Directive 91/271/EEC 7 seeks to harmonise measures relating to the treatment <strong>of</strong><br />
wastewater at Community level in order to protect the environment from any adverse<br />
effects due to discharge <strong>of</strong> such waters [42].<br />
5.1.8. Removal and collection <strong>of</strong> the composting end product<br />
The removal and collection <strong>of</strong> compost was perfomed on the 30 th day <strong>of</strong> the<br />
composting process through the removal portals that are situated at the bottom part <strong>of</strong><br />
the bioreactor. To facilitate the discharge <strong>of</strong> the end product the agitation system was<br />
operated for small intervals. The compost was collected manually using shovels and it<br />
was used as filling material to the bi<strong>of</strong>ilter bed.<br />
5.1.9. Sampling and analysis <strong>of</strong> the produced compost<br />
In order to evaluate the quality <strong>of</strong> the end product resulting from the 1 st composting<br />
trial a series <strong>of</strong> parameters were examined. Table 8 presents the physicochemical<br />
properties <strong>of</strong> the compost produced from the raw material shown in Table 5 which<br />
aquire the characteristics presented in Table 2.<br />
