Understand the process of polyaluminum chloride in tap water process Understand the polyaluminum chloride process in tap water polyaluminum chloride plays a decisive role in the tap water treatment, Of polyaluminum chloride, polluted water and industrial polluted aluminum chloride is not the same, polluted water polyaluminium chloride used raw materials are: aluminum hydroxide powder production process is: frame filter press or spray-drying type, and Polychlorinated industrial wastewater treatment raw materials are: calcium aluminate, the production process is: (roller technology) natural precipitation. Polyaluminum chloride water treatment aluminum content is generally 29% -31%, water insoluble in less than 0.6, the basic degree of 40-90 between the salt, followed by the most important indicator is that the content of heavy metals can not be higher than GB15892 -2009 indicator. The industrial wastewater polyaluminium chloride content of aluminum oxide is generally about 28%, about 1.5 insoluble in water, the basicity of 95 in between, for the content of heavy metals without tap water treatment with aluminum chloride indicators as strict, Iron content requirements of 5 or less, arsenic content of 0.0015, lead content requirements below 0.006. Overall in line with industrial grade Poly aluminum chloride national standard GB / T22627-2008 standards can be. Tap water is the most common water in our daily life, then it is through what process to our home, it is estimated that few people know. Today, let's take a look at the flow of tap water. First of all, the source water must be extracted from rivers and lakes to the waterworks (different water intakes in different areas directly affect the quality of drinking water in an area); then, after precipitation (at this time, tap water will be treated with polychlorinated Aluminum), filtration, disinfection, warehousing (reservoir), and then by high pressure water pump input into the water pipe, and now the state regulations to use PP pipe, rather than the previously used iron pipe, pipe over time will rust, Will cause serious secondary pollution; the final diversion to the user leader. The whole process to go through several water quality tests, in some places but also after secondary pressurization, secondary disinfection to enter the user's home. Polychlorinated tap water treatment products have little corrosive, such as accidentally splashed on the skin, rinse immediately with water. Production and use of this product to wear workers wear overalls, wearing masks, gloves, wearing long rubber boots. Production equipment to be sealed, workshop ventilation should be good. Pollution-free tap water treatment products with no danger of explosion and explosion, do not belong to the scope of dangerous goods.
