An Integrated Approach to the Biological Reactor–Sedimentation Tank System
Resources, 2019 Secondary clarifiers are demanded to separate solids created in activated sludge biological processes to achieve both a clarified effluent and to manage the biological processes itself.

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

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.

Structured model of bacterial growth and tests with activated sludge in a one-stage and two-stage chemostat [PDF]
, 1979 A kinetic model for a growing culture of micro-organisms was developed that correlated the biochemical structure of cells with quantitative physiological behaviour.

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.

Study on Preparation of Activated Carbon from Pyrolusite-Added Sewage Sludge
工程科学与技术, 2011 :Abstract: Activated carbon was prepared from pyrolusite-added sewage sludge by ZnCl2 activation method. Its structure and performance were characterized by BET, SEM, FT-IR, XRD, O2-TPO and TGA, and the impact of pyrolusite to preparing process of ...

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.This study investigates Spanish broom (Spartium junceum) as a renewable source for electrospun composite membranes in sustainable water purification. MCC and biochar were functionalized with eco‐friendly precursors and nanomaterials (i.e., HNT, β‐CDs) to develop hybrid PVA nanofiber composites.

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.This work developed a low‐temperature sludge hydrothermal coupled with gel crosslinking strategy which could upgrade the waste liquid generated from sewage sludge hydrothermal treatment into the hydrothermal‐liquid‐gel. The inventive hydrothermal‐liquid‐gel exhibited the enhanced pollutant removal capability, high synthetic stability, and superior ...
