produced from the best anthracite mined in China, and are sold throughout the world.
All of our Anthracite Filter meets the standard of AWWA-B100 or JWWA-A-103.
Long time age, people had found the potential of anthracite for water treatment, but
anthracite coal was not used for this purpose until the beginning of the 20th century.
Crushed Anthracite makes an excellent medium density filtration media.
Our anthracite is specially selected for water treatment, and its production goes through
strict inspections. We have complete laboratory quality control analysis for effective size,
uniformity coefficient, specific gravity, acid solubility and hardness.
