Magnetic powder recycling can effectively reduce costs, because a large amount of magnetic powder is required to work in the process of sewage treatment, so the consumption of magnetic powder will be very large, which will increase the cost, but it will be effective after recycling. The use of magnetic powder is reduced, thereby reducing the cost.
The purity and recovery rate of the magnetic powder after being recycled by appropriate treatment methods are also very high, so that the water purification effect of reuse is also very good, and at the same time, the waste of magnetic powder is not caused, and the purpose of saving resources is achieved.
For the sewage treatment plant, it saves a large part of the investment capital, so that the sewage treatment funds are not tight, and the operation can be carried out normally, thereby achieving a win-win situation.
