The reasons for the accumulation of man-made waste during years operation Baikal Pulp and Paper Mill, as well history construction filling storage facilities with waste, in particular sludge-lignin, are considered

background and purpose: disposing sludge from industrial wastewater treatment plants (iwwtps) is a serious issue because it can affect human and animals health, and also environmental quality. in this study, sludge from an iwwtp was analyzed regarding its physicochemical characteristics and disposal options. materials and methods: grab sampling was used to collect 12 sludge samples biweekly (ma...

It was recently discovered that vivianite (Fe3(PO4)2.8H2O) could be magnetically extracted from digested activated sludge which opened a new route for phosphorus recovery (Wijdeveld et al. 2022). While its formation in is regularly reported, it not yet studied fresh, undigested sludge. In particular, the extent to form during storage missing. The current research showed iron reduction completed...

Sludge generated in waste water treatment process can be a major sink for some pharmaceutical and personal care products (PPCPs). The land application of sewage sludge (in the form of biosolids in the United States) can therefore potentially introduce PPCPs into the environment. After treatment, biosolids are often subjected to a storage period before land application. However, little informati...

Activated sludges are an inoculum source commonly used in biodegradation studies, as wastewater treatment facilities constitute an entry point to the environment for many chemicals. In this paper, the main issues relating to the use of activated sludge in biodegradability tests are presented. Special attention is also devoted to discussing the factors affecting both the activity of the microbia...

Commercial swine waste lagoons are regarded as a major reservoir of natural estrogens, which have the potential to produce adverse physiological effects on exposed aquatic organisms and wildlife. However, there remains limited understanding of the complex mechanisms of physical, chemical, and biological processes that govern the fate and transport of natural estrogens within an anaerobic swine ...

Improved design strategies at BNR plants should include cost reductions so that the consumers and water authorities will be more willing to build EBPR plants instead of conventional activated sludge plants. Through efficient design, actual savings in construction and operation costs can be realized. For this reason, anaerobic stabilization of COD needs to be seriously considered during design f...
