With the pace of development of the world, people turned out for more attention to health issues, how to drink the health and hygiene of drinking water has become a common concern of the world's topic. PAC as the efficacy of water purification products produced is well known that in the past few decades PAC treatment of drinking water for the people made a great contribution. Kasen plant more than thirty years, the main PAC, polymerization * iron, polyacrylamide and basic aluminum chloride and water purifying products. Drinking water level PAC or Kasen most reliable brand thirty years old, old, what are you waiting for? PAC different production methods, divided alkali fusion, acid dissolution method and the two-step method. 1, the alkali fusion reaction with aluminum soda solution of calcium mineral powder obtained sodium aluminate solution, the reaction temperature is 100 ~ ll0 cC, reaction about 4 h. After Walter sodium aluminate solution of carbon dioxide gas, when the solution pH of 6 to 8:00. Forming a large number of aluminum hydroxide gel, then the reaction was stopped. This process is the reaction temperature should not exceed 40cC, otherwise it will form insoluble colloidal aging. Finally, add the right amount of hydrogen generated in alumina * heated and dissolved to give a colorless, transparent, viscous liquid aluminum chloride, aluminum chloride and dried to give a solid. This method is to produce products of low heavy metal content, high purity, but higher production costs. 2, acid digestion method to directly * calcium aluminum powder reacts with the adjustment and get complete basicity PAC liquid products after ripening. The process is simple, low investment, easy operation, low production costs, but the product of insolubles, high heavy metal content, the solid product is usually not high alumina content. Mass fraction of about 28%, poor product appearance, iron content. PAC prepared by acid-soluble iron. 3, this production method is generally two-step production process using a two-step acid dissolution method, at atmospheric pressure and a certain temperature, the first step in adding higher * than the bauxite powder, the alumina as dissolution, the second step is the first step in the supernatant of the reaction of calcium aluminate powder reacts with new entrants. This step both alumina dissolution, but can be adjusted basicity. The first step can usually alumina dissolution of more than 80%, the second step of the aluminum dissolution rate of 50% or less, it is returned to the second stage precipitation slag Usually the first reaction to. With bauxite and aluminum calcium powder as raw material, the use of acid-soluble two-step process, prepared alumina mass fraction of 10.11%. Basicity PAC 85% of the liquid product. Materials Plant in Henan Kasen water treatment products are all up to the national standard-setting water purification materials; and passed the ISO9001 international quality system certification and ISO14001: 2004 Environmental Management System Certification; for many years by the local government, "the contract and trustworthy enterprise . " Mr. Yuan Mengbin was named director in November 2008 as president of the Association of Gongyi City, water purification materials, Chinese Chemical Society in 2009 as vice president of the Professional Committee of treatment. In the same year, Kasen Plant participated in the drafting of the "poly aluminum chloride national standard GB15892-2009" formulation, 袁孟斌 total director to become one of the drafters of the new national standard, which is more than thirty years in China Springs Water Treatment Plant industry full recognition!
