Shearforce Pumps w/ Patented Shearforce Rotors
Shearforce rotors do not have vanes and thus have
specific advantages over conventional impellers
and are better suited for certain
applications. These applications include
entrained gas (air induced fluids), high
viscosity fluids and fluids with high solid
content. The Shearforce pump plays an important
role in the bio-remediation process by pumping
air, solution, and solids, a three phase
solution. The air creates millions of
microscopic droplets and assist with solid
separation from the hydrocarbons. The pumping
action prevents fluids such as oil from
emulsifying.

Treatment of Sludge "IN SITU".
The Problem Crude oil tank bottoms contain
settled inorganic particles which create a very
tacky sludge at the bottom of storage tanks or
when placed into sludge pits.
8
Shearforce Sludge Processing
The use of SFACL (asphalt crude liquefier)
liquefies asphaltenes and paraffin oil without
the need of large amounts of equipment or
personnel. This process turns the sludge into a
pump able and sellable commodity.
9
Shearforce Sludge Processing
The Solution The solution is to inject an
all-natural SFACL biodegradable solvent which is
allowed to penetrate the crude over a 24 hour
period. Once the asphaltic crude is liquefied,
the crude is pumped to a skid tank for screening
where it is stored for off-site
transportation. The Application The Shearforce
Conditioning Process of spraying the chemical
solution into a crude sludge at a very low
pressure. This physical application requires
very simple equipment without high pressure
applications eliminating potential danger to the
operating personnel.
10
Shearforce Sludge Processing
The Effect The picture below shows the
liquefying of the sludge. This application is
designed to create a solids suspended slurry or a
very pumpable sludge that will not stick to the
interior of hoses or downstream containment once
it is removed from a tank.
11
Shearforce Sludge Processing
The Result The now pump able liquid recycled
crude is pumped from the pit into a skid tank for
screening of small debris. Sludge pits can be
cleaned at a rate of 300 m3 per day. The
crude is stored in skid tanks until offsite
transportation is arranged.
12
Shearforce Sludge Processing
The recycled crude has similar characteristics to
number 6 fuel oil with a flash point of 136
degree Fahrenheit. This crude can be blended
with 5 diesel fuel allowing the product to be
stored for long periods of time.
13
Treatment of Sludge IN SITU
OPERATION- Sludge Pits/Oil Storage
Tanks Procedure The sludge will be treated by
spaying the sludge with SF-ACL using a low
pressure pump from a water truck. The SF-ACL is
used at a rate of 6 to 10 of the volume of
sludge to be treated. The SF-ACL will be allowed
to penetrate the sludge for a 24 hour period. A
Vacuum truck or a floatable small barge equipped
with the SF950 pump will be used to pump the now
liquefied sludge into a receiving/filter
tank. The run off will be further cleaned
through the use of additional filter tanks or
through the hydro-cyclone separator. The now
clean fluid will be pumped through a density
separator to separate the water from the now
fuel oil. The fuel oil will be pumped into
tanker trucks for shipment. The oily water and
sludge sand will then be treated with SF1000
using a SF- 1000.
14
Treatment of Sludge IN SITU
OPERATION- CONCLUSION The SF ACL will liquefy
the sludge in less then 24 hours. SF1000 will
reduce the TPH levels of the remaining sand to
less then 1 in 2 hours. EQUIPMENT LIST 1 qty.

