Nanobubble Technology for Oil & Gas – Canada Case Study

INTRODUCTION

Canada’s oil & gas industry - especially in Alberta and Saskatchewan - deals with complex water challenges:

1. High TSS
2. Emulsified oil
3. Surfactants from drilling fluids
4. Odour issues
5. High chemical treatment costs
6. Stringent environmental discharge regulations

A major upstream operator adopted NICO Nanobubbles to optimize its water treatment efficiency and reduce chemical dependency.

Challenges Before Implementation:

1. High Emulsified Oil Content.
2. High COD & BOD Loads.
3. Odour and H₂S Formation.
4. Sludge Accumulation in Equalization Tanks.
5. Excessive Chemical Usage.

NICO Nanobubble Integration

NICO deployed a custom NB-Series Oxygen & Ozone Nanobubble System with:

1. Continuous nanobubble infusion
2. Side-stream piping integration
3. No change to existing treatment tank
4. Automated flow-based operation

Results After Nanobubble Application

1. Faster Oil–Water Separation: Nanobubbles attached to oil particles, increasing buoyancy.
2. COD Reduction of 15–18%: Nanobubble oxidation pre-treated the water, lowering load on downstream processes.
3. Significant Odour & H₂S Reduction: Within 72 hours, odour dropped sharply and H₂S levels reduced due to oxygen-rich environment.
4. Lower Chemical Demand (20–30%): Coagulant and oxidizing agent usage reduced because nanobubbles provided natural oxidation.
5. Sludge Reduction & Improved Settling: Tank cleaning frequency dropped due to finer oxidation of solids.
6. Enhanced Environmental Compliance: Better water clarity and lower organics helped meet Canadian environmental discharge norms more reliably.

NICO Nanobubbles delivered a measurable improvement in oil & gas water treatment performance. The operator achieved lower chemical usage, better oil recovery, reduced odour, and improved downstream efficiency - all with a simple retrofit and low maintenance.

Nanobubble technology is proving to be a game-changing advancement for Canadian oil & gas operations.
