• Tiny crude droplets
• Emulsion mechanisms
(interfacial film, etc.)
• Prevent coalescing
• Produced water is
cavitated.
• Mechanisms are broken
down
• Crude coalesces
• Phase separation

Bacteria Colonies
• Protective Shell
Biocide injection
• Poorly Dispersed
Cavitek:
• Break down protective shells,
• Disperse bacteria & biocide,
• Disrupt cell membranes, and
• Biocide / Bacteria contact
Cavitek:
• High Level Immediate Kill
• Deep reservoir kill
• Long term kill/control

How cavitation treats bacteria.
Bacteria
Biocide Treatment should be preceded with:
• DNA qPCR assessment (microbial type & load).
• ATP assessment (microbial activity).
• Bactericide Selection Assessment.

“Overall, it can be said that use of cavitation in combination with conventional chemical methods
is far more suitable as compared to individual operations. It not only results in substantially lower
treatment times but also reduces the requirement of the chemicals under optimized conditions.”
Understanding Hydrodynamic Cavitation Report, I.B.Ignatius, S.A.Sagar, Birla Institute of
Technology, July 2016
“Cavitational reactors are more energy efficient as compared to the conventional techniques based
on the use of mechanical energy.”
Chapter 3: Cavitation Generation and Usage Without Ultrasound: Hydrodynamic Cavitation,
P.R.Gogate, A.B.Pandit, Mumbai Institute of Chemical Technology, Chemical Engineering
Department, 2011
Cavitek – Academic White Papers
“It can be said that the hydrodynamic cavitation reactors oﬀer immediate and realistic potential
for industrial scale applications as compared to the sonochemical reactors and the scale up of these
reactors is comparatively easier as vast amount of infor‐mation about the fluid dynamics
downstream of the constriction is readily available and the operating eﬃ‐ciency of the circulating
pumps which is the only energy dissipating device in the system is always higher at large scales of
operation.”
A review and assessment of hydrodynamic cavitation as a technology for the future, P.R.Gogate,
