Western Wyoming Case Study
In October, 2007, GeoPure Water Technologies, LLC ran a one-week
field test in western Wyoming for a major oil and gas operator using
its 20 gallons-per-minute portable test unit. The objective of the
test was to determine the fresh water recovery rate and operational
cost of handling produced water containing corrosion inhibitor,
alcohols and surfactants. These test data would then be used to
design a large scale treatment system.
The feed water was pretreated using a chemical
coagulation/flocculation process, and the resulting pretreated fluid
was then passed through the GeoPure membrane system. The system
successfully processed the feed water, as shown by the input and
output water chemistry comparison below:
