Cleaning sewage is important for protecting public health and the environment. Sewage contains harmful bacteria and other contaminants that can make people sick and pollute our waterways. Sewage treatment plants remove these contaminants from sewage so that it can be safely released back into the environment or reused for other purposes, like irrigation.
There are many different sewage treatment processes, but they all follow basic steps:
The cleanliness of water after sewage treatment depends on the type of treatment process that is used. However, all treated water must meet certain standards before it can be released back into the environment. These standards are set by the government and are designed to protect public health and the environment.
In general, water that has been treated to secondary standards is clean enough for most purposes, including swimming, fishing, and boating. However, some types of treatment processes, like tertiary treatment, can produce water that is clean enough for drinking.
Sewage treatment is an important part of protecting public health and the environment. By removing harmful contaminants from sewage, treatment plants help to keep our water clean and safe.
