What is pure water?
Unlike ordinary tap water that has been treated, pure water contains none of the minerals found in our drinking water such as potassium, calcium and magnesium, these are removed through a process known as reverse osmosis.
Reverse osmosis incorporates a five stage filter system where tap water is forced through under pressure. Once passed through the system it then goes into a final De -Ionisation vessel that finishes the purification process.
In the south east the water is considered to be ‘hard’. This degree of hardness can be measured on a TDS (total dissolved solids) meter. A sample taken from Ashford Kent shows a reading of 380ppm (parts per million). This water would not have the cleaning qualities of pure water and all the impurities measured in the water would result in spotting on the glass. Pure water has a TDS reading of 000ppm therefore leaving no trace on the glass once dry!
Unlike ordinary tap water, The water fed pole system utilises a 5 Stage Water Treatment System to produce 100% pure deionized laboratory graded water on the window with zero parts per million.
Stage1: Sediment filter, we use 10 micron Sediment Poly Pro Filters, for the removal of sediments, dirt, sand and rust.
Stage 2: Carbon filter, Used for chlorine removal, other heavy metal and contaminants removed.
Stage 3: GAC filter (Granular Activated Carbon) water flows through a bed of activated carbon granules which trap some particulate matter and remove chlorine, organic contaminants, chemicals, and undesirable tastes and odours
Stage 4: RO (Reverse Osmosis) The Reverse Osmosis membrane has a tight pore structure (less than 0.0001 micron or 500,000 times less than the diameter of a human hair) that effectively removes up to 99% of all contaminants and impurities such as total dissolved solids, chemicals, bacteria and viruses from the water. Anti-microbial filters used in Reverse Osmosis also help to remove unwanted odours, colors and tastes from water.
Stage 5: DI (Deionization) is the removal of mineral ions by using the ion exchange process. Using a mixed bed of anion and cation resins; ions, salts and minerals can be entirely removed from water.
When a DI filter is used after the RO membrane, you can expect 100% removal of the TDS (minerals) in the water resulting in 000ppm (Parts Per Million).
Which then produces pure water and a streak clean finish on your windows
