FlocClays
are bentonite and organoclay based flocculants
in powdered form that remove oils, grease, surfactants,
dyes, inks, coolants, solvents, metals and heavy
metals and suspended solids from wastewater. FlocClays
consist of bentonite, organoclay, and other basic
items that cause encapsulation of oils and greases,
removal of other organics by partition and chemical
bonding, as well as removal of heavy metals by
precipitation, ion exchange and chemical bonding.
The result is a dense non-leachable sludge which
normally passes the TCLP (Toxic Characteristic
Leachate Procedure) test. There exist a wide variety
of blends which can be used to treat numerous
waste streams. |
The entire wastewater treatment process can be
accomplished in one tank, utilizing FlocClay as
a chemical reactant. FlocClay is fully capable
of breaking slight emulsions alone, or in conjunction
with additional chemicals, if required to break
oily emulsions. This procedure can be performed
in the same tank prior to flocculation.
Description
of FlocClay treatment
Typical conventional treatment methods require
the addition of various chemicals to break oily
emulsions, precipitate heavy metals, coagulate,
flocculate and condition sludge. Usually several
steps are necessary, requiring the use of multiple
mixing tanks and additional equipment. It is not
uncommon for this process to take several hours
to accomplish these goals. FlocClay causes flocculation
of contaminants in minutes rather than hours.
Using the FlocClay one step method, the entire
treatment process can be accomplished by the addition
of a small amount of FlocClay directly to the
wastewater stream.
FlocClay powder flocculants are useful for treating
wastewater streams of 50,000 gallons or less per
month. They are able to remove oils, other organics
and heavy metals simultaneously without the need
for pre-treating with acids and salts.

Benefits
of use
FlocClay
powder flocculants have several advantages over
liquid polymers
- They remove oils, other
organics and heavy metals simultaneously.
- They may accomplish removal
of oils and other organics in one step, without
pre-treating with acids and salts (lab testing
is advisable).
- Solid powders produce
a sludge that is easily de-watered and landfilled.
- Filter cakes will pass
TCLP testing if handled properly.
- Most systems require
no more than a 90-second mixing time.

An organoclay-based flocculent. Removes slop oil,
trap oil, motor oil, hydraulic oil, vegetable oils,
synthetic oils and greases, and transformer oil
with PCBs to non-detectable levels. Encourages recycling
of water and allows for zero discharge. Solvents
are also removed to low levels. Requires a 5-minute
mixing time. |

Organoclay-based flocculent that removes anions
such as hexavalent chrome, arsenic, selenite, cyanide
and chlorinated organics such as colors, humic acids,
dyes and inks. Requires a 5-minute mixing time. |
| FlocClay 800, 802 |
Organoclay/activated carbon-based flocculent that
removes oils, greases, surfactants, soaps, detergents,
metals, and volatile organics from wastewater. Used
in car and truck washes, bilge water cleanup, storm
water runoff, laundry wastewater. Requires a 5-minute
mixing time. |
