The core strength of this filter is its superior adsorption capacity,efficiently dechlorinating water to protect downstream RO membranes from oxidant damage.It excels at removing dissolved organic matter(e.g.,humic acids)and substances causing color and odor.It uses nut shell,coal-based,or coconut shell activated carbon,each with distinct adsorption properties for different water qualities.The unit includes an efficient backwash system to periodically remove accumulated suspended solids and prevent bed compaction.The activated carbon media requires periodic replacement or regeneration to maintain adsorption efficiency.

Vessel materials are often Fiberglass Reinforced Plastic(FRP),304,or 316 Stainless Steel.The media is typically coconut shell activated carbon(Iodine Value≥1000)or coal-based carbon,with a bed depth of 1.2-2.0 meters.Empty Bed Contact Time(EBCT)is a key design parameter,usually 10-15 minutes.Operating pressure ranges from 0.25-0.6 MPa,with a design temperature below 50°C.Port sizes vary from DN50 to DN300.Control systems can integrate differential pressure gauges and timers for automatic backwashing.
Primarily used as pre-treatment for RO systems to remove residual chlorine and organics;serves as a pre-treatment unit in electronics ultra-pure water production;used in the food and beverage industry to improve process water quality;employed in chemical and pharmaceutical industries to remove trace contaminants and for decolorization;and widely applied in municipal and commercial building water purification for enhancing drinking water's sensory properties.
