Our coal-based granular activated carbon is widely used in urban water plants for primary and advanced purification of tap water. It effectively removes residual chlorine, disinfection by-products (DBPs), organic contaminants, odor and color, improving the safety and taste of drinking water for residents.
Ideal for secondary and tertiary wastewater treatment, including industrial effluent and domestic sewage. It adsorbs toxic organic compounds, heavy metals (e.g., lead, mercury, cadmium), ammonia nitrogen, and persistent pollutants, helping to meet discharge standards and reduce environmental impact.
For groundwater contaminated with volatile organic compounds (VOCs), pesticides, herbicides, and heavy metals, coal-based granular activated carbon provides reliable adsorption to restore water quality for potable or industrial use.
Used in seawater desalination plants as a pretreatment stage, our carbon removes organic matter, chlorine, algae-derived contaminants, and residual chemicals. This protects reverse osmosis (RO) membranes from fouling and degradation, extending system service life.
Suitable for water purifiers, filter cartridges, and direct drinking water systems. It eliminates residual chlorine, odor, bad taste, and trace organic pollutants in tap water, providing clean, safe drinking water for homes, offices, and public facilities.
Removes ammonia, nitrites, nitrates, organic waste, and odors in fish tanks and aquaculture ponds. It helps maintain stable water quality, reduce harmful substances, and create a healthy living environment for aquatic organisms.
A: It is coal-based granular activated carbon, a mainstream adsorption material mainly used for water purification and various water treatment works.
A: It has excellent adsorption performance, high hardness, not easy to break, low cost and long service life, ideal for large-scale water purification projects.
A: Yes. Our coal-based granular activated carbon is suitable for household water purifier filter elements to remove residual chlorine, odor and impurities in tap water.
A: The service life depends on water quality and water flow. Normally, it can be used for 3–12 months, and replacement is recommended when adsorption capacity declines obviously.
A: Sure. We support customized particle size, iodine value, CTC and other parameters according to your actual usage demands.
