TERRE KLEEN™
Inclined-Plate Hydrodynamic Separator
Terre Kleen™ (Patent # US 6,676,832 B2)
is a new product developed exclusively by Terre Hill Concrete
Products designed to clean stormwater runoff as mandated
by EPA under the “National
Pollutant Discharge Elimination System – Regulations for Revision
of the Water Pollution Control Program Addressing Storm Water
Discharges” of the Clean Water Act (CWA).
Terre Kleen™ uses the concept of inclined
plates, based on proven, field-tested technology found in
the water industry. Terre Kleen™ removes suspended solids from stormwater runoff in collection
systems. View Terre Kleen™ Fact Sheets
for detailed information.

the paper titled "RESEARCH
AND DEVELOPMENT OF EFFECTIVE SUSPENDED SOLIDS REMOVAL FROM
STORMWATER RUNOFF IN COLLECTION SYSTEMS USING IN-LINE LAMELLA
PLATE SEPARATORS" presented at the 2003 Pennsylvania
Stormwater Management Symposium held at Villanova University,
Villanova, PA.
THE
PROBLEM
Our waterways are polluted
Today,
particularly in urban areas, a high concentration of pollutants
is found in storm-water discharges. Pollutants from concentrated
human activity settle on impervious surfaces such as streets,
parking areas, driveways and sidewalks until a storm-water
event washes them, untreated, into a nearby drainage. Typically
these inlets eventually discharge into nearby streams, thereby
polluting the environment.
Recent
environmental studies show that urban and suburban storm-water
runoff affects 13% of impaired rivers, 21% of impaired lakes
and 45% of impaired estuaries with untreated pollutants such
as particulate bound heavy metals (zinc, lead, cooper and
chromium), pesticides, fertilizers, oils, litter, grit, other
debris and sediment.
THE
SOLUTION
Terre Kleen™ removes sediment from stormwater
Sediment removal = pollutant removal
The Terre Kleen™ patented technology
is adapted from proven and field tested water cleaning techniques
that have been used by the potable water industry for decades.
This technology can remove sediment as small as 15 microns
from storm water run off, depending on regulatory and cost
requirements.
Once removed
= always removed
Stored sediment
will not be scoured from the secondary chamber during future
storms. After removal from stormwater, sediment is
contained in the primary and secondary chambers ready for
extraction using a vacuum truck. Captured sediment is
then properly disposed .
Stacked inclined plates = smaller footprint
The patented Terre Kleen™ design takes advantage of inclined plates which pack
a lot of settling area into a small footprint. This
is contained inside a precast structure that is designed to
withstand traffic loading....highway, trains or even airplanes.
This allows for optimum utilization of the site.
Precast Concrete Structure = quick installation time
The Terre-Kleen ™
unit is installed into a precast structure at our manufacturing
facilities. When it arrives to the jobsite, it is picked
up like any other precast unit or pipe and placed in the ground.
No special effort, knowledge or training is required by the
installation crew to install a Terre Kleen™.
TESTING
AND VERIFICATION
Testing
and verification of Terre-Kleen's™ performance is being established
by Pennsylvania State University - Harrisburg, under the leadership
of Dr. Shirley Clark, using the testing protocols established
by the EPA’s
Environmental Technology Verification (ETV) Program. The
ETV program, established in 1995 by EPA, is recognized nationally
as the third party verification program that provides objective,
quality-assured performance data on new technologies.
