Filtration media are lifesaving components in an expanding global economy. They help keep the population healthier and safer and the environment pristine. Filter media are used in many diverse industries and applications. They provide safe drinking water in arid areas where water is in short supply. They are also used to purify pharmaceuticals and keep them free of viruses. They also clean process wastewater in the chemical and metal industries before discharge into rivers and streams. The need for filtration media is going to increase many-fold as the world population increases and water shortages become commonplace.
