Osmosis – Purifies Water and Purifies Blood

An SPM is a material designed with a pore size that lets specific materials pass through it, while blocking others. In water purification the membrane allows water to pass, but blocks salts, bacteria and other solids. We also learned that when a SPM separates a highly concentrated solution from a less concentrated solution…
