Chemical Description

  • In daily life, washing clothes, shampooing, flushing toilets, etc., all belong to municipal sewage. Therefore, there are a lot of impurities in the municipal sewage, containing a lot of COD, BOD, ammonia-, nitrogen, phosphorus.
  • Municipal sewage treatment generally has a complete set of processes: Influent→Grate→Biochemical treatment→Sinking tank→Secondary sedimentation tank→Desilting→Disinfection→Waste landfill municipal wastewater treatment process.
  • Polyaluminum chloride is used in the sedimentation section. PAC or polyferric sulfate is subject to flocculation precipitation.
  • The flocculant PAM is added in the desliming step, and the desmearing effect is generally better with polyacrylamide cations.
  • The specific ionization type of the cation is selected in combination with the water concentration and the type of the filter press.
  • Polyaluminum chloride is a water purification material, an inorganic polymer coagulant, and a polymer with a relatively large molecular weight and a relatively high charge of inorganic polymer produced by the bridge action of hydroxyl ions and the polymerization of polyvalent anions. Pharmacy.
  • In form, it can be divided into two kinds: solid and liquid. The solids are divided into brown, beige, golden yellow and white according to different colors, and the liquid can be represented as colorless, transparent, yellowish, light yellow to yellow-brown.
  • The polyaluminum chloride having a content of aluminum oxide between 27 and 30 is mostly khaki-yellow yellow solid powder.
  • These types of polyaluminum chlorides have relatively good water solubility, and in the course of dissolution, physicochemical changes such as electrochemical, agglomeration, adsorption, and precipitation eventually lead to [Al2(OH)3(OH)3] precipitation, thereby achieving the purpose of purification.
  • In the use of polyaluminum chloride, without the need for other additives, floe formation is fast and thick, high activity, rapid precipitation, and a clear effect on high turbidity water purification.
  • The purified water quality is better than aluminum sulfate flocculant, and the water purification cost is 15-30% lower than that.
  • The formation of flocs is quick and the settling speed is fast, which is greater than that of traditional products such as aluminum sulfate.
  • Consumption of water below the alkalinity of various inorganic flocculants, which can not vote or less alkali agent.
  • The source water PH5.0-9.0 can be condensed, small corrosion, good operating conditions.
  • The solubility is better than aluminum sulfate.
  • Less salt increase in treated water is beneficial to ion exchange treatment and high purity water production.
  • The adaptability to the source water temperature is better than inorganic flocculants such as aluminum sulfate.
