Pyrolysis and gasification at water resource recovery facilities: Status of the industry. [PDF]

Water Environ Res, 2022
Pyrolysis and gasification systems in wastewater treatment applications are garnering renewed interest. Rising costs for solid residual handling, emerging contaminants, and beneficial reuse of residuals provided technology suppliers incentive to overcome historical challenges associated with these thermal processes.

A proof-of-concept experimental study for vacuum-driven anaerobic biosolids fermentation using the IntensiCarb technology. [PDF]

Water Environ Res, 2022
Intermittent feed and vacuum extraction with the IntensiCarb reactor provide an avenue to recover water and volatile organics, while minimizing reactor volume. Abstract This study demonstrates the potential of an innovative anaerobic treatment technology for municipal biosolids (IntensiCarb), which relies on vacuum evaporation to decouple solids and ...

Use of Deep Sequencing to Evaluate Transitions in Microbial Communities in Stranded <i>Sargassum</i>. [PDF]

Int J Microbiol
Deep sequencing technologies can be used to evaluate pathogens in environmental samples. The objective of this study was to use this technology to evaluate Sargassum samples that were characterized by different stranding times, one classified as short‐term stranded (STS) and another classified as long‐term stranded (LTS) Sargassum.

Water, Water Everywhere, but Every Drop Unique: Challenges in the Science to Understand the Role of Contaminants of Emerging Concern in the Management of Drinking Water Supplies. [PDF]

Geohealth, 2023
Abstract The protection and management of water resources continues to be challenged by multiple and ongoing factors such as shifts in demographic, social, economic, and public health requirements. Physical limitations placed on access to potable supplies include natural and human‐caused factors such as aquifer depletion, aging infrastructure ...

Assessing the Ecological Risks of Per- and Polyfluoroalkyl Substances: Current State-of-the Science and a Proposed Path Forward. [PDF]

Environ Toxicol Chem, 2021
Abstract Per‐ and poly‐fluoroalkyl substances (PFAS) encompass a large, heterogenous group of chemicals of potential concern to human health and the environment. Based on information for a few relatively well‐understood PFAS such as perfluorooctane sulfonate and perfluorooctanoate, there is ample basis to suspect that at least a subset can be ...

Update of the risk assessment of polybrominated diphenyl ethers (PBDEs) in food [PDF]

EFSA J
Abstract The European Commission asked EFSA to update its 2011 risk assessment on polybrominated diphenyl ethers (PBDEs) in food, focusing on 10 congeners: BDE‐28, ‐47, ‐49, ‐99, ‐100, ‐138, ‐153, ‐154, ‐183 and ‑209. The CONTAM Panel concluded that the neurodevelopmental effects on behaviour and reproductive/developmental effects are the critical ...
