Recovering Filter Backwash to Reduce Groundwater Consumption

摘要

The filtration of groundwater through a multimedia filtration system is a critical step in extending the life of the 5 μm cartridge filters ahead of the RO system. Conducting a quick evaluation and analysis on the quality of the multimedia filter backwash stream at the selected Saudi Aramco facility showed that it is an easy-to-treat stream, of which a significant portion can potentially be recovered for reuse. This is in line with the Saudi Aramco's Water Conservation Policy to reduce groundwater consumption. Consequently, the involved parties established communication to explore and evaluate potential technologies to treat and reuse this valuable wastewater stream.
