As a new type of high-molecular flocculent and coagulant, poly aluminum chloride is widely used in the water treatment industry. With the upgrading of products and the improvement of technology, it is not only widely used in the sewage treatment industry, but also widely used in the tap water treatment in recent years.
S How to distinguish between good and bad poly aluminum chloride? If users want to purchase qualified poly aluminum chloride products, it is necessary to pay attention to the following points:
First of all, from the production process, the polymerization of aluminized chlorine is usually divided into two types: drum drying type poly aluminum chloride (traditional process) and spray drying type poly aluminum chloride (new process). The drum drying type poly aluminum chloride production process is very simple, and the appearance of product is yellow-brown to golden yellow particles. The content of the active ingredient AL2O3 is between 18%-28%, and the water insoluble matter is between 8% and 1.5%. Generally, the darker the color, the lower the content, and the higher the insoluble matter. Spray-drying poly aluminum chloride adopts a new drying and pressure filtration process. The fineness is as delicate as milk powder and it is very soluble. According to different raw materials, the color is divided into white and light yellow, and the water soluble is between 0.1-1.5%.
So how do you distinguish between the two products? This is very simple, and can be achieved by visual inspection. The appearance of the drum-dried poly aluminum chloride is granular, and the spray-dried poly aluminum chloride has a powdery appearance and a light color.
In the face of many brands, types and models of products on the market, how can customers identify the quality of the products?
1: If your equipment is in condition, through the laboratory analysis, the higher the content of active ingredient AL2O3, the lower the water insoluble, the lower the heavy metal content, the better the product.
2: If the conditions are not convenient for testing, you can perform a solution test to make a simple distinction between the color and clarity of the liquid. First, prepare several beakers, simple scales, stir bars (glass rods or other alternatives); second: dissolve according to the ratio of water to chemicals, 2:1. For example: 100 grams of water, add 50 grams. The agent is stirred and dissolved. During the dissolution process, the dissolution rate is compared. After dissolving, it is allowed to stand for 15 minutes. The color and clarity are observed. The lighter and clearer the color, the less the product impurities, the higher the content and the lower the heavy metal, the higher the product grade.
Of course, the best product is not always suitable for all the customers. As our company, it is our ultimate goal to select the most cost-effective products for our customers and satisfy all needs of our customers. Nevertheless, different water quality and water treatment process require different products, how to choose the right product, please pick up your phone to contact us for sales, give us a detailed introduction of your situation, we will recommend the best and most economic products according to your specific situation. Or, please leave a message about your contact information, we will contact you the first time.
