Polyaluminium chloride is a kind of water purification material and an inorganic polymer coagulant. It is also referred to as polyaluminum, abbreviated as PAC. Molecular weight produced by the bridging action of hydroxyl ions and the polymerization of multivalent anions (highly charged inorganic polymers, water treatment chemicals). It can be divided into solid and liquid in form. Solids can be divided into Tan, beige, golden yellow and white (hydroxyl polyaluminium chloride) according to different colors. The liquid can be colorless and transparent, light yellow, light yellow to tan.
There are also great differences in the application and production technology of polyaluminium chloride with different contents. There are different use methods for different water quality and water treatment requirements. The correct use method can achieve a more reasonable dosage and achieve the purpose of water treatment. Sometimes, it is necessary to combine other water treatment agents to achieve better results.
Source water treatment of high and medium turbidity:
Function: the product is suitable for treating all kinds of high turbidity and medium turbidity water, especially the purification of high turbidity water. It has the advantages of fast formation, large precipitation, easy precipitation, wide pH range, suitable raw water, low corrosivity and low labor intensity.
Polychloride dilution method:
1. Dissolve the solid product in the liquid in the ratio of 1:3 with water, and then add water 10-30 times to dilute it to the required concentration and use it.
2. The dosage can be determined according to the different turbidity of raw water, and the better dosage can be determined. Generally, when the turbidity of raw water is 100-500mg / L, the dose per 1000 tons is 10-20kg.
Aluminum chloride solution is prepared into drinking water according to the weight of industrial water purification products, and 3-5-grade purified water products are purchased according to the need
1. Polyaluminium chloride is mainly used for drinking water purification, industrial water supply and industrial wastewater treatment.
It is the most widely used flocculant in domestic water supply and industrial water treatment.
2. Polyaluminium chloride has the advantages of good flocculation, large alum, low dosage, high efficiency, fast sedimentation and wide application range.
3. Polyaluminium chloride can be used at low temperature. The appropriate pH value is 5-9. There is no need to add alkali after addition. It has good flocculation effect and less mud production.
4. The effective dose of polyaluminium chloride product is 20-50mgl. Liquid products can be measured and added directly. After it is made into 10% - 15% solution in the dissolution tank, the solid product must be measured and added at the required concentration.
5. Polyaluminium chloride products can also be used to remove iron, manganese, chromium, lead and other heavy metals in water, as well as fluoride and oil in water. Therefore, they can be used to treat various industrial wastewater.
6. Polyaluminium chloride PAC products have strong adaptability to treated water, especially for water with high turbidity. When the water temperature is low, the stable coagulation effect can still be maintained.
7. Polyaluminium chloride is used to purify water after color and iron. The content of heavy metals such as manganese is low and has little corrosion effect on the equipment.
8. When polyaluminium chloride is used, there will be the problem of uneven mixing, which can be added after dilution.
9. Polyaluminium chloride can be used in combination with weak cationic polyacrylamide and aluminum sulfate or ferric chloride to prepare sludge. Small scale experiments should be conducted before using polyaluminium chloride
