What's Coagulation In Water Purification?
Coagulation is an essential process in water purification that involves the addition of chemicals to destabilize and aggregate small, suspended particles in water, making them easier to remove. The coagulation process is typically the first step in water treatment and is followed by sedimentation, filtration, and disinfection.
The coagulation process involves adding a coagulant, such as poly aluminium chloride or ferric chloride, to the water. The coagulant works by neutralizing the electric charges on the particles, causing them to come together and form larger aggregates or flocs. These flocs settle out more easily during the subsequent sedimentation process, allowing for easier removal.
The effectiveness of coagulation in water purification depends on several factors, including the type and concentration of coagulant used, the pH of the water, and the nature and concentration of the suspended particles. The optimal conditions for coagulation vary depending on the specific characteristics of the water being treated.
Overall, coagulation plays a critical role in water purification by helping to remove suspended particles, including bacteria, viruses, and other contaminants, making the water safer for consumption.

Polyaluminium Chloride Applications
- Clarifying agent in wastewater
- Dewatering agent
- Coagulant for different industrial areas
Polyaluminium Chloride Advantages:
1. Its purifying effect on low-temperature, low turbidity, and heavily organic polluted raw water are much better than other organic flocculants, also the treatment cost is lowered by 20-80%.
2. It can lead to quick formation of floc (especially at low temperatures) with big size and rapid precipitation service life of cellular filter of the sedimentation basin.
3. The dosage is smaller than that of other flocculants, which is better for improving the quality of treated water.
4. It has wide-range adaptability to the waters at different temperatures (in the summer and the winter) and at different regions (in the south and the north of China).
5. It is suitable for the automatic dosing device of the alum.
6. It can adapt to a wide range of pH values (2-9) and can reduce the pH value and basicity after processing. Polyaluminium Chloride for Water Treatment chemicals can be used in many ways.
Polyaluminium Chloride Usage:
1. The user can allocate remedy concentration by test and determine the optimum dosage according to the differences from being added after they are dissolved and diluted.
2. The dilution ratio of the liquid product is 5-50% and the dilution ratio of the solid product is 2-20%.
3. The liquid product dosage is 3-40kg/1000 tons of water and the solid product dosage is 1-15kg/1000 tons of water.
4. The amount of specific dosing is based on coagulation tests and experiments.
