Pure water is plain H2O, No other elements like salts and solids are present in the water. We know the water has particles in by using a TDS meter (total dissolved solids). This measures the unit for water purity.
The more minerals and solid particles in the water, the higher the TDS number. 000ppm (parts per million) is the purest form of water. the World Health Organization discovered that water from natural sources can have a TDS number that varies from less than 30 ppm (or milligrams per litre, which is the same) up to 6000 ppm. The TDS meter is the tool that measures how many particles are in the water.
The answer is ultra-pure water does not conduct electricity . the minerals and particles in the water that conduct electricity, without them the water molecules can’t pass electrical current.
So how do you make it pure?
First in the water purification process we use reverse osmosis (RO). Water is pushed against a special semipermeable membrane that separates minerals and solid particles from water molecules. That allows us to get around 90% + pure water but we still need to get it fully purified.
Second in the process is Deionisation (DI). Although pretty much most of the solids are removed in the pre-filtering, the water still contains some positive and negative ions like Calcium (Ca++), Magnesium (Mg++), Iron (Fe+++), Chlorides (Cl-), Sulfates (SO4–), Carbonates (CO3–) and probably Nitrates (NO3-) as well. These positive cations and negative anions are attracted by the ion exchange resins and what’s left is pure H2O molecules.
Ones we have 000ppm we are then able to scrub and rinse your windows cleaning, using the various types of purification system. We then use our telescopic water fed poles that brushes your window surface.
