END?: Managing Energy and Scale Formation at High Recovery
Presented: 10/30/19
High recovery desalination is challenged by scale formation, energy consumption, and cost. The fundamentals of electrodialysis reversal make it uniquely suited to overcome membrane scaling at high recovery due its ability to pass silica through the system without concentrating and built-in membrane cleaning with polarity reversal for other scalant...
Overcoming the Challenges of High Recovery Operation with Electrochemical Desalination
Presented: 10/27/21
Water efficiency (recovery) for industrial process and wastewater treatment is often limited by hardness and silica levels in the feed stream. In particular, water efficiencies above 90% often lead to significant operational challenges for membrane desalination systems. This presentation will discuss the challenges presented by hardness and silic...
