The fouling was evaluated by the increase of transmembrane potential due to the increase of membrane electric resistance caused by biofouling. However, the voltage was not changed for 20h. Then, for further investigation, fouled membranes were...

electric current flows through the system. It is known that, in these systems, anion exchange membranes -AEMs- are most likely affected by fouling. Then, in this study, we attempted to evaluate the effect of direct electric current and field on biofouling...

アニオン交換膜-AEM-及びカチオン交換膜-CEM-としては、それぞれアストム社製のNEOSEPTA AMXおよびNEOSEPTA CMXを用いた。また、モデルバクテリアとしてPseudomonas putida -P. putida-を用いた。EDでは0.05M NaCl濃度のバクテリア懸濁液-O.D.450: 0.5-を源液として2mA/cm2の定電流で実験を行った。REDでは0.5M NaCl濃度のバクテリア懸濁液-O.D.450: ...

ED performance, it is needed to enhance the monovalent anion permselectivity and anti-fouling properties included anti-organic, anti-inorganic and anti-biofouling of anion-exchange membranes -AEMs-. In our previous study, we succeed to improve...

The bio-fouling is any non-desirable accumulation and growth of living matters on the material surfaces. Four grafting agents, Acrylic acid (AA), 2-hydroxyethyl methacrylate (HEMA), 2-dimethyl amino ethyl methacrylate (DMAEMA) and, Methyl acrylate...

Reverse electrodialysis (RED) is an electrochemical process for converting salinity gradient energy into electric energy. Biofouling of anion exchange membranes (AEMs) is a severe problem affecting RED performance. In this study, we examined...

We systematically evaluated the effects of operating conditions on biofouling behaviors in reverse osmosis (RO) membrane processes. The biofouling experiment was performed by filtrating nutrient-containing feed water with a cross-flow cylindrical...

The fouling of anion exchange membranes (AEMs) during an electrodialysis (ED) is a serious problem. Membrane fouling is often classified into organic fouling, inorganic fouling (scaling) and biofouling. In our previous studies, we reduced organic...
