First, Brittany told us a little bit of information about the Alcosan facilities and how waste water is processed and treated. The water starts off as dirty sewer drainage filled with all sorts of gunk in it. The 'junk' is filtered out through a series of segments, including bar screens, grit chambers, and even an airated tank full of micro-organisms!
The jar on the left is waste water before any processing. Gross! The middle jar is the waste product after the water has been filtered. The jar on the right is the filtered water that is returned to our rivers and streams, where it is eventually processed for home use.
Join us next Wednesday, March 16 with our friends from Carnegie Library of Pittsburgh's outreach team for a SURPRISE activity! Bring a friend and let's have fun together! See you there!
