Aluminium sulfate is a salt with the formula Al 2 (SO 4) 3.It is soluble in water and is mainly used as a coagulating agent (promoting particle collision by neutralizing charge) in the purification of drinking water [3] [4] and wastewater treatment plants, and also in paper manufacturing.
The Camelford water pollution incident involved the accidental contamination of the drinking water supply to the town of Camelford, Cornwall, in July 1988.Twenty tonnes of aluminium sulphate was inadvertently added to the water supply, raising the concentration to 3,000 times the admissible level.
One method of eutrophication remediation is the application of aluminum sulfate, a salt commonly used in the coagulation process of drinking water treatment. Aluminum sulfate, or "alum" as it is commonly referred, has been found to be an effective lake management tool by reducing the phosphorus load. [2] Sediment core sampled from a Minnesota lake.
This is especially concerning as treated wastewater is expected to make up an increasing proportion of drinking water supplies as climate change-fueled drought shrinks water sources, Ruyle told CNN.

1. It's Typically Worse Than Tap Water. Bottled water, believe it or not, isn't held to the same standards as tap water. That means harmful chemicals can leach from the bottle, especially if it ...
Excessive use of aluminum salts produces sludge and adverse health effects through aluminum solubility. The so-called Nalgonda technique for reduction of fluoride involves stirring in of alum and lime , whereupon some of the fluoride precipitates together with aluminum hydroxide, and the water can be decanted and filtered.
Particles finer than 0.1 μm (10 −7 m) in water remain continuously in motion due to electrostatic charge (often negative) which causes them to repel each other. [citation needed] Once their electrostatic charge is neutralized by the use of a coagulant chemical, the finer particles start to collide and agglomerate (collect together) under the influence of Van der Waals forces.
