Hematite wastewater containing dissolved heavy metals is a potential threat to eco-
environment and human health. Flocculation as an efficient and cost effective water …

A novel chelating flocculant with branched architectures, polyacrylamide grafted maleoyl
chitosan-mercaptoacetic acid (PAM-gM (CS-MA)), was successfully fabricated using maleic …

In order to effectively remove the dissolved heavy metals and the heavy metals on the
colloidal particles during the flocculation process, a novel dual-functional chitosan flocculant …

In this work, a novel chitosan-based flocculant, carboxymethyl chitosan-graft-poly [(2-
methacryloyloxyethyl) trimethyl ammonium chloride](CMC-g-PDMC), was designed and …

A novel macromolecular heavy metal chelating flocculant, xanthated chitosan (XCTS), was
prepared by reacting chitosan with benzaldehyde, NaOH and CS 2. In a series of …

The chitosan is a good flocculant for tap water treatment because of its properties such as
faster deposition rate and higher removal efficiency for COD (organic matter), SS …

Flocculation is a water and wastewater treatment technology whereby the large aggregation
of flocs in water can be formed and be later separated through sedimentation. This review …

BACKGROUND Contaminants with either negative or positive surface charges in
wastewater generated from oilfields are normally very difficult to remove by traditional …

To solve the shortcomings of poor solubility, low cationic strength, and small molecular
weight of chitosan (CTS), acryloyloxyethyl trimethyl ammonium chloride (DAC) and 2 …

Abstract k] In this study, the coagulating effect of a novel composite flocculant on treating
papermaking wastewater was studied and discussed. Results indicated that it achieved the …
