Water Tracing Dye Technical Data

dyefamily.JPG (18407 bytes)

Fluorescent dyes are unique, high quality formulations preferred by most professionals for visual leak detection.

With these dyes, you can test sewer lines for infiltration, locate sewer lines, check lines for illegal connections, proving septic bypasses and toilet leaks, check circulation through sludge beds and detect leaks in a closed system.

These dyes come in a choice of three colors.

 
  • Dye tracing products are used in many analytical applications.
  • The unique needs of our customers seem almost unlimited.
  • Some of the most common uses are:
    • Plumbing tracing
    • Flow mapping and rate of flow studies
    • Power plant piping tracing
    • Pollution studies
    • Lake, river and pond analysis
    • Storm and sewer drain analysis
    • Retention time studies
    • Condenser ceil and tube studies
    • Septic system analysis
    • Leak detection in many fluid
      carrying systems

How Fluorescent Dye Tracing Products Work:

The "visual" aspect of dyes refers to normal reflection of light as color. The "fluorescent" aspect refers to special properties of some chemicals to absorb certain wavelengths and then emit, rather than reflect, light in response.

The emission can be seen by using a "black" ultraviolet light or precisely measured with a fluorometer. The reflected and emitted light have different wavelengths and are, therefore, not the same color. 

Fluorescent properties are of greatest value when:

  • Tracing must be done when there is no sun or sufficient artificial light (in a sewer or a cave, for instance)

  • Precise quantified data is required

  • Very small amounts of tracing material is allowed

The maximum absorbance/emission wavelengths of our products are :
Product Absorption Emission
Fluorescent Red 550 nm 588 nm
Fluorescent Yellow / Green 490 nm 520 nm
Clear 349 nm 430 nm
Blue 630 nm na

Normally, the blue products are for visual tracing only.

What PPB means?

Most of our products contain fluorescent dyes, which can be detected visually, or with the use of ultraviolet light or fluorometer.

"PPB" refers to one part of active dye per billion parts of water. Using a fluorometer, the active dye can often be detected at levels less than one ppb. All data is presented as reference points only and should not be regarded as a recommendation.

Users should make their own determination of appropriate dilution levels in any specific situation, which will vary with the nature, condition, and use of the water or liquid and the specific evaluation to be performed.

How to calculate the size of a body of water :

One gallon of water occupies .1337 cubic feet. For a rectangular tank, multiply depth in feet times width times length divided by the factor .1337 to establish the number of gallons. For more complicated bodies of water, formulas can be found in scientific texts on water utility management, hydrology etc.

 
Other Information
For stream tracing and pollution detection

Introduce tracers into the water at the source or suspected source of pollution. Allow sufficient time as calculated, to permit the dye tracer to reach the effluent or recipient location. Take samples of water for analysis.

 
Dye tablets

May be dropped or flushed directly into drains, sewers or other points in the system. However, it may be desirable to dissolve them in a small amount of water to form a calculated concentration prior to use.

Special larger shapes (cakes, cones, and donuts) have been designed to provide optimum dissolution rates in larger systems. Donuts are frequently suspended from a line or string into the body of water. Cakes and donuts are sealed in a handy water-soluble film for ease of use.

 
Light stability

Blue has the highest degree of light stability and red is recommended for yellow and green backgrounds such as algae rich water. Fluorescent Red, Blue and Fluorescent Yellow/Green should be used in water bearing heavy sediment loads or when passing through soil with high day content.

Photo degradation takes place in sunlight at different rates for different dyes. Red takes from approximately five to seven days and yellow/green fades in two to three days. Blue, on the other hand, breaks down in three to four weeks.

The color of all dyes will disappear if the solution is mixed with chlorine. Add approximately 4 grams of 12% bleach to every gram of product in solution.

 
Examples of Specific Projects
  • Test sewer lines for infiltration
  • Locate sewer lines
  • Check for illegal connections
  • Prove septic bypasses
  • Identify indirect cross-connections
  • Check drain pipes, downspouts, and gutters to assure drainage into proper channels
  • Use in inspection service for certification and re-inspection documentation
  • Analyze travel times
  • Toilet leak detection kits are frequently used by plumbers and salespeople. Municipalities and utilities use them as part of public relations and water conservation programs.
  • Detect leaks in closed systems and cooling systems of manufacturing plants
  • Study infiltration and industrial water piping systems
  • Trace acid coming through cooling systems
  • Check pump systems' flow, and preventative maintenance programs
  • Detect sewer leaks into ponds, lagoons and reservoir lines
  • Check circulation through sludge beds and measure discharge flow from water tanks
  • Illustrate the hydraulic characteristics of streams and other water bodies
  • Identify and differentiate batches of slurry
  • Measure the speed and longevity of material passing through a system
