verted from a murky, conta
minated condition to clear,
pure drinking water. In this
process, such chemicals are
added as lime to control aci
dity; alum as a flocculating
agent which helps remove the
solids by combining them; car
l>on —‘ to remove tastes and
odors; calgon for corrosion
control; and chlorine, which is
added at the beginning and
at the end of the process to
purify the water.
It takes about two hours and
20 minutes to convert dirty
water to pure water, accord

ISOTOX
Seed Treater (F)
Good hybrid seed corn is expensive, so it doesn’t
make sense to plant it without protecting it from
insects and soil disease.
That’s why we’re telling our customers to use
ISOTOX 25 Seed Treater (F). You mix it with
the seed right in the planter box, and your corn
seed goes into the soil with all-round protection.
That’s because ISOTOX is an insecticide and a
fungicide. It works on insects like wireworms,
seed corn maggots and seed corn beetles, and
keeps off dry rot and damp-off.

Industrial Water
Much of the Arm’s indus
trial water comes from a 60-
mllllon-gallon-capaclty 'm 111
pond fed by Back Creek. A
diversion dam on Back
Creek was comple'ed last
year. By siphoning water
from the pond, the main
flow of the creek is diverted
around the plant and mine at
the rate of GOO gallons per
minute through submerged
pipes into the large central
mill pond; the overflow from
the pond continues Back
Creek. By diverting the wa
ter around Us facilities in
this way, the company elim

ISOTOX is made for hy
brids, and it’s made so the
right amount sticks on
every seed. It runs just
about 16c an acre to use
this seed treater so why
take a chance on losing any
expensive seed, or having
to replant later. See us for

of Bock Creek flooding the

Water uncovered in the
course of the "mining opera
tion from underground
streams is pumped out’ at
800-1000 gallons per minute.
This Joins with the indus
trial waste water, from which
the solids have been remov
ed, and is recirculated to the
mill and pellet plants.
HANDLING WASTE WATER
Wastes are divided into
two categories at Grace Mine,
and each is handled separ
ately. These are domestic and
industrial wastes
Domestic
Domestic waste is carried
through soil pipes to a spe
cial flume (channel) where
the flow is measiued, then
into an aferation tank. From
the tank it flows into an aero
accelerator for clearing; then
the effluent travels to a “dos
ing tank”; to slow, sand fil
ter beds; to a chlorine con
tact chamber—and finally,
RECIRCULATING SUMP after solids 'are removed from industrial waste
water, the water is recirculated through this sump and returned to the plant for
use. Ground water pumped from the Grace Mine also passes through this sump.
Any overflow runs into the mill pond for future use. L. F. Photo

the water is discharged In
purified form Ito the; mill

Creek at an average rate of
50 gallons per •minute.
Industrial
Industrial wastes Involve a
far greater volume, but less
complicated treatment.
The main contaminant In
the industrial waste water is
“tailings,” the fine stone res
idues from the milling and
pelleting processes. This ma
terial Is washed through a
collecting sump, and distribut
ed through two, 200 j foot-
Ipng clarifiers. In the process,
most of the solids settle out.
The clear effluent is chan
neled to a second sump and
is recirculated for use in the
plant and mill. Water from
the mine also comes Into the
lecirculating sump and be
comes usable.
The solids, mentioned
above, make up 10-15 per
cent of the industrial waste
water. They collect in two.

Urge, round nettling op
thickening tanks, Long ro
tating “rakes" continually
sweep the solids toward the
center of the tank. From
there, they drop through a
hole, and ari> transported to
the tailings sump; and then
the material (now 2 3-30 per
cent solids) is washed
through three miles of pipe
t 0 the tailings dam where it
is discharged into a huge
earthen holding basin.
Water In this basin dis
charges by seepage and

the rate of 500 gallons per
