Q:
How do Bright Dyes water tracing products
work?
A: Bright Dyes act as a
coloring label on each drop of water. As that water
or liquid travels, it can be identified at each
point on its travel, until it reaches extreme
dilution.
Bright Dyes selectively
absorb light in the visible range of the spectrum.
They are fluorescent because, upon absorbing light,
they instantly emit light at a longer wave length
than the light absorbed. This emitted (fluorescent)
light goes out in all directions. Most common
fluorescent tracers are compounds which absorb
green light and emit red fluorescent
light.
What
does PPM mean?
A: PPM means parts per
million. 1 PPM means the color of the product is
visible in clear water at one part dye tracing
product to a million parts water. 1 PPM in 10,000
gallons of water requires approximately 1 pint of
dye tracing liquid concentrate. This is generally
referred to as a strong visual concentration
level.
Which
is best, tablets, powder, liquid or
wax?
A: For small amounts of
water, Bright Dyes tablets are clean and easy to
use - no measuring is required. Bright Dyes may be
dropped or flushed directly into a drain, sewer,
septic system, etc. where they will dissolve in
about 3-5 minutes. Or, they may be dissolved in a
small amount of water first.
For larger bodies of
water, Bright Dyes powder or Bright Dyes liquid
concentrate may be most suitable for your
needs.
In the situation of
long-term flow study a Bright Dyes wax product such
as cakes, cones or donuts should be
used.
Is
it less expensive to use powder or liquid
concentrate?
A: Bright Dyes Standard
Blue and FLT Yellow/Green are a little less
expensive per gallons treated in the powder and
liquid concentrate, then FWT Red.
* 1 pound of Bright Dyes
Std. Blue or FLT Yellow/ Green powder will create a
strong visual in 120,000 gallons of water.
* 1 pound of Bright Dyes
FWT Red powder will create a strong visual in
60,400 gallons of water.
* 1 pint of Bright Dyes
Std. Blue or FLT Yellow/Green liquid concentrate
will create a strong visual in 12,500 gallons of
water.
* 1 pint of Bright Dyes
FWT Red 25 will create a strong visual in 6,250
gallons of water.
What
color of Bright Dyes should I use?
A: What color of Bright
Dyes you use will depend on the color of water, or
type of water: Any color can be used in clear
water. If the water were yellow, Bright Dyes
Fluorescent FWT Red would be best, especially if
visual methods are used to estimate the dye
concentration. If the water were a murky brown in
color, Bright Dyes Fluorescent FLT Yellow/Green
would be appropriate. Although the Bright Dyes
Standard Blue dye may be used in tracing
situations, it is not fluorescent and is limited to
visual methods and for cosmetic
purposes.
Which
Bright Dye should I use?
A: It depends on the usage
and the volume of water.
FOR UNMETERED
USE:
0-20,000 gallons of water
use Bright Dyes tablets, or Bright Dyes liquid
concentrate.
20,000-50,000 gallons of
water use Bright Dyes tablets, liquid concentrate,
or wax.
50,000 + gallons of water
use Bright Dyes wax donuts, powder or liquid
concentrate.
Where metering input is
required, use Bright Dyes liquid concentrate for
any volume of water. Where a water-based solution
needs to be labeled for detection with a black
light or fluoremetric equipment, use Bright Dyes
Fluoretrack II liquid concentrate.
Are
Bright Dyes safe for the
environment?
A: Bright Dyes are EPA
acceptable and they are the only full line of
tracer products certified by the National
Sanitation Foundation (NSF) to the ANSI/NSF
Standard 60 for use in potable water at recommended
levels. They are biodegradable and safe for the
environment.
Fluorescent dyes are
relatively unreactive chemically, and in most cases
do not interact with the "system".
Which
Bright Dyes water tracing product should I
order?
A. It depends on the usage
and the amount of water involved, what you plan to
use the product for, and how much water is
involved.
SMALL VOLUMES OF WATER-
(0-20,000 gallons) Use Bright Dyes tablets
A. Septic system
analysis
B. Leak
detection
C. Plumbing and
sewer tracing
D. Storm and sewer
drains
MODERATRE VOLUMES OF
WATER-(20,000-50,000 gallons) Use Bright Dyes
tablets, liquid concentrate or wax
cones.
A. Examine water movement,
current, flows
B. Flow mapping
and tracing
C. Flow time
studies
D. Storm and sewer
drains
LARGE VOLUMES OF
WATER-50,000 + gallons- Use Bright Dyes liquid
concentrate, powder or wax donuts.
A. Leak
detection
B. Flow
studies
C. Pollution
studies
D. Condenser tubes
and coils
E. Power plant
piping
F. Lakes, rivers,
ponds
FOR PROJECTS WHERE
METERING OF INPUT INTO SYSTEMS IS REQUIRED- Use
Bright Dyes liquid concentrate.
A. Flow
studies
B.
Dilution
C. Leak
detection
D. Pollution
detection, septic tanks, sewer lines
How
much water will Bright Dyes color?
A. There are a lot of
different factors, which may effect how much Bright
Dyes product you will need. Below are some rough
guidelines.
Tablets- As a general
rule, 1 tablet will provide a strong visual in 60
gallons of water.
Example: in a 1,200 gallon
septic system would require between 15-20 tablets
for a strong visual inspection.
Liquid concentrate-As a
general rule, 1-pint will provide a strong visual
in 10,000 gallons of water.
For example, a collection
line having 10,000 gallons of flow, would require 1
pint of liquid concentrate for a strong visual
inspection.
Powder- as a general rule,
1-pound of Bright Dyes powder will provide a strong
visual in 120,000 gallons of water.
For example, a cooling
tower holding 240,000 gallons of water would
require 2 pounds of Bright Dyes powder for a strong
visual.
What
should be done if someone ingests a tablet, and are
they toxic or hazardous?
A: Bright Dyes are safe
and non-toxic and will not adversely affect ones
health. In case of injection, drink several large
glasses of water. The person's perspiration and
urine will be tinted the color of the dye for a
short period of time.
How
can I remove the dye?
A. The color of all dyes
will disappear if the solution is mixed with
chlorine. Add approximately 4 grams of 12% bleach
for every gram of product in the solution. Adding
water will also dilute dye concentration and reduce
coloration, or even eliminate color all together
depending on volume of water added.
