Aluminum sulphate for water treatment is an important water purifying agent. Due to its extremely low iron content, it can prevent problems such as abnormal color, odor, or excessive iron ions in the treated water, playing a crucial role in drinking water purification.
Aluminum Sulphate For Water Treatment Application Advantages
Aluminum sulphate for water treatment has excellent purification effect: It can effectively remove suspended impurities, colloids, some bacteria and viruses from water, and improve water clarity.
The usage dosage of Aluminum sulphate for water treatment that complies with national standards, the residual concentration of aluminum ions is low, and it has a relatively small impact on human health Lower cost.Compared with other coagulants (such as polyaluminum chloride), Aluminum sulphate for water treatment is relatively cheaper and suitable for small and medium-sized water plants or scenarios with limited budgets.
Aluminum sulphate for water treatment has strong adaptability: It has certain treatment capabilities for different water qualities (such as low-temperature and low-turbidity water), and the operation is relatively simple.

Aluminum Sulphate For Water Treatment Usage Precautions
Dosage Control
The optimal dosage should be determined through experiments based on the quality of the raw water (such as turbidity, pH value, etc.). Excessive dosage may lead to excessive residual aluminum ions in the water or generate a large amount of sludge, increasing treatment costs.
pH Value Adjustment
Aluminum sulphate coagulation effect is significantly influenced by the pH value of the water. The optimal pH range is usually 6.5 to 7.5. If the pH value of the raw water deviates from this range, acids or bases (such as lime or sulfuric acid) should be added in advance for adjustment.
Storage and Transportation
Aluminum sulphate should be stored in a dry and well-ventilated warehouse to prevent moisture and caking. During transportation, it should be protected from rain and packaging damage.
Residual Detection
The treated water should be regularly tested for residual aluminum ion content to ensure compliance with drinking water standards.
Aluminum sulfate mainly used in water treatment,besides Aluminum sulphate for water treatment also used in paper industry pulp sizing agent, oil industry used as clarifying agent, petroleum industry used as deodorant decolorizing agent, cement coagulant, textile industry, fire protection field, catalyst carrier, and other chemical raw materials to prepare aluminum salt and titanium dioxide, soil amendment, pigment manufacturing, etc.
