Decision Support System for Selection of Satellite versus Regional Treatment for Reuse Systems
Date: December 31, 2009
The project developed the Decision Support System (DSS) tool, which provide a broadly applicable, standardized approach to evaluating satellite wastewater reclamation systems as an alternative to traditional regional wastewater reclamation facilities....
Collecting, Exploring and Interpreting Microbiological Data Associated with Reclaimed Water Systems
Date: December 31, 2009
The project developed a guidance manual to provide users with a context for collecting, exploring, and interpreting microbiological data associated with reclaimed water....
A Reconnaissance-Level Quantitative Comparison of Reclaimed Water, Surface Water and Groundwater
Date: December 31, 2009
The project provides insight into the occurrence and distribution of constituents that occur typically in very low concentrations, e.g., micrograms per liter or nanograms per liter, in reclaimed water, groundwater, and surface water....
Honolulu Membrane Bioreactor Pilot Study
Date: December 31, 2009
The project consisted of a side-by-side pilot demonstration of six different membrane bioreactor (MBR) systems at the Honolulu wastewater treatment plant (WWTP) in Ewa Beach, Hawaii, and a variety of activities, including bench- and pilot-scale tests, aeration testing, and a feasibility study....
Date: December 31, 2009
The project documents the water quality and cost trade-offs associated with storage options for the reclaimed water, considering the trade-offs involved in the treatment, management, and operating procedures at wastewater treatment facilities preceding discharge of the reclaimed water to the storage systems....
Date: December 31, 2009
The project developed a laboratory method for reliable quantification of hydrogen peroxide in the 0.5- to 5-mg/L concentration range that is effective in a natural water matrix as well as in the presence of combined chlorine (chloramine)....
Formation and Fate of Chlorination Byproducts in Desalination Systems
Date: December 31, 2009
The project assesses the occurrence of contaminants of concern in water produced by desalination systems. The project also considers the potential impacts of these contaminants on human health in desalinated water and on aquatic organisms in waters that receive desalination concentrate....
Development of Indicators and Surrogate for Chemical Contaminant
Date: December 31, 2008
The project identifies surrogate parameters and indicator compounds for wastewater-derived chemical contaminants that might be useful in the assessment of indirect potable reuse systems......
Impacts of Membrane Process Residuals on Wastewater Treatment
Date: December 31, 2008
The project provides practical guidance to utilities concerning the effects of membrane process residuals on wastewater treatment (including treatment processes, effluent quality, and water reuse and residuals management options)....
WateReuse is the only trade association that focuses solely on advancing laws, policy and funding to increase water reuse. Our niche strategy sets us apart from other organizations in the water industry.
