Introduction
R2000
Groundwater
and aquatic systems receive wastes from numerous sources such as:
- Industrial
Waste Water
- Herbicides
- Pesticides
- Chemical
fertilizer runoff
- Leach ate
from municipal and industrial landfills
- Leaks
and spills from chemical and fuel storage facilities
- Gasoline additive MTBE, & VOC'S
- Drinking Water Wells
- Bio-Chemicals
- Benzene, Toluene, Ethyl
Benzene and Xylene
- All Organic Compounds
- Recycling production water
for reuse
Effective waste management strategies must include an economic means to destroy the
contaminants in aquatic systems.
In recent years, a technique called solar photocatalytic oxidation has proven to be an
economical and robust process for destroying organic contaminants in aquatic systems. Blake has recently compiled a literature survey describing
photocatalysis for the removal of hazardous compounds from water and air and has listed
575 scientific papers describing a variety of applications for the process.
R2000 Solar Oxidation
Facility Operation
The R2000 Solar Oxidation Facility was installed at a
remediation site in Gainesville, Florida in which an underground aquifer was
contaminated with BTEX. The State permit requires that the concentration of
BTEX constituents in the treated wastewater must be below 65 ppb prior to
transferring the treated water back to the environment.
Six photoreactors operating in series were used for this task. The chart
on the left shows the concentration history of the BTEX constituents in the
containment tank. On a cloudy day, in which the average UV intensity is
31W/m2, it is readily seen that after three hours of operation, the
concentration of BTEX in this 500 gallon underground aquifer was brought
down to a negligibly small level (well below the required 65 ppb). These
results clearly demonstrate the efficacy of the solar photocatalytic
oxidation process for destroying organic contaminants. It is a robust and
cost effective process which is applicable to a wide variety of remediation
scenarios.
The technical staff at Clear Water Industries is available to discuss specific
applications and design a modular facility which will meet customer specifications.
Detoxification performance similar to that shown in the attached figure can be achieved
for many industrial effluents and contaminated ground water aquifers with a capacity up to
one million gallons per day.

The row of photoreactors (top picture) and the 500 gallon
storage tank (bottom right picture) are primary components of the R2000 Solar Oxidation Facility. The
R2000 was installed at a remediation site in Gainesville, Florida alongside an active
carbon absorption system (bottom left picture).
After a lengthy
comparative analysis, the R2000 proved to have the superior technology. The R2000
was significantly less expensive to install and it detoxified polluted water better and at
a fraction of the operating cost of the older technology "active carbon absorption
system". Additionally, the R2000 leaves NO TOXIC RESIDUE, thus
no costly environmental dump expense is required.
Advantages of the R2000 Solar Oxidation Facility
- Low energy consumption
The solar photocatalytic oxidation process used to
destroy the aqueous contaminants is driven by solar
ultra violet (UV) radiation, and thus the energy
consumption is very low compared to air stripping and
carbon adsorption
- Less expensive to
fabricate
The solar radiation used to drive the process
is collected with flat panel photo oxidation reactors, which
are simpler to fabricate than concentrating reactors
- The system is modular
so that additional reactors can be added or removed as
needed
- The contaminants are
completely destroyed rather than being transported from
one medium to another as is the case with air stripping or
carbon adsorption
- The facility can be made
portable so that it may be transported from one
remediation site to another
- The facility can be
configured to accommodate a wide range of flow rates:
5 to 5,000 gpm
- Successful system for the
complete eradication of the gasoline additive MTBE, VOC, &
Bio Chemicals
- Recycling water from
processing Plants Odors, Food, Carpet, Fabric,
Pulp&Paper and Pharmaceutical.
- Grey water, for Recycling.
