Água: da contaminação à origem da solução | Vania Calisto | TEDxAveiro


water is such a spit many times

we take it for granted

only 3% of the whole water body

there are now 663 million

people without access to a secure source of

but once again we have the same problem

and they are not applied in any way

conventional water treatment

this cost is not essentially

euros per kilo

this cost is naturally affected by
