This presentation introduced the results of research regarding water recovery from silica-saturated RO concentrate. Our results indicated that we can get up to 85% of the water back from the concentrate by using a seawater RO system with appropriate pH control and antiscalant addition. This information is of significance to water plant operators be...

Reverse osmosis concentrate volume reduction scenarios and associated challenges for inland desalting plants. Economic evaluation in cost vs. recovery. Zero liquid discharge (ZLD) discussion....

One of the largest uses of water in the United States and the world is for cooling systems in power generation. Closed-cycle cooling towers produce a concentrated water stream (called blowdown) that is similar to the concentrate from a reverse osmosis system. This project was directed toward cost-effectively recovering 70% to 90 persent of the wate...
