Water from a river pond or lake contains very fine clay particles. To make them settle at a faster rate a chemical substance called alum in powdered form is added to such mixtures. It dissolves in water and forms clusters with clay and dust particles making them heavier and increasing the rate of sedimentation.

Give reason that alum is used in purification of river water - 7037279

In later years an extensive use of alum has been made in the many processes of purifying water. It is not improbable that aside from its effect in precipitating matter mechanically by envelopment with the precipitating basic aluminic sulphate, the alum exerts a distinct coagulative action on the albuminous substances in the water, rendering them insoluble, and thus causing their precipitation; perhaps the same or similar effect that alum produces in the tanning of leather.

Aluminum is processed to cans, wiring and alloys. Aluminum salts are often added to water to start precipitation reactions for phosphate removal. Consequently, sewage sludge in water purification with a pH value between 6.8 and 7.3 is present as hydroxides. Alums are applied as fertilizer in tea plantations.

c)Using Natural water purification means: The most common natural means used in river water purification is a method known as Solar Water Disinfection or better known as SODIS. This method, as the name suggests, is the use of the sunrays to purify river water.

Aluminium Sulfate, Shortly known as Alum, when added to raw water reacts with the bicarbonate alkalinities present in water and forms a gelatinous precipitate. This floc attracts other fine particles and suspended material in raw water, and settles down at the bottom of the container.

In water purification, alum acts as a good coagulant. A coagulant binds extremely fine and small particles of impure water to large particles which are easily removable by filtration or settling. So, anyone can remove unwanted colour and turbidity from water.

As early as 2000 BC the Egyptians used almonds smeared around vessels to clarify river water. The use of alum as a coagulant by the Romans was mentioned in around 77 AD. By 1757, alum was being used for coagulation in municipal water treatment in England.

What is alum used for in water purification products?

To accomplish this, the water is treated with aluminum sulfate, commonly called alum, which serves as a flocculant. Raw water often holds tiny suspended particles that are very difficult for a filter to catch. Alum causes them to clump together so that they can settle out of the water or be easily trapped by a filter.
