III. Product Features
| Key Advantages | Description |
|---|---|
| High – efficiency High – flow Filtration | Single – unit processing capacity ranges from 10 – 500m³/h, suitable for large – scale continuous water treatment scenarios. |
| Deep Dirt – intercepting Ability | The quartz sand filter layer forms a gradient pore structure, effectively intercepting impurities with a particle size of 5 – 500μm, and the effluent turbidity is <5NTU. |
| Low – consumption Energy – saving Design | Backwash water consumption is only 1 – 3% of the treated water volume, and energy consumption is reduced by 40%, significantly saving operating costs. |
| Long – life Maintenance – free | Quartz sand filter media is wear – resistant and corrosion – resistant, with a service cycle of over 5 years under normal conditions, reducing replacement frequency. |
| Flexible Customization | Supports multi – unit parallel expansion, and filter layer thickness and backwash parameters can be adjusted according to water quality requirements. |
