Who We Are
Incorporated: 2011
Venture capital funding:
• Energy Ventures
• Harris & Harris Group
Osorb® Media - a
regenerable media which
removes, free, dispersed &
soluble hydrocarbons &
toxic contaminants from
oilfield water & gas streams.
PWA is to be the
internationally recognized
produced water treatment
solution provider of choice
within the oil and gas
industry.
The primary market for
Osorb is the treatment of
produced water to meet
discharge and reinjection
specifications.

Hydrocarbon Dew
Point Reduction
(HDPR) in natural gas
at client well site.
Capture of the liquid
and vapor-phase
heavier hydrocarbons in
the gas stream
HDP reduced from
58°F to -92°F @ 80 psi
and 80°F
Regeneration of
Osorb with heat and
gaseous purge
results in pure
hydrocarbon value
stream.
