Influence of low temperature on liquid aluminum sulfate

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.

Low temperature will affect the effect of aluminum sulfate coagulation

Low temperature will affect the effect of aluminum sulfate coagulation

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.

Evaporative Crystallization of Aluminum Sulfate

Evaporative Crystallization of Aluminum Sulfate

In the production process of aluminum sulfate, the step of evaporative crystallization is indispensable. This is a more important process in the production of finished products. So what equipment is used for evaporative crystallization, and what kind of process is used to complete the fabrication. , let's find out with me.

How to adjust the concentration and dosage of aluminum sulfate

How to adjust the concentration and dosage of aluminum sulfate

Aluminum sulfate is often added to water as a coagulant for sewage treatment, but sometimes its use effect is different. There are many influencing factors, mainly including the quality of water quality itself, stirring factors, and dosage. These will affect the subsequent water purification effect, and different concentrations will also affect the use effect. Let's take a detailed look at how to adjust the concentration and dosage during use.

Iron Removal Process of Aluminum Sulfate

Iron Removal Process of Aluminum Sulfate

At present, the production method of aluminum sulfate mainly uses bauxite for production, but because the iron content in bauxite is very high, the iron content in the finished product will be relatively high, and it may be used in this way. It will affect the use effect, so it is necessary to remove the iron in it. Let's take a look at the process of iron removal by precipitation method. Generally speaking, this method is only suitable for ordinary iron removal. First, a certain content of potassium permanganate solution is added to the hot solution. At this time, a large number of brown precipitates will be formed. Then, after filtering, the filtered filtrate is Concentration and crystallization will result in a product with less iron content. The remaining iron is generally high-priced iron, and the product is yellow in color and looks poor in appearance. In the concentration process, a small amount of aluminum flakes can be added to reduce the unclean iron to ferrous iron, so that the obtained product will be light green with good color, and the color of the product will hardly change within 3 months. The pH value of the solution also affects the iron removal effect. The higher the pH of the solution, the better the iron removal. And the higher the pH, the lower the recovery of aluminum sulfate. In this way, after washing the filter residue, the loss of production can be greatly reduced. If the amount of potassium permanganate is insufficient, the removal effect of iron will also be poor, and even the work of iron removal cannot be carried out. Potassium permanganate first oxidizes ferrous ions to Fe, and manganese is reduced to Mn2t. At this time, there is no precipitation of Fe(OH)3: with the continuous addition of potassium permanganate, Mn2+ will be gradually oxidized to Mn'+ . A small amount of aluminum will be adsorbed together to form a precipitate. The higher the content of generated H20, the higher the iron removal rate. The process of iron removal by precipitation introduced above is only one of the methods for removing iron from aluminum sulfate. We need to choose according to actual needs when using various methods.

How to improve the purity of aluminum sulfate

How to improve the purity of aluminum sulfate

The main use of aluminum sulfate is to use it as a flocculant to purify water in water treatment. There are corresponding regulations on its purity in water treatment. However, in many cases, the purity of products produced by manufacturers may not meet the standards for use. If the product does not meet the standard, the effect of water purification may not meet the expected needs, so how to improve the purity of the product is a very important issue. Let's take a look with the editor. 1. A clean production environment and a standardized production process are conducive to improving the purity of the finished product, which can help the product meet the requirements for use. 2. Do not use ore acid or other by-product sulfuric acid for the sulfuric acid that needs to be used in the production of raw materials, which has a great impact on the purity of aluminum sulfate. 3. It is necessary to ensure that no impurities are mixed in the product during transportation, production and processing. Especially avoid using iron equipment in production and transportation, because iron equipment will produce iron filings and other impurities under acid corrosion, which will also affect the purity of the products produced later. It is recommended to use stainless steel or other anti-corrosion equipment as much as possible. 4. Be sure to choose and use raw materials, which is very important to improve the purity of the product. Generally, it is recommended that manufacturers use aluminum hydroxide as the raw material and use the sintering production process to ensure its purity and whiteness. The four methods described above are all methods of improving the purity of aluminum sulfate. We can choose one or more of them to use during production, so that the produced products can meet the standards for use and achieve the expected results. Effect
