PWI Analysis
Sigma Waters: matching a process to the next use
Develops ozone-based systems for oilfield water treatment.
The directory does not yet document operating locations for this company. The company website is the starting point for confirming service coverage.
PWI perspective: A treatment offering is most useful when its starting water, target quality and operating conditions are clear. That is the basis for comparing technologies that may otherwise sound similar.
The question we would test for Sigma Waters: What feedwater was tested, what quality was achieved, and what were the cost and residuals per barrel?
