The amount of alum needed for water purification typically ranges from 10 to 50 grams per 1000 liters of water, depending on the water quality and turbidity. For most applications, starting with around 20 grams is common, and adjustments can be made based on the specific conditions and results observed. It's essential to conduct tests to determine the optimal dosage for effective purification.
Purification of muddy water by alum is due to the process of coagulation, where alum causes suspended particles in the water to clump together and settle to the bottom, making it easier to remove impurities. This process improves the clarity of the water by removing suspended solids and turbidity.
Alum is used in vaccines as an adjuvant. Alum is commonly used as a coagulant in water treatment. And its used for domestics water.
Potash alum is used in the purification of water because it acts as a coagulant, helping to attract and bind together impurities such as suspended particles, microorganisms, and pollutants. This process forms larger particles that can more easily be removed through filtration, sedimentation, or other water treatment methods, resulting in cleaner and safer drinking water.
Alum is called "फिटकरी" (fitkari) in Hindi. It is commonly used for various purposes in traditional Indian households such as water purification, skincare, and pickling.

alum when mixed with water produces H2S gas which is highly toxic . although this is a gas and is released in air but some of it gets dissolved in water to produce H2SO4 acid and makes the water acidic. alum treated water needs more treatment through conventional water purifirs to remove any traces of H@S and H2SO4
In rural Bangladesh, still many people use open water (e.g. river, pond, creek, fountain etc.)for drinking. Some of them drink this open water without purification. But some people use alum (Fitkari is Bengali word) for purification. This purification system is also very popular in Bangladesh. This method widely accepted as purified water although it is not proved that this method can actually kill all bacteria. But after putting alum in water it looks clear. It means that turbidity in water improve a lot but a significant number of bacteria survive within that water.Prepared by: Hannan HiswasDhaka, Bangladesh24 May 2012
No, sodium bicarbonate (baking soda) and alum are not the same. Sodium bicarbonate is a white powder used in baking and cooking, while alum is a chemical compound typically used in food processing, water purification, and as a pickling agent.
Ferric alum contains iron, which gives it a yellow color, while non-ferric alum does not contain iron and is typically colorless. Ferric alum is commonly used in water purification and wastewater treatment processes, while non-ferric alum is used in industries like paper manufacturing and tanning.
Alum in small amounts is generally safe for consumption, but ingesting large quantities can be harmful, causing nausea, vomiting, and stomach pain. It is important to use alum in cooking or pickling in recommended quantities.
Re-rocking alum involves crushing the alum crystals into a fine powder and then mixing it with a binding agent, often using water, to reform it into solid blocks. The mixture is then pressed into molds and allowed to dry completely before being used again. This process helps restore the alum's usability for various applications, such as in water purification or as an astringent. Always ensure safety measures are followed, as handling chemicals can pose risks.
