Methods to use and features of Polyaluminum Chloride

Determine the dosage according to the water quality.

1. The dosage is different depending on the water to be treated. Generally, the dosage for water purification is about: 5-100 g/ton for liquid products, 20-25 kg/thousand tons for solid products (in terms of commodities), which can pass the beaker test Decide. 

2. The preparation can be directly added to the water, and the amount of water added can be determined according to the dosage and the amount of treated water. After adding water, it should be stirred evenly.

Features: 

1. Polyaluminum chloride is mainly used for the purification of drinking water and industrial water supply, as well as the treatment of industrial wastewater. It is a flocculant widely used in the treatment of domestic water supply and industrial water supply. 

2. Polyaluminum chloride has the advantages of good flocculation, large alum, low dosage, high efficiency, fast sedimentation, and wide application range. 

3. Polyaluminum chloride can be used at low temperature, the suitable PH value is 5-9, no alkali is needed after dosing, the flocculation effect is good, and the sludge production is low. 

4. The effective dosage of polyaluminum chloride products is 20-50mg/L. The liquid product can be metered and dosed directly, and the solid product needs to be prepared into a 10%-15% solution in the dissolution tank, and then metered and dosed according to the required concentration. 

5. Polyaluminum chloride products can also be used to remove iron, manganese, chromium, lead and other heavy metals contained in water, as well as fluoride and oil in water, so it can be used to treat various industrial wastewater. 

6. Polyaluminum chloride products are highly adaptable to treated water, especially for high turbidity water; the stable coagulation effect can still be maintained when the water temperature is low. 

7. After the use of polyaluminum chloride to purify the water, the chroma and the content of heavy metals such as iron and manganese are low, and the corrosion effect on the equipment is small. 

8. When polyaluminum chloride is used, uneven mixing will occur, and it can be added after dilution. 

9. Polyaluminum chloride can be combined with weak cationic polyacrylamide and combined with aluminum sulfate or ferric chloride for sludge preparation.
