STEP 8 – Getting Rid of Germs with UV Light
We Get Rid Germs Like the River Does – With UV Light!
Before the cleaned wastewater flows into the river we have to make sure it is harmless. We use ultraviolet (UV) light to make sure we are not putting harmful germs into the river. The UV light breaks up the DNA of any germs or bacteria in the water. They will not be able to make new copies of themselves. That means they cannot hurt any plants or animals.
