Over the past decade, a diversity of emerging contaminants has been identified in waters around the globe. Of particular interest are pharmaceuticals and personal care products (PPCPs) and potential endocrine disrupting compounds (EDCs), both of which are generally detected in extremely low concentrations in water.

Oxidative Treatment of Organics in Membrane Concentrates

The use of membrane processes for wastewater treatment and reuse is rapidly expanding, especially the use of reverse osmosis (RO) membranes. RO membrane processes effectively remove organic, inorganic, and biological constituents, which accumulate in membrane concentrates. Therefore, membrane concentrates represent a significant concentrated point-source flow from the urban system into the environment.

Monitoring for Microconstituents in an Advanced Wastewater Treatment Facility and Modeling Discharge of Reclaimed Water

Advanced wastewater treatment (AWT), which includes filtration, carbon adsorption, phosphorus removal, and nitrogen removal, can effectively remove the majority of pollutants. However, the remaining microconstituents (including potential endocrine disrupting compounds, pharmaceuticals, and personal care products) in reclaimed water may raise public health and/or aquatic health concerns. Although certain microconstituents may persist following wastewater treatment, current research suggests that advanced treatment technologies can effectively remove them.

Low-Cost Treatment Technologies for Small-Scale Water Reclamation Plants

The shortage of freshwater is a severe problem for many areas of the world. Water reclamation and reuse provide promising opportunities to ease freshwater shortage problems. However, data and technical information for low-cost treatment technologies for small-scale water reuse projects are often unavailable, especially to communities with limited financial and technical resources in rural areas and in developing countries.

Leaching of Metals from Aquifer Soils during Infiltration of Low-Ionic-Strength Reclaimed Water

zdorsey@watereuse.org — Wed, 03 Feb 2010 12:52:52 -0500

This research project assesses the potential for metal leaching during surface infiltration operations using reverse osmosis (RO)-treated wastewater and evaluates strategies for mitigating risks associated with metal leaching. The report is intended to inform utilities of major water quality parameters that contribute to leaching of metals of public health concern and to suggest strategies that may be used to mitigate the associated risk.

The Psychology of Water Reclamation and Reuse

zdorsey@watereuse.org — Wed, 03 Feb 2010 12:49:34 -0500

The Psychology of Water Reclamation and Reuse identifies and explains research needs that will help the water reuse industry better understand the human response to water reclamation and reuse. Under this project, initial research into the human response to water reuse was also conducted and the findings are presented. The research focuses on attitudes, beliefs, choices and decisions and the multiple variables that influence them.

Evaluating Pricing Level and Structures to Support Reclaimed Water Systems

zdorsey@watereuse.org — Wed, 03 Feb 2010 12:45:32 -0500

This research study developed a Microsoft® Excel Model that is designed to allow utility staff, public officials, and stakeholders to assess the financial solvency of a reclaimed water program. This Model also serves as a mechanism for the organization of key documents required throughout the reclaimed water decision-making process.
