Solution of Polyaluminum Chloride Being Insoluble in Water in Use

When using polyaluminum chloride, do you often encounter situations that cannot be fully dissolved in water, and how to solve them? We all know that when using polyaluminum chloride, solution preparation is required first.

Polyaluminum chloride is widely used in various industries, and it can be divided into industrial grade, drinking water grade and other different models. The mineral raw materials for the production of polyaluminum chloride are usually complex in composition. The finer the powder is, the higher the dissolution rate of aluminum oxide is, but it also makes it difficult for insoluble substances to precipitate. If you want to solve the problem of insoluble water in the use of polyaluminum chloride, it mainly depends on the characteristics of the suspension, followed by the quality. Because polyaluminum chloride is a polymer that absorbs sediments, we can see that the sediments that cannot be fully dissolved in water may be adsorbed ions or colloidal groups. Let's take a look at how to solve this problem:

1. Natural sedimentation usually takes a long time and requires a certain site to build a large sedimentation tank.

2. The use of plate and frame filter press can solve the problem of insoluble sediment, but the investment is high and the cost is high. If horizontal spiral centrifuges are used, a large amount of investment will be required.

3. It is also an effective way to control the dosage by adding coagulant aids such as polyacrylamide.

4. The production process of polyaluminum chloride itself is rough, which will also lead to insoluble in water. Because the polyaluminum chloride products contain many impurities, and the content of water insoluble substances exceeds the standard, it will also appear insoluble in water when used. Therefore, when purchasing polyaluminum chloride, products with high quality and good effect should be selected.

The above content is the sharing of solutions when insoluble water occurs in the use of polyaluminum chloride. I hope you can help
