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 ...

Green and sustainable synthesis of magnetite from copper slag via citrate complexation for methylene blue dye removal from water

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract This study proposes a novel, green, and sustainable method for synthesizing magnetic iron oxides from metallurgical copper slag (CS), leveraging its iron content as a valuable resource. Iron was extracted via acid leaching using edible citric acid (ECA), forming a citrate–iron complex (CSL), which was subsequently thermally decomposed at 300°C

Adsorption of 2, 4, 6-Trichlorophenol in Water by Nitrogen and Sulfur Co-doped Sludge Biochar

Taiyuan Ligong Daxue xuebao
Purposes 2, 4, 6-Trichlorophenol (2, 4, 6-TCP) has been listed in the blacklist of pollutants in water because of its strong toxicity and “three inducing” effects. It is of great significance to remove 2, 4, 6-TCP from water.

Utilization of durian peels (Durio zibethinus) and lubricant treatment sludge as raw materials of Refuse-Derived Fuel

Sustinere: Journal of Environment and Sustainability
Fossil energy is among the most widely utilized energy sources in Indonesian industry, but its continuous use is leading to its depleted. Refuse-derived fuel (RDF) offers an alternative made from organic and inorganic waste. Durian peel is identified as

Waste activated sludge high‐rate treatment of septage: Stabilization phase trials and comparison with winery wastewater treatment

The Canadian Journal of Chemical Engineering, EarlyView.
Performance evaluation of the waste activated sludge high‐rate (WASHR) process for septic wastewater treatment. Abstract The waste‐activated sludge high‐rate (WASHR) process is evaluated as a batch‐mode pre‐treatment for actual septage using a high‐rate contact stabilization (HRCS) approach.

Hydrogen donor‐assisted visbreaking of Canadian oil sands bitumen

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract High‐viscosity Canadian oil sands bitumen requires processing for efficient transportation and refining. Partial upgrading technologies, primarily based on thermal processing, can effectively reduce, or even eliminate, the use of costly diluent, increase bitumen quality and market value, potentially decrease greenhouse gas (GHG) emissions, and

Sulfate removal from wastewater by using waste material as an adsorbent

Open Engineering
A new composite adsorbent was created by activating bentonite, a sludge, to improve its adsorption capability. These innovative adsorbents address sulfate ion pollution in wastewater treatment. Researchers used various techniques to study the composite’s

A perspective on parsimonious hybrid models for online use: Augmenting fundamental models with ARIMA disturbances

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Hybrid models (HMs) combine fundamental model (FM) equations with empirical components. These models can lead to improved predictions because they reduce process/model mismatch and can account for phenomena that are not considered in the FM equations.
