YK-AC
purestar
YK-AC starts with high-density premium granular coconut shell carbon processed through controlled steam activation to develop a uniform micropore structure with high adsorption capacity. The carbon then undergoes multi-stage deep acid washing and deionized water rinsing to remove soluble mineral ash, metal ions and silica residues from the carbon matrix, achieving ultra-low extractable impurity levels.
As granular coconut shell activated carbon instead of extruded pellets, YK-AC delivers high mechanical strength, low pressure drop and excellent bed uniformity in deep-bed filtration systems. Its neutral effluent pH and minimal leachable metals make it ideal for condensate polishing where even trace levels of ionic contamination can cause boiler corrosion and reduce turbine efficiency. The product is also widely used in semiconductor UPW systems and pharmaceutical water for injection (WFI) pretreatment.
