Coagulant is a chemical substance commonly used in the treatment of water and wastewater. It can promote the rapid aggregation of small particles suspended in water to form larger clumps, which facilitates subsequent sedimentation and filtration treatment. Coagulants play an important role in purifying water quality, removing suspended and sediment, and purifying wastewater.
Nature:
1. It is a colorless or light yellow liquid or powder with strong coagulation effect.
2. It has good miscibility and can quickly combine with suspended particles in water to form large clumps.
3. The main features include fast coagulation speed, small dosage and processing cost, and wide applicability.
Usage:
1. Used in fields such as water treatment engineering, sewage treatment plants, and wastewater treatment in industrial production processes.
2. Used to remove suspended solids, colloidal substances, chromaticity, heavy metal ions, etc. from water, thereby improving water quality and sewage treatment efficiency.
Method:
This generally includes synthetic chemical methods and extraction methods for natural minerals. The synthesis method is to prepare coagulants through chemical reactions, usually requiring raw materials such as aluminum chloride and iron chloride, and then synthesizing coagulants through the reaction. The natural mineral extraction method involves extracting active components of coagulants, such as aluminum silicate and iron sulfate, from natural ores.
Security information:
1. When using, it should be added according to the prescribed dosage to avoid water pollution caused by excessive use.
2. Proper use and handling of coagulants are crucial for human health and environmental safety.
3. During storage and use, attention should be paid to preventing contact with skin and eyes, and not inhaling dust or swallowing.
4. The solid waste of coagulants after wastewater treatment also needs to be properly treated to avoid environmental pollution.
5. During use, relevant safety regulations and operating procedures should be strictly followed.
