Ferric Chloride: Clearing the STUFF Out of Water

Wastewater is the water that flows down our drains after we use it for washing, bathing and flushing. Before it is released to rivers, lakes and oceans, wastewater takes a detour of its own--to the wastewater treatment plant. There, ferric chloride is used to clear the water of particles. And chlorine and other disinfectants destroy harmful germs.
