Turbu-Flow — Reducers Water Surface Tension

What is water Surface Tension?

The surface tension of water is 72 dynes/cm at 25 degrees Celsius. It would take a force of 72 dynes to break a surface film of water 1cm long. The surface tension of water decreases significantly with temperature . The surface tension arises from the polar nature of the water.

Hot water is a better cleaning agent because the lower surface tension makes it a better “wetting agent” to get into the pores and fissures rather than bridging them with surface tension. Soaps and detergents further lower the surface tension.

What Turbu-Flow does to Water Surface Tension

The following test in Table 1 were prepared by
Enviro Test Laboratories
Waterloo
Ontario , Canada

The samples of Raw and Treated water were generated on April 27, 2004 and were shipped to Core Labs in Calgary for analysis.

The results of the analysis are summarised below.

TABLE 1.

	Untreated Water		Treated Water
Date	Room Temp	80 Degrees C	Room Temp	80 Degrees C
May 5, 2004	79,0 dynes/cm	na	69.5 dynes/cm	na
May 25, 2004	79.1 dynes/cm	69.2 dynes/cm	77.4 dynes/cm	67.5 dynes/cm

Table 1 shows a dramatic decrease in water surface tension after a single pass through the Turbu-Flow unit. The sample had been generated on April 27 and was analysed 8 days later. Based on an 8 day old sample, the surface tension dropped from 79 dynes/cm in the untreated water to 69.5 dynes/cm in the Turbu-Flow treated water.

To further delineate the impact of time and temperature on the surface tension, the analysis was repeated almost 3 weeks later on the May 25. At this time the Turbu-Flow sample exhibited only a slight decrease in surface tension over the untreated water at both room temperature and at 80 degrees C. This analysis suggests that Turbu-Flow treated water will revert back to its original surface tension over time, but of more significance is the fact that for a period of more than a week after the sample is passed through the Turbu-Flow, it exhibits a surface tension that is similar in magnitude to water that has been heated to 80 degrees C.

In Summary

8 Days AFTER the water sample was taken.
Turbu-Flow reduced the surface tension of water by 9.5 dynes/cm.

30 Days AFTER the water sample was taken.
Turbu-Flow treated water was 1.7 dynes/cm less than untreated water at room temperature.

After passing through a Turbu-Flow the surface temperature of room temperature water in similar in magnitude to water that has been heated to 80 degrees C.

What does this do for you?

Washing your clothes in COLD water will be as effective as washing your clothes in hot water.
Washing detergents will work more effectively giving you cleaner clothes and saving you money.
Less spotting on your car after cleaning it. The lower the surface tension the smaller the droplets.
Softer water to bath in.
Your skin and hair will feel softer.
Swimming pool water will be softer to swim in.
Cleaning the pool will be easier.
When watering your garden a lower water surface tension allows water to be absorbed into the soil and plants more quickly.

Turbu-Flow conforms to AS/NZS 4020: 1999 as being suitable for Potable Water.
