XLG first converts the grease into free fatty acids, which are
water soluble, thus reducing accumulations. Further digestion
by the beneficial microbes in Bacta-Pur XLG converts the fatty
acids into carbon dioxide and water. The process continues beyond
the grease trap resulting in cleaner drains downstreams.
What is an enzyme?
A. An enzyme is a protein molecule, which can act as a catalyst
of various biochemical reactions. Enzymes are a fundamental
cellular metabolism; they can also be isolated and used
in many industrial and domestic processes. Enzymatic activity
is very specific. An enzyme, which solubilizes a specific
protein, may not work on another - certainly not on grease.
Q. Can enzymes be used in wastewater treatment?
A. Yes, enzymes can be used to solubilize solids such as
sludge or grease. There are two major classes of enzymes
with respect to wastewater treatment:
- Extracellular enzymes, which are liberated into
the water and are not attached to microbial cells;
- Exoenzymes, which are associated with the exterior
of the microbial cell wall. Exoenzymes are often
more efficient than those not connected to the microbial
Q. Do enzymes work for extended periods of time?
A. No, activity of free enzymes can be quickly depleted.
Beneficial microbes, however, in Bacta-Pur®
biotechnologies have been selected for their ability to
both produce and supply essential biochemical requirements
of enzymes. Enzymes do not reproduce; microbes do.
Q. What are the byproducts of enzymatic activity in grease
A. This depends on the types of quantities of enzymes added.
Theoretically, they have the ability to convert all the
grease into free fatty acids. This rearely occurs, however,
do to depletion of enzymatic activity. If the treatment
is not complete, partially digested grease may leave the
Q. Does the addition of enzymes provide any benefit beyond
clearing the grease trap in the pipes?
A. Not likely, huge amounts of enzymes would have to be
added, to firswt solubilize all of the grease in the grease
trap and still maintain enzymatic activity. A key to any
treatment is cost-effectiveness. Bacta-Pur®
were designed to provide the most cost-effective treatment
not only of grease traps but also of the downstream drain
Q. What is the difference between adding enzymes and
A. Enzymes alone can be rapidly inactivated. Bacta-Pur®
XLG provides microbes, which are not only enzyme factories,
but the exoenzymes produced by the beneficial microbes are
reactivated by the living cells. Furthermore, the grease
and sludge digesting ability of the Bacta-Pur®
microbes continue beyond the grease trap to clean pipes
Q. Can Bacta-Pur decrease
methane or hydrogen sulfide in drains and sewers?
A. Yes, absolutely, Bacta-Pur®
biotechnologies actually reduce methane and hydrogen sulfide.
Methane and sulfides are produced by microboes, which can
grow only in the complete absence of oxygen; they can actually
be harmed or even killed by oxygen; they can actually be
harmed or even killed by oxygen. This occurs in sewers,
principally in grease and sludge accumulations, rather than
in the water (particularly for methane). Regular use of
removes the grease and sludge accumulations thus removing
the habitat of the trouble causing microorganisms. In addition
to this, removal of scum and grease from the surface of
the water brings the water into contact with the air and
allows greater diffusion of oxygen into the water. This
accomplishes two additional tasks:
- The oxygen accelerates biodegradation of soluble wastes
into carbon dioxide and water.
- The oxygen also raises the redox potential, thus inhibiting
the production of both methane and hydrogen sulfide.
Furthermore, regular use of Bacta-Pur®
such as with a Bacta-Pur®
the wastewater with the highest concentration of beneficial
microbes, which have no ability to produce methane. Recent
studies as reported in the literature, have shown that bacterial
augmentation can reduce undesirable microbes (e.g., odor causing
strains and pathogens) in aquatic systems by the combined
pressures of predation and addition of high concentrations
of beneficial strains. Bacta-Pur®
biotechnologies were developed to provide at least 10 cells/ml.
Regular additions provide the high numbers of beneficial microbes.
Q. What are the byproducts of treatment with Bacta-Pur®
XLG in the grease traps?
Q. Does use of Bacta-Pur®
decrease the fat and grease leaving a grease trap?
A. Yes, fat, oil and grease (FOG) content of wastewater is measured
by extracting the FOGs from the water using a solvent such as
chloroform/methanol. The solvent is mixed with the wastewater
and then allowed to separate into phases: the solvent phase
containing the FOGs and the water phase. The solvent is evaporated
leaving the FOGs, which are then often quantified by weighing.
The first step of the treatment with Bacta-Pur®
XLG converts the FOGs into smaller molecules called free fatty
acids, which are water soluble and no longer part of the FOGs.
Thus, the wastewater leaving the grease traps contains reduced
fat, oil and grease.
Q. Can free fatty acids produced by treatment with Bacta-Pur®
block pipes down stream?
A. Absolutely not. Free fatty acids are water soluble so they
cannot stick to the walls of a drain or sewer with their turbulent
Q. I have tried adding bacterial products to my grease trap
- even products with times dosing pumps - but it was a waste
of money. Nothing consistently worked. How is a Bacta-Pur®
A. There are many products on the market, but they are virtually
all only containers of dormant cultures. Many hours are required
before the cultures wake up. First of all, the retention time
of water, in a grease trap, is very short; additions of dormant
cultures result in microbes leaving the drap before they even
wake up. Secondly, kitchen operation results in intermittent
addition of very hot water and/or multiple disinfectants entering
the trap. A Bacta-Pur®
is an on-site growing system, which overcomes both of
these problems. A continuous supply of active cultures is added
to the grease trap 24 hours per day. The cultures enter the
system in an optimal physiological condition to clean the trap
and drains, and the continuous additions provide constant reinocultation
to overcome loss of colonies due to the disinfectants and hot
Q. I have added various products to my grease trap, which
have reduced grease, but my drains still keep backing up and
smell of putrefaction. Will a Bacta-Pur®
help me with these headaches?
A. Yes. The benefits of using a Bacta-Pur®
are not limited to the grease trap. The beneficial microbes
continue to work downstream removing grease, cleaning pipes
biologically, and improving water flow.
Q. Do all bacteria produce enzymes to solubilize sludge?
What happens to solubilized pollutants?
A. Not all bacteria produce exoenzymes nor extracellular enzymes
capable of solubilizing grease and sludge. Pollutants which
are solubilized, by the enzyme producing bacteria, are used
not only by these microorganisms, but also by ones which do
not produce the enzymes. This is the concept of water purification
by a balanced community.
