China Factory Suppliers ABS Frame 4V-Type Activated Carbon Filter with Multi-layer Super Fine Carbon Media
We have 3 types of Carbon Activated Media to meet your needs:
Activated carbon is the core of the filter, and its type and quality directly determine the filtration performance.
- 🛢️ Shell: Usually a vertical tank made of carbon steel (with internal anti-corrosion lining) or stainless steel.
- 💧 Upper Water/Air Distribution System: Ensures even distribution of fluid or gas across the top cross-section of the filter.
- 🔺 Activated Carbon Bed: The core component. The activated carbon (often granular) is supported by V-shaped screens, wedge-wire filter tubes, or perforated plates, forming a "V"-shaped cross-section — narrow at the top and wide at the bottom.
- ⬇️ Lower Water/Air Collection System: Collects the medium that has passed through the filter bed.
- 🔧 Accessories: Sight glass, manhole, sampling port, pressure gauge, etc.
The efficiency depends on the carbon content, normally ranging from 2.0 to 4.0, and can be selected based on specific requirements. The rational selection of filter efficiency and face velocity contributes to comprehensive economic benefits.

1. Down Flow Operation
Normal filtration direction is top-to-bottom.

2. Regular Back Washing
Aims to remove trapped suspended solids and loosen the carbon bed to prevent compaction. Backwash direction is bottom-to-top. Intensity and duration must be controlled to avoid activated carbon loss.
- Pressure Differential: Backwash is required when the inlet-outlet pressure drop increases to a set value (typically 0.05–0.1 MPa).
- Effluent Quality: Indicators like residual chlorine, COD, TOC. Exceeding limits indicates carbon adsorption saturation.
- Activated Carbon Replacement: When adsorption capacity is saturated and cannot be restored by back washing or regeneration, the media must be completely replaced. Replacement cycles for V-type filters are typically longer than for conventional filters.
The V-Type Activated Carbon Filter, through its unique V-shaped bed design, effectively addresses the pain points of traditional filters: uneven flow distribution, channeling, high pressure drop, and low carbon utilization. It is a highly efficient, energy-saving, and long-lasting activated carbon adsorption device, particularly suitable for medium to large-scale water treatment and air purification systems requiring high treatment effectiveness and operational stability.
When selecting a unit, the filter size, activated carbon type, and specifications must be designed based on the characteristics of the medium being treated (flow rate, pollutant concentration, pH, temperature, etc.), treatment requirements, and available system space.
