A New Solution to Water Purification in Rural Areas

A New Solution to Water Purification in Rural Areas A New Solution to Water Purification in Rural Areas A New Solution to Water Purification in Rural AreasIts been said that water is life, as necessary as food and oxygen to human survival.But theres another side to that story.Unsanitary water can also be a health risk, killing more than 500,000 people worldwide every year, according to the World Health Organization. And this schwierigkeit is only going to get worse. By 2025 half of the worlds population will be living in what are known as water-stressed areas, where access to clean water is limited or nonexistent. Some 844 million people will lack basic drinking water and another 159 million will be dependent on untreated surface water surces.This is primarily a problem in the developing world, where as many as 38 percent of health care facilities are operating without modern water treatment and roughly the same amount dont even have clean soap and water for hand washing. These are r egions where clean water is hard to come by and related illnesses, including cholera, dysentery, typhoid and more, are widespread. Money and investment to solve these problems are also limited, preventing developments that could save lives.Enter Guihua Yu and his research team at The University of Texas at Austin.For You Technology Brings Clean Water and Nutrition to Central AmericaYu, a professor of materials science and mechanical engineering at the school, has developed a new, low-cost way to treat water safely and effectively in the field without the need for electricity or powered components using a distillation process that combines gel-polymer materials and the power of the sun.Right now, people fruchtweinly use multi-stage flashing or multi-effect distillation for water desalination, Yu says. So basically you need to get rid of the salt so the water can become drinkable. But these traditional industrial scale technologies require a lot of energy and they also require very significant infrastructure.New technology could benefit hundreds of thousands of people with restricted access to clean drinking water.The Texas teams solution eliminates both of these needs by tapping solar energy to drive its process. Arguably the cheapest, most abundant energy source in the world, solar allows water samples to be purified anywhere, at any time, without any specific infrastructure or tools. Distillation is a common technique for producing clean water, and the development by Yus team utilizes hydrogels networks of polymer chains that offer high water absorbency rates with both hydrophilic (attracted to water) and semiconducting (solar-adsorbing) properties, allowing for the production of safe drinking water from almost any source, from seawater to contaminated freshwater.Thats a potential game-changer for water safety in the developing world.A Materials SolutionIn this work we actually used a hyper-hydrogel, Yu says. That means that this hydrogel is not one compo nent, but rather is actually two different polymers that are chemically blended together. One polymer is a water-soluble polymer called a polyvinyl alcohol, or PVA. So PVA can actually store water, and it can contain a very significant amount of it, typically over 95 percent. The other component is called polypyrrole (PPy) that has a molecule structure that is conjugated so they can actually act as a semi-conductor just like solar panels. Polypyrrole is one of the components that can absorb the solar energy so you convert solar energy to locally heat up these polypyrrole, polyvinyl and PVA networks.Its a complex process, but it works.The hydrogel, which already contains a lot of water, heats up by absorbing energy from the sun. Once the level of water in the hydrogel is evaporated off and distilled, it starts to pull in untreated water that begins to evaporate. By evaporating the water off and capturing it youre able to get rid of whatever salt or other contaminates are in the water , making it safe for drinking. Its a self-sustaining system that replenishes itself over and over again and keeps treating water until the solar energy used to power the evaporation runs out.Desalination was used to demonstrate the technologys potential because salt is notoriously difficult to remove from water. The hydrogel-based system can also filter out a number of different contaminants or pollutants from unsafe water.Its also worth noting that the hydrogel material can be used over and over again it doesnt get clogged up with salt or contaminants and replaced between uses. As long as the hydrogels are kept wet so that salt cant crystallize they can work continuously for long periods of time. In testing, Yus team demonstrated that the system could operate unimpeded for more than a month without any decay in overall performance.The findings were first published in Nature Nanotechnology.Scaling PurificationRight now, Yu says the hydrogel materials that are used in the process are focused on household use, with 8- to 12-inch wafers that can be used to treat a few gallons of water at a time. At that scale, he says, the technology can likely have the most immediate impact.Even given this current system with the current materials, its not like we are talking about spending $1,000 to build this instrument, Yu says. You can have a simple design with a container and these solar-sopping hydrogel materials and then just start collecting water. Because it can be continuous use, we dont need to have a cleaning system, so you can just put it into the sink and if you have a continuous water supply you dont even need to do anything to enable this water washing.Yu, who has two patents related to this hydrogel technology, says the next step for his team is to find even cheaper, better performing materials than the PVA and PPy that the system currently uses and to find ways to truly scale the system. Theyre working with water researchers and civil engineers at the universit y to develop more systematic evaporation systems that are capable of solar-treating far larger water samples than is currently possible, focusing on bacteria and foreign organic materials contamination.We are ready to partner with industry to look into really translating our research to household use at first and then, as we find better and cheaper materials, I think we are going to be ready to work with bigger roles, Yu says.

Dont mess up these words on your resume

As Business Insider notes, to ensure something is to make sure that something is the case. To insure is to provide or obtain insurance.DefinitelyA surprising number spell this as definately.Be sure not to misspell any of these words, eitherLadders has also compiledour own list of words that might be making you look bad at work - the Oxford English Dictionary says these are commonly misspelled words, based on the Oxford English Corpus.You wont want to get these ones wrong on your resume.KnowledgeOxford says to remember the d, because this is often spelled like knowlege.ColleagueOxfords memory trick is -ea in the middle, and says that this word is often spelled like collegue.BusinessOxford recommends keeping in mind that this word begins with busi-, because its often spelled like buisness.Liaise, LiaisonHere was Oxfords suggestion remember the second i liais-- the dictionary says that liase, liason are how these words are commonly misspelled.Heres how to avoid spelling traps on resumesIts easy to fall into these, but you dont have to.Go through it, word for wordCareer expert Alison Doyle writes about how to do this in The Balance.Spell check then proofread by placing a finger on each word and then have your document reviewed by a career coach or a friend or family member. Its hard to catc h your own mistakes, so having someone else read your resume for you will help. Reading it out loud is another option for catching mistakes, she writes.Get an expert on your sideSarah Landrum, a freelance writer, Digital Marketing Specialist and founder ofPunched Clocks, writes about this in Entrepreneur.While you may not need professional editing services each and every time you send in a resume, hiring an editor to comb through your resume before you hit the job market hard is a good idea. Because it is an editors job to look for mistakes and make suggestions, they can ensure youre sending in the best version of your resume possible, she writes.She adds In addition to your resume, they can also proof your application, cover letter, portfolio and other crucial correspondences. Consider hiring an editor with experience editing resumes. The writing you use in a resume is typically much more direct than someone would use in sales copy or in a novel. Using an editor who specializes in editing job search documents can give you a leg up on the competition.
