Technical advantages of magnetic separation wastewater treatment equipment

The magnetic separation sewage treatment equipment is improved based on the current loading sedimentation tank. The equipment adopts magnetic separation technology, which highly integrates various solid-liquid separation technologies such as chemical coagulation, mechanical stirring, loading sedimentation, inclined tube separation, etc. into a sewage treatment equipment.

The difference between magnetic separation sewage treatment equipment and traditional sewage treatment equipment depends on the shorter solution time, and the entire operation process can be completed in 10-15 minutes. The effluent quality SS can reach below 5mg/L, TP can reach below 0.3mg/L, and it also has a good removal effect on COD, BOD, ammonia nitrogen, fine particles, etc. in sewage. At the same time, it has strong shock load resistance and can still operate stably under high concentration and high pollution conditions.

Magnetic separation technology is an innovation of water precipitation technology, which combines the characteristics of various precipitation technologies. This is mainly reflected in high sedimentation efficiency, stable and excellent effluent quality, small footprint, strong impact resistance, flexible and reliable operation, and energy-saving operation.

1. High sedimentation efficiency

The magnetic separation tank creates favorable conditions for the formation of rapidly precipitating alum, supplemented by the characteristics of external medium, inclined tube separation, and perfect hydraulic design, enabling the system to achieve an upward flow rate of up to 20-40m/h.

2. Stable water output

Good coagulation and flocculation conditions enhance the capture and aggregation of pollutants. Its excellent suspended solids removal ability can rival conventional filtration, and the SS of general wastewater deep treatment can be stably less than 10mg/L, with total phosphorus less than 0.1mg/L

3. Small footprint

The ultra-high upward flow rate, extremely short reaction time requirements, and compact structural design make magnetic separation wastewater treatment equipment one of the current compact wastewater treatment equipment. It occupies more than 40% less land than the currently commonly used high-efficiency sedimentation tanks.

4. Strong impact resistance

Controlling the sludge concentration (around 4-8g/l) of the flocculation reaction tank * through sludge reflux is a normal operating condition of the magnetic separation tank. Compared with the sludge concentration in the raw water, the concentration of circulating sludge is much higher. Changes in the raw water concentration will not affect this operating condition, so it will not damage the formation of alum and will not affect the normal operation of the system.

5. Save operating chemicals

The stirring reaction design of the magnetic separation wastewater treatment equipment improves the reaction efficiency of the reagents, and the setting of sludge reflux can further recycle and utilize incompletely reacted reagents, greatly reducing the amount of reagents required for the system to achieve the same reaction efficiency. Generally, it can save 10-20% of the amount of reagents used, thereby significantly saving operating costs.
