Diffusion and Reaction in Biological Nitrification
The effect of internal diffusional resistances on the rate of nitrification is analyzed theoretically and experimentally. A model for internal diffusion and simultaneous reaction is described,...

Factors Affecting Nitrification
Experiments were conducted to determine the effects of various factors upon the rate of nitrate production by a stock culture of nitrifying bacteria. Actively metabolizing heterotrophic...

Salt Removal Efficiencies on Land Disposal of Swine Waste
Swine waste aerobic lagoon effluent was sprinkled overland and the runoff water was collected. Both the waste effluent and the runoff water were analyzed for nitrate, ammonia, chloride,...

Denitrification Using Thiosulfate and Sulfide
Autotropic denitrification using enriched cultures of Thiobacillus denitrificans was investigated. Thiosulfate and sulfide were used as electron...

Ozone Effect on Nitrogenous Matter in Effluents
A study of the effect of ozone on various nitrogenous compounds found in effluents was undertaken using two systems: (1)Effluents after lime treatment; and (2)solutions of specific nitrogenous...
