Bio augmentation Overview

A promising long-term and sustainable solution to the growing scarcity of water worldwide is to recycle and reuse wastewater. In wastewater treatment plants, the biodegradation of contaminants or pollutants by harnessing microorganisms present in activated sludge is one of the most important strategies to remove organic contaminants from wastewater.

Bioaugmentation is the practice of adding cultured microorganisms into the subsurface for the purpose of biodegrading specific soil and groundwater contaminants.

The bacteria feed on the contamination, deriving nutrition for growth and for reproduction. Complex chemical reactions occur, but the result of this natural process is that contaminants are used up completely or are converted (or cleaved) into an innocuous product such as water and carbon dioxide. The microbes will survive and consume their contaminant food source until the unwanted pollutant is remediated.
