Introduction to Magnetic Concrete Technology:
Magnetic coagulation sedimentation is a new type of water treatment device. It works by introducing magnetic particles (i.e., magnetic powder) into the water purification process of an efficient flocculation sedimentation pool. Through actions such as flocculation, attraction and adsorption, charge adsorption, bridging, and net trapping, it effectively combines algae, fine suspended particles, colloids, bacteria, and other insoluble pollutants in the water with the magnetic particles (with a specific gravity of 5.2) to form larger and denser magnetic flocs, enhancing the flocculation effect. It can capture and coagulate even smaller particle-sized pollutants, with rapid sedimentation of the flocs and excellent water purification results, resulting in clear and transparent effluent. The sludge from the sedimentation pool is pumped to a magnetic powder sludge separation system for the recovery of magnetic powder for recycling. The separated sludge is then discharged into a sludge pond for dewatering treatment.
Advantages of Magnetic Concrete Technology:
Highly efficient deep purification, superior performance (higher processing capacity than any existing purification technology), outperforming high-efficiency inclined tube sedimentation tanks/flocculation tanks/filtration tanks/sieve plates, and can effectively remove non-soluble pollutants such as SS, algae, oils, bacteria, colloids, and their associated turbidity, COD, color, and odor (SS<3mg/L, turbidity<1.0NTU) simultaneously. The use of coagulants like Fe or Al can also achieve deep phosphorus removal (TP<0.05mg/L); combined with pre-oxidation, it can deeply remove iron, manganese, and arsenic; the addition of Ca(OH)2 and organic sulfur for pre-chemical precipitation can efficiently remove various heavy metal ions such as Cu, Cd, Hg, Pb, Cr, Zn, Mn, and Ni; the addition of Ca(OH)2 for pre-chemical precipitation can soften water quality (reduce hardness/alkalinity).
Short system dwell time (less than 15-20 minutes), saves space, takes up only 1/5 of the area of a slotted tube sedimentation tank or dissolved air flotation (DAF) tank, and 1/20 of a traditional sedimentation tank; low construction cost.
Low power consumption, low operating costs.
High recovery rate of magnetic powder (99.9%), with a lower loss rate of 70% compared to other magnetic絮凝 magnetic separation systems.
Water tolerance and resistance to水质 fluctuations, stable effluent specifications. Quick start-up time (＜10 minutes).
In drinking water treatment, turbidity, color, total organic carbon (TOC), algae, particle count, bacteria and pathogens, cryptosporidium, iron oxide, manganese, and arsenic removal rates exceed 90%.
In wastewater treatment, the removal rates for total suspended solids (TSS), colloidal matter, total phosphorus, heavy metals, and E. coli reach 90% to 99%. Removal rates for BOD and COD are 60% to 80%.
