Polyaluminum chloride and aluminum chloride with the same sewage treatment agents, often silly customers to tell the two silly, they think it is because the pH of the polymer is alkaline, it is not true, net Water materials manufacturers (+ 86-15639065815) to answer this, people used to use recycled waste, especially aluminum ash production is called basic aluminum chloride, the color is black, most of them are used to deal with quartz sand factory mines Wastewater, because of the high basicity of the salt, is more effective in treating industrial wastewater with greater hardness, while yellow or reddish brown aluminum chloride is commonly referred to as polyaluminum chloride, ie, PAC and PAC standards stipulate that PH 3.5 - 5, close to neutral, for aluminum chloride and aluminum chloride What is the difference, the following, by the filter water purification materials manufacturers summed up the following, for your reference:
1 Basic letter
Abbreviation PAC, Alkaline Aluminum Chloride Abbreviation: BAC
Color Status: Polyaluminum Chloride is yellow, tan powder; Basic Aluminum Chloride is black powder
2 , The production of raw materials are different:
PAC is made of calcium mixed with hydrochloric acid, basic aluminum chloride is the use of industrial aluminum slag and aluminum ash and activated bauxite as raw materials after polymerization, because the use of Different raw materials, the price of polyaluminum chloride is greater than the basic aluminum chloride.
3, using a different range:
PAC is based on the basic aluminum chloride developed more widely used products, widely used in industrial wastewater, domestic water, ceramic wastewater, printing and dyeing wastewater , Basic aluminum chloride is mainly used in industrial wastewater, paper water, printing and dyeing water, in the treatment of paper, printing and dyeing wastewater has a unique performance.
