Cabsorb SOS 820 "Super
formally Super Soaker,
is a granular, sorbent product consisting of
calcinated diatomaceous earth particles. The product has very high surface area per pound
due to the three-dimensional, tetrahedral crystalline structures that form the matrix for
the granular, amorphous particles. These hydrophobic granules have efficient filtration
and sorption properties for removing low to trace quantities of hydrocarbons (TPH) and/or
organic pollutants in groundwater or wastewater. The granules will float on the surface of
water to remove light density hydrocarbons or organic residues at the surface or are used
as filtration/sorption bed material (analogous to activated carbon) in tanks or vessels.
The Cabsorb SOS 820 "Super Organic Soaker" sorption capacity for removing petroleum
hydrocarbons from water is estimated be 50% by weight, where the product bulk
weight is about 25 lb.ft3. The three-dimensional structure translates to
ultra-high surface sorption area per pound (approximately 500 m2/gm with
>50% void space) of product available for removing TPH and/or organic pollutants.
"spent" Cabsorb SOS 820 "Super Organic Soaker" contaminated with TPH and/or RCRA organics
can be converted to non-hazardous, Class II industrial solids waste via: 1) stabilizing
with ChemSorb-500 powder or comparable agent to pass EPA TCLP (EPA 1311) and Paint Filter
Test (9095); 2) biological treatment in a bioreactor: or 3) kiln heat processed to form
Treatment of floating light oils, hydrocarbons
The light density, porous Cabsorb SOS 820 "Super Organic
Soaker" granules will float on the
surface of water and remove TPH oil films, residues and surface globules. Applications
include equalization tanks, water storage tanks, chemical mixing tanks, clarifiers,
mud-tanks, sedimentation tanks and holding ponds. The Cabsorb SOS 820 "Super
Organic Soaker" granules should be
dispensed on the surface and remain for one to two hours. The granules can then be removed
via screening or skimming and collected in a plastic bucket or drum. "Spent"
granules can be stabilized by adding eight to ten percent (v/v) ChemSorb-500 powder,
mixing and allowing to air dry in order to pass the EPA Paint Filter Test (EPA 9095) and TCLP (EPA 1311).
TPH sorption filter for industrial wastewater or groundwater
Trace petroleum hydrocarbons in industrial wastewater and groundwater
are a problem for POTW and NPDES discharge permit sites and compromise water resource
management options. A Cabsorb SOS 820 "Super Organic Soaker" "deep bed" can be used upstream to activated
carbon, ion-exchange and heavy metals sorption beds to efficiently remove (i.e. absorb)
the TPH to the EPA Drinking Water Standard. The lower cost per pound and higher porosity,
sorption capacity per cubic foot make this product market competitive.
Boiler condensate water "polishing" of trace
Not infrequently, trace hydrocarbons contaminate boiler condensate
lines, compromising the condensate water quality and reducing ion exchange bed
performance. The Cabsorb SOS 820 "Super Organic Soaker" and/or EC-100 granular organoclay products are
cost-effective sorption filters capable of operating at 150o -> 200oF
at low to moderate psi conditions. Generally, deep-bed pressure vessels with down flow
fluidics are used with average bed residence time of seven and ten minutes for
Cabsorb SOS 820 "Super Organic Soaker" (350 gallons/bed at 50 gpm) and EC-100 granular organoclay (e.g., 50 gallons/bed at
50 gpm) respectively. Operation pressures are zero to 25 psi.
Holding pond or lagoon hydrocarbon water treatment
Water collection, containment lagoons for parking areas, commercial
building and industrial plants are contaminated with oils, trace organics, trace heavy
metals and a wide range of particles and grit. This leachate and runoff water can be
pumped to a bulk storage tank or directly treated (absorbed) using a pump, filtration
module and Cabsorb SOS 820 "Super Organic Soaker" sorption beds to remove the petroleum hydrocarbons and residual
organics. Typically, a seven to eight minute residence time is adequate for
Cabsorb SOS 820 "Super Organic Soaker".
[Alternatively, a Cabsorb SOS 820 "Super Organic Soaker" bed could be employed followed by EC-100 granular organoclay or activated carbon beds].
Car wash and truck hydrocleaning wastewater filtration
Automobile pressure washing and truck hydrocleaning facilities generate
wastewater with dirt, grit, sand, detergents, chemical inhibitors/biocides that is
collected in sumps or bulk storage tanks. Silica and salt concentrations can build-up if
not removed prior to water reuse and result in residue spots on the car and truck
surfaces. To lower operational costs and maintain water quality for treated and recycled
water, FFT has developed an economical, skid-mounted water treatment system for car and
truck cleaning wastewater. The innovative system offers superior performance at reduced
operational cost based on use of a backwash filter in like of cartridge or bag filters,
proprietary chemicals (i.e., ChemSorb-500 and Cabsorb SOS 820 "Super Organic
Soaker" ), and advanced design
nanofiltration unit for removal of silica and salts. Systems are available for 10 gpm and
higher with >90% water recovery.
Boat and recreational vehicle cleanup of light oil, gas and
diesel fuel spills
Cabsorb SOS 820 "Super Organic Soaker" granules provide a safe, easy method for cleanup of oil
spills and bilge discharges. The porous hydrophobic granules rapidly soak-up the oil,
allowing discharge of the water. Light oil contaminated water collected in buckets, pails,
drums, tanks or boat bilges can be easily treated by stirring the granules into the
oil/water, allowing 30 - 60 minutes soaking time, then collecting the "spent"
granules in a bucket or drum. In order to render the sold wastes non-hazardous,
ChemSorb-500 powder can be mixed with the "spent" granules and air dried
(requires several days) prior to disposal.
Ship and Navy vessel bilge discharge water treatment
Routine tanker and Navy ship maintenance generates a substantial volume
of bilge wastewater containing TPH, trace solvents, heavy metals, grit and metal
particles. Once wastewater is collected in a bulk storage tank (or mixing tank), it can be
batch or continuous mode treated through the four stage process consisting of Stage I.
ChemSorb-500 sorption/flocculation, Stage II, Solids Separation, State III.
Microfiltration, and Stage IV. Cabsorb SOS 820 "Super Organic Soaker" (with optional EC-100 granular organoclay)
polishing of hydrocarbons.
Oil tanker ballast water filtration
Ballast water pumped into empty oil (or refinery product) storage
holding compartments to stabilize the vessel becomes contaminated with hydrocarbons. The
Cabsorb SOS 820 "Super Organic Soaker" sorption product provides an economical alternative for rapid filtration
prior to ballast discharge. Importantly, the product can be kiln or biologically treated
and reused to reduce the disposal costs, or used as an expendable bed.
Produced water from oil production
Offshore oil rigs and land-based oil drilling operations are under
regulatory compliance mandates to meet discharge compliance limits for produced water. The
chemistry of produced water is complex due to chemical heterogeneity and thermal and
pressure changes that occur during and following oil extraction and separation.
Cabsorb SOS 820 "Super Organic Soaker" can be used downstream from an oil-water separator and cross-flow or other
filtration equipment to efficiently reduce TPH to meet discharge compliance. At 150 gpm
produced water flow rate, two Cabsorb SOS 820 "Super Organic Soaker" filter beds (150 cubic feet each) would be used
or three beds 75 - 80 cubic feet each). Spent granules could be stabilized to pass the EPA
Paint Filter Test (EPA 9095) and EPA TCLP (EPA 1311) for inexpensive disposal or the
granules processed and reused.
