Decen­tra­li­sed sewa­ge sludge utilisation

Indi­vi­du­al solu­ti­ons for ener­gy-auto­no­mous dry­ing and mono-inci­ne­ra­ti­on lay the foun­da­ti­on for more inde­pen­dence in sewa­ge sludge utilisation.

Decen­tra­li­sed sewa­ge sludge utilisation

Werk­stät­ten hea­ting-sys­tems GmbH’s decen­tra­li­sed recy­cling con­cept is the logi­cal con­se­quence of the ste­adi­ly incre­asing sludge dis­po­sal pres­su­re and inno­va­ti­ve inci­ne­ra­ti­on tech­no­lo­gy. A com­bi­na­ti­on of dry­ing and inci­ne­ra­ting the sludge at its own site also allows smal­ler muni­ci­pa­li­ties and was­te­wa­ter asso­cia­ti­ons to ope­ra­te inde­pendent­ly. Jour­neys and sto­rage are saved in terms of envi­ron­men­tal pro­tec­tion and cost reduc­tion. Werk­stät­ten hea­ting-sys­tems GmbH is clo­se­ly con­nec­ted to Werk­stät­ten GmbH under the umbrel­la of the Werk­stät­ten Group and com­ple­ments our ran­ge of ser­vices with exper­ti­se and years of expe­ri­ence in the are­as of com­bus­ti­on tech­no­lo­gy, bio­mass fuel sales and rene­wa­ble ener­gies. Our cus­to­mers bene­fit from the syn­er­gies achieved.

Cus­to­mi­sed sys­tem solutions

Depen­ding on loca­ti­on, inte­rests and cur­rent requi­re­ments, the abo­ve modu­les can be com­bi­ned as desi­red. From com­ple­te turn­key solu­ti­ons, inclu­ding ope­ra­tor models, to the sup­p­ly of indi­vi­du­al core com­pon­ents, such as a rota­ry kiln with flue gas clea­ning, we stand by our customers.

Decen­tra­li­sed dry­ing and inci­ne­ra­ti­on can be expan­ded in stages and in a modu­lar fashion. Cas­ca­ding 500 kW rota­ry boi­lers crea­te red­un­dan­cy and fle­xi­bi­li­ty in terms of annu­al ton­nes as popu­lar sca­les that allow per­mits wit­hout public participation.

Spe­cial features

  • Regio­nal recy­cling on site redu­ces sewa­ge sludge tou­rism and streng­thens independence
  • Ener­gy self-suf­fi­ci­ent and unman­ned over­all concept
  • Modu­lar­ly expan­da­ble via cascading
  • Com­ple­te burn­out of ashes due to con­troll­a­bi­li­ty of the resi­dence times
  • Water-coo­led, rota­ting com­bus­ti­on cham­ber pre­vents slag­ging of the ashes
  • Inci­ne­ra­ti­on ash recy­clable for P‑recovery
  • Homo­ge­neous com­bus­ti­on pro­cess despi­te fluc­tua­ting calo­ri­fic values and ash content
  • Com­ple­te oxi­da­ti­on of the flue gases in down­stream afterbur­ner chamber
  • Small space requi­re­ment due to smart sys­tem size
