What are the advantages of polyaluminum chloride food grade in water treatment

Food grade Polymeric Aluminium Chloride is the top-notch product in the polyaluminum chloride series, suitable for various food and reagent additives, papermaking and chemical industries, and highly praised by customers!

Food grade polyaluminum chloride is also known as high-purity iron free white polyaluminum chloride. Its primary raw materials are high-quality aluminum hydroxide powder, hydrochloric acid, refined through a variety of complex processes such as spray drying. Food grade polyaluminum chloride is mainly used for food loosening, food coloring and flavor enhancement. Because it is a direct additive, it has very strict *ments on manufacturing process and production hygiene standards. So, what are the advantages of food grade polyaluminum chloride compared to industrial grade polyaluminum chloride? Below, the manufacturer of billions of liters of polyaluminum chloride will lead you to learn more.

Advantages of food grade Polyaluminum Chloride compared to general polyaluminum chloride:

1. AL2O3 content high>29.5%

2. The color is pure, and the aqueous solution of this product after hydration is clear and without any color, while the color of the general polyaluminum aqueous solution may turn yellow or brown.

3. Water insoluble substances are small, only 0.3%, while general polyaluminum has more than 2%.

4. The alkalinity is low, only 50%, while the alkalinity of polyaluminum is generally around 90%.

5. The color is pure white and clean, without any other metal elements except for aluminum. After the product is hydrated, the color of the aqueous solution is clear and without any color, while the color of water treated with general polyaluminum chloride may turn yellow or brown.

6. Low iron content, with the characteristic of being easily soluble at low temperatures.

7. The product is mainly used in daily water supply, industrial water supply, oilfield reinjection water, circulating cooling water, and other aspects.

Food grade Polychlorinated Aluminum is thoroughly polymerized through deep processing and can be directly used in industries such as food and industry. Its price is also much higher than industrial grade polyaluminum chloride. Industrial grade polyaluminum chloride is primarily used for oil production and industrial wastewater treatment, and cannot be used as a food additive. Otherwise, it will cause serious harm such as food! When choosing food grade polyaluminum chloride, we must also keep our eyes open and avoid unnecessary loss if we purchase lower quality food grade polyaluminum chloride due to its affordability!
