    🔬 Filter Media Materials

    We have 3 types of Carbon Activated Media to meet your needs:

    Type A
    VOCs and Ozone, etc.
    Type B
    Acidic Gases (SO₂, NO₂, H₂S, HCL, HF, etc.)
    Type C
    Alkaline Gases (NH₃, Amines, etc.)

    Activated carbon is the core of the filter, and its type and quality directly determine the filtration performance.

    ⚙️ Main Structure & Working Principle
    • 🛢️ 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 that is 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 of V-Type Activated Carbon Filter

    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.

    🛠️ Key Operation & Maintenance Points
    • 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.
    📈 Monitoring Indicators
    • 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 backwashing or regeneration, the media must be completely replaced. Replacement cycles for V-type filters are typically longer than for conventional filters.
    💡 Summary

    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.

    ❓ Frequently Asked Questions (FAQ)
    Q What is a V-Type Activated Carbon Filter and how does it differ from a conventional filter?
    A V-Type Activated Carbon Filter features a unique V-shaped carbon bed design that is narrow at the top and wide at the bottom. Unlike conventional filters with uniform packing, this design promotes even flow distribution, reduces channeling and pressure drop, and maximizes carbon utilization — resulting in higher efficiency and longer service life.
    Q What types of pollutants can the V-Type Activated Carbon Filter remove?
    The filter can handle a wide range of pollutants depending on the activated carbon type selected: Type A targets VOCs and ozone; Type B addresses acidic gases such as SO₂, NO₂, H₂S, HCL, and HF; Type C handles alkaline gases such as NH₃ and amines. This makes it suitable for chemical workshops, hospitals, laboratories, and HVAC systems.
    Q How often does the activated carbon need to be replaced?
    Replacement is required when the adsorption capacity is fully saturated and cannot be restored through backwashing or regeneration. V-type filters generally have longer replacement cycles than conventional filters due to their optimized bed design and improved carbon utilization. Monitoring effluent quality indicators such as residual chlorine, COD, and TOC will help determine the right replacement timing.
    Q What is the correct backwashing procedure for the V-Type Activated Carbon Filter?
    Backwashing should be performed in the bottom-to-top direction to remove trapped suspended solids and loosen the carbon bed. It is triggered when the inlet-to-outlet pressure differential reaches a set threshold (typically 0.05–0.1 MPa). The intensity and duration of backwashing must be carefully controlled to prevent activated carbon loss from the filter bed.
    Q What efficiency range does the V-Type Activated Carbon Filter offer?
    The filtration efficiency typically ranges from 2.0 to 4.0, depending on the carbon content and configuration. The appropriate efficiency level can be selected based on specific application requirements. Rational selection of both filter efficiency and face velocity ensures comprehensive economic benefits for the system.
    Q Can the V-Type Activated Carbon Filter be customized for specific applications?
    Yes. The filter size, activated carbon type, and technical specifications are designed based on the specific characteristics of the medium being treated — including flow rate, pollutant concentration, pH, temperature, and available system space. Custom sizing is supported to meet individual project requirements.
