Hi Total Dissolved Silica 114g/m3 as SiO2 (silicon x 2.14 by calculation) I have come across the same problem to remove Silica (approximately 30 mg/L) in bore water to drinking water standard. The silica will condense at the first big pressure drop, which is invariably, across your turbine, leaving silica deposits and consequent loss of balance, vibration, and eventual catastrophe! There is no such thing as silica intoxication, as long as .your body keeps up normal levels of B1 vitamin and potassium, and the water … Kind Regards, Q. Dear Brijesh, I like your question, but let me ask something: if we have DI water but silica is 20 ppm, we want it 0.1 ppm, will RO work for it? An easy way to test if scaling might be silica is to wipe the affected area with white vinegar. The water temperature is around 20 to 25 degree. The product works by using a microbe that accepts silica through the cell wall, giving enough surface area and charge to physically remove the silica. (required), chemical treatment Our lab in-charge says 10 ppm silica in DM water ... is that a right or wrong report, please tell me. A. Silica can be removed from raw water easily with standard demineralization techniques. Q. Dear, in our boiler the silica contains 0.53. } You should call up one of the many companies that specializes in this sort of thing, explain your predicament, and get some quotes to help you decide how much it is worth to you annually not to have mineral deposits on glassware and fixtures. This is not lime scale because products for removal of lime scale have no effect. Thank you again, A discussion started in By the way, I chose Chlorine gas out of potassium permanganate, ozone, and chlorine dioxide. Please reply at the earliest. RO projection software shows silica rejection at level of 99.3 %, but reality is different-close to 90 %. However, if this is DI water, then further treatment is needed for most uses. Silica can exist in water as relatively large particles, known as silica granules or granular silicates. Yes. When questions are presented as requests for clarification of suggestions that have been offered, they usually elicit enthusiastic response; but if earlier answers are just blown off, and questions are posed as "start over for me because I can't be bothered putting in any work to try to appreciate what you wrote", the thread often dies).
