❔ How to use alum in water purification water?

Alum in its powdered form can be added to water to bind with phosphorous particles to aid the water purification process. Pour eight-tenths of a gallon of contaminated water into the reaction vessel -- a sturdy glass container. Be sure that there is enough space in the vessel that the contaminated water can be stirred without spillage.

Alum is a coagulant that helps to settle down all floating suspended solids & colloidal substances present in the water. During rainy seasons the turbidity of raw water increase due to the presence of mud & other impurities due to heavy run off.

Aluminum sulfate serves as a coagulant and flocculating agent in water treatment, making the water easier to clean. 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.

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.

There are numerous ways to use alum as a flocculant, including to crush it into a powder before adding it to water, stirring and decanting or stirring the whole stone in the water for a few seconds and waiting for the solids to settle. The benefits of alum are that it is widely available, is proven to reduce turbidity, and is inexpensive.

Alum is an amazing and cheap way to purify water and soften hard water. Impurities found in the water are charged colloids and since they all have the same charge (positive), they repel each other and stay separate. Also since the particles are tiny the gravitational force acting on them is not strong either so they never settle down.

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.

Coagulation is carried out for the filtration and purification of water. Types of coagulants used in water treatment process. 1.Aluminium coagulants. Aluminium sulphate is the most widely used aluminium coagulant. It is available in a number of solid grades such as block, kibbled or ground and is also available as a solution. In waterworks practice aluminium sulphate is frequently but incorrectly referred to as ‘alum’.

Boiling water though has been the oldest way of purifying water. Even at home, this is being practiced since this is the most effective way of getting rid of micro-organisms in water. What we do at home is put a rubber or used cloth then encircle it to the water hose. The best way to purify your water, however, is using the Berkey Water Filter System. At the safety of your home, you can now filter and purify drinking water to its clearest and purest state.
