Untreated wastewater samples were collected from the Great Lakes Water Authority (GLWA) Resource Recovery Facility (WRRF) located in southeast Michigan between April 8 and May 26, 2020. The WRRF is largest single-site treatment facility US, it receives its service area via three main interceptors: Detroit River Interceptor (DRI), North Interceptor-East Arm (NI-EA), Oakwood-Northwest-Wayne County (O-NWI). A total of 54 untreated (18 per interceptor) at point intake into WRRF. Viruses isolated...
Our knowledge of PFAS fate and transport in the urban water cycle between treatment plants (WTPs) wastewater (WWTPs) is dependent upon analytical methodology. To conduct a mass balance through these engineered systems, environmental chemistry must be leveraged to quantify various media that facilities. Although balances have been attempted across unit processes for small selection WTPs WWTPs, system-wide are daunting challenge not achieved date. The continued existence legacy constantly...
There is an increasing global interest in scaling up urban agriculture (UA) its various forms, from private gardens to sophisticated commercial operations. Much of this the spirit environmental protection, with reduced waste and transportation energy highlighted as some proposed benefits UA; however, explicit consideration resource requirements needs be made order realize these anticipated benefits. A literature review undertaken here provide new insight into implications UA cities...
Successfully addressing the complex global sanitation problem is a massive undertaking. Anaerobic digestion (AD), coupled with post-treatment, has been identified as promising technology to contribute meeting this goal. It offers multiple benefits end users, such potential inactivation of pathogenic microorganisms in waste and recovery resources, including renewable energy nutrients. This feature article provides an overview most frequently applied AD systems for decentralized communities...
Perfluoroalkyl and polyfluoroalkyl substances (PFAS) are an emerging issue in wastewater treatment. High-temperature thermal processes, incineration being time-tested, offer the opportunity to destroy change composition of PFAS. The fate PFAS has been documented through sludge incinerators, including a multiple hearth furnace (MHF) fluidized bed (FBF). dewatered feedstock averaged 247- 1280-μmol targeted per sample run MHF FBF feed, respectively. Stack emissions (reportable for all from...
Per- and polyfluoroalkyl substances (PFAS) are compounds of emerging concern based on ubiquitous distribution potential human health impacts. Whereas manufacturing plants fire-training/suppression areas recognized as primary sources PFAS contamination the environment, understanding role water treatment (WTPs) resource recovery facilities (WRRFs) in cycling is important. Literature presence pathways within between WTPs WRRFs was reviewed synthesized to address this knowledge gap. The...
An anaerobic dynamic membrane bioreactor (AnDMBR) mimicking rumen conditions was developed to enhance the hydrolysis of lignocellulosic materials and production volatile fatty acids (VFAs) when treating food waste. The AnDMBR inoculated with cow content operated at a 0.5 day hydraulic retention time, 2–4 solids temperature 39 °C, pH 6.3, characteristics similar those rumen. Removal rates neutral detergent fiber acid 58.9 ± 8.4 69.0 8.6%, respectively, VFA yield 0.55 0.12 g as chemical oxygen...
While rumen microorganisms are known to facilitate the hydrolysis of lignocellulosic substrates in anaerobic digestion (AD), it is unclear how content can be used maintain continuous-flow AD systems. We as either an inoculum or a cosubstrate two separate experiments, and performed microbial multivariate statistical analyses study best use this resource enhance AD. Hydrolytic bacteria such Fibrobacter spp. remained present for months reactor operation when was inoculum, producing 0.3–0.5 g...
Hydrothermal liquefaction (HTL) liquifies wet feedstocks to produce a biocrude under moderate temperatures (300–450 °C) and high pressures (>2500 psi). The can be upgraded transportation fuels (predominantly diesel) using typical refinery unit operations (e.g., hydrotreater distillation). HTL of wet-wastes is promising route environmentally friendly cost-competitive fuels; however, the feedstock significantly impacts product quality process yield. Consequently, it important rigorously...
Solids from wastewater treatment undergo processing to reduce mass, minimize pathogens, and condition the products for specific end uses. However, costs contaminant concerns (e.g., per- polyfluoroalkyl substances [PFAS]) challenge traditional landfill land application practices. Incineration can overcome these issues but has become complicated due evolving emissions regulations, it suffers poor public perception. These circumstances are driving re-emergence of pyrolysis gasification...
Waste streams continuously introduce active and inactive microbial populations that can influence assembly of communities in chain elongation systems.
ABSTRACT An anaerobic dynamic membrane bioreactor (AnDMBR) was used to mimic rumen conditions enhance the hydrolysis of lignocellulosic materials and production volatile fatty acids (VFA) when treating food waste. The AnDMBR inoculated with cow content operated at a 0.5-day hydraulic retention time, 2 4-day solids temperature 39 °C, pH 6.3, characteristics similar those rumen. operational strategy repeating settle-permeate-mix cycles utilized simulate regurgitation ruminant animals.

A Surveillance Study: Per-and polyfluoroalkyl Substances (PFAS) in BiosolidsAbstractThis surveillance study was aimed at understanding concentrations of PFAS biosolids. To address this objective, samples were collected from twenty-five wastewater resource recovery facilities (WRRFs) throughout North America over a six-month period. minimum two each WRRF: Location – sludge entering the stabilization process, and B biosolids (post-stabilization sludge). Modified EPA Method 537.1 used to...
