Industrial Activated Carbon Filter System Filter Sand Automat
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.
Equipment Features
- Effectively removes suspended solids and organic substances such as algae from raw water, reducing turbidity.
- Efficiently eliminates colloids and oxides from raw water.
- Incorporates a unique uniform water distribution system to maximize filtration efficiency, ensuring long-term compliance with downstream equipment turbidity requirements.
- Equipped with an air-scrubbing backwashing device, offering high capacity, short cycle times, and low water consumption.
- Utilizes high-quality ABS or stainless steel water caps and premium filter materials to ensure excellent filtration performance without layer mixing during backwashing.
- Features inlet and outlet differential pressure switches that enable automatic backwashing based on preset operating differential pressure values.
- System design incorporates concentrated water from downstream devices for backwashing, improving overall water utilization.
