What is the difference between ferrous sulfate and polyaluminium chloride?

2025-03-18
Ferrous Sulfate Polymer and Polyaluminium Chloride are two common water treatment chemicals, they have their own advantages and scope of application in the water treatment process, Ferrous Sulfate Polymer is a common water treatment chemicals, it can be used for coagulation and precipitation of suspended solids in sewage. It is mainly composed of iron sulfate and polymer. Ferrous sulfate polymers work by clumping suspended materials together to form larger particles, making them easier to settle. Polymeric ferric sulfate also removes heavy metal ions and phosphates from water, which makes it an ideal wastewater treatment agent. So what is the difference between polymeric ferric sulfate and polyaluminium chloride? Unlike polymeric ferric sulfate, polyaluminium chloride is primarily used to treat dissolved ions in water, such as ammonia and nitrite in wastewater. The chemical components of polyaluminium chloride are aluminium chloride and polymers. It works by removing organic and inorganic substances from water by adsorbing pollutants. Polyaluminium chloride also regulates the pH of water, which makes it more suitable for certain applications. Although both polymeric ferric sulfate and polyaluminium chloride are agents used for water treatment, there are significant differences between them. Firstly, they have different chemical compositions, with ferrous sulphate consisting mainly of iron sulphate and a polymer, while polyaluminium chloride consists of aluminium chloride and a polymer. Secondly, their applications are also different. Ferrous sulfate is mainly used to remove suspended matter and heavy metal ions from water, while polyaluminium chloride is mainly used to remove dissolved ions and organic matter from water. The treatment effects of ferrous sulfate polymerisation and polyaluminium chloride are also different. Although they can both remove pollutants from water, they do not have the same removal effect for different types of pollutants. For example, polyaluminium chloride has a good removal effect on ammonia nitrogen and nitrite in water, but a relatively poor removal effect on heavy metal ions in water. Polymerisation of iron sulfate for the removal of suspended solids and heavy metal ions in the water is better, but for the removal of dissolved ions and organic matter in the water is relatively weak. The use of ferrous sulfate and polyaluminium chloride is also different. Ferrous sulfate is usually used together with alkaline substances to adjust the pH value of the water to enhance its coagulation effect. Polyaluminium chloride, on the other hand, needs to be used with acidic substances to achieve the same effect. Therefore, when using these two types of chemicals, it is necessary to choose the appropriate chemicals and their use according to the pH value of the water and the type of pollutant. The prices of polymeric ferric sulfate and polyaluminium chloride are also different. Because the preparation process of polyaluminium chloride is more mature, so its price is relatively low. The preparation process of polymeric ferric sulfate is more complicated, so its price is relatively high. In short, although polymeric ferric sulfate and polyaluminium chloride are common water treatment chemicals, but there is a big difference between them. Their chemical composition, application scope, treatment effect, use and price are different. Therefore, when choosing to use these two agents, you need to choose according to the actual situation of the water and the type of pollutants that need to be removed. 不同颜色的PAC The main products of flocculant manufacturer Xinhuan Water Treatment are: White polyaluminium chloride (food grade), drinking grade polyaluminium chloride, industrial grade polyaluminium chloride, anionic polyacrylamide, cationic polyacrylamide, nonionic polyacrylamide, petroleum recycling polyacrylamide, oil recovery polyacrylamide, polyacrylamide, polymer flocculant polymer flocculation coagulant, polymeric ferrous sulphate, polymerized iron and aluminium chloride, and other water treatment chemicals.
