Long-Term Lab Scale Studies of Simulated Reclaimed Water Distribution: Effects of Disinfectants, Biofiltration, Temperature and Rig Design
As demand for alternative water sources intensifies, increased use of reclaimed water is important to help achieve water sustainability. In addition to treatment, the manner in which reclaimed water is distributed is a key consideration as it governs the water quality at the point of use. In this …

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 …

A Decision Support System for Indirect Potable Reuse Based on Integrated Modeling
Optimal operation of water reclamation facilities (WRFs) is critical for an indirect potable reuse (IPR) system, especially when the reclaimed water constitutes a major portion of the reservoir's safe yield. It requires timely and informed decision-making in response to the fluctuating operational …

Water Supply Planning for Landscape Irrigation in Virginia
A water supply plan approach was used to investigate irrigation application on landscaped areas in Virginia with a focus on turfgrass. The economically-important turfgrass industry in Virginia should be proactive in conserving drinking water supplies to meet human consumption needs, especially in …

Sorption and bioaccumulation of neutral and ionizable wastewater-derived contaminants of emerging concern: exposure of edible crops via solid and liquid effluent streams
… sorption tests with sludge solids from wastewater treatment systems examined sorption to the solid phase of CECs during wastewater treatment. Compounds, including neutral, acidic and basic CECs, were evaluated for how sorptive behavior might differ for CECs in different states of charge. …

Life Cycle Environmental Impacts and Decarbonisation Pathways of China’s Urban Water Systems
Urban water systems (UWSs) in China form an energy-intensive and intricate socio-technical network that links multiple components from water abstraction to sewage sludge disposal. As the country moves toward carbon neutrality, improving the environmental performance of the UWS has become essential. …

TEMPORAL DYNAMICS, ANTIMICROBIAL RESISTANCE AND PHYLOGENETIC RELATIONSHIPS OF BACTERIAL TAXA IN IRRIGATION WATER SOURCES AND RELEVANCE TO FOOD SAFETY
As climate change continues to stress freshwater resources, we have a pressing need to identify alternative (nontraditional) sources of microbially safe water for irrigation of fresh produce. Unfortunately, open water sources are often contaminated with many known human pathogens such as E. coli, …

Growth Media and Lipid Determination Comparison of High Rate Algae Ponds
… production relies on the use of a non-potable water source. Municipal wastewater is nutrient-rich and a cost effective option as a growth media in algae ponds. However, this resource may be too valuable for algal biomass production, as reclaimed wastewater is needed for surface irrigation and …
