Quality Standards

At our company, we adhere to international quality standards to meet the specific requirements of our customers. We follow ASTM's carbon standards for evaluating and testing activated carbon, which are widely recognized in industrial applications. These standards help determine the key physical and chemical properties of activated carbon, including pH reaction, particle size, adsorption capacity, and the content and activity of various chemical substances. To assess these properties, we utilize methods such as aqueous phase isotherm techniques, air jet sieving, micro-isotherm testing, ashing, and rapid small-scale column tests. These rigorous standards ensure that our activated carbon meets the highest safety and performance criteria, providing reliable and consistent results across diverse industrial applications. Apart from ASTM standards we also follow other standards such as AWWA: American Water Works Association &  JIS: Japanese Industrial Standards & etc for granular and powdered activated carbon based on Customer requirements.
