Those who are looking for an answer to the question «Why alum is used in purification of river water by plants?» often ask the following questions:

❔ Why alum is used in purification of river water?

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.

Alum is used to clarify water by neutralizing the electrical double layer surrounding very fine suspended particles, allowing them to flocculate (stick together). After flocculation, the particles will be large enough to settle and can be removed.

It is mainly used in municipal water treatment plants to treat wastewater and potable water. Aluminum sulfate is also important for lake treatment and restoration. Untreated wastewater and potable water have negatively charged suspended colloids, and water treatment systems use positively charged metallic salts, such as aluminum sulfate, to destabilize the colloidal particles.

The Alum Water Purification Process Alum is a double sulphate of potash and aluminium, and in this case breaks into potassium sulphate which remains in solution, and a basic aluminic sulphate. This basic sulphate of aluminium, the composition of which is undetermined, precipitates as a more or less gelatinous and flocculent mass, and carries down with it the foreign matters and humus bodies.

Alum is used in the form of Aluminum Sulfate (usually) to remove particulates in water through flocculation to remove solids and some ions and allow them to be filtered or settled. The process is part of a treatment process and, properly managed, leaves little of the chemical components in solution.

Primary coagulants neutralize the electrical charges of particles in the water which causes the particles to clump together. Chemically, coagulant water treatment chemicals are either metallic salts (such as alum) or polymers. Polymers are man-made organic compounds made up of a long chain of smaller molecules.

Ozone has been used in drinking water plants since 1906 where the first industrial ozonation plant was built in Nice, France. The U.S. Food and Drug Administration has accepted ozone as being safe; and it is applied as an anti-microbiological agent for the treatment, storage, and processing of foods.

Why alum is used in water purification?

purification

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… The alum promotes coagulation of fine particles which helps resolve problems of color as well as turbidity.
