Title (EN) PROCESS FOR DEWATERING SLURRY
(FR) PROCÉDÉ DE DÉSHYDRATATION DES BOUES
(JA) スラリーの脱水方法
Abstract: front page image
(EN)Provided is a process for simply improving the handleability of a thixotropic slurry in transportation and so on. A process for dewatering a slurry which has a thixotropic region, including a step of dewatering the slurry by pressure filtration to a water content lower than that at the lowest flow value.
(FR)Le procédé ci-décrit a pour simple but d'améliorer la maniabilité d'une boue thixotrope au cours de son transport et ainsi de suite, ledit procédé de déshydratation d'une boue comportant une région thixotrope comprenant une étape de déshydratation de la boue par filtration sous pression jusqu'à obtention d'une teneur en eau plus basse que celle obtenue à la valeur d'écoulement la plus basse.
(JA) チクソトロピー性を示すスラリーに対する輸送等の取り扱い性を簡便に向上させる方法を提供する。チクソトロピー性領域を有するスラリーの脱水方法であって、当該スラリーを加圧濾過により、フロー値が最下点となる含水率よりも少ない含水率に脱水する工程を含む方法。
