Today, nearly one fifth of the world's population lives in water-scarce areas. By 2025, that number will rise to 1.8 billion people. From drinking water to fishing ground water to wastewater treatment, we need to radically change access to and use of water to survive. When we need it most, 3D printer technology is sparking a water revolution.3D printing can treat polluted water economically and efficiently in the water and wastewater industry. 3D printing technology opens the possibility of breakthrough renovation of water infrastructure.1. Improving the water quality of fish farmsFisheries or aquaculture account for 47% of global fish production, and Fisheries account for the majority of global market growth, which is necessary to meet human consumption needs. As fisheries become more and more important, the science behind commercial aquariums and fences also needs to be developed. Wild water systems are naturally balanced, but not commercially operated, and the acidity of water quality must be controlled.The integration of 3D printing and fish farms has led to innovations in water quality testing. The new system can now send remote notifications to monitor water quality. Over time, this cost-effective approach will make fish farms more cost-effective.2. Desalination produces drinking waterIt is estimated that the world's population will increase by another 40-50% in the next 50 years, which will lead to increasing water scarcity. Water is used for irrigation, household use and industry, but only a small part of the world's water is drinkable.The U.S. Department of Energy is developing plans to use 3D printers to economically and efficiently desalinate water. Desalination is the process of removing mineral components, such as salt, from water. By creating this technology with 3D printers, there may soon be a way to effectively increase the global water supply._Photos of Ivan Bandura in Unsplash3. Cheap Portable Water AnalysisIn reality, the use of polluted water is one of the main causes of death in developing countries. Poor water quality can lead to disease, which is usually fatal. To solve this problem, more effective methods are needed to test and measure water quality. For these rural communities, this means finding a way to test water quality remotely, economically and efficiently.To this end, researchers have developed a simple 3-D printing device that can test water quality remotely. The technology uses a digital camera with a resolution of 8 million pixels to record the color changes required for colorimetric analysis. The device is powered by batteries and processed by wireless connection. Technologies like this will save lives by identifying pollutants in our water system.4. Water Purification and FiltrationAlthough purification and filtration systems can now be manufactured over a long period of time, they can be manufactured economically and efficiently in a short period of time through 3D printing technology, which means that the filtration system can now reach the most needed places and people.Depending on nanofiber membranes, electrospun 3D printing technology is now used for printing. Products like bare filters use 3D printing technology to make porous filters 70-80% less than traditional filters, so they are more effective in preventing pathogenic microorganisms such as Salmonella or Escherichia coli.5. Efficient Wastewater TreatmentAccording to the World Water Resources Development Report 2014 (WWDR) of UN-Water, more than 80% of the world's water is not collected or treated. China and India are developing rapidly, but water infrastructure is also required to keep up. Wastewater treatment is relatively expensive in these countries, which is why the cost-effective 3D printing technology has proved revolutionary.Preventing untreated water from entering the environment is crucial because suspended solids, biodegradable organic matter, pathogens and nutrients may be harmful to the environment. As water shortages intensify, technological improvements in wastewater treatment become more important.3D printing technology is very innovative, such as pumps and feeding gaskets, these items can be produced by 3D printers, and these printed items are of high quality, which saves a lot of costs compared with traditional 3D printer technology.3D printing technology will have a revolutionary impact on water quality improvementSource from: www.creality3dpro.storeCREALITY 3D OFFICIAL DIRECT GLOBAL STOREWith the increase of water shortage and population, our demand for water system becomes more and more tense. Advances in 3D printing technology have helped to create breakthrough technologies to improve our environment and transform communities in need.
