Magnetic coagulation water machinery for industrial wastewater treatment

Magnetic flocculation Introduction：

The magnetic flocculation equipment is suitable for the treatment of most of the sewage and wastewater with high content of suspended solids and colloidal substances. It uses the high-strength magnetic energy product of rare-earth permanent magnetic materials to achieve high magnetic field strength and high magnetic field gradient through the combination of rare earth disks.

Under the action of the magnetic field force, the magnetic flocs formed can overcome fluid resistance and gravity etc mechanical external forces, and generate rapid directional movement, and adhered on the surface of the rare earth disk, thereby adsorbing and separating the pollutants in the wastewater, and then magnetic isolation and slag unloading device unload the adsorbate and dig it into the spiral groove,outputs it through the slag conveying device to realize continuous purification and recycling of wastewater.

Brief description of process flow:

1) The wastewater enters the coagulation reactor and mixes evenly with a certain concentration of magnetic powder. Under the action of the coagulant and coagulant, the suspended solids and colloidal pollutants in the wastewater form magnetic flocs;

2) After the coagulation reaction, the effluent flows into the magnetic separation equipment. Under the high magnetic field strength, the magnetic flocs are absorbed by the disk and pulled out of the water to realize the separation of the magnetic flocs from the water.The effluent directly discharged;

3) The magnetic flocs separated from the magnetic disk are processed by the magnetic powder recovery system to realize the separation of magnetic substances and non-magnetic sludge. The separated magnetic powder continues to be recycled and the sludge enters the sludge disposal system;

4) The process of wastewater flowing into the coagulation reactor till the purification treatment of the magnetic separation equipment, the total residence time is about 3-5 minutes that the sewage can be quickly clarified.

The magnetic powder recovery rate is over 99%. The technical and economic advantages of the magnetic coagulation sedimentation process have been fully reflected.The technology has been more and more widely used worldly.
