Problems solved by technology
Air bubbles formed in fresh water produce air bubbles of such a size, see Figure 12, that the fry can confuse the air bubbles with the feed, which causes fry to possibly have higher mortality in water than in light conditions, temperatures suitable for fry, or to be eaten risk, or fry are not getting enough feed

Embodiment Construction
[0036] The protein skimmer according to the present invention is further described below with reference to the accompanying drawings.
[0037] Referring now to FIG. 1 , there is shown a simple aquaculture or mariculture setup with a container 2 for fresh or saltwater fish or other aquatic organisms, with a protein skimmer according to an alternative embodiment of the present invention. A discharge pipe 4 for water is provided from the container 2 to the pump 5, together with a return pipe 3 for water from the pump 5 to the container 2 for circulation of the water. Furthermore, in this embodiment a canister 1 is shown with a particle filter 7 which is arranged between the discharge line 4 from the container 2 and the return line 3 to the container 2 . On a substantially horizontal straight portion 90 of the return pipe 3 a side branch 9 is provided. The end or outlet 31 of the return pipe 3 is shown here arranged at an upward oblique angle relative to the horizontal main chann...

This invention relates to a protein skimmer for use in purification of water by culture of fish or orther water organisms in a reservoir, or aquarium (2) with a circulation system comprising one or more discharge tubes for water from the reservoir (2) to a pump (5) for circulation of the water, and a return tube (3) for water directly or indirectly from the pump (5) to the reservoir (2). The protein skimmer is characterized in that the return tube (3) comprises at least one generally horizontal, straight portion (90) having one or more upwardly directed side branches (9) which has an opening leading to air, in which the generally horizontal straight portion (90) is arranged for rapid passage of the water past the side branch (9) and to have the water level at or above the intersection of the side branch (9) with the straight portion (90), and in which the side branch (9) is directed rearward relative to the direction of the water flow in the straight portion (90), and forms a first angle (v) with between 0 DEG and about 90 DEG with the straight portion (90). During water flow a protein foam will be formed at the water surface at the intersection of the side branch (9) with the straight portion (90) of the return tube (3), and that the protein foam is allowed to grow upwardly from the water surface for discharge through the side branch (9). The return tube (3) is further arranged for having the entirely or partially purified water to flow further through the straight portion (90) and back directly or indirectly to the reservoir (2). The invention further relates to a process for purification of water by culture of fish or other organisms in a reservoir (2), by means of a protein skimmer.
Description
technical field [0001] The present invention relates to a separation device, also known as a deskimmer or skimmer, for removing protein from water in aquaculture installations and aquariums. In particular, the present invention relates to aquaculture installations for food fish, or in aquariums for relatively large numbers of ornamental fish such as koi or other freshwater fish, or in aquariums for other freshwater organisms such as crayfish. A protein skimmer that circulates the water in the tank. The protein skimmer according to the present invention can also be used to remove protein from seawater in a culture tank for marine organisms. Background technique [0002] One problem that the inventors have tried to solve with the present invention is to reduce the supply of air to the water during the purification process for removing proteins from the water. If air is supplied to the water in the form of compressed air or air bubbles, a large amount of nitrogen in the air w...
