Enhanced removal of suspended colloidal particles from turbid water using a modified microbial flocculant

Microbial flocculant (MBF), as an efficient, environmental friendly and biodegradable flocculant, has been widely studied in water treatment. The cationic modification of MBF would improve its charge neutralization and extend its application. In this study, the effect of mAM:mDMDAAC, mMBF:m(AM + DMD...

Description
Summary:Microbial flocculant (MBF), as an efficient, environmental friendly and biodegradable flocculant, has been widely studied in water treatment. The cationic modification of MBF would improve its charge neutralization and extend its application. In this study, the effect of mAM:mDMDAAC, mMBF:m(AM + DMDAAC), reaction temperature and initiator dosage on the molecular weight of modified MBF were investigated. The optimal synthesis condition was obtained. Modified MBF performed well in the removal of suspended colloidal particles from water. It possessed the potential application in the surface water treatment.
