Sodium hypochlorite can also be used for point-of-use disinfection of drinking water, [37] taking 0.2–2 mg of sodium hypochlorite per liter of water. [ 38 ] Dilute solutions (50 ppm to 1.5%) are found in disinfecting sprays and wipes used on hard surfaces.
4 clo − 2 + 2 h 2 so 4 → 2 clo 2 + hclo 3 + 2 so 2− 4 + h 2 o + hcl All three methods can produce chlorine dioxide with high chlorite conversion yield. Unlike the other processes, the chlorite–sulfuric acid method is completely chlorine-free, although it suffers from the requirement of 25% more chlorite to produce an equivalent amount ...
The chlorination of the water supply helped stop the epidemic and as a precaution, the chlorination was continued until 1911 when a new water supply was commissioned.

Double-distilled water (abbreviated "ddH 2 O", "Bidest. water" or "DDW") is prepared by slow boiling the uncontaminated condensed water vapor from a prior slow boiling. Historically, it was the de facto standard for highly purified laboratory water for biochemistry and used in laboratory trace analysis until combination purification methods of ...
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, and ...
The bag was made of canvas and could hold 36 gallons of water. It was porous and held up by ropes, purifying water with the help of calcium hypochlorite solution. Each bag had a faucet attached, which was used to flush water for testing, as well as dispensing for use. This became the basis for present day systems of municipal water purification ...
