Intensification of Ammonia Removal from Drinking Water with a Modified Zeolite Biological Filter Reactor

Abstract:

A novel modified zeolite bio-filter reactor was used for ammonia removal from drinking water, and inoculated nitrobacteria was combined with modified zeolite in this bio-filter reactor. The effects of various operation factors on the performance of the modified zeolite bio-filter reactor were investigated. The optimum operation conditions of the modified zeolite bio-filter reactor were obtained as follows: a HLR of 0.9 m³/ (m².h), the temperature ranged from 15°C to 30°C, and no-aeration. Under these optimal conditions, the outlet concentration of ammonia was less than 0.5 mg/L, even when an initial ammonia concentration of 6 mg/L.
