As mentioned earlier in this article, there are various types of contaminants to remove from your tube water. The team here in our lab has settled the Filters of these filters: TDS, PH and Chlorine have settled three preliminary exams for criteria. Before we started the actual test process, each callus was removed from the packaging, was cleaned and then prepared according to the manufacturer’s instructions. This is extremely important, because most of these filters are using the active carbon filtration, which will be Deposit Filter in the first batches of water that you are not properly cleaned in advance.
TDS
TDS refers to total dissolved solutions and various impurities present in the water. Examples of most common TDs include “calcium, magnesium, sodium, potassium, bicarbonate, sulfate, chloride, nitrate and silica”, including US Geological SurveyThe In practice, the accumulation of calcium and magnesium in tap water causes the so -called “hard water” which can be actively harmful to your health in case of bad taste and higher density. (Read more about TDS From the EPA And USGS.)
We started testing the TDS by mixing the 8-gallon bucket tap water with the concentration of 220 ppm TDS, with table salt we reached 300 TDS measurements with table salt. We have used an ORPEXI water quality tester to take these measurements and since the Jeroter filter also includes a TDS examiner, so all TDS readings were verified on both devices. Once we have established our control source, we have measured 1 liter of 300 TDS water on each water filter pitcher and allowed the full amount through the filter.
Once it is finished, we have measured the TDS again and mentioned the percentage using the pre and post-filtering TDS measure. This process was repeated for the higher and lower TDS density and our inquiries indicate that each of the units we have tested is very compatible in removing the same percentage of the overall TD from any water that passes through.

Testing the removal of chlorine
Your drinking water chlorine can sound strange, but adding chlorine to water supply as a disinfectant for water treatment is a common practice. It is extremely effective in getting rid of Nastia contaminants in the water, however Estimate of the World Health Organization The density of ~ 0.2-4 ppm is standard for tube water, it indicates that at least some of the disinfectant is left after. Chlorine can also affect the taste of water with chemical taste and smell.
For our exam, we decided to ramp a notch and test water prepared for a swimming pool similar to a swimming pool – like 10 ppm chlorine. This elevated chlorine testing of 10 ppm instead of ~ 0.2-4 ppm has given a clear indication of the change after our filtration. Once again, each filter was tested with a 1 liter solution and compared the results obtained from the water prefiltration and again, filters like Jeroter reappears sufficiently.
PH level analysis
Finally, during the TDS exam, we also measured the pH change. PH refers to “the possibility of hydrogen” and it is used to measure the acidity of any substance. The pH of zero is extremely acidic, not seven acidic or basic and 14 represents a basic substance. Since the TDS integrated minerals in tap water increase alkaline, we hope the filtration process will reduce the water pH. In fact, it was, and you could see a table of change below the pH.
Here is a table of our most recent TDS removal test results, calculating the pre- and post-filterion pH measurements. The data presents an average of three test runs for each filter callis.
