Appeal 2006-2816
Application 10/434,125
12) Gastman states that the vessels and conduits that come into
contact with ozonated water should be made of materials which are
resistant to ozone oxidation. (Gastman, col. 15, l. 65-col. 16, l. 4).
13) Gastman discloses that “the system of the invention is
extremely flexible and the process of using the system may be
tailored for a particular contaminated water.” (Gastman, col. 16, ll.
27-29). Gastman contemplates, in particular, bypassing various
vessels in the embodiment shown in Figure 1. (Gastman, col. 16,
ll. 12-47).
Mori
14) Mori discloses a water treatment process in which ozone is
added to raw water and filtered with an ozone-resistant membrane.
(Mori, col. 5, ll. 3-4)
15) Mori teaches that the concentration of ozone in the water is
preferably adjusted to a range of .05 to .3 mg/l. (Mori, claim 1).
16) Mori states that it is known in the art to use ultrafiltration
and microfiltration membranes in small scale water purification
processes because of their advantages over coagulation
sedimentation processes including a high ability to remove
impurities, germs and protozoas sufficiently, high reliability, etc.
(Mori, col. 1, ll. 47-55).
17) Mori teaches that the presence of ozone in the raw water
helps to decompose the organic substances attaching to or clogging
the membrane so that a large filtration flux can be obtained. (Mori,
col. 4, ll. 6-10).
