Much work has been done on the dyeing water treatment by a new method of the combination of crossflow microfiltration, flocculation and ceramic membrane technique with some successful results caused by the advantages of the combination. The kind of flocculation and its dosage are studied, which is u

An amphoteric chitosan derivative, containing carboxymethyl (–COOH) groups and amine (–NH2) groups, had been prepared. FT-IR spectra confirmed the presence of γsymCOO (1408 cm–1) and γasCOO (1584 cm–1) on the structural units of the chitosan derivative, and 13C NMR spectra revealed that carboxy meth

A membrane distillation process with brine circulated in the cold side was developed. This process combines the ordinary membrane distillation (MD) with the osmotic distillation (OD), and is therefore called membrane osmotic distillation (MOD). Comparisons of MOD with MD and OD were carried out. It
