Who needs a sieve when you can treat wastewater? Say goodbye to those pesky larger particles and organic matter, because we’re about to take cleanliness to a whole new level!

Pre-treatment: Removing larger particles and organic matter

Pre-treatment is a must for wastewater treatment. It focuses on the removal of larger particles and organic matter, making sure the following steps result in clean water. To make sure you’re pre-treating correctly, follow these four steps:

  1. Screening: Wastewater passes through a screen to remove things like plastics, paper, and debris. This stops them from clogging or damaging equipment downstream.
  2. Grit Removal: Wastewater streams into a grit chamber. There it slows down, so sand, gravel, and other heavy particles settle due to gravity. These are then removed before further treatment.
  3. Sedimentation: Wastewater flows into a settling tank or clarifier. Dirt and organic matter settle at the bottom due to greater density. The clarified water is then separated for further treatment.
  4. Flotation: Small and light particles, such as oil and grease, are removed using flotation. Air bubbles attach to them, making them rise to the surface and be skimmed off.

It’s important to note that pre-treatment makes the wastewater treatment process more efficient, reducing operational issues and enabling the proper functioning of subsequent units. For instance, a wastewater treatment plant in New York City saved millions of dollars every year by pre-treating.
