Dear Investors,
I am pleased to report that HSA's water testing unit, led by MOU Lina who joined the company in August, has completed the first in-house laboratory test of Hydrosmart. The team's work had been delayed by difficulties in obtaining the necessary chemical agents during the build-up to and holding of the Olympic Games. With the easing of the supply situation, Lina organized and managed a set of very professional tests of the ability of Hydrosmart to bring the pH level of water toward the optimum level. The results are shown below.
Basic Concepts
pH is a measure of the acidity or alkalinity of a particular solution.
The pH scale is expressed as the negative logarithm of the hydrogen ion concentration ranging from 0 [high concentration of hydronium ions (H+) = acidic] to 14 [high concentration of hydroxide ions (OH-) = alkaline/basic].
The pH value of pure water is 7 (neither acidic nor alkaline). This is generally considered to be the ideal condition for fresh water. However, various factors can cause the water parameters to swing several notches towards acidic or alkaline.
Below is the brief test report of Hydrosmart's effect on the pH value of water:

- Test aim
To evaluate Hydrosmart's effect on acidic wastewater and alkaline wastewater by testing the pH value of untreated and treated water. Three tests were conducted and the results averaged.
- Test condition
The test was conducted in the HSA lab, using a pump to form a water cycle through Hydrosmart and measuring the pH level before and after being treated by Hydrosmart. Each test lasted twenty hours (the results for the first ninety minutes are shown in the chart below).
- Test equipment
Portable pH meter (pH-107A) and reactive agents.
- Test results:
- Explanation of results
After being treated by Hydrosmart, the pH level of both alkaline wastewater and acidic wastewater moved very close to the neutral level and stabilised at that level.
- Conclusion
Hydrosmart can change alkaline and acidic wastewater to neutral water. In the tests, it reduced the pH value of alkaline wastewater from 10.7 to 7.5 and increased the pH value of acidic wastewater from 4.5 to 6.5. When the pH level is near to the neutral value, it stabilises.
