Title (EN) FILTER CARTRIDGE AND FILTER
(FR) CARTOUCHE DE FILTRE ET FILTRE
(JA) フィルターカートリッジ及びフィルター
Abstract:
(EN) The filter cartridge according to the present invention has a plurality of types of filtration base fabrics wrapped around a hollow inner cylinder or laminated. The filtration base fabrics are nonwoven fabrics in which a metal-adsorbing group is chemically bonded to a polyolefin fiber, and include a nonwoven fabric layer (A) 17a disposed on the downstream side and a nonwoven fabric layer (B) 17b disposed on the upstream side. The nonwoven fabric layer A is constituted by a polyolefin fiber chemically bonded with a sulfonic acid group as a metal-adsorbing group. The nonwoven fabric layer B is constituted by a polyolefin fiber chemically bonded with at least one group selected from an amino group, an N-methyl-D-glucamine group, an iminodiacetic acid group, an iminodiethanol group, an amidoxime group, a phosphate group, a carboxylic acid group, and an ethylenediaminetriacetic acid group, as a metal-adsorbing group. A filter cartridge and a filter that exhibit high efficiency in the adsorption and removal of metals are thereby provided.
(FR) L'invention concerne une cartouche de filtre qui comporte une pluralité de types de tissus de base de filtration enroulés autour d'un cylindre interne creux ou stratifié. Les tissus de base de filtration sont des tissus non tissés dans lesquels un groupe adsorbant les métaux est chimiquement lié à une fibre de polyoléfine, et comprennent une couche de tissu non tissé (A) (17a) disposée sur le côté aval et une couche de tissu non tissé (B) (17b) disposée sur le côté amont. La couche de tissu non tissé (A) est constituée d'une fibre de polyoléfine liée chimiquement à un groupe acide sulfonique en tant que groupe d'adsorption des métaux. La couche de tissu non tissé (B) est constituée d'une fibre de polyoléfine liée chimiquement à au moins un groupe choisi parmi un groupe amino, un groupe N-méthyl-D-glucamine, un groupe acide iminodiacétique, un groupe iminodiéthanol, un groupe amidoxime, un groupe phosphate, un groupe acide carboxylique et un groupe acide éthylènediaminetriacétique, en tant que groupe adsorbant les métaux. Il est ainsi obtenu une cartouche de filtre et un filtre qui présentent une efficacité élevée dans l'adsorption et l'élimination de métaux.
(JA) 複数種類の濾過用基布を積層又は中空状内筒に巻き付けたフィルターカートリッジであって、濾過用基布はポリオレフィン繊維に金属吸着基を化学結合した不織布であり、下流側に位置する不織布層(A)17a及び上流側に位置する不織布層(B)17bを含み、不織布層Aは金属吸着基としてスルホン酸基を化学結合したポリオレフィン繊維で構成され、不織布層Bは金属吸着基としてアミノ基、N-メチル-D‐グルカミン基、イミノ二酢酸基(イミノジ酢酸基)、イミノジエタノール基、アミドキシム基、リン酸基、カルボン酸基及びエチレンジアミン三酢酸基から選択される少なくとも一種を化学結合したポリオレフィン繊維で構成される。これにより、金属の吸着除去効率が高いフィルターカートリッジ及びフィルターを提供する。
