Title:
WHITEWATER RECOVERY PROCESS
Document Type and Number:
WIPO Patent Application WO/2014/094003
Kind Code:
A3
Abstract:
Whitewater recovery processes, and associated systems and components, are generally described. Certain embodiments relate to Whitewater recovery processes in which ion exchange is used to remove dissolved ions from the Whitewater, which can reduce the degree to which chemical additives are used in the process. In certain embodiments, flocculation and/or filter components can be employed to aid in the removal of suspended solids from the Whitewater.
