RELEVANT FINDINGS OF FACT
Specification
1) The Specification discloses a water purification system
which uses ozone as a disinfectant and includes an ultra-micro-
filtration membrane 170. The ultra-micro-filtration membrane 170
is described as comprising a water container entrance 172 opening
to thousands of vertically extending capillaries 176 which are
permeable to water. (Specification, 11).
2) Water filters out of the capillaries into the central channel
174, while the suspended particles which cause turbidity are
retained inside the capillaries 176. (Specification, 11-12). The
ultra-micro-filtration membrane 170 is thus said to “significantly
reduce the turbidity level” in the water. (Specification, 11).
3) The ozone in the water entering the ultra-micro-filtration
membrane 170 reacts with debris stuck on the capillary surfaces
176 thereby providing a level of self-cleaning to the ultra-micro-
filtration membrane 170 and reducing the remaining concentration
of ozone in the water. (Specification, 12).
4) The Specification states that in order for the self-cleaning
feature to work, the membrane must be resistant to the
ozone/disinfectant. (Specification, 12).
Gastman
5) Gastman relates to a process and transportable apparatus for
the treatment of contaminated water with ozone to produce potable
water. (Abstract, 1).
