Grundfos Solutions For Industrial Water Reuse

Water is such a fundamental necessity for life that it is often taken for granted. In modern industrial societies, the water from every tap is expected to be so pure that we can drink it without a second thought. However, the reality is much more complicated. Mankind is becoming increasingly aware that fresh water is a rarity, and the process of water treatment is vitally importance to us all. This white paper is intended to introduce the reader to the many elements that constitute the water reuse process.

EPA Researchers Explore Technology To Destroy PFAS

Per-and polyfluoroalkyl substances, otherwise known as PFAS, are a large group of human-made organic compounds with properties that make many of them toxic and persistent in the environment. PFAS have been manufactured and used since the 1940s in items such as fire-fighting foams, adhesives, cosmetics, paper products, and stain and water repellants. Until now, researchers have been unable to destroy PFAS in a way that has potential for larger scale use.
