3. OilPaq – Description
• Separation of suspended solids and free & emulsified oil in produced water for
beneficial re-use, heavy brines or re-injection in tight formations
• Acts as pre-treatment when combining with optional reverse osmosis (RO)
technology for achieving irrigation water quality (TDS of raw water is < 30,000 mg/l)
• Available as skid-based equipment
• Modular build allows for flexible increase / decrease of capacity
• Submerged ceramic plate ultrafiltration (UF) membranes, void size of 0.1 µm
• All necessary ancillary equipment contained within skid, i.e. pumps, PLC, piping,
process tanks, etc.
• 90% to 99% water recovery for Fit-To-Purpose reuse or possible irrigation. Waste
from treatment 1% – 10% of inflow
• Optimize all related future ESG compliances

4. OilPaq – Key Features
• Total Suspended Solids removal < 5.0 mg/l, typically < 2.0 mg/l
• Free and emulsified removal < 5.0 mg/l, typically < 2.0mg/l
• Chemical free bacteria elimination (SRB – Sulphur Reducing Bacteria / APB – Acid
Producing Bacteria)
• Submerged hydrophilic / oleophobic ceramic plate membranes with a negative
filtration pressure of 1.5 to 4.5 psi (vacuum)
• Flexible with changing loads in raw water
• Extracts free and emulsified oils from the raw water without altering the oil properties
• Low cost of operation thanks to low energy consumption (< $0.15 kWh/bbl or $0.007
kWh/gal)
• Virtually chemical free separation process (< 1.0 cent/bbl cost)
• Remote, automated smart device controlled. Minimal manpower operation. Several
OilPaq’s can be operated by a single technician
• Automatic cleaning of the membranes to manage clogging and fouling

5. Flat Sheet Membrane
Submerged Ceramic Flat Sheet Membranes

6. Flat Sheet Membrane vs. Cross-Flow Membrane
• Filtration vacuum on filtered water side
• High flux operation at very low pressure
• No compression of suspended solids
• Insensitive to high suspended solids loads
• Long dead end filtration period
• Low and short duration backwash
• Very high recovery rate
• Low power consumption
• Easy to clean

7. Flat Sheet Membrane vs. Cross-Flow Membrane
Cross-Flow Membrane
TMP range
15 to 60 psi
• Higher filtration pressure on feed side
• Compression of suspended solids layer
• Low membrane permeability leads to
higher fouling and low flux operation
• Limited to suspended solids loads –
risks of membrane blocking and clogging
(additional pre-treatment recommended
or frequent backwash)
• High feed pressure can lead to passing of
deformable contents and decrease
filtered water quality
• High power consumption
• Greater cleaning required

27. NanoPaq - PFAS / PFOS Removal From Ground Water
• NanoPaq combines field proven ceramic ultrafiltration (UF) membrane technology from
Maritime application with highly adsorbent material to eliminate even the short-chained
PFAS molecules from water
• Carbon-based adsorbent material has much higher loading potential than conventional
technologies like activated carbon and/or ion exchange resins
• Combining the above with reverse osmosis (RO) membranes allows a far smaller waste
volume than when using activated carbon or ion exchangers
• This leads to a significant reduction in operation costs compared
to existing mainstream technology to address PFAS / PFOS removal.
