Ammonia removal characteristics by biofilter using inorganic carriers seeded with nitriifying bacteria enriched from night soil sludge
Yani, Mohamad | Hirai, Mitsuyo | Shoda, Makato (1998)Production Ammonia removal by biofilters was conducted mainly using organic packing-materials as a carrier like peat (1,2) or wood bark (3), but inorganic packing materials (4,5) were rarely used. In this study, as inorganic ... -
Enhancement of Ammonia Removal in Peat Biofilter Seeded with Enriched Nitrifying Bacteria
Yani, Mohamad | Hirai, Mitsuyo | Shoda, Makoto (2000)Night soil sludge was enriched to foster nitrifying bacteria by tile addition of ammonium sulfate, and the enriched mixed culture of nitrifying bacteria obtained was inoculated to peat. Ammonia gas was introduced to the ...
