China top quality High purity PAC use for water treatment good efficiency suppliers
Product Description
High Purity Polyaluminum chloride (PAC) is an inorganic polymer coagulant, also known as high-efficiency polyaluminum chloride or high-efficiency spray-drying polyaluminum chloride. It is between AlCl3 and Al(OH)3. It is a water-soluble inorganic polymer with a general chemical formula of [Al2(OH)nCl6-n]m, where m represents the degree of polymerization and n represents the PAC product. Neutral degree. When n=1~5, it has a Keggin structure of highly charged polymeric ring chain, which has a high degree of electrical neutralization and bridging effect on colloids and particles in water, and can powerfully remove micro-toxic substances and heavy metal ions.

Application Areas
Polyaluminum chloride (PAC) is an inorganic polymer coagulant that is widely used in the field of water treatment. It can effectively remove impurities such as suspended solids, colloidal substances and organic matter in the water, clarifying and improving the water quality. Polyaluminum chloride is not only used in municipal sewage treatment, but also widely used in drinking water treatment, industrial wastewater treatment, papermaking, printing and dyeing, petrochemical industry and other fields.
During the water treatment process, polyaluminium chloride electrically neutralizes and bridges colloids and particles in the water through its highly charged polymer ring chain, forming flocs and precipitating, thereby achieving solid-liquid separation. Its advantages include high active ingredients, low dosage, convenient transportation and storage, excellent flocculation performance, and good stability.
In addition, polyaluminum chloride can also be used as a decolorizing agent to remove the color of printing and dyeing wastewater, and is especially suitable for treating fluorine-containing wastewater, high turbidity water, and low-temperature low-turbidity water. In the paper industry, it can be used as a precipitant for pulp to improve paper quality and strength.
Avoid mixing with other chemicals: When storing and using, avoid mixing with other chemicals to prevent chemical reactions.
Wear protective equipment: Please wear gloves, goggles and other protective equipment before use to avoid direct contact with skin and eyes.
Adjust the pH value: Before using polyaluminium chloride, the pH value should be adjusted according to the water quality to obtain the best results.
Stirring and mixing: After using polyaluminum chloride, sufficient stirring and mixing should be carried out to ensure that the agent fully contacts and reacts with the pollutants in the water.
Pay attention to storage conditions: Polyaluminum chloride should be stored in a dry, ventilated place to avoid moisture and high temperature.
FAQ
Regarding packaging: Product labels and packaging will be updated in due course. The specific packaging will be subject to the actual goods received, or you can contact the customer to obtain the current packaging diagram.
Are you a factory or a trader?
We are a trader, but we have cooperative factories that provide stable supply, especially sodium hydroxide and sodium sulfide. We are the exclusive agent in southern China and have certain advantages in channels and prices. At the same time, if you need other chemical products, we can also Finding a suitable factory for you to cooperate with will not limit you to one factory providing a single product.
Are your prices the lowest?
Maybe the price you see on the product interface is fixed and different from other companies. However, the prices of products in the chemical industry will change frequently. We can only say that we can provide you with high-quality supply as much as possible. Lowering the price, of course, is also related to the quantity you purchase. You can consult customer service for the latest product prices.
How to transport?
For chemical products, we generally transport them by sea by full container. If the quantity you purchase does not meet the full container requirements or special products, we will combine them with other goods or pack the special chemicals separately. The packing method can be confirmed after placing the order.
How long does it take to deliver to my country or address?
Our company's warehouse is in Guangzhou, China, close to Nansha Port and Shenzhen Bay, so it will be shipped by sea from these two ports first. The delivery time depends on your distance from the port. Southeast Asian countries usually take about 5 days, and Oceanian countries usually In about 10 days, it depends on the shipping company, I can make further confirmation based on your address after you place the order.
Are the quality of your products stable?
Because we are a trading company, we cooperate with large-scale factories in China. Before cooperating with them, we will purchase samples and inspect the factories. Only products with stable product quality that comply with national regulations can enter ours. In the product list, we will conduct an additional inspection for the exported goods, and any products that do not meet the standards will be rejected by us.
If I purchase a large quantity, can I get any additional discounts?
Regarding large customers, we have more favorable prices, but based on different chemicals, you need to consult customer service to get the latest quotation.
