As a sorbent and water filtration agent HRCM exceeds the capabilities
of all known water purification systems. After a single filtration
the opacity decreases by a factor of 25-60 and the amount of
suspended particles drops by a factor of 10-30. The filtration
system consistently removes sulphates, sulphides, fluorides,
chlorides, nitrites, iron, zinc, copper, aluminum, manganese,
lead, arsenic, molybdenum and free chlorine. HRCM can purify
hot water and even steam.
HRCM demonstrates a very important and unique property: after
passing through the layer of HRCM 10-15 cm thick the biochemical
oxygen demand of the water decreases by a factor of 2. This
ability allows HRCM to successfully clean water from natural
sources (rivers, lakes and swamps) and make it drinkable.
HRCM is able to remove microorganisms (bacteria and viruses)
from water during the filtration process. Bacteria and viruses
always attach themselves to tiny particles suspended in the
water. Since HRCM effectively captures even the smallest suspended
particles, the bacteria and viruses are also captured and trapped
in the volume of HRCM. To prevent the reproduction of microorganisms
inside HRCM volume HRCM surface can be coated with nano-size
particles of silver and iodine.

HRCM
is a dark grey very lightweight powder that has an extremely large
specific surface area (2,500 m2 per 1 gram of HRCM). The surface
of this material consists of atomic layers of cyclic carbon (graphenes)
with damaged molecular bonds. HRCM also contains about 20% of
tubular nano-carbon structures that are 50,000 times thinner than
a human hair. HRCM is a chemically inert substance, electro conductive,
hydrophobic (limiting wetting angle is more than 90 degrees),
stable in corrosive environments and ecologically clean. HRCM
consists of 99.4% pure carbon materials with a bulk density of
0.01-0.001 g/cm3 (depending on the manufacturing method).
