granular bed filtrationとは 意味・読み方・使い方

To provide a structure for preventing the bridge of granular filter media in moving bed type upflow filtration equipment, which easily enables the prevention of the generation of bridge of the granular filter media such as sand causing the deterioration of filtration performance disabling to continue the operation and the breaking of the generated bridge in the moving bed type upflow filtration equipment.例文帳に追加

移床式上向流濾過装置において濾過性能が劣化し、運転ができなくなるような砂等の濾粒材のブリッジ発生の防止及び発生したブリッジの破壊が容易にできる移床式上向流濾過装置の濾粒材ブリッジ防止機構を提供すること。 - 特許庁

To provide moving bed upflow type filtration equipment free from discrepancy that sand is overflown from a cleaning water discharge box in a granular filter media cleaning structure of a float type blocking body for closing a discharge port for the granular filter media by the floating force is left underwater as it is.例文帳に追加

濾粒材洗浄機構の洗浄排水ボックスから砂がオーバーフローしたり、濾粒材排出口を浮上力で閉鎖するフロート式閉塞体が沈んだままとなるという不具合のない移床式上向流濾過装置を提供すること。 - 特許庁

This bottom bed sand for ornamental plant comprises a granular sintered compact consisting essentially of trass, is based on such a bond strength as to make a granular bond state collapse when the sintered compact is made into 1.0 cm thickness and ≥2.5 kg/cm2 pressure is applied to the sintered compact and makes excellent filtration action of water compatible with growth of plant.例文帳に追加

火山灰土を主成分とする粒状の焼結物を含有し、当該焼結物につき、１．０ｃｍの厚さとした場合に、２．５ｋｇ重／ｃｍ^2以上の圧力を加えた場合、粒状の結合状態が崩壊する程度の結合力であることに基づき、良好な水の濾過作用及び植物の育成とを両立し得る観賞植物育成用底床砂。 - 特許庁
