We have mentioned many times in previous articles that aluminum sulfate can play a coagulation effect in water treatment. If the water temperature is so low, can coagulation still achieve the original effect? Let's find out whether low temperature will affect the coagulation effect.
The concentration added in sewage treatment is generally 10% concentration. When the water temperature is 0 degrees Celsius, its hydrolysis rate is only 2/3-1/2 of that at 10 degrees Celsius. And foreign related tests also show that as the water temperature increases by 10 °C, its reaction rate will be 1-2 times higher.
This is because the lower the temperature of the water, the greater the viscosity will be, which will increase the settling resistance. It is difficult for the suspended particles in the water and the flocs formed after the hydrolysis of aluminum sulfate to settle, which will slow down the speed. On the other hand, when the water temperature is low, the material of the water body will increase, and the shear force of the water flow will increase accordingly. When the water flow is stirred, the formed flocculation will also be impacted, and then become broken, loose, and flocculated. Not easy to settle.
Moreover, when the water temperature is low, the potential of the particles in the water is relatively high, and the repulsive reaction between the particles is relatively large, which will increase the repulsive force and the mutual repulsion is relatively serious; and when the water temperature is low, the Brownian formed by the aluminum hydroxide particles in the water is relatively large. When the kinetic energy of motion is reduced, the material hysteresis of water will also be enhanced; in addition, when the water temperature is low, a layer of water film is easily adhered around the particles with adsorption effect, which will also hinder the progress of coagulation.
Through the above introduction, we have learned that low temperature will indeed affect the coagulation effect of aluminum sulfate. The water temperature is within a certain range, and the higher the temperature, the better the reaction effect.

The production process of aluminum sulfate

Aluminum sulfate has a very good application in papermaking, water purification and other aspects. In the production, many used bauxite for production, but it is easy to cause the consumption of raw materials and the quality of the produced products. It will also be affected to a certain extent. Among various methods, only using kaolin as raw material for production is cost-effective, and the production process is relatively stable, and the quality of the produced products is relatively good.

Aluminium sulfate improves soil salinization

There is a lot of land in my country that cannot be planted with crops, because the alkalization and salinization of these soils are serious, and crops cannot grow. Aluminum sulfate can be used to improve the salinization of the soil. The improvement effect of soda saline-alkali soil is very significant. The following Let's learn more about it.

Inspection process of aluminum sulfate

Aluminum sulfate needs to be inspected when it leaves the factory. Only qualified products can be used in the factory. What is the inspection process of the product? Let's learn about it next, but this process is only used for the inspection of the product when it leaves the factory. Other situations need to be checked against other standards.

Chemical Properties of Aluminum Sulfate

Aluminum sulfate is widely used in industry. It can be used as a sizing agent in papermaking, as a flocculant and sewage purifier in water treatment, and many other uses, which are related to its own chemical properties. It is related. Its chemical properties make it widely used in many fields. The following editor will introduce its chemical properties.

Influence of low temperature on liquid aluminum sulfate

With the arrival of winter, the temperature is getting lower and lower, and it has begun to be lower than 10 degrees Celsius, so the editor thought, in such cold weather, will the use of aluminum sulfate also have an impact, and in this I think the impact of low temperature on liquid products should be relatively large, let's take a look.
