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, 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 method of waste activated alumina used in conventional water treatment process, the removal of phosphorus mainly by coagulation sedimentation and filtration, that use of the chemical and physical France, coagulation can support in addition to part of phosphorus, another partially dependent filtration process to remove. 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 media, respond to their filtration performance of phosphorus removal of trace pilot 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 activated alumina plant, filtration efficiency index value of the minimum, the particle size range and phosphorus, turbidity optimal performance. Moreover, the smaller the filtration rate, filtration efficiency index is smaller, the better the performance of activated alumina filter, but too small filtration rate makes water production efficiency. [Chinese name] [Applications] high-performance activated alumina activated alumina in monolithic refractories ingredients can bring the following benefits: Increased body density, mobility, strength carrier activated alumina, improve secondary mullite Dan Shengcheng amount, reduce the amount of water and porosity. In addition, activated alumina desiccant can be done, water volume, fast-drying, can be regenerated (400 -500K baking). Activated alumina is alumina having adsorption properties, the catalytic activity of the porous, high dispersion, large specific surface area. It is suitable for drying a variety of gases and liquids, as adsorbents, desiccants, catalysts and carrier oil, fertilizer, chemicals and many other reaction. The product is made of high purity alumina deployment of science, catalysis finishing. High compressive hardness, long life, and can be used repeatedly regeneration method. White, spherical porous material, non-toxic, odorless, not powder, insoluble in water. It Adsorption removal of harmful fluoride, fluoride can be used for drinking water and industrial installations, arsenic removal, sewage bleaching, deodorization.
