Hydrodynamic Cavitation Technology
Hydro Dynamics, Inc. (HDI) has developed a patented technology providing
breakthrough benefits for industrial processing of fluids. HDI’s product, the
ShockWave Power™ Reactor (SPR) utilizes "controlled cavitation” to solve critical
problems for customers in numerous industries.
The SPR represents a paradigm shift for fluid
processing and is truly a next generation
industrial technology that allows customers to
realize significant cost savings through improved
decreased maintenance costs and reduced
environmental impact. The SPR has been
installed all over the world and is used by several
Fortune 500 companies. HDI, founded in 1991, is
headquartered in Rome, Georgia, USA.
As a liquid passes through the SPR it is subjected to
“controlled cavitation”. The heart of the device is a
specially designed rotor that spins. The spinning action
generates hydrodynamic cavitation in the rotor cavities
away from the metal surfaces. The cavitation is
controlled and therefore there is no damage. As
microscopic cavitation bubbles are produced and
collapse, shockwaves are given off into the liquid which
can heat and/or mix.
• The heart of the technology is a specialized rotor
• The rotor has dead-ended cavities
• Spinning creates low pressure at the cavity bottoms
• The low pressure zones collapse releasing shockwaves
• Cavitation is created in the cavities, not on metal surfaces.
• The Cavitation is controlled, therefore there is no damage.
Alternative Energy : Increased alternative fuel usage is being fueled by
America’s need to be less dependent on foreign oil and new government
regulations. The SPR speeds up the reaction time and can allow for a
higher yield and higher production rate compared to conventional
technology while demonstrating significant increases in final product
Chemical Processing : The world’s industrial base relies on the
increased production of chemicals and the introduction of new
technologies to reduce costs and introduce new products.
Food and Beverage : Increased regulations, that insure food purity,
demand better safer ways to process food stuffs. Customers also demand
higher quality while the cost of raw ingredients continues to increas.
Refinery Services : The challenges for the Petroleum industry go beyond
discovery of new oil deposits. Refineries around the world are searching
for new technologies that will improve efficiencies and reduce
environmental hazards.
ShockWave Power Biodiesel Reactor
The SPR can process low-grade soy, poultry fat and beef tallow without
compromising results while producing tremendous savings. The SPR offers
numerous advantages over conventional technologies because it can run as a true
continuous process or in batch mode. To date we have sold 500 million gallons of
biodiesel reactor capacity.
The SPR provides the following benefits
• Lower monoglycerides
• Feedstock flexibility
• True continuous operation
• Potential to lower catalyst
• 1-150 million gallon/year systems
• Highest quality biodiesel
Product Line
The ShockWave Power Reactor (SPR) harnesses the shockwaves produced from
controlled cavitation, resulting in the superior mixing, scale free heating or
extraction. The SPR has an elegantly simple and robust design proven through years
of commercial operation in diverse industrial markets. The quality construction, easy
to use control system, small footprint and quiet operation make the SPR an
unparalleled reactor technology.

Research and Development
Higher surface refreshing in electrochemical or photon related
reactions can result in higher mass transfer. Any chemical
reaction that must occur on a surface could benefit from our
surface refreshing technology by improving the exposure, the
selectivity, and the yield by decreasing surface area
requirements, operational costs, capital costs and footprint
Our unique reactor design imparts five different mixing forces on the liquid at any
given point in the reactor. These extreme mixing forces increase the rate of surface
refreshing on the inner surface of the housing. The result is a concentration gradient
at the surface, which cycles the process chemicals for the treatment. This action
increases the mass transfer of photons in our UV-SPR and Electrons in our ElectroSPR.
At any fixed point on the inner housing surface, the refreshing rate may be as high as
several thousand times per second.
