How Does A Sewage Treatment Plant Work?

A sewage treatment plants typically uses a combination of physical, biological, and chemical processes to treat wastewater.

  • Preliminary Treatment

The first step is to remove large solid objects, such as rags, sticks, and plastics, from the wastewater. One can usually do this with screens and grit chambers.

  • Primary Treatment

In this stage, the wastewater settles in large tanks or basins. Later, you need to remove the solids that settle to the bottom. This process is called sedimentation or primary clarification.

  • Secondary Treatment

After primary treatment, the wastewater goes through a biological process, where microorganisms break down the remaining organic matter. This takes place in aeration tanks, where the wastewater combines with air to provide oxygen to the microorganisms. The microorganisms then use the organic matter as food, converting it into carbon dioxide, water, and more microorganisms.

  • Tertiary Treatment

In some cases, the treated wastewater may go through additional treatment to remove nutrients, such as nitrogen and phosphorus, which can cause environmental problems if released in high concentrations. One can easily do this with biological or chemical processes, such as adding chemicals to remove phosphorus or using a sand filter to remove nitrogen.
