At this location a reduced samplingand analysis programme was implemented in the course of three days in themonth of April 2002.The analysis results demonstrated the following:• The inlet analyses of the physical-chemical and bacteriological parametersdemonstrated exceptionally low values compared to a characteristic compositionof greywater.• Due to the low inlet level it makes nos sense to estimate the purificationefficiencies of the chemical parameters of the system. As to the bacteriologicalindicator parameters (bacterial count - growth at 22°C and 37°C -as well as Enterococci) the reduction was estimated at 17-83%.• The outlet from the cisterns does not meet the Danish quality requirementsfor drinking water with respect to the microbiological parameters,and, furthermore, three of the analyses do not meet the requirement forturbidity.• The reason for the increased content of microbiological indicator parametersat the treatment system at the location Virklund, afd. 47 mainlyis that the water does not undergo a UV treatment right before pumpinginto the cistern.Beyond the treatment results from Virklund, afd. 47, the experience base ismodest at present. The results from other full-scale plants and tests are illustratedin table F below.17
