The silicate concentration does not decrease after JBL SilikatEx (rapid) is used. The silicate test always shows a deep-blue to black colouration, which indicates more than 6 mg/l of silicate.
A reading of > 6 mg/l with the silicate test means that there are more than 6 mg/l of silicate in the water. It is not possible to check how many more silicates are present. There may be 10, 50 or even more mg/l of silicates. There are more than 40 mg/l in tap waters in many regions today. The respective water supplier can provide more detailed information or you can dilute the water to be measured with silicate-free water e.g. water that has been distilled twice prior to measuring. In the event that osmosis water is supposed to be used, its silicate content should also be measured. With 40 mg/l of silicates in the starting water JBL Osmose 120 is able to achieve a permeate with 0.4 – 1.2 mg/l of silicate.
Therefore, with silicate values this high, the lowering effect of JBL SilikatEx can only be checked by diluting the water before measuring it.
500 g JBL SilikatEx binds 5000 mg silicate out of the water.
400 g JBL SilikatEx Rapid binds approx. 12000 mg silicate out of the water.
Sample calculation:
100 l tank with 50 mg/l of silicate in the starting water:
100 l x 50 mg/l = 5,000 mg of silicate.
