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 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, activated alumina, filtered to remove trace amounts of phosphorus strengthen research method is an important way to ensure 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, 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 filtration performance, but too small filtration rate makes water production efficiency. Activated alumina desiccant, strong moisture absorption, which can effectively prevent the ocean transit, due to temperature and humidity changes cause condensation inside the container damaged goods - moisture, mildew, rust, oxidation, etc., such as cardboard boxes or directly affect the appearance of stains appear damaged packaging, and even affect the quality of products such as corrosion of metal parts falling off or label. Activated alumina desiccant absorbent Principle: container with desiccant ingredients are calcium chloride, at 25 ℃, relative humidity of 90% under the conditions of adsorption of water vapor up to the maximum capacity of 250% its own weight of activated alumina price, achieve the performance of similar foreign products. Moisture absorption capacity will reach 250% activated alumina balls, each capable of absorbing two kilograms of dry sticks of crystal water, is a common drying agent (such as silica, montmorillonite, mineral desiccant) 5-10 times, under the same environmental conditions. You greatly reduce the cost of activated alumina joint safety and environmental protection: environmental protection products, do not harm the environment, non-toxic activated alumina carrier, natural degradation. Tyvek way adsorption of packages that can effectively lock in the moisture is not anti-infiltration of Tyvek package inside. Fast absorption rate: under the same environmental conditions, activated alumina desiccant absorption rate is common desiccant (such as silica gel, montmorillonite, mineral desiccant) twice. Activated alumina desiccant safety and environmental protection: environmental protection products, do not harm the environment, non-toxic, naturally degraded. Activated alumina desiccant container can be quickly and effectively control the dew point: it strongly absorb moisture from the air, reduce the humidity inside the container, thereby preventing the formation of dew. Even condensation produces dry can quickly absorb them. By preventing condensation from the fundamental solution to the problem of container cargo damage occurs due to damp.
