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. 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 MODERATRE VOLUMES OF WATER-(20,000-50,000 gallons) Use Bright Dyes tablets, liquid concentrate or wax cones. A.
Examine water movement,
current, flows LARGE VOLUMES OF WATER-50,000 + gallons- Use Bright Dyes liquid concentrate, powder or wax donuts. A.
Leak detection FOR PROJECTS WHERE METERING OF INPUT INTO SYSTEMS IS REQUIRED- Use Bright Dyes liquid concentrate. A.
Flow studies 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. Liquid
concentrate-As a general
rule, 1-pint will provide
a strong visual in 10,000
gallons of water. Powder-
as a general rule, 1-pound
of Bright Dyes powder
will provide a strong
visual in 120,000 gallons
of water. 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. 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. |
