This sludge is an aqueous mass of microorganisms that process nutrients from the wastewater.
\nAfter mechanical dewatering, a high water content remains. By adding polymer, the sludge becomes solid and can then be dried. Dried sewage sludge loses up to 80% of its volume and weight, which significantly reduces transport and disposal costs.[\/vc_column_text][\/vc_column][\/vc_row][vc_row gap=”35″ padt=”20″ padb=”100″ content_placement=”middle” el_class=”gap”][vc_column width=”1\/3″][vc_single_image image=”2001″ css=”” el_class=”pad_b30″][\/vc_column][vc_column width=”2\/3″][vc_custom_heading text=”Sewage Sludge Pyrolysis” farbe=”blau” fontsize=”fs25″ schriftschnitt=”bold” css=”” el_class=”marg_b20″][vc_column_text fontsize=”fs18″ css=””]Dried sewage sludge consists largely of dead microorganisms and thus of carbon compounds.
