What is the difference between industrial grade polyaluminium chloride and drinking water grade polyaluminium chloride?
Polyaluminum chloride is divided into industrial grade and drinking water grade according to its different uses. What is their direct difference? Today, polyaluminum chloride manufacturers will explain to you the following industrial grade polyaluminum chloride anddrinking water grade polyaluminium chlorideThe difference.
Generally speaking, products with industrial grade three words are generally cheaper than drinking water grade, and polyaluminium chloride is no exception. Here again with everyone under popular science, not with drinking water grade words can be directly eaten, especially chemical products. Many people think that drinking water level is directly drinking water, otherwise what is the drinking water level. In fact, the meaning of drinking water level is not literally understood,drinking water grade polyaluminium chlorideIt is corrosive in itself. It is said that it is drinking water grade, which is relative to industrial grade. Generally, industrial grade polyaluminium chloride does not require so high water quality after treatment. It is possible that the water quality after treatment has reached the national emission standard, but it is far from reaching the drinking standard. The control of drinking water in our country is very strict, especially the content of harmful substances such as heavy metals. This is the difference between industrial grade and drinking water grade. Industrial-grade polyaluminium chloride is mainly aimed at sewage that can meet national discharge standards after treatment, whiledrinking water grade polyaluminium chlorideIt is mainly used to treat drinking water and pharmaceutical, chemical and other water treatments that require high water quality.
relatively speaking,drinking water grade polyaluminium chlorideThere are strict requirements for all impurities in the treated water, so the harmful substances contained in the product itself cannot exceed the standard. Therefore, drinking water grade polyaluminum chloride is much higher than industrial grade in terms of raw materials and quality and production quality control. Polyaluminum chloride, this is why the price of drinking water grade polyaluminum chloride is higher than that of industrial grade. On the one hand, the cost of raw materials is high, and on the other hand, better quality control and production technology are required.
