WRF issues four new RFPs

The WateReuse Research Foundation has issued four requests for proposals (RFPs) under its Solicited Research Program and Feasibility Studies Program. Contractors are selected through a competitive process.

The RFPs are for:

The Future of Purple Pipes: Exploring the Best Use of Non-Potable Recycled Water in Diversified Urban Water Systems – WateReuse-10-14
The objective of this study is to explore the future of purple pipe (non-potable recycled water) in the next 10-20 years. The proposed work will assess the future of purple pipe (non-potable recycled water supplies) reticulation (distribution systems) in the US and Australia in the context of increasingly complex, diverse and pressured water supplies.
Proposals by 12 January 2011.

Guidance for Selection of Selective Salt, Metal, Radionuclide, and Other Valuable Material Recovery Approaches – WateReuse-10-09
Selective compound removal may be an important consideration in the path to sustainable concentrate management through waste minimization. Patents exist for selective removal of particular components from a wide variety of waters, yet the feasibility of selective removal and marketing of products is not obvious. The objective of this study is to examine selective recovery and the experiences of a variety of industries with the goal of recovering valuable compounds from desalination concentrate streams.
Proposals by 24 January 2011.

Review of Nanomaterial Research and Relevance for Water Reuse – WateReuse-10-13
Nanomaterials are the subject of numerous ongoing research projects by various agencies and universities. The objective of this study is to gain a better understanding of the current nanomaterial research and relevance to water reuse. This study will provide a summary of the ongoing research and assess the need for additional research of nanomaterials related to recycled water.
Proposals by 12 January 2011.

Role of Retention Time in the Environmental Buffer of Indirect Potable Reuse Projects – WateReuse -10-05
The environmental buffer is a key element of the multi-barrier concept in indirect potable reuse through managed aquifer recharge. The objective of this project is to evaluate the role of retention time as the environmental buffer in managed aquifer recharge systems to achieve removal of pathogens, organic carbon, constituents of emerging concern and nitrogen in reclaimed water.
Proposals by 24 January 2011.
