Backwashing (water treatment)とは 意味・読み方・使い方

To provide a method for backwashing a filter treatment means that can supply clear treated water to a rear-stage reverse osmosis membrane treatment means and efficiently backwashes a hardly blocked and inexpensive filter treatment means and a water treatment apparatus therefor.例文帳に追加

後段の逆浸透膜処理手段に清澄な処理水を供給でき且つ閉塞し難く安価な濾過処理手段を効率よく逆洗する濾過処理手段の逆洗方法及び水処理装置を提供する。 - 特許庁

To provide a filtration method which can reduce the turbidity of treatment water enough and the amounts of backwash water to be used for the backwashing of a filtration means and backwashing wastewater to be discharged when suspended solids in raw water are removed and an apparatus for the method.例文帳に追加

原水中の懸濁物を除去するに際し、処理水の濁度を十分に低減すると共に、ろ過手段の逆洗に用いる逆洗水及び排出される逆洗排水の量を十分に低減することが可能なろ過装置及び方法を提供すること - 特許庁

To provide a water treatment apparatus for frequently backwashing a filter element to always operate the same normally and sufficiently cleaning water to be treated to obtain product water of excellent quality.例文帳に追加

濾過要素が頻繁に逆洗され常時正常に働き、被処理水が十分に清浄化されて、優れた品質の生産水が得られ水処理装置を提供する。 - 特許庁

When a large quantity of wastewater flows in the receiving chamber 10 suddenly and the water levels of the first and second cleaning treatment chambers 11, 12 are raised suddenly, the water in the second cleaning treatment chamber 12 flows out to the treated water chamber through a backwashing water supply pipe 31.例文帳に追加

突発的に多量の排水が受入室１０に流入し、第１及び第２浄化処理室１１，１２の水位が急激に上昇してきた場合、第２浄化処理室１２内の水が逆洗水供給管３１も通って処理水室１３へ流出する。 - 特許庁

Since the level of the upper end of the partition wall 3b separating the first cleaning treatment chamber 11 and the treated water chamber 13 is higher than the level of the upper end of the backwashing water supply pipe 31, the water in the first cleaning treatment chamber 11 is prevented from overflowing the partition wall 3b to flow in the treated water chamber 13 in a short-circuited manner.例文帳に追加

第１浄化処理室１１と処理水室１３とを隔てる隔壁３ｂの上端のレベルは逆洗水供給管３１の上端のレベルよりも高位となっているので、第１浄化処理室１１内の水が隔壁３ｂを溢流して短絡的に処理水室１３に流入することはない。 - 特許庁

Only a necessary amount of backwashing water is circulated to a solid treatment apparatus in the high- degree cleaning of sewage wastewater or domestic wastewater wherein biological treatment method and a flocculation and sedimentation treatment method is used jointly to perform rational and efficient operation to reduce treatment cost.例文帳に追加

生物的処理や凝集沈殿処理法を併用している下水排水や生活排水の高度浄化において、必要量の逆洗水のみを固形物処理装置に循環させ、合理的、効率的な操業を実施することにより、処理コスト低減が可能である。 - 特許庁

To provide a filter apparatus capable of being achieved in miniaturization and wt. reduction and capable of performing effective backwashing treatment by utilizing high water pressure.例文帳に追加

逆洗処理を行える濾過装置であって、装置の小型化及び軽量化を図ることができ、しかも、高い水圧を利用した効果的な逆洗処理を行うことができる濾過装置を提供する。 - 特許庁

To suppress membrane fouling and to reduce not only the number of times of washing using chemicals but also equipment and a maintenance cost, in a water treatment method of a total amount filtering system including a membrane filtering process and a membrane module backwashing process.例文帳に追加

膜ろ過工程と膜モジュールの逆洗工程とを含む全量ろ過方式の水処理方法において、膜ファウリングを抑制し、ひいては薬品洗浄回数の低減と設備およびメンテナンスコストの低減を図る。 - 特許庁
