Abstract

The consequences of indiscriminate discharge of wastewaters containing high concentrations of NH4-N into receiving wastewaters include; eutrophication of bodies of water, toxicity to stream biota, and impairment of water treatment processes. The biological process of nitrification can be applied to a variety of wastes provided the environmental conditions are appropriate for the growth of nitrifying organisms. Since the process of nitrification depends on the metabolism of nitrifying bacteria, it is imperative that they be present in adequate numbers to achieve the oxidation of NH4-N in a reasonable time. Few taxonomic and enumerative studies on nitrifying organisms in wastewater have been performed; mainly because of the cumbersome procedures involved. [...]
