Sludge recovery, recycling, treatment and disposal - Guidance on thermal treatment of sludge (ISO/TR 20736:2021)

This Technical Report describes good practice for the incineration and other organic matter treatment by thermal processes of sludges.
Thermal conditioning is excluded.
This Technical Report is applicable for sludges described in the scope of ISO/TC 275 specifically derived from:
—   storm water handling;
—   night soil;
—   urban wastewater collecting systems;
—   urban wastewater treatment plants;
—   treating industrial wastewater similar to urban wastewater;
It includes all sludge that may have similar environmental and/or health impacts but excludes hazardous sludge from industry and dredged sludge.

Predelava, recikliranje, obdelava in odlaganje blata - Navodilo za toplotno obdelavo blata (ISO/TR 20736:2021)

To tehnično poročilo opisuje dobro prakso sežiganja in drugih načinov obdelave organskega materiala s toplotnimi procesi obdelave blata.
Termično kondicioniranje je izključeno.
To tehnično poročilo se uporablja za vrste blata, opisane v standardu ISO/TC 275, ki izvirajo iz:
– sistemov za zbiranje deževnice;
– vsebine greznice;
– zbiralnih sistemov za komunalno odpadno vodo;
– čistilnih naprav za komunalno odpadno vodo;
– čiščenja industrijske odpadne vode na podoben način kot komunalne odpadne vode.
Vključuje vse vrste blata, ki imajo lahko podoben vpliv na okolje in/ali zdravje, z izjemo nevarnega industrijskega blata in mulja iz rečnih strug.
