How about cationic polyacrylamide flocculant for dewatering of brewery wastewater?

How about cationic polyacrylamide flocculant for dewatering of brewery wastewater?

2019/07/25

The wastewater produced by the brewery will have a lot of organic matter, because of his process more so it produces a variety of wastewater, the output of wastewater with washing water, wheat trough water, soaking water and so on many processes will produce wastewater, if not directly deal with environmental pollution. Now the beer manufacturers basically use cationic polyacrylamide, the sludge of the brewery has efficient flocculation, after the belt filter press mud cake water content is low, and the amount of polyacrylamide used is also less. The pressed mud cake contains high organic matter, which can be accumulated with other organic matter to ferment into compound organic fertilizer.

Polymeric ferric sulfate and ferrous sulfate are actually such a relationship

Polymeric ferric sulfate and ferrous sulfate are actually such a relationship

2019/07/25

Many people do not understand the polyferric sulfate and ferrous sulfate mixed, they are not a product, but are all iron salt coagulants, performance and effect on a lot of the same place. Ferrous sulfate hydrolysis attack 2 valence iron ions, polymeric ferric sulfate hydrolysis attack 3 valence iron ions, ferrous sulfate has oxidation recovery properties, and polymeric ferric sulfate does not have. In terms of use, polyferric sulfate has relatively strong stability, is more convenient to store than ferrous sulfate, forms larger alum flowers, more compact flocs, and has less dosage than ferrous sulfate. However, polyferric sulfate is produced with ferrous sulfate as raw material, and iron ore and the like as raw material, that is to say, sulfuric acid

The role of white, yellow and brown polyaluminium chloride is introduced in detail.

The role of white, yellow and brown polyaluminium chloride is introduced in detail.

2019/06/19

Polyaluminum chloride from the appearance of the product can be divided into white, yellow, brown three, from the alumina content can be divided into 28%, 29%, 30% three, then the different appearance of polyaluminum chloride from the role and product performance What are the different. White polyaluminum chloride is also known as high-purity iron-free white polyaluminum chloride or food-grade polyaluminum chloride. Compared with other polyaluminum chloride products, white polyaluminum chloride is the highest quality and best performance product. Its main production raw materials are composed of high-quality aluminum hydroxide powder and hydrochloric acid, and the production process used is the best spray drying process at present. White polyaluminium chloride can be used as paper sizing agent, sugar with decolorization clarifier, as well as medicine, cosmetics and drinking water purification and precision casting and other fields. The raw materials for the production of yellow polyaluminum chloride are composed of calcium aluminate powder, hydrochloric acid, bauxite, etc., which are mainly used in industrial wastewater treatment and drinking water treatment. The raw materials used for drinking water treatment are aluminum hydroxide powder, hydrochloric acid and a small amount of calcium aluminate powder. The production process uses a plate and frame filter press process or a spray drying process. In terms of drinking water treatment, China has strict regulations on the content of heavy metals in drinking water, so whether it is from raw materials or production process, yellow polyaluminum chloride is better than brown polyaluminum chloride. Yellow polyaluminium chloride production is usually manufactured by drum drying or spray tower drying, the appearance of flake or powder two solid forms. The raw material for the production of brown polyaluminium chloride is composed of calcium aluminate powder, hydrochloric acid, bauxite and iron powder. The production process adopts the drum drying method, which is mainly used in the sewage treatment industry. The brown color is caused by the addition of iron powder in the raw materials. The more iron powder is added, the darker the color will become. When the amount of iron powder added exceeds a certain amount, it is also known as polymeric aluminum ferric chloride, which plays a more excellent role in sewage treatment.

Effect of Polyaluminium Chloride in Mineral Water

Effect of Polyaluminium Chloride in Mineral Water

2019/06/19

Generally speaking, the regular mineral water manufacturers are from more than 1000 meters of groundwater as raw materials. All of this water has been tested by professional water quality testers and the water quality is considered good. On the one hand, the reason for choosing mineral water is that the water source is deep enough to greatly reduce the possibility of water source pollution; on the other hand, the value of mineral water is that it contains a lot of beneficial minerals. In order to further ensure the safety of mineral water, it is often necessary to treat mineral water to remove harmful internal substances. And in many cases, mineral water is not directly used for drinking, but also drugs or other raw materials in the production process, also need to be processed. Then the problem arises. In order to ensure the safety of the water, it is also necessary to ensure that the original minerals are not clear in the water. Otherwise, the value of selecting underground mineral water deep in the surface will not be reflected. Therefore, the required water purification material can not only play the role of water purification, but also will not damage or remove the minerals in the mineral water itself. Polyaluminum chloride can fully meet this requirement. As we said just now, the mineral water is located more than 1,000 meters underground and is basically not polluted by industrial harmful substances or heavy metal elements. The only thing to do is to remove impurities from the water and retain the minerals in it. And the role of polymeric aluminum chloride is such. It has stable quality and high purity. It will not change the water quality, but it can make the impurities in the water condense and precipitate well. Solve the problem of mineral water purification.

Can polyaluminium chloride be used to treat and purify seafood processing wastewater to reach the discharge standard?

Can polyaluminium chloride be used to treat and purify seafood processing wastewater to reach the discharge standard?

2019/07/25

With the improvement of people's quality of life, cities far away from the coastline can get sufficient seafood products. There are countless seafood processing enterprises behind this. As more and more processing plants are springing up, our environment is also facing the situation of being destroyed. Seafood processing will discharge a large amount of wastewater. The organic matter concentration in these wastewater is high, the color is high, and there are a large number of high-quality and free proteins, if it is discharged without purification treatment, it will directly seriously affect the ecological environment of the water area. In order to treat this kind of wastewater, we usually use economical methods. Polymeric aluminum chloride coagulation method is now more common in sewage treatment
