Abstract
A new water treatment system for SAGD operations is disclosed. Instead of treating both produced water and recycled water using warm lime softening systems, the recycled water is combined with saline water in a cold lime softening system. This results in slightly warmed reactions that require less chemicals during the lime softening process while also allowing for larger volumes of treated produced water to be generated by the warm lime softening system.
