As the operator of the online shop ChemMarkt.de, we are proud to offer our customers a wide range of high-quality chemical products for household and industrial use. One of these products, which plays a crucial role in water treatment, is aluminum sulfate.

What is aluminum sulfate and how does it work?

Aluminum sulfate, also known as alum, is a chemical compound consisting of aluminum, sulfur, and oxygen. In water treatment, it is used as a coagulant to remove suspended solids, colloids, and other impurities from water.

The process works as follows: When aluminum sulfate is dissolved in water, it dissociates into aluminum ions (Al³⁺) and sulfate ions (SO₄²⁻). These ions then react with the negatively charged particles in the water, such as clay, silt, or organic substances. This forms larger, less soluble flocs that sink or can be easily filtered out.

This process is called coagulation. It is followed by sedimentation, where the flocs settle at the bottom due to their size and density. Finally, the particles can be removed from the water by filtration.

Applications of aluminum sulfate in water treatment

Aluminum sulfate is used in various areas of water treatment:

Drinking water treatment

In drinking water treatment, aluminum sulfate is used to remove suspended solids, colloids, and organic impurities from raw water. This makes the water clearer and more hygienic before it enters the distribution system.

Wastewater treatment

Aluminum sulfate also plays an important role in wastewater treatment. It is used here to remove phosphates, heavy metals, and other pollutants that may be present in industrial or municipal wastewater.

Industrial water treatment

In industrial processes such as paper manufacturing, textile processing, or metalworking, aluminum sulfate is used to remove impurities from process water. This allows the plants to operate efficiently and reduces environmental impact.

Swimming pool water treatment

Aluminum sulfate is also used in swimming pools. It serves to remove suspended solids, bacteria, and other impurities to ensure water quality and hygiene.

Advantages of aluminum sulfate in water treatment

Aluminum sulfate offers a number of advantages in water treatment:

High efficiency

Aluminum sulfate is a very effective coagulant that delivers high cleaning performance even at low concentrations.

Cost-effective

Compared to other coagulants, aluminum sulfate is a relatively cost-effective product, which increases the economic efficiency of water treatment.

Easy handling

The dosing and application of aluminum sulfate in water treatment plants is straightforward and requires only minimal effort.

Environmentally friendly

Aluminum sulfate is a natural mineral and is considered environmentally friendly. It helps reduce the pollution of water bodies by contaminants.

Versatile applications

As already mentioned, aluminum sulfate can be used in various areas of water treatment – from drinking water treatment to wastewater purification.

Safety aspects when using aluminum sulfate

Although aluminum sulfate is considered relatively harmless, some safety aspects must be observed during handling and storage:

• Aluminum sulfate is an irritant that can cause irritation upon skin contact, eye contact, or ingestion. Therefore, wearing protective equipment such as gloves and safety goggles is recommended.
• During storage, care must be taken to keep aluminum sulfate dry and protected from moisture, as it can otherwise clump.
• When handling aluminum sulfate, good ventilation must be ensured, as sulfur dioxide can be released when dissolving the salt.

By observing these safety instructions, aluminum sulfate can be used safely and effectively in water treatment.

Conclusion

Aluminum sulfate is an indispensable product in modern water treatment. Whether in drinking water treatment, wastewater purification, or industrial processes – aluminum sulfate convinces with its high efficiency, cost-effectiveness, and environmental compatibility.
