To keep the storage tanks safe from mold, mildew, fungi, and microbial organisms, alumina fitkari in water tanks is used. It assists in elongating the container’s useful life by purifying water through flocculation (removing suspended solids). The combined particulates sink to the container’s bottom and removed thereafter.
For centuries, alum fitkari in water tanks has been acknowledged as a product with multiple advantages:
- Used as a mordant and preservative
- For ailments, such as respiratory issues
- As astringents in medicine
- In fire extinguishers

Use of Aluminum Sulphate in Water Tanks
Aluminum Sulphate (Iron-free) is beneficial for treating municipal water. It aids in the elimination of microscopic particles that are difficult to filter. Following are some reasons as to why alum is a preferred choice.
Coagulation & Flocculation
Alum is an effective particle binder. When added to water, it reacts with impurities such as suspended solids, organic matter, and certain metals, causing them to clump together and form larger particles called flocs. These flocs settle at the tank’s bottom and removed during the treatment process.
Reduction in Turbidity
Turbidity refers to the cloudiness or haziness of water caused by suspended particles. However, due to variations in stream energy and solid composition, the relationship between turbidity and solids can change accordingly. Moreover, the coagulant dosage also matters: Alum helps to reduce it considerably. According to a study, alum was tested on turbid water (90-130 NTU). The pH of the solution was (6-7.4) for different doses: 10 mg/l and 20mg/l in 250ml solvent.
The results were positive and encouraging: The coagulation process removed 46.15% of turbidity from the mixture. Individuals and businesses can find fruitful outcomes from this experiment. In other words, they can apply the same process to check the turbidity in water treatment facilities.
Phosphate, another unwanted material in water, is the root cause of the ‘green effect’. It can be removed by using alum. Phosphates contribute to the growth of algae and other undesirable microorganisms in water tanks. Alum reacts with phosphates, forming insoluble compounds that can be removed during the treatment process, thereby reducing the nutrients available for the growth of organisms.
Alum has the ability to lower the pH of water, making it more acidic. In some cases, adjusting the pH of water may be necessary to facilitate certain treatment processes or inhibit the growth of specific microorganisms. By incorporating alum into water tanks, the pH can be controlled within the desired range.
It’s worth noting that the specific application and dosage of alum can vary depending on the water quality and treatment objectives. Professionals assess the water composition and conduct tests to determine the appropriate alum dosage for effective treatment in water tanks.
Properties of Alum
Alum is a non-toxic substance having moderate water solubility. It has astringent and antibacterial properties; it can negatively affect the growth of pathogens like Vibrio Cholerae, Shigella Dysenteriae and more. Following are some common attributes of alumina:
Alum is a double salt composed of a combination of a monovalent cation (such as potassium, K⁺) and a trivalent cation (such as aluminum, Al³⁺). It also contains sulfate ions (SO₄²⁻) and water molecules (H₂O).
Astringent & Antiseptic Properties
Alum is well-known for its astringent properties, which make it useful in various applications. It can cause a tightening or puckering sensation on the skin and mucous membranes due to its ability to contract tissues. Alum has antiseptic properties too. It is used as a topical treatment for minor cuts and wounds.
Alum has the ability to adjust and stabilize the pH of a solution. It can act as a buffer, helping to maintain a desired pH level in various applications.
Alum is used as a flocculants in water treatment processes. It can cause impurities in water to clump together, facilitating their removal during filtration.
Potassium alum is approved as a food additive (E number E522) and is used in some food preparations, such as pickles and baking powder. It serves as a stabilizer and can help maintain the firmness of fruits and vegetables.
