Filter source on the red brown fused aluminum ferric chloride and light yellow polyaluminum chloride Difference between the filter source on the red brown polyaluminium chloride and light yellow polyaluminum ferric chloride differences in the first two days, Jingzhou, Hubei Yang manager asked me to plant aluminum polychlorinated ferroalum What is the difference between reddish brown and yellow, the production process is different, how to choose different colors of the product? According to this situation, the filter technology department immediately organize related articles, in order to many new and old customers to solve this confusion. There are two types of ferric chloride, such as reddish brown and yellow. Therefore, why the content of light yellow polyaluminum chloride is much higher than that of reddish brown polyaluminum chloride? The reason is the following: 1, the production of different quality materials, high content (30%) PAC ferric chloride is usually processed by aluminum hydroxide and hydrochloric acid. The reason why the polymerization of aluminum ferric chloride red, because there are different levels of ferrous ions rich, aluminum hydroxide powder is not iron, processed into aluminum ferric chloride will not be red, there is a pale yellow Color. 2, the processing is not the same, due to the addition of high content of PAC Ferric chloride filter, filter out the impurities during the color will be more and more shallow, aqueous solution after the water there will be bright state, so the lighter the color The higher the content of PAC, the less water insolubles (impurities).
