Decay of escherichia coli in soil following the application of biosolids to agricultural land [PDF]

, 2003
The decay of Escherichia coli in a sandy loam soil, amended with enhanced and conventionally treated biosolids, was investigated in a field experiment following spring and autumn applications of sewage sludge.

Tunable amylopectin graft copolymers for flocculating and dewatering iron ore tailings

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Polyacrylamide (PAM), the standard flocculant for mining tailings, often produces turbid supernatants and poorly dewatered sediments, limiting water reuse and tailings densification. We synthesized amylopectin‐graft‐poly[(2‐methacryloyloxy)ethyl]trimethylammonium chloride (AP‐g‐PMETAC) copolymers with systematically varied graft frequency (N =

Changes in concentrations and loads of total phosphorus in domestic and treated wastewater over a 15-year observation period in terms of limiting negative anthropopressure on the surface water quality - case study

Acta Scientiarum Polonorum. Formatio Circumiectus, 2020
Aim of the study: The main aim of the research was to prove the thesis, that formal and legal restrictions on the use of phosphorus compounds, particularly polyphosphates, in detergents significantly introduced in recent years reduced the concentration ...

Cellular and hormonal disruption of fetal testis development in sheep reared on pasture treated with sewage sludge

, 2005
The purpose of this study was to evaluate whether experimental exposure of pregnant sheep to a mixture of environmental chemicals added to pasture as sewage sludge (n = 9 treated animals) exerted effects on fetal testis development or function ...

Economic and environmental implications of the development of UASB reactors in Mexico for sustainable industrial wastewater treatment

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract The objective of this work is to demonstrate that the inclusion of an up‐flow anaerobic sludge bed (UASB reactor) within an industrial wastewater treatment plant reduces the plant's investment and operating costs compared to a system based solely on conventional complete‐mix activated sludge (CMAS), operating under the same design principles ...

Recycled biowaste as a source of infection [PDF]

, 2006
Biowaste and sewage sludge can be used as a fertiliser and soil amendment in agriculture. However if not treated efficiently before use, such products can contain microbial pathogens that pose a health risk for humans and animals. This study investigated

A Comprehensive Review of the Key Factors Affecting Biogas Production From Anaerobic Digestion of Organic Waste

CleanMat, EarlyView.
Efficient conversion of organic waste to biogas depends on the coordinated optimization of feedstock composition, pretreatment, operational parameters, reactor design, and microbial community dynamics. This review highlights how these interacting factors improve methane yield and process stability, advancing anaerobic digestion as a practical pathway ...
