Bioaugmentation of treatment wetlands – A review

Science of The Total Environment, 2021
Bioaugmentation in the form of artificial mycorrhization of plant roots and bacterial inoculation has been successfully implemented in several fields including soil remediation or activated sludge treatment. Likewise, bioaugmentation seems a promising approach to improve the functioning of treatment wetlands, considering that natural mycorrhization has

Bioaugmentation for Pollutant Removal

2023
Environmental pollution management through conventional methods in the wake of new, recalcitrant, and increasing pollutant loads are no longer adequate or sustainable. Bioaugmentation for pollutant removal is an environmental (water and soil) decontamination approach alternative to the popular and traditional physico.chemical methods.

Ecological study of a bioaugmentation failure

Environmental Microbiology, 2000
A nitrifying sequencing batch reactor was inoculated twice with the aerobic denitrifying bacterium Microvirgula aerodenitrificans and fed with acetate. No improvement was obtained on nitrogen removal. The second more massive inoculation was even followed by a nitrification breakdown, while at

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.

Bioaugmentation of oil-contaminated soils

АгроЭкоИнфо, 2023
In a field experiment, the high efficiency of the in situ bioaugmentation method was demonstrated using three biological products (Putidoil, Arkoil and Multibak Asset) to clean up the territory in the Volgograd region 6 years after an emergency oil spill.

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 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 for nitrification at cold temperatures

Water Research, 2004
Bioaugmentation of nitrifying bacteria for short solids retention time (short-SRT) nitrification is an attractive alternative for wastewater treatment plants in cold climates or for those in the process of upgrading to include nitrification. One possible source of ammonia for the production of nitrifying bacteria is the liquor generated during the ...

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 ...
