In tap water, phosphorus is the limiting factor for microbial growth. When a relatively high concentration of organic matter to the water, the water soluble orthophosphate concentration below 10μg / L, P limiting the growth of bacteria in the water will be shown. Most of our water by organic pollution, effluent water can not reach many biological stability requirements. In this case the price of activated alumina, phosphorus as a control factor, is more appropriate than assimilable organic carbon (AOC). Water phosphorus removal methods include biological, physical and chemical alive, wastewater biological phosphorus removal methods commonly used in conventional water treatment process, the removal of phosphorus mainly by coagulation sedimentation and filtration, that use of the chemical and physical methods, coagulation In addition to be able to support a portion of phosphorus, another part of the filtration process to remove dependence. Therefore, the study reinforced filtered to remove trace amounts of phosphorus method is an important way to ensure that the water biological stability. Activated alumina adsorption function as a strong material, if used as filter activated alumina, respond filtered trace phosphorus removal performance test study in depth. In addition to the results of activated alumina filtration pilot study showed traces of phosphorus: activated alumina, mainly through the removal of phosphorus dissolved total phosphorus sorption and physical entrapment and adhesion of the particles on the state of TP, the filtration rate in the same activity When alumina particle size 1-3mm, filtration efficiency index value of the minimum specifications of activated alumina, the particle size range and phosphorus, turbidity optimal performance. Moreover, the smaller the filtration rate, filtration efficiency index is smaller, the better the filtration performance, but too small filtration rate makes water production efficiency. First, activated alumina desiccant This product is a spherical microporous material, has a strong absorption features, and high surface area larger than the compressive stiffness, long life, and can be used repeatedly regeneration method. White, spherical porous material, non-toxic, odorless, not powder, insoluble in water. Widely used in petrochemical, chemical, textile, metallurgical and other industries instrument air drying, pressure swing adsorption air separation unit, adsorption dew point up to -41 degrees, can also be used in the steel, oil cracked gas, ethylene, propylene The depth of the liquid and vapor drying. Physical indicators: the proportion of the compressive strength of the appearance of the heap Na2O specific surface area of ??the wear rate of the white hole spherical 0.7g / ml ≥130N / grain ≥280m2 / g ≥0.38ml / g ≤0.4% ≤0.1% Common Specifications: 3-5㎜ 4- 6 mm 5-8㎜ two, activated alumina adsorbents white or reddish small spherical particles do not dissolve in water and other organic solvents, has a strong adsorbent. Circulation is mainly used for the production of hydrogen peroxide hydrogen peroxide unit regeneration fluid absorption of moisture and impurities. Physical indicators: Al2O3 bulk specific gravity compressive strength than the surface area of ??the aperture area of ??the wear rate of Na2O ≥93% ≥0.63g / ml ≥70N / grain ≥180m2 / g ≥0.38ml / g ≤0.6% ≤0.6% activated alumina prices, Chaohu activity alumina, activated alumina supplied by Saatchi Saatchi Henan water purification materials Limited.
