Oxigest: A Powerful Tool for Wastewater Treatment

Oxigest is a term often encountered in the world of environmental and water treatment, particularly in the context of extended aeration wastewater treatment systems. This term, a registered trademark of Smith & Loveless, Inc., refers to a specific type of cylindrical package extended aeration plant designed for efficient and reliable wastewater treatment.

What is Extended Aeration?

Extended aeration is a wastewater treatment process that utilizes aerobic bacteria to break down organic matter in the wastewater. The process involves:

  • Aerating the wastewater: This step introduces oxygen into the water, which is essential for the growth and activity of aerobic bacteria.
  • Prolonged aeration: Unlike other treatment processes that involve shorter aeration periods, extended aeration keeps the wastewater in contact with oxygen for a significantly longer duration. This extended contact time allows the bacteria to effectively break down organic matter.
  • Clarification and sludge removal: Once the organic matter is broken down, the wastewater is clarified to remove the remaining solids. The sludge, consisting of the dead bacteria and other solids, is removed and disposed of or further treated.
