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.

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.

Carbon‐Negative Upcycling of Sewage Sludge into Superiorly Stable Gel Via Liquid‐Phase Utilization Strategy for Water‐Remediation

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 ...

Tuning Cation Disorder in LiNi0.5Mn1.5O4 via Room Temperature Continuous‐Flow Co‐Precipitation and Controlled Heat Treatment

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
LiNi0.5Mn1.5O4 (LNMO) precursors were produced at room temperature by Ambient Continuous Turbulent In‐line Mixing (ACTIM) at rates of up to 0.42 kg h−1. The final heat treatment step at 650, 700, or 750 °C, altered cation disorder and the electrochemical behavior of the LNMO cathodes, while the effect of adding MWCNTs to the electrodes, was also ...

Bio‐Derived Carbon Nanoparticles: A Green Amendment for Alleviating Heavy Metals in Soil–Plant Systems

Land Degradation &Development, EarlyView.
ABSTRACT Heavy metal (HM) contamination of soil–plant systems poses persistent ecological and health risks, driving interest in nanoparticle‐based remediation. Although conventional chemically synthesized nanoparticles (CSNPs) are effective, their energy‐intensive production and residual toxicity limit sustainable deployment.

Causes and control of low F/M bulking in long sludge age nutrient removal activated sludge systems [PDF]

, 1993
Includes bibliography.A problem plaguing the greater proportion of nutrient removal activated sludge systems treating municipal sewage, is the prolific growth of :filamentous organisms (bulking), which inhibits the rate of sludge settling in the ...

Anaerobic Co-Digestion of Fats, Oils and Grease (FOG) with Waste Activated-Sludge

Chemical Engineering Transactions, 2012
Two mesophilic batch digestion runs were set-up in which a FOG is co-digested with waste activated sludge. FOG loadings range from 0 to 50 % of the VS. This co-digestion of FOG and activated sludge successfully increased the biogas production up to 400 %
