Kalamazoo wastewater treatment plant
On October 22, 2011, a group of students from the class of CHEG 2610 visited the Kalamazoo Water Reclamation Plant (KWRP) to learn more about the process to treat wastewater around the Kalamazoo area.

After the presentation ended, each of us was required to wear goggle and helmet protection for the tour around the KWRP. The tour began in the administration building where computer systems are located to monitor the process within the plant.

The first station that we visited was the Raw Wastewater Pump Station, all the industries and municipal wastewater flow in this station first. This station is used to remove debris from the wastewater.
