Active alumina actually possesses a multitude of functions, which enables its wide application across various industries. In the water treatment sector, it can also be utilized primarily due to its phosphorus removal capabilities. What are some specific details about its phosphorus removal function?
1. When phosphorus is a limiting factor, the concentration of dissolved orthophosphates in the water body is below 10ug/L, phosphorus will exhibit a limiting effect on bacterial growth within the water. The commonly used methods for phosphorus removal are chemical and biological methods. The phosphorus removal by active aluminum oxide adsorption is significant for lake eutrophication, as it has a simple process, no secondary pollution, and the adsorbent can be reused. Currently, research on dynamic phosphorus is mainly focused on the biological methods of phosphorus removal, primarily involving improvements to the equipment and processes of traditional biological phosphorus removal.
2. The adsorption-desorption process on the active alumina catalyst not only achieves the dephosphorization effect but also facilitates the recovery of phosphorus. By regenerating them, it allows for their recycling and simultaneously reduces the cost of phosphorus removal.
3. The phosphorus scavenger exhibits excellent phosphorus adsorption. In dynamic packed bed adsorption tests, the active alumina is still effective in removing phosphorus from water bodies. This provides basic parameters for the phosphorus scavenger. The pH range for adsorptive phosphorus removal is 5-6. After adsorption saturation, it can be recycled by regeneration with NaOH solution.
Therefore, we can remove phosphorus by utilizing active alumina, a chemical product that can be added to phosphorus-containing wastewater to act as a phosphorus remover. This also indicates that it is relatively environmentally friendly; however, strict control must be maintained during its use.
