Biostimulation vs. Bioaugmentation
Bioremediation uses naturally
occurring microorganisms to degrade various types of wastes.
Like all living creatures, microbes need nutrients, carbon, and energy to
survive and multiply. Such
organisms are capable of breaking down chemicals to obtain food and energy,
typically degrading them into harmless substances such as carbon dioxide, water,
salts, and other innocuous products.
Biological treatment techniques fall
into two categories, biostimulation and bioaugmentation.
Biostimulation refers to the addition of specific nutrients to a waste
situation with the hope that the correct, naturally occurring microbes are
present in sufficient numbers and types to break down the waste effectively.
This assumes that every organism needed to accomplish the desired
treatment results is present. But
how can we be certain that those organisms present are the most suitable to
degrade all the materials present? And,
if the naturally occurring organisms present were truly effective in achieving
complete waste breakdown, then why are there problems at sites?
Letís look at an example.
Grease accumulates in sewers and grease traps. Grease is biodegradable and sewers contain a large bacteria
population. Nitrogen and
phosphorous are in ample supply and most sewers are aerobic in nature.
Yet grease accumulates. If
the principle that all the necessary organisms are always present in sufficient
number and type, then grease breakdown should occur in sewers and grease
deposits should be rare.
An alternative approach is to use
bioaugmentation, which is the scientific approach to achieving controlled,
predictable, and programmed biodegradation.
Bioaugmentation involves the addition of specifically formulated
microorganisms to a waste situation. It
is done in conjunction with the development and monitoring of an ideal growth
environment, in which these selected bacteria can live and work.
Bioaugmentation allows one to
control the nature of the biomass. It
ensures that the proper team of microbes is present in the waste situation in
sufficient type, number, and compatibility to attack the waste constituents
effectively and break them down into their most basic compounds.
BioWorld Waste & Odor
Treatment uses a combination of proper bioenhancement compounds and selected,
naturally occurring microorganisms for the complete solution to many waste
problems. The special formulations
we have developed using biotechnology maximize the ability of the microbes to
reproduce and thrive in the waste situation.
The addition of appropriate concentrated microbial blends to handle
specific waste types completes the approach.
BioWorld allows the user to
control the environment where the bacteria live and work.
It allows the remediation process to become a controlled process, which
results in faster treatment times and more complete waste degradation processes.
