID-19 pandemic and successfully piloted in Vietnam for six months earlier this year, which paved the way for the upcoming deployment. Associate professor Susanna Leong, vice president of applied research) at SIT, said: “Sustainability is a key priority in SIT’s applied research pursuits, where we aim to support solutions aligned to the Singapore Green Plan 2030. “As a university of applied learning, our research focuses on bridging the gap between discovery-driven research and application, to deliver impactful solutions to industry and provide our students with authentic learning opportunities. “Our collaboration with Atera Water and NTU is a wonderful example of how we help to unlock the economic value of a technology platform through translational research.” Tai, Atera Water’s chief operating officer, added: “For many communities, they cannot afford the best-in-class water filtration systems due to high costs, and yet their existing sand filters are failing. Can we provide better clean drinking water to communities in Southeast Asia at the same cost? “I believe our innovation can aid the millions of people in water-stressed countries, especially in the face of climate change. Coming from [Singapore](https://buildindigital.com/?s=singapore), which transformed from a nation facing water scarcity to a global water hub today, we want to take this water story further by using our technological expertise to bring affordable clean water to the rest of the world.” Image credit: Courtesy of Singapore Institute of Technology.

Readable Markdown	### Singapore start-up, Atera Water is working with scientists from two of the city-states’ academic technology institutes to make the large-scale production of clean water more affordable for developing nations A local tech start-up working with scientists in Singapore has developed a new type of membrane-based water filtration system that provides more affordable large-scale production of clean water. Atera Water teamed up with scientists from Nanyang Technological University, Singapore (NTUS), and the Singapore Institute of Technology (SIT) to develop the new system, which is said to have only half the carbon footprint of conventional water treatment plants. The system is made possible through an efficient nanocomposite membrane named CLARITY. The material is made from special nanoparticles combined with low-cost polymers such as polypropylene (PP), commonly used for plastic grocery bags. It is said to be easier and more environmentally friendly to manufacture than the conventional polyvinylidene fluoride (PVDF) membranes used by developed countries. While similar membranes made from PP are available in the market, they are usually only suitable for home use since they break easily when subjected to cleaning procedures in commercial plants. ## Delivering clarity However, with a new nanocomposite structure developed by NTUS School of Materials Science and engineering professor Hu Xiao and the Atera Water team, CLARITY is estimated to be two to three times stronger than the other PP membranes in the market. SIT and Atera Water then incorporated CLARITY membranes into an innovative water treatment system named TeraStream, which takes advantage of the increased robustness and lower cost. PVDF membrane systems are currently too expensive to purchase and operate for communities in developing countries. Moreover, they require skilled labour due to sophisticated controls and tight operating ranges, which can be difficult to maintain outside of large cities.
