WATER PURIFIED BY OZONE
The Successful Plan of Moscow for
keeping Down Infectious
Disease Germs.

A new method of sterlizing a city's
water supply is being successfully OPP
Grated in Russia, and it was described
at the annual meeting OF the .Ameri-
can association of water works en-
gineers in a paper forwarded by
Nicholas Simin, chief engineer of tho
city of Moscow, where the system has
been adopted and according to Mr..
Simin is universally commended, says
the Boston Globe.
The plan is to sterilize the water
by the Introduction of %ozonized air.
and it is contended on its behalf that
it destroys all the bacteria in the
water and makes it at comparatively
small cost absolutely safe for drink
ing purposes.
So far, the system has not been
adopted outside of Russia, but NJ.
Simin contends that in this country
conditions are more favorable than
anywhere else for its adoption, and
he advocates it's Introduction here as
tending to solve all problems in re-
gard to contaminated water supplies.
The system is based upon the prin-
ciples that ozone burns all organic
matter with which it comes into con-
tact in water, including bacteria and
their vital products, that with water
which has been freed previously of
suspended matter the destruction of
the bacteria is equally efficient no
matter how great may be the num-
Der, and that the p%athogenic bacteria
are among the first to be destroyed.
The publication of the water in
this way is simply a development of
and an improvement upon the or
binary aeration of water by means
of atmospheric air. The air, before
coming in contact with the water,
is subjected to a series of electrical
discharges which convert the oxygen
from diatomic oxygen to triatomic
oxygen which is ozone and is remark
able for it's power of oXidizing or
ganic matter including the bacteria
in water. The cost is put at S6.25 for
each 1000, 900 gallons, or in large
plants even less.
Extensive experiments in the sys-
ten have been made in France, Ger
many, Holland and Belgium. The
necessary removal of suspended mat
ter is accomplished by using a small
quantity of coagulant for mere clari-
fication, NJ. Simin says. Domination
oNidizes not only the bacteria, but all
organic matter. The water is rem
dered colorless, sparkling and odor-
less. 1t has an agreeable and re-
freshing taste and there is introduced
: into it no foreign matter except oXy-
2 gen, which, of course, is beneficial.

Nine. Patti would never play in an
opera where anyone had TO sit on a
table. This was because she had not
, made the success in Carmen that she
had in other operas. She attributed
. this entirely to the fact that she had
! to sit on a table in the inn scene in
the second act. Nine. Scalchi was in
a very sad way if she met anyone that
squinted, and she would go through
{ a long lot of %evolutions to rid her.
