A NEW INNOVATIVE
MESOPOROUS
NANOSTRUCTURED
MATERIAL
ECAM® (REactive CArbon Material) is a new mesoporous
nanostructured carbon, that exploits the special characteristics
of graphenes, having extraordinary properties in terms of
reactivity and crystallinity, with excellent results proved for recalcitrant
compounds removal from wastewater that place it on the market
as a unique product of its kind and extremely interesting for use in
environmental and energy fields.
RECAM® has been invented by Ing. Ivano Aglietto and industrially
developed by SA Envitech which is the brand owner and the first world
producer of bulk quantities of nanostructured material for industrial
purposes. The RECAM® base structure comprises graphene planes that
are modelled and inclined during the production process to form a
structure with regular cells and channels, providing the material with
special electricity-conduction and absorption properties.
RECAM® is not a mixture of graphene planes, but a mesoporous
nanostructure with a high specific surface area, with sloping polyhedrons,
the sides of which comprise multi-layer graphene planes.
“ To d a t e , R E C A M ® i s t h e f i r s t a n d o n l y
nanostructured material on the market that
exploits graphene’s special properties and is
produced on an industrial scale.”

RECAM® is hydrophobic, inert, non-flammable, completely stable, and
has no negative impacts on the environment. As it is inert, it passed all
the toxicity tests established by the Italian Ministry
of the Environment. No solvents, no heavy metals
and no traces of other toxic compounds are present
within RECAM®, even in ppb. RECAM®’s efficiency
and compatibility with the environment have been
certified by the Italian Ministry of the Environment
and CNR (National Research Center).
RECAM® is a nanostructured material. Nanofibres, multi-walled carbon
nanotubes and other nanoparticles which are integrated in some specific
grades of RECAM® are not free to move, in fact they are blocked inside
the cells of the nanostructured material. The medium size of RECAM®
powder is around a few microns, not a nanomaterial, thus, no potential
risks are observable.
RECAM® can be be used for different kind of applications, like listed
in the following picture. Currently SA Envitech has developed the
first patented industrial applications for water treatment, wastewater
treatment and gas filtration. New upcoming applications of RECAM® are
expected in the near future in particular for soil remediation and for
DSSCs solar cells.

WATER AND
WASTEWATER
TREATMENT PROCESSES
®
WITH RECAM
“The treatment processes based on the use of RECAM® are a new,
ground-breaking approach in the water purification technology
scenario.”
The pocesses differ from traditional treatment technologies due to their high capacity rate for
removing a wide range of contaminants, the reduced investment and running costs, the lack of
sludge production and the simple configuration of plants, which can be sized according to the
amount of water to be treated and the concentrations to be achieved at discharge.
The water and wastewater treatment processes developed with RECAM® are:
filtration, electroxidation, nano Fenton, sonolysis and photocatalysis.
All the processes are subject to international patents and are SA Envitech’s property.
Main benefits are:
•
•
•
•
•
possible to treat almost every kind of wastewater and a wide range of contaminants;
no sludge production;
system configuration that is both simple to build and modular;
low investment costs;
chemicals used only for pH corrections.

n the filtration pocess, RECAM® is the filtering material, while in other advanced
oxidation processes, RECAM® acts as the reaction catalyst, allowing an increase in
the reaction kinetics. The special regular cell structures comprising graphene planes
and the presence of nano-crystals inside them provide RECAM® with unique features in
terms of removal of a wide range of contaminants, particularly of recalcitrant compounds.
During the contact and filtration process between the contaminants and RECAM® there is
no chemical reaction or transformation. There is therefore no risk of unwanted reaction
from by-products or other contaminants that were not present in the original water.
The ability to remove organic compounds, cations and anions at the same time makes
this new filtering material unique in its kind. The RECAM® filtration plants are simple to
construct, modular and do not require high pressure. They work within a range of 0.2÷0.7
bar, as well as by gravity, thus requiring no pumps and may work without consuming
energy, when necessary.
The RECAM® filtration process is especially
recommended for:
• removal of microorganisms, bactericidal
and bacteriostatic
disinfection of water
• high removal rate of light and
heavy hydrocarbons
• removal of organic
substances with high
reduction levels of COD
• removal of PAH, PCB and
BTEX
• removal of MTBE,
guaranteeing values
<1 µg/l
• removal of arsenic,
cadmium, hexavalent
chromium, cyanides,
boron, iron, zinc, manganese and
manganese, atrazine
• treatment of water contaminated by chlorinated solvents
• entrapment of asbestos fibres.
As RECAM is a stable, inert material, no hazardous substances are released into the water
and no by-products are produced.
Unlike other drinking water treatments, such as reverse osmosis, for example, which
produces almost totally demineralised water, RECAM® does not alter the content of
compounds that are precious for our metabolism, such as calcium or sodium: these
elements, essential for human health, remain in the water and are assimilated by our bodies.

