Enhancing Oil Separation. Improving Water Treatment. Maximizing Water Recovery.
Oil & gas operations generate complex water streams across exploration, drilling, production, separation, refining, and associated processing activities. Produced water, refinery wastewater, oily process streams, and contaminated utility water can contain varying concentrations of free and dispersed oil, hydrocarbons, suspended solids, dissolved contaminants, treatment chemicals, and other process-specific constituents. As water management requirements become more demanding, operators need technologies that can improve separation and treatment efficiency while supporting water reuse and reducing the overall environmental footprint.
Oil and gas facilities also operate under continuous pressure to reduce water consumption, improve produced-water treatment, minimize chemical and energy requirements, increase water recovery, and maintain reliable operation under highly variable feed conditions. The challenge becomes particularly significant when oil is present as fine dispersed droplets or stable emulsions, where conventional gravity separation and flotation processes can become less effective.
NanoCav® Nanobubble Technology by Prasinos addresses these challenges by enhancing the interaction between gas bubbles, oil droplets, suspended particles, and the surrounding water phase. The generation of fine nanobubbles provides a high interfacial area and greater opportunities for bubble–particle and bubble–oil interaction, supporting improved flotation and separation of suitable contaminants. The hydrodynamic cavitation environment also assists in breaking or destabilizing certain interfacial structures, creating more favourable conditions for subsequent separation and treatment. This makes NanoCav® relevant to applications including produced-water treatment, oily wastewater separation, refinery wastewater treatment, process-water recovery, and polishing of treated effluents. Depending on the water characteristics and treatment objective, the technology can be integrated into existing separation and treatment systems rather than requiring a completely independent treatment philosophy.
Enhanced Oil Separation – Supports flotation-based removal of suitable free and dispersed oil.
Fine Droplet Interaction – Provides greater bubble surface area for interaction with fine oil droplets and suspended contaminants.
Improved FOG & Solids Removal – Supports separation of suitable floatable contaminants before downstream treatment.
Reduced Downstream Loading – Effective upstream separation can reduce the contaminant burden on subsequent treatment stages.
Enhanced Biological Oxygen Transfer – Suitable configurations can improve oxygen availability in aerobic treatment systems.
Process-Water Recovery – Supports treatment strategies aimed at increasing opportunities for water reuse.
ETP Retrofit Capability – Can be integrated into existing treatment infrastructure where technically suitable.
Reduced Chemical Dependence – Provides a physical separation mechanism that can complement, rather than rely solely on, chemical treatment.
Scalable Process Configuration – Can be engineered for different flow rates, contaminant loads, and facility sizes.
