Bioremediation and Bioaugmentation Services
Bioremediation is the application of a biological treatment, mainly microbes, to the cleanup hazardous contaminants in soil and surface or subsurface waters These microorganisms can be used to transform them to less harmful forms. 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.
Three critical factors in deciding whether bioremediation is the appropriate method for site remediation are:
- Whether or not the contaminants are susceptible to bioremediation by the organisms at the site (or by organisms that could be successfully added to the site).
- Whether or not the contaminants are accessible to the micro-organism (geological considerations may become a factor)
- Whether or not any inhibitory environmental conditions exist that may interfere with the growth and reproduction of these microbes.
Bioaugmentation is a process where selected, standardized bacteria (microbes) are added to an area that has been contaminated with an unwanted substance. These bacteria breakdown the contaminants.
Scientific advances have enabled us to isolate and mass-produce standardized pro-biotic bacteria and fungi into industrial concentrated inoculum's. These selected formulations, of multiple strains of bacteria, can be targeted to address specific contaminants.
Traceable scientific studies for these standardized, CFU count (colony forming units) microbial products have been conducted and demonstrate the efficacy of microbes for the safe remediation of numerous contaminants.
These standardized high CFU count probiotic formulations allows the bioaugmentation process to remediate pollutants and a rate which far exceeds that of natural indigenous microbes (intrinsic bioremediation) and exceeds present oxygenation technology.
Many of the most toxic environmental contaminants are now candidates for bioremediation.
These range from microbes which have a natural affinity towards hydrocarbons to others which, through a primary mechanism of control known as competitive exclusion, limit the presence of pathogenic microorganisms in aquacultural environments. Still others, through biological nutrient removal, reduce the overload of organic matter in water, usually excess nitrogen, ammonia and phosphorous which serves as a food supply for algae, cyanobacteria and certain weeds.
