Reverse Osmosis / Distilled / Tap (PH/TDS)
This test was on using different water sources and comparing their PH and Total Dissolved Solids (TDS) in parts per million (ppm).
I used the following for data collection:
- Niagara Distilled Water
- Industrial Reverse Osmosis Water
- Tap water
- Hanna pHep pH Meter
- Panpeha pH Strips
- HM TDS Meter
I bought a 500 ml FIJI bottled water to use as a control for the measuring instruments because the label states the pH is 7.8 and the TDS is 220.
FIJI Water: Hanna pH
FIJI Water: Panpeha pH
FIJI Water: TDS
So much for the control.
FIJI PH = 7.1
FIJI TDS = 139 ppm
Reverse Osmosis Water: Hanna pH
Reverse Osmosis Water: Panpeha pH
Reverse Osmosis Water: TDS
Distilled Water: Hanna pH
Distilled Water: Panpeha pH
Distilled Water: TDS
Tap Water: Hanna pH
Tap Water: Panpeha pH
Tap Water: TDS
Results
Comparison
Reverse Osmosis:
pH 6.2
TDS 003 ppm = 0.0003%
Distilled Water:
pH 6.1
TDS 000 ppm = 0.0000%
Tap Water:
pH 7.3
TDS 365 ppm = 0.0365%
The pH and TDS shows Distilled and RO to be very very close. This prompted me to do another comparison using water testing kits.
Reverse Osmosis / Distilled (Chlorine)
I used the following for data collection:
- Niagara Distilled Water
- Industrial Reverse Osmosis Water
- 2x Culligan TK-2 Water Test Kits
Reverse Osmosis Water: Chlorine
Reverse Osmosis Water: Iron
Reverse Osmosis Water: Hardness / Nitrite / Nitrate
Distilled Water: Chlorine
Distilled Water: Iron
Distilled Water: Hardness / Nitrite / Nitrate
Results
Comparison
Reverse Osmosis:
Chlorine 0.1 ppm = 0.00001%
Iron 0.0 ppm
Hardness 0
Nitrite 0
Nitrate 0
Distilled:
Chlorine 0.1 ppm = 0.00001%
Iron 0.0 ppm
Hardness 0
Nitrite 0
Nitrate 0
1.0 ppm = 1.0 mg per Liter = 1.0 mg/L
0.1 ppm = 0.1 mg per Liter = 0.1 mg/L
I believe the test kit was not that precise in accuracy and that is why distilled water did not show 0.0 chlorine as it should have. At any rate, both water types showed the same reading according to my color comparison skills. Although, some portions of the strip looked to be 0.0 color and some looked 0.1 color. I recorded 0.1 because it was not clearly observable.
In conclusion, the difference between Reverse Osmosis and Distilled water is extremely minute (at least from my water sources). Obviously this comparison is not meant to say that all Distilled and Reverse Osmosis waters reflect this exact data.
A check of my local tap water quality shows a 0.99 ppm of Chlorine.
I feel using Reverse Osmosis water is equally acceptable to that of Distilled water with hydrogen peroxide therapy (at least from my water sources). Results may vary from source to source.
Note: chlorinated water will only "degrade" the hydrogen peroxide according to Dr. David G. Williams website post: http://www.drdavidwilliams.com/how-to-prevent-infections/
