Definitions

  • Method and apparatus providing ultrasonic waves for enhancing the quality of water for aquatic animal and plant life.
  • the present invention relates to a method and apparatus for enhancing the quality of water for aquatic animal and plant life, e. g. for use in the rearing or cultivation of fish, seaweed, shellfish and other aquatic animals and plants under natural conditions or in water tanks.
  • An object of the present invention is to overcome the above described disadvantages and to provide a method and apparatus for enhancing the quality of water for aquatic animal and plant life, which makes it possible not to use chemials or pharmaceuticals at all, or to keep their use to a minimum, so that the quality of the water may be kept excellent over a long period of time.
  • the invention provides a method of enhancing the quality of water for aquatic animal and plant life, characterised in that ultrasonic waves are produced in the water.
  • the invention also provides apparatus for enhancing the quality of water for aquatic animal and plant life comprising a container for the water and means for producing ultrasonic waves in the water.
  • air bubbles with a diameter of 0.2 - 2.0mm are fed into the water and ultrasonic waves are produced by the collapse of the air bubbles.
  • the ultrasonic waves are produced directly by using one or more oscillators.
  • a layer of porous ceramic granules is provided in the water, and/or the water is circulated through a filter filled with porous ceramic granules. Furthermore, air may be fed between the porous ceramic granules in this filter.
  • ultrasonic waves By producing ultrasonic waves in the water, it is possible to preserve an excellent water quality over a long period of time by means of the cleansing action and sterilising action of the ultrasonic waves.
  • bacteria are produced naturally in the porous ceramic granules spread at the bottom of the water and/or in the porous ceramic granules in the filter, the water is cleansed by these bacteria digesting the excess ammonia, excreta, foodstuff and other contamination in the water etc.
  • the activity of the bacteria may be made still more vigorous by passing air through the porous ceramic granules in the filter and the cleansing action is thereby promoted.
  • Figure 1 is a diagrammatic vertical section of apparatus in accordance with the invention having a device for producing small bubbles
  • Figure 2 is a diagrammatic vertical section of part of apparatus in accordance with the invention having an ultrasonic oscilltor.
  • a device for producing small bubbles 2 is connected to a water tank 1 for rearing fish via an aperture 3 in the side of the tank 1.
  • the device 2 produces minute air bubbles 4 of diameter 0.2 - 2.0mm and these are fed into the tank 1 via aperture 3 together with water.
  • the air bubbles 4 fed into the tank 1 strike an object (e.g. a fish, net 10, a partition, etc. ) and collapse. When air bubbles of this size collapse, ultrasonic waves are formed, which produce a cleansing and sterilising action.
  • the device 2 need not operate continuously. A sufficient cleansing and sterilising effect is obtained if device 2 operates intermittently depending on the volume of the tank 1 and the type, number etc. of the fish being reared (e.g. 5 - 20 minutes per day).
  • Porous ceramic granules 5 mixed with pebbles, sand etc. are spread on the bottom of the tank 1. Bacteria are produced by the presence of water in the porous ceramic granules 5. These bacteria digest and decompose the ammonia, excreta, excess foodstuff, water contamination etc. in the tank 1, and the water is thereby cleansed. The bacteria are produced naturally in the porous ceramic granules 5 both in freshwater and in sea water.
  • the water in the tank 1 is fed, e. g. by means of a pump (not shown), to a filter 7 via a conduit 6 connected to the bottom of the tank 1, and is returned to the tank 1 after passing through the filter 7.
  • the interior of the filter 7 is filled with porous ceramic granules 8. Bacteria are produced in the granules 8 by the water passing there through, and these bacteria purify the water by digesting and decomposing the ammonia, excreta, excess food and water contamination etc. contained in the water passing through the filter 7.
  • a plurality of holes 9 for regenerative air are provided in the bottom of filter 7. Regenerative air fed into the filter 7 via the holes 9 increase the activity of the bacteria and thereby promote the cleansing action.
  • a plurality of ultrasonic oscillators 12 are arranged at suitable intervals on a support frame 11, which is fixed to the edge of the tank 1.
  • the oscillators 12 are driven electromagnetically and produce ultrasonic waves directly in the water.
  • the cleansing and sterilising action produced by the ultrasonic waves is just the same as in the case of the embodiment shown in Figure 1. If porous ceramic granules are provided at the bottom of the water and/or a filter filled with porous ceramic granules is provided, the cleansing effect on the water is further increased by the activity of the bacteria produced in the porous ceramic granules.
  • the method of controlling the quality of water used for aquatic animal and plant rearing and culture in the present invention is not limited to the case of a water tank. It may also be used in natural surroundings, such as the sea, lakes, rivers, etc. Furthermore it is not limited to fish rearing; it may also be used for the rearing or cultivation of seaweed, shellfish and other aquatic animals and plants.

Abstract

On améliore la qualité de l'eau pour les animaux et les plantes aquatiques en produisant des ultrasons dans l'eau. Ceci peut s'effectuer au moyen d'un dispositif (2) produisant des bulles (4) d'un diamètre de 0,2 - 2,0 mm, les ultrasons se produisant à la fin des bulles (4). Dans une variante, les ultrasons peuvent être produits par un ou plusieurs oscillateurs à ultrasons (12). De préférence, une couche de grains de céramique poreuse (15) est disposée au fond du réservoir (1) pour produire des bactéries de nettoyage. Dans une variante ou en plus, on fait passer l'eau par un filtre (7) contenant des grains de céramique poreuse (8), par lequel est amené, via des trous (9), de l'air régénératif.
