Polyaluminium chloride has two kinds of solid and liquid. Today, we talk about spray polymerization aluminum chloride in solid polyaluminium chloride. Solid polyaluminium chloride is made from liquid polyaluminium chloride by means of drum drying or spray drying technology. The polyaluminium chloride produced by different drying processes is also very different.

 

The roller drying process of polyaluminum chloride is to dry the liquid polyaluminum chloride slowly by high temperature roller, and finally get solid powder polyaluminum chloride. The process of this kind of drying process is simple and the production cost is low. The corresponding polyaluminum chloride produced by this kind of production process has some disadvantages, such as more impurities, high content of water-insoluble substances, and the color is generally brown yellow. It is one of the production processes of polyaluminum chloride used by many manufacturers at present. Polyaluminum chloride produced by roller drying process is usually used for the treatment of industrial sewage and urban sewage, and its low price is chosen by people.

 

The spray drying process of polyaluminum chloride is through spray drying tower to dry liquid polyaluminium chloride in fog form, and then to produce non very fine powdery solid. The polyaluminium chloride produced by spray drying process has less impurities, less insoluble matter, and quick hydrolysis, and its color is usually yellow or golden yellow. At present, drinking water grade polyaluminium chloride and food grade polyaluminium chloride are produced by spray drying process. The spray drying process is more complicated than that of the drum drying process, and the price is higher than that of the drum type polyaluminium chloride.

 

Lvyuan Environment Group Co.,Limited as a manufacturer of polyaluminum chloride, the company has drum polymerized aluminum chloride and spray polymerization aluminum chloride.
