From:The Ohio Journal of Science (Vol. 103, Issue 1) Peer-Reviewed3:30 This paper describes the investigation of the effect of selected heavy metals on the treatment performance of activated sludge process. Oxygen uptake rates were measured and heavy metal speciation was determined...
-
From:Australian Journal of Soil Research (Vol. 41, Issue 1) Peer-ReviewedThe disposal of wastewater treatment sewage sludge onto agricultural land in New Zealand has led to the development of guidelines for the upper limit concentrations for total heavy metals in the underlying soil....

From:International Journal of Agronomy (Vol. 2017) Peer-ReviewedSewage sludge and green manure have become widely used organic amendments to croplands in many regions of the world. However, the amending effect of the combination of sewage sludge with green manuring in reclaimed...
-
From:Journal of Environmental and Public Health (Vol. 2017) Peer-ReviewedUse of Ecological Sanitation (EcoSan) sludge is becoming popular due to increasing price of organic fertilizers in Malawi; however, there is little evidence on the associated risks. Quantitative microbiological risk...

From:Journal of Environmental Health (Vol. 70, Issue 7) Peer-ReviewedThe authors investigated the antimicrobial resistance of Escherichia coli isolates in 22 samples of crude inflow, treated effluent, and sludge collected at the wastewater treatment plants of eight poultry...
-
From:The American Midland Naturalist (Vol. 140, Issue 2) Peer-ReviewedConcentrations of heavy metals in old-field plant species were compared among untreated reference subplots, unlimed sludge-treated subplots and limed sludge-treated subplots during the 4th yr of ecosystem recovery...

From:Archaea (Vol. 2018) Peer-ReviewedThe oilfield soil was contaminated for years by large quantities of aged oil sludge generated in the petroleum industry. In this study, physicochemical properties, contents of main pollutants, and fungal diversity of...
-
From:Advances in Environmental BiologyPeer-ReviewedThe cyclic ether 1,4 dioxane is a carcinogenic, emerging micropollutant present in water and wastewater. The treatment methods are ineffective due to its high solubility (low Henrys law constant 5 x [10.sup.-6] atm...
-
From:Advances in Environmental BiologyPeer-ReviewedFurfural is used as a solvent in most refineries. The objective of this study is to make an activated sludge system to reduce furfural concentration in an industrial-oily wastewater. The used wastewater was from Behran...
-
From:Archives of Industrial Hygiene and Toxicology (Vol. 63, Issue 3) Peer-ReviewedIn this study we compared three methods for the treatment of electroplating sludge highly loaded with zinc and iron: (1) calcium oxide-based solidification/stabilisation; (2) conversion into inert material by adsorption...

Nursery growing media: agronomic and environmental quality assessment of sewage sludge-based compost
There is a stringent need to reduce the environmental impact of peat in the plant nursery production chain. In this experiment, the use of different rates of sewage sludge compost in the preparation of growing media for... -
From:BioMed Research International (Vol. 2018) Peer-ReviewedA modified single sequencing batch reactor (SBR) was developed to remove the nitrogen of the real landfill leachate in this study. To take the full advantage of the SBR, stir phase was added before and after aeration,...
-
From:Chemical EngineeringPeer-ReviewedFats, oil and grease (FOG) waste can create environmental problems for water-treatment and sewage systems, but can be a potential resource if collected and separated efficiently. A technology originally developed by...
