| Abstract: | The treating behaviors of the quartzite and zeolite modified by aluminium salt in removing the excessive fluoride in the drinking water are studied. The treating capacities between modified quartzite and modified zeolite are compared and analyzed. The results show that the zeolite, with preferable physical steric structure,has advantages as modifying filter media, and the efficiency of removing fluoride reaches morn than 98%, and the treating process is free of toxin and hazards. |
