Aluminium chloride, also known as aluminium trichloride, is an inorganic compound with the formula AlCl 3. It forms a hexahydrate with the formula [Al(H 2 O) 6 ]Cl 3 , containing six water molecules of hydration .
In water purification, this compound is preferred in some cases because of its high charge, which makes it more effective at destabilizing and removing suspended materials than other aluminium salts such as aluminium sulfate, aluminium chloride and various forms of polyaluminium chloride (PAC) and polyaluminium chlorosulfate, in which the ...
Water-reactive substances [1] are those that spontaneously undergo a chemical reaction with water, often noted as generating flammable gas. [2] Some are highly reducing in nature. [ 3 ] Notable examples include alkali metals , lithium through caesium , and alkaline earth metals , magnesium through barium .
The alum dosage is also insufficient to cause toxicity in humans, and is often similar to alum doses used in conventional drinking water treatment. [8] To reduce negative biological effects, the accepted limit for dissolved aluminum concentrations in a water body is 50 μg Al/L and pH should be restricted to a range of 5.5-9. [2]

The proponents of raw water praise the fact that it doesn't contain chemicals like chlorine, fluoride or chloramines -- but that might not be a good thing. Why that ‘raw water' trend is actually ...
