Abstract:
(EN) Provided is a method for treating nonionic surfactant-containing water, the method comprising an adsorption step for passing nonionic surfactant-containing water as supplied water through a microfiltration membrane or ultrafiltration membrane, to obtain the filtrate having a reduced nonionic surfactant concentration as treated water, and a desorption step for bringing at least one of an alkali agent, an anionic surfactant, and an oxidizing agent into contact with the microfiltration membrane or ultrafiltration membrane, to desorb the nonionic surfactant adsorbed by the filtration membrane. Also provided is a water treatment method comprising subjecting the treated water to a permeable membrane treatment.
(FR) L'invention concerne un procédé de traitement d'eau contenant un tensioactif non ionique, le procédé comprenant une étape d'adsorption permettant de faire passer de l'eau contenant un tensioactif non ionique en tant qu'eau fournie à travers une membrane de microfiltration ou une membrane d'ultrafiltration, pour obtenir le filtrat ayant une concentration de tensioactif non ionique réduite en tant qu'eau traitée, et une étape de désorption permettant d'amener au moins l'un d'un agent alcalin, d'un tensioactif anionique et d'un agent oxydant en contact avec la membrane de microfiltration ou la membrane d'ultrafiltration, pour désorber le tensioactif non ionique adsorbé par la membrane de filtration. L'invention concerne également un procédé de traitement de l'eau consistant à soumettre l'eau traitée à un traitement de membrane perméable.
(JA) ノニオン界面活性剤を含む水を供給水として、精密濾過膜又は限外濾過膜に透過させ、ノニオン界面活性剤の濃度が減少した透過水を処理水として得る吸着工程と、アルカリ剤、アニオン界面活性剤、及び酸化剤の少なくとも一つを、該精密濾過膜又は限外濾過膜に接触させて、該濾過膜に吸着したノニオン界面活性剤を脱着させる脱着工程とを有するノニオン界面活性剤含有水の処理方法。この処理水を浸透膜処理する水処理方法。
