jätevedenpoisto
Jätevedenpoisto refers to the process of collecting and treating wastewater before it is discharged back into the environment. This process is crucial for public health and environmental protection. Wastewater, also known as sewage, originates from domestic sources like households, as well as industrial and commercial activities. It contains a variety of pollutants, including organic matter, pathogens, nutrients, and chemicals.
The initial stage of jätevedenpoisto involves the collection of wastewater through a network of sewer pipes.
Secondary treatment further reduces the amount of organic matter and suspended solids, often using biological processes
The sludge generated during treatment is also processed. It can be dewatered, digested to reduce its volume
