Introduction to Magnetic Concrete Sedimentation Technology

Magnetically enhanced flocculation sedimentation technology involves the simultaneous addition of a material with a specific gravity of4.8-5.1 magnetite enhances the coagulation and flocculation process by combining with pollutants into a single entity, resulting in denser and stronger flocs for faster sedimentation. The sedimentation rate of magnetic flocs can exceed 40 m/h. The magnetite is recycled and reused through high-shear machines and magnetic seed catchers (magnetic separators).

The entire process has a very short downtime, therefore, it is highly efficient for includingMost pollutants within TP have a very low probability of undergoing reverse dissolution. Additionally, the magnetite and flocculants added to the system exhibit excellent adsorption properties against bacteria, viruses, oil, and various fine particles. Consequently, the removal efficiency of these pollutants is superior to traditional processes, with particularly remarkable phosphorus removal effects. Simultaneously, due to its high-speed sedimentation capability, it boasts numerous advantages compared to traditional methods, such as faster speed, higher efficiency, smaller land occupation, and lower investment. Magnetic coagulation sedimentation technology is a revolutionary new technique.

Magnetic coagulation sedimentation technology originated in the United States. Historically, its application in water treatment projects has been limited due to the unresolved issue of magnetic powder recovery. Now, this technical challenge has been successfully addressed, highlighting the technological and economic advantages of the magnetic coagulation sedimentation process, which is gaining wider adoption both domestically and internationally. Currently, in China, the engineering application of this technology in urban wastewater treatment, reclaimed water use, river black and smelly water treatment, high-phosphorus wastewater treatment, paper mill wastewater treatment, and oilfield wastewater treatment has gradually expanded, yielding favorable results.
