Waste decomposition is a complex biological process which
requires countless bacterial actions and interactions over time
to be achieved. The bacteria normally present in a waste system
can, in a very real sense, become their own worst enemies.
Microbes responsible for the breakdown of organic substrates in
anaerobic conditions convert sulfur compounds into sulfides. The
sulfur cycle is a critical step in the decomposition of waste as
well as absolutely necessary to the survival of the organisms
themselves. Unfortunately, hydrogen sulfide is released as an
intermediate by-product of their normal metabolism. These
bacteria not only cannot utilize this substance, it is toxic to
them. Even low levels of H2S result in unhealthy
organisms. Their appetites are suppressed, motility slows,
growth and reproduction fall off. High levels of H2S
can reduce biological activity to near zero.
Persnickety® 713 is a carefully selected, precisely
balanced, blend of several bacterial strains chosen for their
striking ability to utilize hydrogen sulfide in their metabolic
process. Essentially, the H2S molecules are oxidized
by Persnickety® 713 to form elemental sulfur. The
sulfur is then stored by the bacteria within cell structures for
later use should H2S become unavailable. This
remarkable process results in dramatic H2S
reductions. Often, dissolved H2S levels drop below 1
part per million (1 ppm). (This level of H2S is
generally agreed to be the threshold limit for odor.) By
maintaining this extremely low H2S level, odor
generation, and the accompanying complaints, cease to be
problematic. The second major benefit derived from the removal
of H2S is a healthy, efficient biomass. The impact
of a highly toxic substance such as H2S varies in
specific effect from system to system. Many of the changes in a
recovering biomass are subtle, some however, can be stunning.
Yes. Persnickety® 713 controls normal domestic
loadings of F.O.G. in two ways. First, while these compounds are
eventually degraded by normally present bacteria, they are
exceptionally stable and require extended time for breakdown.
Persnickety® 713 contains strains which can readily
convert these substrates into more elementary components (i.e.,
proteins, fatty acids, glycerols, CO2, H2O). These simpler
compounds are far more readily available to the normally present
bacteria resulting in faster, more complete reductions.
Secondly, grease buildup is almost always accompanied by
escalating H2S levels. As previously discussed, H2S
inhibits the functions of bacteria and will greatly impede a
process which, without help, is slow at best.
Yes. As mentioned earlier, some of the changes which Persnickety®
713 can bring to a wastewater treatment system are dramatic -
sludge reduction is one of them. Again, H2S
reduction and the synergism produced by and between the
Persnickety® 713 strains and the normally present
bacteria are responsible. In simplified terms, the organic
material available for decomposition is more "food"
than a "sick" biomass can digest. Leftovers settle and
form sludge. The anaerobic conditions that result produce more H2S and a cycle is put into place that is difficult to
break. Fortunately, these conditions are made to order for
Persnickety® 713. Dissolved sulfide levels drop. The
biomass is rejuvenated and populations increase at a tremendous
rate. As the sludge is detoxified it becomes an available food
source and can be reduced.
Since the unique blend of organisms found in Persnickety®
713 is not normally present in the system, it will be
overwhelmed by the constant influx of the bacteria present in
any treatment system. Ongoing inoculation at required levels
provides the proper balance.
Persnickety® 713 is supplied in liquid suspension
and is simply poured or metered into the wastewater stream. This
may be at the head of the plant or, in ponds and lagoons,
wherever maximum dispersion is likely.
Persnickety® 713 is carefully cultured in deep-vat
fermentation tanks. Throughout this process, periodic checks are
made to insure that proper balance is achieved between the
strains in the product. The ratio of the strains to each other
is far more critical to the proper functioning of Persnickety®
713 than is a total count of the bacteria. Other factors, such
as motility, also are of more significance than sheer numbers.
The real questions isn't are there enough bacteria present, but
are the bacteria present right for the task at hand. That
question can only be answered by performance in the field.
Yes. pH is a very important consideration. Extended exposure to
a pH of under 6.0 or over 9.0 can destroy the bacteria. High
concentrations of heavy metals, chlorine, certain solvents, high
levels of biocides or disinfectants, as well as extended
temperatures over 108° F. can kill the bacteria.
