Bright idea for us­ing sun­light to pu­rify wa­ter

- Water Security · Science · Ecology · Social Issues · Society

SALTY wa­ter has been pu­ri­fied through the power of sun­light thanks to break­through tech­nol­ogy de­vel­oped by an in­ter­na­tional re­search h team led by Monash h Univer­sity ex­perts.

The pi­o­neer­ing pro- cess means brack­ish wa­ter and sea­wa­ter can be turned into clear drink­ing wa­ter within 30 min­utes.

The team uses a por­ous metal-or­ganic frame­work and sun­light to ab­sorb salts and de­sali­nate the liq­uid.

The method could pro­vide potable wa­ter for mil­lions of peo­ple world­wide and is cheaper and more en­ergy-ef­fi­cient than tra­di­tional de­sali­na­tion pro­cesses.

Lead au­thor Pro­fes­sor Huantin anting Wang (pic­tured) fr from Monash’s Dep part­ment of Chemic cal En­gi­neer­ing said th the work opened up a n new di­rec­tion for desi sign­ing ma­te­ri­als for w wa­ter pu­rifi­ca­tion. “Due to the avail­abil­ity of brack­ish wa­ter and sea­wa­ter, and be­cause de­sali­na­tion pro­cesses are re­li­able, treated wa­ter can be in­te­grated within ex­ist­ing aquatic sys­tems with min­i­mal health risks,” Pro­fes­sor Wang said.