Shearforce Sludge Processing
BACKGROUND Bioremediation is the process of
encouraging the natural process of biodegradation
to cleanup spills and other environmental
problems caused by humankinds activities. There
are three different types of bioremediation
nutrient enrichment, seeding with naturally
occurring microorganisms, and seeding with
genetically engineered microorganisms.
Shearforce experience with the cleaning of
drill cuttings in Nigeria using the nutrient
enrichment process of SF-1000 has demonstrated
that there is a diverse enough indigenous
population of oil-degrading microorganisms in the
soil to carry out the bioremediation process.
Populations of oil-degrading microbes in most
environments are limited by the availability of
hydrocarbons. Following an oil spill, this
limitation is overcome and the microbial
population expands. In order for this to occur,
the microbes need oxygen for respiration and
other nutrients that are not available in
petroleum. Oxygen is assured by the use the
Shearforce Pumps which added millions of
microscopic air bubbles by injecting air into the
suction of the pumps.
17
Shearforce Sludge Processing
BACKGROUND Oil provides a rich source of
reduced carbon, but no readily available nitrogen
or phosphorus. These nutrients are vital to the
growth of microbes. Nitrogen is essential for
the synthesis of proteins and nucleic acids and
phosphorus is vital for nucleic acids, and the
energy metabolism of the cell. Some bacteria can
fix nitrogen from the atmosphere, but this is not
widespread in oil-degrading microbes. Thus, the
growth of oil-degrading microorganisms is limited
by the availability of nitrogen and phosphorus.
SF-1000 provides these nutrients assuring the
goal of the bioremediation process.
18
Shearforce Sludge Processing
Land Bioremediation After the heavy sludge has
been removed from an earth pit, a second chemical
SF-1000 is sprayed into the the contaminated soil
to further breakdown the crude. SF-1000 is a
synergistic blend of synthetic surfactants which
emulsify the hydrocarbon contaminants into
microscopic droplets. The emulsion is easily
biodegradable by naturally occurring
micro-organisms (microbes). SF-1000 provides
nutrients which create an immediate stimulation
of the indigenous microbes (bacteria) and provide
an immediate food source when tilled into the
soil. This food source promotes the growth and
metabolic activity of the micro-flora present. A
Track hoe is used to rack in and mix the
hydrocarbon contaminated burns with the oily pit
sludge. The loose debris is placed into the pit
for treatment as compose material.
19
Shearforce Sludge Processing
The Result . Fresh soil is used from the
surrounding area for stabilization material as
well as additional source of indigenous bacteria.
This process produces optimum condition for
natural bioremediation. The land is then
suitable for farming or other use.
20
Shearforce Sludge Processing
Water Bioremediation Oily water will be present
after the oil has been separated from the sand
either from sludge pits or oil spills. The
process of cleaning the oily water is similar to
that of oily soil. SF-1000 is mixed into the the
contaminated water to further breakdown the
crude. The process may be enhanced by the use
of heated water in the case of heavy oil/water
emulsions.
21
Shearforce Sludge Processing
Soil and/or oil samples are collected by a grid
sampling method for an on site TPH analysis.
The TPH level of 200,000 ppm is dramatically
reduced to acceptable levels of 5000 ppm with 24
hours. Further reduction in TPH levels will be
obtained after an additional 48 hours due to the
drying and bio-degradation of the hydrocarbons.
22
Shearforce Sludge Processing
OPERATION-Oily Soil Procedure The soil will be
cleaning by a tilling method using an excavator
or loaded into SF washing tank using a 1 m3
front loader. Once in the washing device SF1000
will be added along with water. The soil will
receive a 20 to 60 minute wash depending on the
background reading of the contaminated soil.
After the washing cycle, the DC will be placed in
a designated DC clean area or removed from sites
using dump trucks for deposit elsewhere. The
SF1000 will be mixed at a ratio of 1 ½ parts of
concentrate to 10 parts water. One and one half
gallons of SF1000 is required for 1 m3.Each wash
is approximately 10 cubic meters of contaminated
media. Before being discharged there will be a
TPH reduction of approximately 93 to 95 upon
completion of the wash cycle. When the media is
discharged, it should be placed in an area for
additional drying and the bio-degradation of the
hydrocarbons will continue without additional
handling. A final analysis will be taken 48
hours upon completion to determine the reduction
in the TPH.
23
Shearforce Sludge Processing
OPERATION- CONCLUSION SF1000 will reduce the
TPH levels to less then 1 in less then 24 to 48
hours while being handled only once. The
bi-product that is left can be used as road base
or sold as materials for brick making. EQUIPMENT

Shearforce Sludge Processing
OPERATION-Oily Water Procedure Flotation
protective oil booms must be laid out to contain
the oil spill and protect from the potential
spreading of the contamination in the
water. Samples of the contaminated water
should be taken to establish back- ground TPH. A
vacuum truck should be utilized to remove as much
free oil as possible, i.e. the oil floating on
the surface. Once as much oil has been removed
for salvage as can be expected then the cleanup
can begin. By using flat bottom boats, two inch
trash pumps fitted with two inch hoses and
fire nozzles, the media can be sprayed with
SF1000. The chemical can be maintained in a
500 gallon tank on the boats. As the chemical is
sprayed there will be an immediate color change
and all rainbows of the oil will dissipate. The
contaminated media (oil water mixture) will
need to be worked towards the booms or land so
that the media can be reduced from spreading.
The media will be pumped through a series of
density separators then into frac tanks. Once in
a frac tank dry ice will be used to further
separate the oil from the water. The oil will
then flow through a weir section to allow the
separated oil to flow out into salvage
tanks. Once the water has been cleaned the
samples should be taken again to confirm the TPH
levels.

Technical Explanation of Chemicals
SF-1000 is a concentrated water based
synergistic blend of biodegradable, non- toxic,
non-flammable nonionic surfactants composed of
Polycxyethylene Ethers - Sodium bis
(2-ethyhexyl) sulfosuccinate - CAS 577-11-7.
Classified as Alkoxylated Alcohols C10-12
ethoxylated propoxylated - CAS
68154-97-2. D.O.T. classification is
non-regulated.  The freight classification is a
non-hazardous cleaning compound. It does not
contain any enzymes or microbes. The surfactant
action of SF-1000 allows it to emulsify
hydrocarbon contaminants into microscopic
droplets suspended in solution. This emulsion
solution remains stable in the rinse and/or
treated media and plays an important role in the
biodegrading of hydrocarbon contaminants since
the emulsion is easily biodegradable by
naturally occurring microorganisms. Thus
SF-1000 represents a food source that promotes
the growth and metabolic activity of the
micro-flora present. The net effect is an
increase in the rate of hydrocarbon
biodegradation. It is this methodology
provides a multitude of benefits when using
Shearforce SF-1000TM for spill response, in-situ
bioremediation, water treatment or cleaning
applications. Because Shearforce SF-1000 is a
non-hazardous, non-flammable, water-soluble
liquid, it can be used for removing oil and
grease on surfaces while providing the following
benefits Will not diminish the integrity of
