What is the difference between yellow polyaluminium chloride and white polyaluminium chloride?

Yellow polyaluminum chloride and white polyaluminum chloride, as the two major mainstream water purifiers, are quite similar in function and application, and their use methods are no different, but they show a significant watershed in the market price. The price difference is as high as more than doubled. Behind this phenomenon, in fact, contains multiple factors and considerations.

First of all, when it comes to yellow polyaluminium chloride, its color is not as pure as white, but it shows a unique advantage in practical applications. Good quality yellow poly aluminum, in the dissolution process, if the quality is high, will show a clear and colorless liquid state, even if the quality is slightly lacking, after dissolution is only slightly yellow, this slight color change does not affect its water purification efficiency. Part of the reason why yellow polyaluminum has a comparative advantage in price is that its alumina content is usually stable between 25% and 30%, which not only ensures good water purification effect, but also controls production costs. In addition, its salinity is generally as high as 80 or more, this feature makes yellow polyaluminum in all kinds of sewage treatment scenes can be easily, especially when used in conjunction with amide and other additives, its effect is more complementary, further improve the treatment efficiency and water purification.

On the contrary, white polyaluminum chloride, which exists in the form of powder, is a colorless and transparent liquid after dissolution, giving people a visual sense of fresher. In terms of chemical composition, the alumina content of white polyaluminum is slightly better, usually between 29% and 31%, which provides strong support for the treatment of finer and more demanding water quality. However, its salinity is relatively low, about 50, this feature does not affect its basic function as a water purification agent, but in some specific scenarios, such as the need for stronger flocculation effect of sewage treatment, may need to be used with other agents to achieve the desired effect. Because of its pure appearance and high alumina content, white polyaluminum is more inclined to be applied to the flocculation and sedimentation process in domestic water, circulating water system and various sewage treatment projects with strict water quality requirements to ensure the safety of water quality.

In summary, although yellow polyaluminum chloride and white polyaluminum chloride are both water purifying agents, there are significant differences in composition content, applicable scenarios and price positioning. Users in the choice, should be based on the actual processing needs, cost budget and water quality requirements and other factors to consider, in order to choose a suitable water purification agent products.
