Mr.Matsunaga of OK engineering Co.,Ltd. is researching since
1998 on fine bubble and has invented a loop flow method of Fine Bubble
Generator which can generate very efficiently micro and nano
sized bubbles. This OK Brand Fine Bubble Generator is patented by
Japan Patent Office <certificate of patent>.
High efficiency of OK Brand Fine Bubble Generators can enrich dissolved
oxygen and purify the polluted water very efficiently so that you can save
the working time and operating costs.
Fine Bubbles are classified into Micro & Nano by its size
Size of micro bubbles are approximately less than 50สm
Micro sized bubbles can stay long time in the water and rise very slowly
about 3mm in a minute
Micro bubbles take negative electrostatic charge,so don't absorb each other
Micro bubbles are transformed into nano bubbles in a certain condition.
Aeration Bubbles are expand and rise relatively fast toward the liguid
surface, and they are scattered into the atomosphere.
Micro sized Fine Bubbles float long time in the water after diffusing and
keeping balance internal pressure and surface tension,but finally melt
into the water and disappear.
Size of Fine Bubbles are approximately less than 20 microns diameter and
they receive the strong surface tension as gas-liquid interface area being
large in spite of small bubble volume. They are not crushed soon because
their internal pressure is also high,but some are crushed by pressure and
friction over the limit in the end.
Inside of bubble just before breaking is in the ultra-high heat and ultra-high-temperature
state that generate free radicals when they break. This nano sized bubble
is called Ultra Fine Bubble.
Definition of Fine bubble
Bubbles smaller than 100 สm diameter are called Fine Bubble and defined
1-100 สm diameter bubbles as
Micro Bubble,smaller than 1 สm diameter bubbles as Ultra Fine Bubble.

News: The fine bubble breakthrough
Our patented Loop Flow Method can generate nano bubbles efficiently
LM 20 of Nanosight Ltd.(UK) measured 480 millions/ml(mean:155 nm) nano
bubbles that generated by our
Loop Flow Method nozzle in 2012. Now we use our own measuring instrument
SHIMADZU SALD-7500nano
in order to measure nano bubbles constantly and get the similar result.

Fine Bubbles can supply and enrich dissolved oxygen in water so that can
accelerate growth of vegetables and bring a high yield.
Fine Bubbles can also enhance the srerilizing effect in water.
Characteristics of vegetables grown by fine bubbles are large,lush
and tasty.
Fine Bubbles can supply and enrich dissolved oxygen in water so that can
purify and sterilize the water efficiently.
Fine Bubbles can grow healthy fishes faster to use less fish feed and drug of the nursery.
Fine Bubbles can save the working time and operating costs.
Fine Bubbles can enrich dissolved oxygen in water efficiently and stay
durably so that activate aerobic biological treatment better.
Fine Bubbles take negative electrostatic charge and absorb positively electrostatic
charged pollutants in water and remove it
in order to do floatation separation efficiently.
Fine Bubbles are generated simply without a heavy equipment and make high
effect efficiently so that you can save the working time and operating costs of the wastewater treatment.
Water Purification (innovative Japanese Zoo)
Water of a hippopotamus aquarium is being purified by OK Brand Fine Bubble
diffusers,so that people can clearly observe aquatic activity of the hippopotamus
in the water.
8 sets of OK Brand 100L/min Nozzles are used in this aquarium.
