5. Postupak prema bilo kojem od prethodnih patentnih zahtjeva, naznačen time što se mulj snabdijeva sa dodatnim dvovalentnim željezom prije dodavanja sredstva za oksidaciju.
6. Postupak prema bilo kojem od prethodnih patentnih zahtjeva, naznačen time što je sredstvo za oksidaciju izabrano od najmanje jednog od vodikova peroksida, natrijeva per-karbonata i per-octene kiseline.
7. Postupak prema patentnom zahtjevu 6, naznačen time što je sredstvo za oksidaciju vodikov peroksid.
8. Postupak prema patentnom zahtjevu 7, naznačen time što se mulj snabdijeva vodikovim peroksidom kao sredstvom za oksidaciju u količini od 30-60 kg, 100% vodikova peroksida po toni suhih čvrstih supstanci.
9. Postupak prema bilo kojem od prethodnih patentnih zahtjeva, naznačen time što se mulj snabdijeva sredstvom koje potpomaže uklanjanje vode prije uklanjanja vode.
10. Postupak prema bilo kojem od prethodnih patentnih zahtjeva, naznačen time što se iz mulja prethodno uklanja voda centrifugom ili rotacijskim sitom.
11. Postupak prema bilo kojem od prethodnih patentnih zahtjeva, naznačen time što se voda iz mulja konačno uklanja centrifugom, pužnom prešom, komornom filter prešom ili trakastom filter prešom.
12. Postupak prema bilo kojem od prethodnih patentnih zahtjeva, naznačen time što se voda iz mulja uklanja do sadržaja čvrstih supstanci od najmanje 30 tež.%.
13. Postupak prema patentnom zahtjevu 12, naznačen time što se voda iz mulja uklanja do sadržaja čvrstih supstanci od 35-60 tež.%.
