Irrigation with Treated Wastewater: Potential and Limitations
… population creates greater quantities of wastewater and demands greater quantities of food, so an obvious connection arises. However logical wastewater reuse may be for bridging the irrigation supply-demand gap in this arid region, significant limitations prevent widespread adoption. The …

Implementing a treated wastewater recharge technique and reverse osmosis unit system for water sustainability
… brackish groundwater in conjunction with treated wastewater augmentation and a reverse osmosis unit. The dissertation considered two types of simulation models for the conceptual design system approach. These models are the lump model approach and the areal distribution model approach. The …

The effect of treated wastewater effluent on the water quality of the Natalspruit river
Lack of effective wastewater management strategies poses a serious threat to the environment and human health around the world. South Africa's freshwater resources are threatened by human influence and dwindling at an alarming rate. Global climate change is expected to exacerbate this stress unless …

BACTERIAL BIOFILM FORMATION AS A TOOL TO ASSESS CHEMICALLY TREATED WASTEWATER QUALITY IN DEEP EAST TEXAS
<p>The effectiveness of wastewater treatment plants (WWTPs) relies on a sequence of primary, secondary, tertiary, and advanced treatment stages to remove contaminants. However, despite these processes, microbes can still thrive in treated water from WWTP, posing a significant threat to water …

Analysis of Aquifer and Operational Conditions for Successful Soil Aquifer Treatment of Treated Wastewater via Synthesis of Published Full-Scale and Laboratory-Scale Studies
<p>Soil aquifer treatment (SAT) of treated wastewater performance was evaluated across published full-scale and lab-scale studies developing insights on the aquifer and operational factors that affect SAT efficacy. The goal of this study was to develop a basis for predicting the contaminant removal …

Recycling of domestic wastewater treated byvertical-flow wetlands for irrigating crops
… interest in recycling various nutrient-rich wastewater streams, such as treated urban wastewater, for irrigation in the agricultural sector. The aim is therefore to assess if domestic wastewater treated by different sustainable wetland systems (some contaminated by diesel spills) can be …

Impact of wastewater reuse in Burlington County on surface water quality and adjacent wetlands
… potential ecological impacts from application of treated wastewater effluent. Indian Springs Golf Course is currently irrigated with reclaimed wastewater. Grab water samples were collected from three (3) ponds located on the golf course over the course of a year and were analyzed for …

Tertiary Phosphorus Removal Hampton Roads Sanitation District (HRSD) Virginia Initiative Plant (VIP): Technology Selection and Operational Considerations
Excess phosphorus and nitrogen released in treated wastewater can harm rivers and coastal ecosystems by promoting algal blooms and reducing water quality. Beginning in 2032, the Hampton Roads Sanitation District (HRSD) must meet a much stricter limit for phosphorus in treated wastewater at its …

Metagenomic Data Analysis Using Extremely Randomized Tree Algorithm
… been detected in aquatic environments such as untreated and treated wastewater, river and surface water. ARG proliferation in the aquatic environment could depend upon various factors such as geospatial variations, the type of aquatic body, and the type of wastewater (untreated or treated) …

Investigación sobre reutilización de aguas residuales para fines urbanos (recreativos y limpieza viaria), con vistas a justificar una propuesta de normativa
… the process of biological treatment used in wastewater reclamation and the actual regulation about the several uses. It also emphasizes the treated wastewater use for recreative and public thoroughfare cleaning purposes, taking into account that in the year 2000 half of world population will …

Shallow water outfalls for brine disposal from desalination plants
… include heated water from thermal power plants, treated wastewater effluent from sewage treatment plants, and reject brine from desalination plants. At locations with shallow water depth, the interaction between adjacent jets is enhanced and can affect mixing. The mixing of submerged outfalls in …

Microbial and Chemical Affects on Leachate from Calcareous Soils Treated with Wastewater Effluent
… strain on water resources, prompting the use of treated wastewater effluent for irrigation in some areas, including the desert regions of the Western United States. To determine the potential effects of using secondary effluent for irrigation, we applied wastewater effluent and irrigation waters …

Fate and behaviour of drugs in the environment
… treatment works (STWs) are routes through which treated wastewater effluents often containing myriads of chemicals are passed into receiving waters due to incomplete removal processes as have been identified in several studies. The current work aimed to determine the levels of these chemicals in …

A Comparative Microbial Composition Assessment of Stormwater, Urban Runoff and Wastewater
… urban runoff (n = 96), stormwater (n = 8), and wastewater (n = 16). We quantified the densities and reductions of E. coli and Enterococcus, in raw stormwater, treated urban off from the Santa Monica Urban Runoff Recycling Facility (SMURRF) and wastewater from the Eastern Municipal Water …

Unveiling Causal Links, Temporal Patterns, and System-Level Dynamics of Freshwater Salinization Using Transit Time Distribution Theory
… (IPR) that augments critical water supplies with treated wastewater to enhance water security presents complexities in water quality management. This dissertation explores the complex interplay between FSS and IPR in the Occoquan Reservoir, an important drinking-water source in the Mid-Atlantic …

Assessment of a Passive Sampler for Aquifer Microbial Community Profiling and Comparison of Porous Media
Managed aquifer recharge (MAR) with advanced treated wastewater is a promising strategy to combat aquifer depletion; however, its impact on native microbial communities remains insufficiently characterized. Concerns include the potential introduction of pathogens, antibiotic resistance genes …

Assessment and characterization of dissolved organic nitrogen removal in simulated soil aquifer treatment systems
Treated wastewater (reclaimed water) is becoming more critical as an alternative water source due to population growth and extreme precipitation patterns. The more we rely on water reuse schemes, the more we have to expand our knowledge about the efficiency of treatment processes. As part of the …
