Aluminum sulfate for water treatment

product alias Formula AL2(So4)3-XH2O

CAS: 17927-65-0


Solid indicators of aluminum sulfate that are used in the implementation of national standards HG t2225-2001, the main manufacturing and operation: normal aluminum sulfate, aluminum and liquid aluminum sulfate products, such as aluminum oxide >=15.8 iron <=0.005 water-insoluble matter <=0.02 PH >=3.0 specific gravity 1.69 performance aluminum sulfate with no white crystals of iron The ratio is 1.69, water-soluble but not in alcohol. the solution in water turns acidic. The dehydration temperature is 8605 degrees. increasing to 250°C to remove clean water. anhydrous aluminum sulfate heated until 300 degrees started to decompose. When temperatures reach 860 degrees Celsius the aluminum sulfate decomposes into the r-AL2O3 form, and the anhydrous substance becomes a white crystal that has Pearl Luster. It is used primarily for papermaking and sizing agents and for post-coating treatment for titanium dioxide production. It can also be used in papermaking as a sizing agent, and also in flocculants of industrial water, and wastewater treatment, resulting in catalyst carriers artificial gem as well as aluminum salts. It can also be used to clarify oil and as an deodorizer and oil decolorizer. Concrete waterproofing agent and rain-proof cloth are the raw materials. Specifications of the product for powder 20 mesh 40 mesh and 60 mesh. 1 sheet (5-20) 2 mm2 Powder =5 mm <=(1-3) millimeters



Aluminium aluminium sulphate for water treatment ,it is utilized by the industry of paper to act as a precipitating agent in wax and rosin emulsions as well as a flocculant for the drinking water industry, in industrial water, and industrial wastewater treatment. If aluminum sulfate has been added to this water, colloidal aluminum hydroxide is formed. It can be used to adsorb and then precipitate colloids, bacteria as well as other suspensions. They is employed in the treatment of drinking water to regulate the taste and color that the drinking water has.



Aluminum sulfate can be an aqueous coagulant found in nature and is employed in the processing of food items. The properties of aluminum sulfate are an uncolored or white crystallized powder that has the ability to hygroscopically. It has a high acidity and reacts with alkali to create a similar salts and water. The aqueous solution of aluminum sulfate is acidic, and it can precipitate the aluminium hydroxide. Aluminum sulfate is a powerful co-coagulant that is used in papermaking, water treatment or tanning industry.


Applications: Aluminium sulfate is the most important ingredient in the production of various aluminium compounds, including Aluminium hydroxide, aluminum nitrate as well as aluminium chloride. . Aluminum sulfate is a key coagulant, widely employed in papermaking, water treatment and tanning. The utility model can aggregate organic matter that is suspended in water into massive agglomerates making it easier to get rid of. Aluminum sulfate may also be utilized as a catalyst and fixative for chemical reactions, and separation processes play a significant function. Aluminum sulfate may also be employed in the food and pharmaceutical industries as a pharmaceutical or food additive.


The sulfate of aluminum has a broad array of uses. As we can see that in the extinguishing of foam agent aluminum sulfate is the primary component. It is made up of baking soda and aluminum sulfate and the composition of the foaming agent. Aluminum sulfate, also known as water purification agent, which plays the same function as alum in the process of removing sewage plays a crucial role. Additionally, if slugs have been discovered in the room during the rainy season, spray an aluminum powder or sulfate solution on the area they are active, to destroy them. The results are excellent.



Aluminium sulphate in water treatment

The procedure for using industrial aluminium sulfurate is to add normal tap water at a temperature of the dissolving pool, then start the agitator, and then add the aluminium sulphate. The proportion of aluminium sulphate to tap water will be 1:5-2:5(weight ratio) (weight ratio) and then stir until the green liquid is even, completely dissolving, and diluted with water until it reaches the desired level. Note that the PH of water ranges between 5 to 8. Due to the diverse characteristics of the pure water, it's essential to adjust the treatment on-site or create a beaker tests based on the characteristics of treated water to determine the most appropriate conditions for use and dosage for the most effective treatment results. For flocculation the amount of aluminium sulfate ranges from 5 to 50 mg/L It could be increased to 90-110 mg/L to remove phosphorus. The solution pool used for dissolving aluminum sulfate should be constructed out of PVC plastic or a corrosion-resistant material.
