• Mercury Reduction Test

    A challenge water was prepared with Mercury at a concentration of 6 µg/L. 4th Phase Mineral Solution was added to the solution at a concentration of 2 mL of 4th Phase Mineral Solution per liter of challenge water. The solution was filtered through the 4th Phase Ceramic Filter System, and then tested for Mercury after 24, and 48 hours of adding the 4th Phase solution. The concentration of Mercury decreased to non-detectable levels.

  • Chloramine Reduction Test

    A water solution prepared with Chloramine at a concentration of 2.75 mg/L of Chloramine was tested, 4th Phase Water was added to the solution at a concentration of 2 mL of 4th Phase Water per liter of Chloramine solution and the solution was tested after 1, 6, 12, 24, 36, and 48 hours of adding the 4th Phase Water solution. The concentration of Chloramine decreased each time until it was not detected by the Standard Test Method 4500-Cl-G.

  • VOC Reduction Test

    A water solution prepared with a VOC standard concentration of 20 µg/L of each organic volatile compound (VOC) was tested. 4th Phase Liquid Crystal Concentrate was added to separate beakers at a concentration of 1 mL and 2 mL of 4th Phase Liquid Crystal Concentrate per liter of VOC solution. The solutions were set in open beakers for 48 hours and tested after being filtered through the 4th Phase Liquid Crystal Concentrate Water Filter System. The concentration of VOC’s were below the method detection limit for each compound on each solution.

  • Free Chlorine Reduction Test

    4th Phase Liquid Crystal Concentrate solution was tested by applying the protocol NSF Standard 42 for chlorine reduction. The solution prepared with 1 mL of the 4th Phase Liquid Crystal Concentrate solution dissolved in a 1000 mL volumetric flask with the challenge water (2.08 ppm of Free Chlorine) reduced the Free Chlorine in the challenge water by 100.0%.

  • UV Absorption Test

    4th Phase Liquid Crystal Concentrate was tested for Ultraviolet/Visible absorption compare to the absorption of tap and Ultrapure water. The 4th Phase Liquid Crystal Concentrate shows a high absorption in the range of 190 to 380 nm (Ultraviolet), and very low absorption in the range of 380 to 750 nm (visible range).

  • Antibacterial Properties Test

    4th Phase Liquid Crystal Concentrate solution by 4th Phase Water was tested for antibacterial properties. Four control batches were prepared with four different types of Coliform bacteria in sterilized water and tested for Total Coliform/E. coli using the m-ColiBlue-24 method. Four similar Coliform batches were prepared and treated with the 4th Phase Liquid Crystal Concentrate solution in a 1:1000 proportion and tested again using the same Coliform method. Coliform bacteria were present in the control batches but absent in the treated batches.

  • Fluoride Reduction Test

    Two water solutions prepared with a Sodium Fluoride concentration of 4 mg/L of Fluoride anion were tested. 4th Phase Liquid Crystal Concentrate was added to each solution at a concentration of 1 tsp. and 2 tsp. of 4th Phase Liquid Crystal Concentrate per gallon of Sodium Fluoride solution and the solutions were tested immediately after adding the 4th Phase Liquid Crystal Concentrate, then tested again after 30 minutes, 1 hour, 2 hours, 24 hours, and after filtering through the Fourth Phase Filter system. The concentration of Fluoride anion decreased each time until it was not detected by the EPA method 340.2.
