OMR Boilers-The Problem

6. Conventional Membranes
Generation 1- Dynamic or Filter-cake
membranes
Generation 2- Fabricated and attached
skin layer membranes-Most common
Attached Skin Layer with pore size
0.01 to 0.1micron

7. The 3rd Generation-RSL Membranes
Patent protected
Membranes hang onto a
manifold and slide in and out of
the housing

8. Add a powder slurry of highly Ionic media to create
the Membrane skin layer
Skin layer on the tubes is approximately 50
microns- the thickness of hair
RSL Membranes
The Replaceable skin layer

9. Three Easy Operating Steps
1. Add the RSL Powder to the surface of the membrane
– 5 minutes
2. Filter the water to be treated-4 to 30 Hrs
3. When the pressure across the membrane reaches 10
psi (70kpa), the membrane tube is backwashed, the
powder is removed, and we start over with step 1- 2
minutes

10. The Highly Ionic Powder skin layer
simulates the DLVO Theory- What??
• River going into the
ocean full of suspended
solids.
• When river enters the
ocean, the solids
separate from the water
WHY? Because the high ionic environment in the
ocean (Na+ and Cl+) causes the electric double layer
around the solids to collapse.

11. Generation 1 –
Filtercake
(Dynamic
Membranes)

12. Generation 2 -
Conventional
and most
common
Membranes
(e.g.
Ultrafiltration
Membranes)

13. Phase 1 Filtration Cycle
Colloids repulsed from membrane surface
Pressure across the membrane is close to zero
Phase 2 Filtration Cycle
Colloids start to penetrate ionic powder skin layer
Pressure across the membrane rises to 70 kpa

14. Generation 3 –RSL Membranes
Phase 1
Phase 2
Phase 2

15. RSL Membranes selected as lead technology to treat Evaporator blow
down water and produced water from Canada’s oil sand operations
Completed fully commercialized RSL Membrane Project with
PetroChina– 25 m3/hr (3600 bbl/day)- operating 7days per week
and 24 hrs per day.
Proved RSL Membranes can separate oil and TSS simultaneously
from water.
Now in design for two more Produced Water Projects.
Commercialized Technology
“Petro China rates RSL Membranes as the
best technology in the world to treat
Produced Water”

16. 60000 bbl/day Produced Water-Permian Basin Case
RSL Membranes
Inside Trailer – RSL
Membranes™
Product 1- Treated water
ready for resale to Frac
operations, EOR, feed
water for irrigation
treatment
Product 2- Recovered oil
from the treated Produced
water

17. Produced Water Treatment
PWS Standards
Notes
1- Prime technology competitor to RSL Membranes is the DAF (Air flotation) Technology.
2- RSL Membranes provide very high quality treated water at 50% of DAF costs.
BROKER-DEALER/RIA USE ONLY

18. Conclusion-The 3rd Generation-
RSL Membranes
Patent protected
Provides 10 times the capacity and 90% less
energy.
Separates solids and oil simultaneously.
Replaces all existing processes that separate
solids (DAF’s, clarifiers, oil water separators,
sand filters & all low pressure membranes)
Very small footprint- easy mobility
