China Activated Carbon Filter System Suppliers - Industrial Water Treatment Equipment Manufacturer Factory

An activated carbon filter is an essential water treatment device widely utilized in various applications, especially in desalination systems. As a critical pre-treatment component, this filter effectively adsorbs residual chlorine that may not be eliminated during the initial filtration stages. By ensuring the removal of these harmful substances, it significantly extends the lifespan of downstream equipment, enhances water quality, and prevents potential contamination. This function is particularly vital for protecting reverse osmosis membranes and ion exchange resins from the toxic effects of free residual chlorine, Moreover, this activated carbon filter efficiently adsorbs various contaminants, including small molecular organic matter that can escape from upstream processes. Its remarkable adsorption capabilities also target odors, colloids, pigments, and heavy metal ions, contributing to a notable decrease in COD levels. Additionally, the filter plays a key role in maintaining the SDI value of RO inlet water below 5 and reducing TOC levels to less than 2.0 ppm, As a leading manufacturer in China, we pride ourselves on being a reliable supplier of high-quality activated carbon filters, produced in our state-of-the-art factory. Our commitment to excellence ensures that you receive superior water treatment solutions that meet your needs effectively

    Product Details

    Equipment Description

    The filter material of the activated carbon filter may include activated carbon, quartz sand, and gravel. The primary filter material is typically activated carbon, with quartz sand and gravel serving as cushion layers. Residual chlorine, colloids, and other small particles in water are primarily removed through the adsorption and reduction properties of activated carbon. Larger particles and suspended matter are filtered out via interstitial voids within the media layers.
    The equipment can be designed for either manual or automatic control, with the ability to switch between these modes. The automatic control system monitors and regulates all operational and process control points, enabling unattended and fully automated operation. The system employs a combination of air-water backwashing, with backwash wastewater being discharged. In the system design, concentrated water from the reverse osmosis process is utilized for backwashing, thereby enhancing water utilization efficiency.
    Backwashing of the filter can be initiated automatically based on either the backwashing time interval set by the central control system or the differential pressure setting at the filter inlet and outlet.
    The operational modes of the filter include water production, water backwashing, air backwashing, and forward washing. All operational modes are executed automatically according to pre-set programs.
