Benefits of a 3D geological model for major tunnelling works : an example from Farringdon, east-central London, UK [PDF]

, 2012
In the design of major construction works, the better the ground conditions are known, the more control there is on the assessment of risks for construction, contract and personnel, and ultimately on final costs. Understanding of the ground conditions is

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 ...

Integrated remediation through solidification and dewatering of contaminated soil from laboratory investigation to in-situ application

Soils and Foundations
Solidification/stabilization of heavy metal contaminated soils often falls short of achieving the desired quality due to challenges in effectively controlling mixing uniformity. Optimization of mixing equipment and construction technology is a common way

Current state of fine mineral tailings treatment: A critical review on theory and practice [PDF]

, 2014
The mining industry produces fluid fine mineral tailings on the order of millions of tonnes each year, with billions of tonnes already stored globally. This trend is expected to escalate as demand for mineral products continues to grow with increasingly ...

Geological and geotechnical challenges on the Great Dyke of Zimbabwe and their impact on hardrock pillar design

Deep Underground Science and Engineering, EarlyView.
The Great Dyke of Zimbabwe is notable for its rich platinum group metal deposits but poses significant geological and geotechnical challenges due to its complex rock types and structural features. Traditional pillar design methods are insufficient for addressing these complexities; the study suggests incorporating advanced techniques such as machine ...

The Effectiveness of Potassium Permanganate in Oxidizing Hydrogen Sulfide and in Aiding Mechanical Dewatering of Pulp and Paper Industry Sludges [PDF]

, 1983
Introduction Odorous compounds have long been a significant problem faced by mills treating their own wastewater. This problem can be compounded when mechanical dewatering equipment is used to process primary and secondary sludges.

Dewatering combined with Moringa oleifera extract coagulation for industrial‐grade cassava starch concentration

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract Background Efficient dewatering is a critical step in cassava starch production because the moisture content of the concentrated slurry directly affects downstream drying costs and overall process efficiency. Conventional concentration routes, including sedimentation and centrifugation, often provide limited cake dryness and can increase ...

An integrated social and natural sciences case study for the reuse of organic wastes as soil amendments

PLANTS, PEOPLE, PLANET, EarlyView.
Reusing organic waste materials, such as animal manure, as soil amendments reduces water and fertiliser demand, contributing to achieving the Sustainable Development Goals. However, organic wastes may contain contaminants of emerging concern (CECs), posing potential ecosystem and human health risks. Despite the importance of this issue, there is a lack

Moderate‐Temperature Hydrothermal Treatment Removes Detectable DNA and Antibiotic Resistance Genes From Municipal Sludge While Preserving Resource Value

Water and Environment Journal, EarlyView.
This graphical abstract shows the overall study design where dewatered wastewater sludge samples were collected and subjected to a range of HT temperatures. Measurement of nucleic acid concentration and antibiotic resistance gene profiles across temperatures showed that HT at moderate temperatures offers sustainable, scalable sludge sanitation and ARG ...
