PRO • pHx Acid Life Extender
Prove To Yourself That PRO • pHx Works
With Your Own Production In-Tank Chemistry.
Take your most contaminated acid bath (Nitric, Sulfuric, Hydrochloric, etc.), such as one ready for waste treatment and make three equal Samples. Add 1% PRO • pHx to two of the three samples of spent acid. Keep one Sample as a control.
Wait two days then titrate and bring back the acid to its original concentration.
Filter one (only) of the PRO • pHx treated samples
with a 5 to 50 micron suction or pressure feed unit. The micron size that
does best is dependant on the type of metal and amount of organics present.
If you use a paper filter and gravity, then filter continuously 3 to 5
times to simulate continous filtration. Leave the second treated Sample
unfiltered for observation.
If your organics and/or metals in the acid are high, you will see a marked difference after filtration. Even the appearance (clarity) of the acid will be greatly improved after the treatment. If you continue to add metals and/or organics to the treated acid, they will continue to become filterable over a one to two day period. New acids created in lab conditions have not provided satisfactory results. Spent acids or heavily contaminated acids have produced visible and measurable results.
PRO • pHx adds of over 1% are NOT effective or necessary.
Do NOT over treat.
Continue to use (contaminate) the treated and restored acid as your production
tank acid. Ongoing maintenance requires
1) filtration
2) acid spikes (add back acid)
3) keeping PRO • pHx in the range of 1% (down to 1/2%)
ratio to the total acid / water volume.
If You Do This, You Will Never Dispose of a Contaminated Acid Again and Will Immediately Begin to Recapture Operating Cost as Profit!
The PRO • pHx FAQ Sheet answers most questions when
beginning the first PRO • pHx applications.
Here Is Another Way To Test & Demonstrate The Effectiveness Of PRO • pHx
Contaminate your acid until its stripping effectiveness has stopped (even with titration and adding back acid to original concentration).
Add 1% PRO • pHx and filter as stated above and filter.
The acid will once again clean-up and strip effectively.
