Deploying Intensified, Automated, Mobile, Operable, and Novel Designs "DIAMOND" For Treating Shale Gas Wastewater
Executive Summary
One of the key technology gaps identified in the RAPID roadmap was to develop design tools and practices that would reduce the need for non-recurring engineering design costs in modular applications. This project is focused on developing integrated design and operating approaches for modular systems that can be deployed in the treatment of flowback and produced water resulting from shale gas production. Because of the highly distributed nature and variable characteristics of shale-gas wastewater (SGWW), there is a unique opportunity to deploy modular systems. There is also a major challenge in developing tailored designs for each source of wastewater. An integrated theoretical-experimental project is being executed to: (1) Assess, screen and integrate commercially-viable conventional and emerging technologies for wastewater treatment, (2) Develop computer-aided modeling, design, operation, scheduling, and costing approaches for non-recurring engineering needed to deploy the SGWW treatment systems, and (3) Demonstrate proof-of-concept via applications to a broad range of SGWW samples. A combination of systems engineering approaches and experimental/pilot-scale work will be used to generate commercially viable design and operational strategies with significant impact.
Potential Impact
The majority of SGWW is disposed in underground injection control (UIC) wells. Development and application of novel treatment technologies to enable on-site water recycling and/or recovery for other applications is needed. These technologies will lead to a reduction in the overall cost, energy, and environmental impact for SGWW management.
