Emulsification Emulsifies for far less, at far lower pressures
Resin manufacturer S had been using emulsification equipment, costing in excess of $200,000 and running at a pressure of 50 MPa. Following a thorough performance assessment, they replaced it with an OHR MIXER at a cost of just $3,800 and running at just 0.5 MPa.

Neutralization Eliminates rapid oscillations in pH in strongly acidic and alkaline solutions
Factory M had been using a tank for neutralization, but inadequate mixing was causing the pH to oscillate rapidly between acid and alkali, which required the repeated addition of neutralizer to control. Introducing OHR MIXERs entirely eliminated this issue and cut neutralizer (in this case caustic soda) usage by some 30%. See graph at right.

When the pH is almost neutral, it reacts sensitively to neutralizer, resulting in large, rapid pH fluctuations between acidic and alkaline. Because conventional equipment cannot adequately mix the neutralizer, far more is required than would otherwise be necessary.

Dispersion Uniformly disperses ultra-low concentrations in a single pass
Cooking oil manufacturer N uses OHR MIXERs in all of its plants to uniformly disperse additives at an ultra-low concentration of 3.0 ppm (parts per million) in a single pass.

Mixing Uniformly mixes chemicals into liquids
Chemical plant S uses OHR MIXERs to uniformly mix flocculant (here PAC, polyaluminum chloride) into wastewater. The realization of uniform mixing reduced flocculant usage by 50%.

Other uses:
  • Emulsification without high pressure emulsification equipment
  • Demulsification using strong shear forces
  • Diluting highly-concentrated liquids with a high degree of precision
  • Producing emulsified fuel
  • Instantaneous blending of biodiesel fuel with light oil
  • Uniformly dispersing trace additives (e.g. perfumes, mineral liquids)
  • Complete reaction of flocculants without a reaction tank
  • Dissolving low-solubility liquids in other liquids
  • Instantaneous coagulation of soymilk and bittern in the production of tofu
  • Uniformly mixing low-viscosity liquids such as fruit juice into high-viscosity liquids such as starch syrup

Micro-/nano-bubble generation, DAF, gas dissolution, etc.

DAF systems Greatly improves existing DAF systems
Paper mill N had been using a DAF system with a pressure tank to collect paper fibers for recycling, but had considerable difficulty owing to the poor quality of the microbubbles. After installing the OHR MIXER into the existing DAF system, microbubble quality improved markedly, allowing a much greater proportion of fibers to be recovered.
The treated water contained a large amount of paper fibers
Ozone treatment Far higher efficiency, with no need for an ozone destructor
Paper mill T adopted an OHR MIXER–based microbubble ozone treatment method in order to decolor5,000 m3/day of colored wastewater.
With ozone off-gas reduced to near zero, the ozone destructor was left uninstalled.
Initial costs — which would have been around $6 million with conventional methods — were two-thirds lower, at just $2 million.

Deoxygenation Greatly reduces N2 gas consumption and treatment time
Chemical plant H had been bubbling nitrogen gas into water to deoxygenate it as part of the manufacturing process, but this required inordinate amounts of nitrogen and as much as 90 minutes of treatment time. After introducing an OHR-based deoxygenation system, nitrogen gas consumption fell by 79% — equivalent to $19,200 annually.

Other uses:
  • Ozone treatment of large volumes of water without waste ozone decomposition equipment
  • Oxidation treatment of waste liquid from desulfurization, using O2 gas
  • Neutralization of alkaline wastewater with CO2
  • Producing oxygen-rich water for agriculture and aquaculture
  • Producing highly-carbonated beverages
  • Producing cream filled with microbubbles
  • Producing finely-perforated urethane sponges
  • Dissolved air flotation (DAF) without a pressure tank
  • Installing an OHR MIXER into an existing DAF system in order to greatly improve SS separation
  • Removing dissolved oxygen in liquids (e.g. wines, sakés, organic solvents) via the nitrogen substitution method
  • Cleaning using microbubbled water (e.g. rice, beans, machine parts)
  • Filling fuel oil with microbubbles in order to improve the fuel efficiency of boilers
  • Reduction reaction by generating micro-/nano-bubbles of H2
  • Producing microbubbled water for cooling (e.g. machine tools, iron manufacturing, cooling towers)

Mixing and Reaction
Disintegration and uniform dispersion

Disintegration Breaks up and redisperses intractable aggregates in slurry
Chemical plant M had been unable to disintegrate and redisperse agglomerated carbon powder in slurry. This carbon powder had agglomerated to around 5–10 mm in size. Various different agitators were tried but none proved capable, even with extensive treatment time.
The OHR MIXER was able to successfully disintegrate and redisperse these agglomerates exceptionally well in a single pass.
Disintegration and uniform dispersion
Dispersion and oxidization Oxidizes pigments while uniformly dispersing them into solvents
Chemical company D uses OHR MIXERs to oxidize pigments while uniformly dispersing them into solvents, both domestically and overseas.
Disintegration and uniform dispersion
Dispersion Uniformly disperses powder into oil
Food manufacturer R disperses vitamin C powder into cooking oil. Undispersed powder clogged the filters, which then required cleaning 5 to 8 times every day.
The newly-introduced OHR MIXERs made uniform fine dispersion possible, eliminating the need for filter cleaning and enabling the production line to run continuously.
Other uses:
  • Fine dispersion of various powders into liquid (e.g. vitamin C powder, flocculant powders)
  • Instantaneously dispersing oil-degrading bacteria into seawater following an oil spill
  • Fine dispersion of pigments in inks and paints
