The Four Stages To Cleaning Wastewater
||Large and small objects are removed, like towels, sand and gravel.
|Grease and oil float to the top of large settling tanks.
Solids sink to the bottom and are collected to make energy.;
|Microscopic organisms, "bugs", break down organic material.
||Disease causing organisms are killed by chemicals that are then neutralized. Clean water is returned to Lake Michigan.
The Good Bugs
|The bugs we use for cleaning wastewater are actually famous! When they're done doing their jobs in the water reclamation facilities, we dry them out and turn them into Milorganite®, a fertilizer trusted and used by lawn and gardening experts since 1926. You can even see Milorganite® in the movie Caddyshack.
