Antibacterial activity of chitosans and chitosan oligomers with different molecular weights.
TL;DR: Antibacterial activities of chitosan was inversely affected by pH (pH 4.5-5.9 range tested), with higher activity at lower pH value, and bactericidal effects with gram-positive bacteria than gram-negative bacteria in the presence of 0.1% chitOSan.

Chitosan for coagulation/flocculation processes. An eco-friendly approach.
TL;DR: In this paper, an overview of the main results obtained in the treatment of various suspensions and solutions is given, and the effects of the characteristics of the chitosan used and the conditions in solution on the coagulation/flocculation performance are also discussed.

Flocculation of kaolinite suspensions in water by chitosan.
TL;DR: Flocculation is faster at higher concentrations of kaolinite and the flocs are large and settle rapidly, and flocculation efficiency is very sensitive to pH, and reaches a maximum at pH 7.5.
Journal ArticleDOI
Flocculation of river silt using chitosan
TL;DR: Flocculation of silt in river water using chitosan was studied in the pH range 4-9, and suspended solid concentrations in the range 20-80 mg/L and the amount required for restabilisation increases with increasing concentration of suspended solids.

Characteristics of Poultry Processing Effluent
TL;DR: In this paper, the authors analyzed raw effluents from four broiler processing plants for BOD5, suspended solids, pH, and dissolved oxygen, and found that the variability was greatest in dissolved oxygen and least in pH.