ADVANCED OXIDATION
PROCESSES WITH
®
RECAM
dvanced oxidation processes (AOPs) are those processes which are based on
production and utilization of hydroxyl radicals. AOPs have considerable similarities
due to the participation of hydroxyl radicals in most mechanisms that are operative
during the reaction. Hydroxyl radicals are extremely unstable and reactive because of their
high oxidation potential. Since the reactions between hydroxyl radicals and organic species
are extremely fast and nonspecific, these reactions are almost always controlled by the mass
transfer of hydroxyl radical to the organic species or production of hydroxyl radicals. The
kinetics is first order with respect to hydroxyl radical concentration and to the pollutant.
Kinetic constants are in the range of 108÷1010 M-1 s-1, whereas radical concentration, even
in steady state, in these processes is between 10-12 and 10-10 M. Therefore, the pseudo first
order constant is in the range of 10-4÷0.1 s-1.
Given that the hydroxyl radical is such an unstable and reactive species, it must be generated
continuously ‘‘in situ” through chemical or photochemical or sonochemical reactions.
“The use of RECAM® for AOPs give the possibility to use these
processes in a cost-effective manner, without limitation in terms
of organic contaminants removal.”
The application of RECAM®, enables to emphasize and fully develop the benefits of
advanced oxidation and contaminants absorption processes, reaching levels of efficiency
and economy much higher than traditional water purification approaches.

T
here are many lessons one can
learn from the Exxon Valdez oil spill
in 1989 and the recent disaster in
Gulf of Mexico. To summarize, effects on the
ecosystem mainly concerned the intertidal
zone with seabird and marine mammal
populations. One of the frequently asked
questions concerning is: “How many animals
were killed?” No one is able to answer
this question. Eight weeks after BP’s well
ruptured, the impact on marine life became
increasingly visible with images of dead
or dying hermit crabs and brown pelicans
trapped and weighed down in dark syrupy
oil while spawning Atlantic bluefin tuna are
threatened in the Gulf of Mexico – only one
of the two places in the world where they
can reproduce themselves. Fresh rows broke
out after it became public that endangered
sea turtles and other marine creatures were
corralled into 500 square-mile “burn fields”
and burnt alive in operations intended to
contain the oil.
Concerns regarding public health risks and
long-term impacts on the food chain in the
Gulf of Mexico where one-third of the water,
or 78,264 square miles, have been closed to
fishing, are growing.
The technologies usually applied for
remediation and containment of oil spills
present several critical points and are not
effective at all for many situation. RECAM®
can be used both like a barrier system
and for oil removal from sea water. In the
case of a barrier, it is sufficient to spread
the material on the water surface for it to
start to form a uniform and homogeneous
barrier which does not let hydrocarbons go
through. On the contrary, it starts to attract
the oil towards the barrier. In a second
phase, it is possible to spread RECAM® on
the water surface and start to recover the
oil with a process that it is not a simple
sorption process, but an action of capturing
the oil inside the nanostructured material.

THE scientific
ARTICLE
Once RECAM® detains the oil, there are no risks for the oil to be released in the water or in the environment because
RECAM® does not only absorb oil but it entraps hydrocarbons inside its nanostructure. Once the oil is trapped there
is no way for it to be released. This phenomenon is possible thanks to the affinity of RECAM® towards non polar
compounds and its hydrophobic behavior.
In order to recover oil which is not floating on the sea surface but in depth, it is possible to inject RECAM® material
from the deep water. Indeed, it starts to attract the oil and encloses it, then slowly rises to the surface of the water,
with the trapped hydrocarbons, where they can easily be recovered. It is possible to recover RECAM® with an easy
and fast way, just by using nets.
RECAM® material can be burnt with the oil recovered. During the combustion process, no toxic gases are released
because RECAM® is completely inert and it is not infflammable. Hydrocarbons are burnt providing an energy
production and RECAM® can then be used again to recover oil.
“RECAM® is unique both in terms of efficiency in hydrocarbons removal and in
terms of being eco-friendly, particularly when compared to other products It does
not produce waste and is regenerable.”
RECAM® may be regenerated and the crude oil is recovered without any traces
of water. It is also important to emphasize that RECAM® is more effective for
heavy oils and crude oil than for light hydrocarbons. This is an important
difference if compared with other products available on the market.
In the table below RECAM® is compared to other products available for oil
spill remediation.
