Determination of reliable concentrations of pollutants in raw wastewater based on different sampling methods
Journal Title: Civil and Environmental Engineering Reports - Year 2013, Vol 1, Issue 10
Abstract
The aim of this study was to check the extent to which the sampling method and the volume of sewage (size of the wastewater treatment plant) influence the determined daily average concentrations of pollution components. Within three days of dry weather, the composition of two raw sewage wastewater treatment plants was continuously monitored. The WWTPs were designed for the flow of 820 m3/d and 51000 m3/d, respectively. The concentrations of pollutants were measured in samples taken both in time-proportional and flow-proportional ways. The obtained values show the possibility of taking the samples mixed at equal time intervals and in proportion to the flow as reliable sources for design values of concentrations. The size of WWTP, i.e. the amount of investigated raw sewage, was of no significant importance to the obtained results regarding concentrations of pollutants.<br/><br/>
