Bioaugmentation: an approach to biological treatment of pollutants

Biodegradation, 2023
Industrial development and the associated generation of waste requires attention for their management, treatment, and reduction without further degrading the quality of life. Microbes and plant-based bioremediation approaches are some of the sustainable strategies for the biodegradation of harmful pollutants instead of chemical-based treatment ...

Bioaugmentation and Biostimulation

Bioaugmentation and biostimulation are procedures utilized for bioremediation to upgrade the quality of soil and water by utilizing microorganisms, nutrient composition, and development variables. In bioaugmentation, the utilisation of particular diverse sorts of microorganisms for the degradation of poisons, and in the case of Biostimulation ...

Bioaugmentation for enhancing biological wastewater treatment

Biotechnology Advances, 1992
The literature on bioaugmentation products has been reviewed. Their manufacture and method of use is explained. The various applications are listed and the independent investigations, as opposed to manufacturers accounts, at laboratory and full scale are reviewed. The economics and kinetic modelling are also discussed.

Economics and Valuation Of Bioaugmentation

2012
This chapter reviews the costs and benefits of bioaugmentation for treating chlorinated ethenes in groundwater. Detailed cost estimates are provided for a range of template site scenarios to provide practitioners a first estimate of the expected overall costs and the specific cost items involved.

Bioaugmentation as a soil bioremediation approach

Current Opinion in Biotechnology, 1996
The debate over the efficacy of bioaugmentation rages on, with research continuing to demonstrate that its advantages for soil bioremediation are difficult to predict; however, when it works, the results are often very encouraging. The difficulties arise from, among others, the diversity of the microorganisms used, environmental heterogeneity, and ...

Bioaugmentation for Groundwater Remediation

2010
Abstract : The application of bioaugmentation technology has the potential to reduce both the time and cost associated with remediating groundwater contaminated with chlorinated volatile organic compounds (CVOCs), and it has become widely used as an in situ treatment alternative. The primary goals of this field demonstration were to evaluate the amount

Bioaugmentation of Azo Dyes

2010
Biodegradation is a cost-effective method to remove the residues of azo dyes prior to their discharge in wastewater streams from dye product industries. The efficacy of this treatment method is highly dependent on establishing an effective degrader community and maintaining environmental conditions that support the growth and activity of the degrader ...

Bioaugmentation for MTBE Remediation

2012
Bioaugmentation to treat methyl tert-butyl ether (MTBE) in groundwater was considered a promising technique for several years, with several researchers involved in developing and testing MTBE-degrading bacteria. Although the effort yielded important insights into the biodegradation of MTBE and its daughter product tert-butyl alcohol (TBA ...

A bacteria injection scheme for in situ bioaugmentation

Journal of Environmental Science and Health, Part A, 2013
This article presents an innovative design for inoculating the desired organisms to stratified geological layers at desired rates during in-situ bioaugmentation. The new delivery system consists of intermittent porous tubes connected in series with impermeable polyethylene tubes that run horizontally in each stratified layer of a contaminated aquifer ...

Research Needs for Bioaugmentation

2012
Bioaugmentation represents a remarkable success story of applied research, and future research should lead to more successful applications. This chapter provides an introduction to the future potential of bioaugmentation (and bioremediation in general), and seeks to identify the research needs that, if addressed, will help realize this potential. First,
