High-Efficiency Magnetic Sedimentation Equipment

1. Principle of the Device & Application Scenarios

The High-Efficiency Magnetic Sedimentation equipment has been widely recognized and applied in the environmental protection field. By adding magnetic powder into the reaction tank, since the magnetic powder generally has a relatively high density, the flocs wrapped with magnetic powder also have a large specific gravity. This helps to accelerate the sedimentation speed of flocs, shorten the sedimentation time, and achieve the purpose of efficient sedimentation. The magnetic powder is recycled through a magnetic recovery device.

The "High-Efficiency Magnetic Sedimentation Equipment" revolutionizes sedimentation speed. Typical applications include:

• Drinking water treatment, when used for the renovation of conventional sedimentation tanks, it can enhance the treatment capacity by 5 to 10 times without increasing the occupied area.

• Municipal wastewater treatment (post-biological treatment) for phosphorus removal and suspended solids, to ensure compliance with the first-class A discharge standard or even stricter requirements;

• Treatment of mildly polluted water bodies to remove organic matter, phosphorus, and suspended solids;

• Industrial wastewater treatment, replacing traditional coagulation and sedimentation, It saves land occupation and can also be combined with "enhanced Fenton" technology to achieve the purpose of advanced treatment.

 2. System Composition 

The entire treatment system equipment includes a magnetic flocculation reaction system, a high-efficiency magnetic Sedimentation  system, a magnetic medium circulation system, a fully automatic dosing system, and an automatic control system.

3. Equipment Advantages 

Under the condition of optimization and improvement based on numerous operation cases, the "High-Efficiency Magnetic Sedimentation" technology of Kaifa Intelligent Equipment has the following unique values, distinguishing it from similar products:

• It features fast sedimentation speed, high surface load, and small floor space, which is only 5-15% of that occupied by conventional coagulation and sedimentation equipment.

• The equipment achieves excellent effluent quality. It has a better removal effect on pollutants present in the form of colloids and suspended solids, and can realize advanced phosphorus removal with TP (total phosphorus) less than 0.03mg/L.

• Due to its small footprint, the equipment can achieve skid-mounted, mobile or vehicle-mounted mobile services through integrated and intensive design.

• The equipment has a short delivery cycle. The reaction and sedimentation system adopts an integrated horizontal flow design, with the tank body and sludge scraper pre-assembled in the workshop. This results in fewer on-site connection points for the main system equipment, enabling quick on-site installation. Generally, our delivery cycle can be shortened to 4-6 weeks (from factory shipment).

• The equipment is simpler. Instead of the traditional water pump reflux method, the sludge reflux and magnetic powder reflux adopt a unique pneumatic conveying method, which avoids problems such as high performance requirements for water pumps (especially for wear resistance) and easy pump clogging caused by special sewage.

• It features a high level of automation. Each piece of Kafa’s equipment can achieve unmanned operation and full-process (including remote) operation monitoring, enabling truly worry-free operation.
