Bioaugmentation in wastewater treatment involves introducing specialized, often pre-adapted microorganisms—such as bacteria or yeasts—to strengthen the degradation of difficult pollutants like hydrocarbons, cyanides, and high-COD wastes. This approach improves overall treatment performance, supports faster recovery from process upsets, and provides a cost-effective, environmentally friendly way to meet discharge requirements without significant infrastructure changes. In essence, bioaugmentation supplements the native microbial community with targeted biodegraders to better manage industrial effluents and challenging operating conditions.
