Tertiary-Treated Municipal Wastewater is a Significant Point Source of Antibiotic Resistance Genes Into Duluth-Superior Harbor [PDF]

open access: yes, 2011
In this study, the impact of tertiary-treated municipal wastewater on the quantity of several antibiotic resistance determinants in Duluth-Superior Harbor was investigated by collecting surface water and sediment samples from 13 locations in Duluth ...

Triblock Polymer Engineering Enables Hydration‐Rich, High‐Performance, Fouling‐Resistant Interfaces

open access: yesAdvanced Functional Materials, EarlyView.
A molecularly engineered triblock polymer (PHZ) rapidly reorganizes into a hydration‐rich interfacial layer on diverse surfaces, strongly suppressing hydrophobic attraction and fouling. The triblock polymer provides robust energy and steric barriers to oily foulants, enabling high‐performance antifouling at ultralow dosage.

Assessment of the possibility of using flocculation to improve properties of ultrafiltration membranes used in the purification of swimming pool water system washings

open access: yesE3S Web of Conferences, 2017
The paper presents the possibility of using an in-line mode flocculation–ultrafiltration system for the purification of backwash water from flushing the beds of pressure filters used in the indoor swimming pool water treatment circulation.

Influent Wastewater Microbiota and Temperature Influence Anaerobic Membrane Bioreactor Microbial Community [PDF]

open access: yes, 2016
Sustainable municipal wastewater recovery scenarios highlight benefits of anaerobic membrane bioreactors (AnMBRs). However, influences of continuous seeding by influent wastewater and temperature on attached-growth AnMBRs are not well understood. In this

The impact of process variables on the removal of PBDEs and NPEOs during simulated activated sludge treatment [PDF]

open access: yes, 2007
Sewage effluent is known to be a major source of endocrine disrupting compounds entering the aquatic environment. More efficient wastewater treatment could reduce the environmental load but, in order to achieve this factors determining compound behaviour

Balancing Electrons to Break the Activity‐Selectivity Trade‐Off in H2O2 Electrosynthesis

open access: yesAdvanced Functional Materials, EarlyView.
Carrier‐concentration balancing in CuS is achieved by coupling cobalt dopants with cobalt vacancies, converting CuS from p‐ to n‐type to accelerate 2e− ORR while withdrawing excess carriers to optimize *OOH binding for H2O2 desorption. The catalyst reaches 8.14 mol g−1 h−1 with >84% selectivity in 1.0 M KOH and drives robust electro‐Fenton dye ...

Structural and Chemical Engineering of Sub‐Nanochannel Membranes Toward Ion Selectivity

open access: yesAdvanced Functional Materials, EarlyView.
This review summarizes recent advances in structural and chemical engineering of sub‐nanochannels for ion selectivity. We first introduce fundamental ion transport mechanisms within sub‐nanochannels, followed by strategies to tune pore size, geometry, and surface functionalities, categorized into charge‐based, ion‐recognition, hydrophilic bonding, and ...

Location and chemical composition of microbially induced phosphorus precipitates in anaerobic and aerobic granular sludge [PDF]

open access: yes, 2012
This work focuses on combined scanning electron microscopy and energy dispersive X-ray analysis (SEM-EDX) applied to granular sludge used for biological treatment of high-strength wastewater effluents. Mineral precipitation is shown to occur in the core

An Edible H2O2 Biosensor for Gastrointestinal Metabolites and Peroxidase Enzyme Quantification

open access: yesAdvanced Healthcare Materials, EarlyView.
We present an edible biosensor for gastric fluid analysis that integrates a caffeic acid–horseradish peroxidase redox system into an edible electrolyte‐gated transistor. The device enables rapid, low‐volume detection of H2O2 and, with minimal modification, metabolites and enzyme activity in simulated gastrointestinal conditions.
