When you think about water purification, the only one that comes to mind is water purifier: study finds
Water purification systems use water to purify the atmosphere, and the world is in dire need of water purifying technology.
But a new study finds that the most effective water purifiers on the planet have less than one percent of the water needed to purifier a small room.
Water purifiers are the mainstay of many homes and businesses, but there are also a growing number of systems, such as the HEPA air purifiers and HEPA-A systems, which purify water by heating the air, then turning it into steam, that can be built into homes, and which also purify air, but they’re not perfect.
Researchers from the Massachusetts Institute of Technology (MIT) looked at a variety of water systems to determine which ones could achieve the best efficiency, and they came up with a list of more than 50 that could perform the job.
The team also looked at how water purifies on a larger scale, looking at different water systems that use more than one person to run.
It’s a bit of a catch-22, the researchers said, because there are no easy-to-use methods that can perform the task, and there’s no simple answer for how to get the water to be pure enough.
“In our study, we found that a few key characteristics of water use systems and how they were used differed across a number of water sources, and this could lead to different efficiency,” said Rui Lu, a professor of mechanical engineering at MIT and lead author of the study, in a statement.
“In the future, we will explore how to improve water purifications and how best to optimize these systems to achieve the highest efficiency.”
Researchers found that some of the most efficient water purizers were in the HEA air purification and HEAPA-A water purificators, which are not perfect, but their efficiency was still impressive, at less than 1 percent.
They also found that HEPA systems had a higher efficiency than HEPA tanks, which have a lower efficiency than regular tanks, and were also more efficient than HEAPAs, which use a mixture of water and steam to purifying water.
For the researchers, this study was a bit surprising, because it found that the systems with the highest performance, while not perfect at all, could still be effective at getting the most water from the air.
“We are surprised at the efficiency of the systems that we studied, and we think that there are other methods that could be developed that can achieve the same results, especially in terms of efficiency,” Lu said.
