Today we begin a six-part series on the Great Lakes of North America, starting with Lake Erie.

Filters-A Short History

Water filtration is an important part of the treatment process. A water filter removes impurities from water by means of a fine physical barrier, a chemical process or a biological process. Filters use sieving, adsorption, ion exchanges, and other processes to remove impurities. Unlike a sieve or screen, a filter can remove particles much smaller than the holes through which the water passes. Modern-day treatment plants use […]
