Champion Fibre Company are
Making a Great Saving in
Their Wastes.
TO BUILD $750,oOo PLANT

Half of the Total Waste of Two
Years Ago Has Already Been
Stopped and Improvements are
Planned to Reduce it Further.
The Champion Fibre Company is
making every effort to stop the pollu-
ton of the Pigeon river which is car
rying it's black waters into the French
Broad and the Tennessee rivers. The
matter was recently up before the state
legislature and then Governor Hooper
granted an extension of time in the
matter following report by DR.. Dab
ney in which he stated that every eff
fort was being made to utilize the
chemical waste in the manufacture of
by-products. Just what the Cham
pion Fibre Company is doing IS shown
in the following report:
The waste liquors and materials of
this plant are classified and separated
according as they come from the Soda
Process Mill, the Sulphite Process
Mill, the Tannic Extract Plant, and
the Bleaching Process.
l. THE SODA PROCESS MILL. The
reduction of the amount of soda and of
organic matter in the wash waters
going to sewer and in the water of
condensation from the evaporators has
now been completely accomplished by
the installation of new evaporation of
100000 gallons capacity. This efficient
machine and accessories, from the
Zaremba Company, cost in the
neighborhood of $50 100000. In evidence
of the extent to which this installation
is successful, it is only necessary to
state that, just prior to the starting up
of this machine, the entrainment Losses
of soda to the river were 80 of the
total soda used, while after the machine
was put in operation the chemical
analysis showed no losses whatever
from this source.
In the cousticizing department, new
steel tanks for the storage of liquors
and new causticizing cells have been
installed, which were intended to, and
do, in fact, reduce the amount of soda
lett in the caustic sludge. This improve
ment cost in the neighborhood of IS,
10000.
Through these measures the soda
wasted into the river has been reduced
1917 over the conditions existing during
! the first two years of the operation of
the mill. Thus one element of objection
able waste has been practically ELI
minated.
In the retaining department, for
the more complete elimination of
oganic matter and soda from black ash
waste, an additional rotary incinerator
and two additional teaching cells have
been installed at cost approximately
S., 10000, and we are now conducting a
series of experiments looking to burn
ing this material in our furnaces. This
experimental work is being pushed
along vigorously and should be COM
pleted within the next few weeks. 1t is
expected soon, thus, to take care of
this black ash, which, though perfectly
harmless, has discolored the water of
/ the river.
The calcium carbonate waste, as we
are now endeavoring to utilize for
agricultural purposes by the use of a
recently purchased rotary dryer, the
installation of which we expect to
complete in about sixty days.
Practically all the waste from this
will, thus, in time be taken care of.
III. THE SULPHITE PROCESS MILL.
For the elimination of any traces of
So2 from the waste liquors, we have
installed and are now using recently
developed device, known as "Side re
| lief retainer" Evidence of its value
in this direction is shown by the fact
that since its installation we have in
creased the per cent of So2 in the cook
ing liquors by 25%. The whole of this
increase has come from liquors. which
| i'm most SuIphite mills are wasted tn
sewer with their So2 contain still in
them.
Within the past two months we
have started up new white watern
system'which, by the use OF the waste
Il
