3. Water purification - Wikipedia

   en.wikipedia.org/wiki/Water_purification

   Fresh water can have widely ranging pH values depending on the geology of the drainage basin or aquifer and the influence of contaminant inputs . If the water is acidic (lower than 7), lime, soda ash, or sodium hydroxide can be added to raise the pH during water purification processes. Lime addition increases the calcium ion concentration, thus ...

4. Ultrapure water - Wikipedia

   en.wikipedia.org/wiki/Ultrapure_water

   Ultrapure water (UPW), high-purity water or highly purified water (HPW) is water that has been purified to uncommonly stringent specifications. Ultrapure water is a term commonly used in manufacturing to emphasize the fact that the water is treated to the highest levels of purity for all contaminant types, including: organic and inorganic compounds; dissolved and particulate matter; volatile ...

5. Purified water - Wikipedia

   en.wikipedia.org/wiki/Purified_water

   Deionized water is used in water-fog fire-extinguishing systems used in sensitive environments, such as where high-voltage electrical and sensitive electronic equipment is used. The 'sprinkler' nozzles use much finer spray jets than other systems and operate at up 35 MPa (350 bar; 5,000 psi) of pressure.

6. Schlenk-frit - Wikipedia

   en.wikipedia.org/wiki/Schlenk-frit

   A Schlenk-frit is a laboratory filtration device operating under inert gas conditions (schlenk conditions). It separates air- and water-sensitive suspensions into liquid and solid parts. A Schlenk-frit is made of a glass tube with a ground glass joint at both ends, a fused filter (a porous glass disk) and valves at both sides.
