filtration loss of headとは 意味・読み方・使い方

When filtration is terminated because of the increase in the loss of head (S14: YES), the pouring rate is kept as it is (S16) if the continued time of filtration T is equal to or longer than a specified period (S15: YES) while the pouring rate is decreased (S17) if the time T is shorter than the specified period (S15: NO).例文帳に追加

ろ過の打ち切りが損失水頭の上昇であった場合（Ｓ１４：ＹＥＳ）、そのときのろ過継続時間Ｔが所定以上（Ｓ１５：ＹＥＳ）であれば注入率を据え置き（Ｓ１６）、所定以下（Ｓ１５：ＮＯ）であれば注入率を低減する（Ｓ１７）。 - 特許庁

The amount of backwashing water is reduced by filling a filter with 0.2-100 cm of fine sand with an effective particle size of 0.02-0.2 mm as filter sand and performing filtration so that filtering loss head immediately before backwashing becomes a high pressure of 2-40 m without adding a flocculant.例文帳に追加

ろ過砂として０．０２〜０．２ｍｍの有効径からなる細砂を０．２〜１００ｃｍ充填し、凝集剤を入れないで、逆洗直前の、ろ過損失水頭を２〜４０ｍの高圧までろ過することにより逆洗水量を削減する。 - 特許庁
