SOLUTIONS FOR HIGH-TDS WATER REUSE

摘要

The Saudi Arabian Oil Company (Saudi Aramco) uses wastewater high in Total Dissolved Solids (TDS) as a resource to save precious groundwater. Reusingrnhigh-TDS water is a challenge and is often considered impossible for many reuse applications. This paper presents some of Saudi Aramco’s methods and lessonsrnlearned that make reusing high-TDS water possible.rnThe company owns and operates wastewater treatment and reuse facilitiesrnthroughout Saudi Arabia. These facilities reclaim approximately 20 millionrngallons of water per day with TDS ranging 1,800-3,500 mg/l. Reuse savesrngroundwater for many uses and avoids the high cost of seawater desalination.rnSaudi Aramco’s major reuse applications include: Golf Course Irrigation,rnLandscape Irrigation, Sod Farming, and Habitats for Migrating Birds.
