Product Introduction:

Aluminum sulfate, white orthorhombic crystalline powder. In the paper industry, it is used as a precipitating agent for rosin gum, wax emulsion and other rubber materials, as a coagulant for water treatment, as an internal retention agent for foam fire extinguishers, and as a raw material for the production of alum and aluminum bags., petroleum bleaching, deodorant and some pharmaceutical raw materials, etc. Also can produce artificial gemstones and ammonium alum.

The main use of aluminum sulfate, accounting for about 50% of the total production, is for papermaking, and the second use is as a coagulant in the treatment of drinking water, industrial water and industrial wastewater, accounting for about 40% of the total production. Total production of aluminum sulfate. The addition of aluminum sulfate to this type of water can produce colloidal aluminum hydroxide flakes that can adsorb and precipitate bacteria, colloids and other suspended solids, which can be used in drinking water treatment to control the color and taste of water.

Product function:

  1. Aluminum sulfate is a widely used industrial reagent and is often confused with alum. Alum is a double salt of aluminum sulfate and potassium sulfate, and aluminum sulfate is a single salt. Double salts, also called gravimetric salts, consist of two or more single salts that are ionized into a single salt ion in solution.
  2. Aluminum sulfate is commonly used as a flocculant for the purification of drinking water and sewage treatment equipment, and is also used in the paper industry.
  3. Aluminum sulfate is also a very effective mollusk insecticide that can kill Spanish slugs.
  4. When dissolved in large amounts of neutral or slightly alkaline water, it produces colloidal precipitation of aluminum hydroxide Al(OH)3. When printing and dyeing fabrics, aluminum hydroxide colloids make it easier for the dye to adhere to the plant fibers.
  5. Aluminum sulfate is also used to adjust the pH of the soil because it hydrolyzes to produce aluminum hydroxide and a small amount of a dilute sulfuric acid solution.
  6. It is used as a coagulant in sewage treatment and has excellent decolorization properties. Together with ferrous sulfate, it has the functions of removing heavy metal ions, degreasing, dephosphorization, sterilization, especially decolorization and COD removal of printing and dyeing wastewater. .
  7. It is used as a precipitant and can remove sulfides and phosphates by forming precipitates with sulfide, ferrous sulfate heptahydrate, and phosphate. Used as a deodorizing and decolorizing agent in the petroleum industry. It is used as an astringent in the pharmaceutical industry and is also used as a waterproofing agent.
  8. Aluminum sulfate is easily soluble in water, and aluminum sulfate aqueous solution is weakly acidic, so it is widely used as a water purification agent for drinking water and industrial water. It is suitable for wastewater treatment with low alkalinity.

Usage introduction:

  1. Pour room temperature tap water into the dissolution tank, turn on the stirrer, add aluminum sulfate to tap water in a ratio of 1:5 to 2:5 (weight ratio), and mix until uniform. When the pale green liquid is complete, dissolve it, add water, and dilute it to the required concentration. Note: The PH value of water is 5-8.
  2. Due to the different characteristics of the raw water, in order to achieve the most ideal treatment effect, on-site debugging or beaker testing should be carried out according to the characteristics of the treated water quality to select the best use conditions and dosage. . The dosage of aluminum sulfate in flocculation treatment is usually 5-50 mg/L, and the dosage can be increased to 90-110 mg/L for phosphorus removal.
  3. The dissolution pool for dissolving aluminum sulfate must be made of PVC plastic or corrosion-resistant material.

Note: This method is for reference only, and the actual usage shall prevail
