Introduction to Magnetic Loading Process

Magnetic loading technology is a traditional flocculation process that involves adding magnetic powder to form high-density flocs and increasing their specific gravity, in order to enhance the flocculation effect and achieve efficient decontamination and rapid settling. The electric ion polarity and metallic properties of magnetic powder, as the core of flocs, greatly enhance the coagulation and binding ability of suspended pollutants in water, reduce the amount of flocculant used, and achieve better results in removing suspended solids, especially phosphorus, bacteria, viruses, oil, heavy metals, etc. than traditional processes. Due to the high density of magnetic powder reaching 5.0, which is approximately twice that of sand, the density of flocs mixed with magnetic powder increases, causing them to settle rapidly at a speed of over 20 meters per hour. The entire water treatment process can be completed in about 10 minutes from inlet to outlet. The magnetic powder in the sludge can be separated and recovered through a magnetic drum based on its own characteristics, and then recycled in the system.

Characteristics of Magnetic Loading Technology Process

Compared with other processes, magnetic separation technology has the following advantages:

(1) The magnetic loading process can be applied to primary, tertiary, reclaimed water, industrial wastewater, and drinking water in urban areas.

(2) The treatment effect is good, and the effluent quality is comparable to that of ultrafiltration membrane effluent. The magnetic loading process can effectively remove particulate pollutants, microbial pollutants, and some pollutants that have been dissolved in water, such as COD, BOD, suspended solids, total phosphorus, chromaticity, turbidity, etc., especially for phosphorus, it has a strong removal effect. It can also be combined with biological processes to efficiently and economically remove nitrogen.

(3) Strong shock load resistance and unique shock resistance to water quality impact. When there is a malfunction in the current process or other harmful metal ions enter the sewage treatment system, the sewage can directly enter the magnetic separation system, and the system can still maintain a high removal efficiency, greatly removing pollutants from the water.

(4) The land occupation is extremely small, with a BFMS system of 10000 tons per day occupying approximately 300m2.

(5) Low investment, with significant advantages over membrane treatment.

(6) Low operating costs, long service life of equipment, and no need to replace parts, resulting in high secondary investment, in addition to normal maintenance.

(7) Easy operation management, quick startup, and simple operation management.
