1. Screening - Large and small objects are removed, like towels, sand and gravel.
2. Primary Clarification - Grease and oil float to the top of large settling tanks.Solids sink to the bottom and are collected to make energy.
3. Biological Treatment - Microscopic organisms, "bugs", break down organic material.
4. Disinfection - Disease causing organisms are killed by chemicals that are then neutralized. Clean water is returned to Lake Michigan.
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.
