Around the world, more than a billion people lack access to safe drinking water, and more than 5,000 people a day die after drinking dirty water. Those facts are frightening, and water pollution problems caused by people are part of the issue. For the most part, in the United States, clean drinking water is not an issue, despite the fact that some 1.2 trillion gallons of untreated sewage, stormwater, and industrial waste are dumped into water sources. That doesn’t prevent most Americans from getting clean water when they turn on the faucet because of the wastewater treatment process that removes all kinds of dangerous items.
Typically, the wastewater treatment process goal is to remove organic matter, nutrients, solids, and bacteria that could cause diseases. To do that, it usually features three distinct levels. The primary stage removes large items including everything from old tires that worked their way into streams and rivers to more disgusting items like diapers and garbage. The secondary process is similar, and is used to get rid of smaller items that you would still be able to see. Tertiary treatments will vary from one system to the next, but they get rid of dangerous microbes and bacteria that you can’t see.
For the most part, the tertiary phase is the most important for getting rid of the most dangerous contributors to water pollution. Though little floaters in your water might be kind of gross, they aren’t always what can get you sick. Instead, it is microscopic germs and disease-carrying bacteria. It takes chemical treatments like chlorination to make sure they are killed off and water is clean to drink. Without that, even water that is crystal clear might cause you to get quite sick.
Many people take for granted the fact that clean drinking water is easily accessible, and getting a drink is as simple as turning on a faucet. However, there is a lot of work that goes into that, and wastewater treatment processes shouldn’t be overlooked. Without them, even the smallest amounts of pollution could cause a large number of people to become ill, especially when the cause isn’t found right away. As a result, treatment plants and entire systems play an important role in the majority of communities across the United States. Find more on this here: askhrgreen.org
