Thermal treatment of sewage sludge: One of possible disposal methods [PDF]

open access: diamondZaštita Materijala, 2014
Waste water treatment is a standard process in developed countries. It is intended to minimize the influence of waste water on the environment. The treatment process produces various remains that are generally called sewage sludge.

Effect of Sewage Sludge, Sewage Sludge Compost and Sewage Sludge Biochar on Heavy Metal and It Fractions

open access: yesInternational Journal of Environment and Climate Change
This study was conducted to evaluate the effect of sewage sludge (SS), sewage sludge compost (SSC) and sewage sludge Biochar (Sewchar, SC) on the heavy metal content and its fractions. The preparation of sewage sludge compost, Sewchar and incubation study were done in Completely Randomized Block Design.

Assessing metal contamination and speciation in sewage sludge: implications for soil application and environmental risk

open access: yesReviews in Environmental Science and Bio\/technology, 2023
Based on the most recently published data, we definitively estimated that the annual global production of sewage sludge may rise from ~ 53 million tons dry solids currently to ~ 160 million tons if global wastewater were to be treated to a similar level ...
