Efficiency of chitosans for the treatment of papermaking process water by dissolved air flotation

•Papermaking process waters were treated with chitosans in dissolved air flotation.•At neutral pH, native chitosans were more efficient than quaternary derivatives.•A high synergy is obtained when native chitosans are combined with bentonites.•Chitosan dosage can be reduced by half if bentonite is a...
