About

Expand the utility-of the Solar Energy Desalination Analysis Tool (SEDAT) which was developed at the CLCA with data and process models needed to assist corporations in becoming water neutral by 2030. The software will enable cost-parity comparisons of water production via sustainable water desalination (on various sources and process technologies) with utility water rates and with other alternatives for producing water in select locations. The scope of work during 2023 will focus on US Brackish Water resource data GIS mapping and incorporating into SEDAT a model of Osmotically Assisted Reverse Osmosis (OARO) Desalination. and a model of Crystallizer for zero liquid discharge (ZLD) desalination of brackish water. Furthermore, Columbia will modify the SEDAT input/output data structure so that it can be migrated onto the cloud by WaterDAO.

Timeline

Task 1

Detail and quantify sources of brackish water by county by combining US Hydrologic Unit Code Unit (HUC) watershed classification data and USGS well (point) data on depth, TDS, and well yield and compile a database of brackish water salinity, depth and estimated resource for each county of the US.

Task 2

Develop, test and incorporate an OARO and a Crystallizer model into SEDAT.

Task 3

Modify SEDAT so that it can be migrated onto the cloud. Columbia will support WaterDAO in setting SEDAT on the cloud and WaterDAO will migrate, host and maintain it there. The software will remain Open Access.

Task 4 (June 30, 2023)

Detail current water price structures by utility and combine these with data from corporations available via the WaterDAO network. Mapping those on ArcGIS. Introduce “water neutrality” cost and credit algorithms to compare desalination with other water supply alternatives available to corporations.

Task 5 (December 2023)

Results Dissemination via a conference presentation
