< Topic >Drawing up the water of blowhole mixture continually, the juvenile fish the blowhole symptom it does not emerge, it develops & it offers the water filtration equipment for clarifying which has the blowhole symptom prevention function which can obtain the raising seawater.SolutionsThe water (the seawater or the fresh water) in filtration equipment for clarifying 1, you draw up the water from underwater, X through intake pipe 2, you draw up with intake pump, 3 insert in arrival tank 4, through existing blowhole removal device than the said arrival tank 5, inflow into filtration equipment for clarifying itself 1, inside percolation treatment water chamber 1of a the said computer, you provide blowhole symptom Characteristic water perception device 6, measure the oxygen tonnage of the water, the inside of aforementioned percolation treatment chamber 1a becomes oversaturation and when it is the seawater or the fresh water where the blowhole is many, it halts filtered water supply, removing the blowhole with blowhole removal device 5It does, it removes the minute blowhole which is included in the water to the specified quantity, usually the water and it makes water mix which remove the particulate blowhole with blowhole removal device 5, the optimum water (with the seawater or the fresh water) with it does as raising water.< Choice figure >Drawing 1【課題】気泡混じりの水を連続的に汲み上げても稚仔魚が気泡症を発症せず、飼育海水を得ることの出来る気泡症防止機能を備えた水ろ過装置を開発・提供する。【解決手段】水(海水または淡水)ろ過装置1において、水中Xより水を汲み上げ、取水管2を介して、取水ポンプ3で汲み上げ、着水槽4に入れ、該着水槽より既存の気泡除去装置5を介してろ過装置本体1に流入させ、該本体のろ過処理水室1a内に、気泡症性水感知装置6を設け、水の酸素量を計測し、前記ろ過処理室1a内が過飽和となり気泡が多い海水または淡水の場合は、ろ過水供給を停止し、気泡除去装置5で気泡を除去し、水に含まれる微細気泡を所定量まで除去し、通常水と気泡除去装置5で微粒子気泡を除去した水とを混合させ、飼育水として最適な水(海水または淡水)とする。【選択図】図1
