What is a micro-bubble generator, "eco-Bubble®" ?


Micro-bubble generator "eco-Bubble®-400" is made up of a water pump and a nozzle that creates micro-bubbles with a rotational flow of the water and air taken from the outside. The power consump-
tion of this device is only 400W, but it can produce a large amount of micro-bubbles from the nozzle with DDHRS.
  eco-Bubble®-400 can dissolve oxygen gas in the water quickly through the release of micro-bubbles with a diameter of less than 40 µm, and
exhibit an extremely high potential for controlling DO levels of the water.

 Important remarks: For the international order, we provide only the nozzle of eco-
  Bubble®-400. The customers need to purchase a water pump (400W of power
  consumption, 10 m of head of fluid, 50 L/min. of capacity) in their own country.

  • Design and speciations will be modified as the occasion demands.

eco-Bubble®-N series

eco-Bubble®-1N, -3N, and -5N are equipped with a single set of DDHRS type of nozzle,
or three or five sets of the nozzles, respectively. This device works by water supply from a small pump (400W for 1N model, 1500W for 3N and 5N model), and enables the release of a large amount of micro-bubble from these nozzles. Their potentials for oxygen gas dissolution to the water is enhanced as the number of nozzle.

(use of the device)

  • These models enable to dissolve water-soluble gases such as oxygen, carbon dioxide, etc., very efficiently to a large amount of water. They will exhibit a great performance for controlling DO levels of the water in aquaculture, enhancing oxidation in the process of water treatment, pH control of the water with carbon dioxide gas, etc.
