How to use polyaluminium chloride to treat drinking water

Polyaluminum chloride is the most widely used water purifying agent in water treatment of water supply companies. China's drinking water mainly uses water from the Yellow River, the Yangtze River and reservoirs. Due to the large sediment content and large treatment capacity, polyaluminum chloride is required to accelerate sedimentation to improve treatment efficiency. Although the water in the waterworks belongs to low turbidity water, the purification requirements for water quality are high, so the general polyaluminum chloride is difficult to meet the treatment standards.

Next, we will introduce which polyaluminum chloride should be used and how to use it. The raw material of polyaluminum chloride for tap water treatment is aluminum hydroxide powder, and the production process is plate and frame filter pressing or spray drying. We all know that tap water is people's drinking water, and the state has clear regulations and indicator requirements for drinking water treatment. Now, let's understand the standards for drinking water treatment and the requirements for handling drinking water products.

Why must the waterworks use 30% aluminum chloride?

30% content of polyaluminum chloride is processed from aluminum hydroxide powder and calcium powder. Compared with ordinary industrial polyaluminum chloride, it has the characteristics of low heavy metal content, less deposition, clear and transparent chemical water, and was generally used as a medicament before. With the improvement of people's requirements for water quality and attention to the environment. The drugs containing polyaluminum chloride 30 produced by Hongyuan strictly conform to the national standard GB15892-2009. For polyaluminum chloride, its process, raw materials and uses are different.

Of course, the most commonly used are 28% aluminum oxide (PAC) for sewage treatment and 30% aluminum polychloride for drinking water treatment. The application effect of 30% polyaluminum chloride is better. Even if the water looks clear, 30% polyaluminium chloride can still remove impurities. The same is true for normal sewage treatment. According to the turbidity of sewage, water with high turbidity is suitable for low content of polyaluminum chloride. The treatment is not completely clean, but the cost is low. Water with low turbidity needs cleaner treatment!
