Sewa­ge sludge dry­ing as a heat uti­li­sa­ti­on concept

In order to use the sur­plus heat from the com­bus­ti­on of bio­gas, a sewa­ge sludge dry­ing plant was built next to the bio­gas plant. It accepts sewa­ge sludge from the regi­on, which has been dewa­te­red to high solids con­tent using cen­tri­fu­ges and cham­ber fil­ter pres­ses. Air is used for dry­ing, which is hea­ted befo­re the dry­er. The exhaust air is clea­ned in several sta­ges. After a reten­ti­on time of about two hours, the dried sewa­ge sludge is con­vey­ed to the desi­gna­ted sto­rage area by means of a dischar­ge screw. The dried sewa­ge sludge is then uti­li­sed for energy.

At this plant, sewa­ge sludge is dried inde­pendent­ly and then ther­mal­ly uti­li­sed. The plant sup­plies its­elf with electri­ci­ty via a steam turbine.

The exhaust air from the dry­er is clea­ned via a multi-stage exhaust air scrub­ber. The was­te gas from the inci­nera­ti­on is used ther­mal­ly and clea­ned via the dry flue gas clea­ning system.

The decen­tra­li­sed natu­re of the plant avoids long trans­port rou­tes and thus saves CO2. In addi­ti­on, the phos­pho­rus can be reco­ve­r­ed from the ash and retur­ned to the natu­ral cycle.
