Preparation and application of a new composite chitosan flocculant
A new composite chitosan flocculant has been prepared, and its optimal dosage in the treatment of sewage established. It significantly improves the removal of chemical oxygen demand, suspended solids and aluminium ions from water. Compared with the traditional flocculant polyaluminium chloride, the cost of the composite flocculant was lower and it produced less pollution.Keywords: chitosan, ...

Zirconium and chitosan coagulants for drinking water treatment – a pilot study
Scientists continuously search for alternative coagulants that would be able to outperform traditionally used aluminium (Al) and iron (Fe). Use of a novel metal coagulant zirconium (Zr) has been associated with enhanced organic matter reduction. On the other hand, eco-friendly non-metal solutions, such as chitosan, can provide non-toxic sludge and water with no metal residue. In fact, Zr and ...

Evaluation of chitosan as a natural coagulant for drinking water treatment
Chitosan, a natural biopolymer, was evaluated for its ability to be used as a coagulant to treat water for potable use both in isolation and in combination with other water treatment technologies, specifically ion-exchange and activated carbon. Chitosan was found to be very effective for particle removal at doses far below those required for equivalent turbidity removal by inorganic coagulants. ...
