Abstract

Our paper presents results of nutrient removal from household wastewater in the bioreactors with nonwoven filters. The experimental system was constructed from two groups of bioreactors in laboratory scale with gravity-fed wastewater supply. The variable differentiating the work of both tested systems was the method of sewage dosing. In both experimental groups, there was a statistically significant reduction ratio of nitrite nitrogen, ammonia nitrogen, phosphate, and sulfide ions. In spite of the marked difference between concentrations of investigated nutrients in treated wastewater between the experimental groups was not possible to demonstrate in most cases the statistically significant differences. The bioreactors fed once every 12 hours showed an additional effect of desiccation of part of a nonwoven filter and a significant deterioration in the quality of treated sewage. The tested systems of reactors provide the scientific promises for their use on an industrial scale as a system with partial treatment of household sewage. The contents of nutrients in treated wastewater, however, still exceeds the permissible level specified in the standard for treated sewage.
