Initial Corrosion Behavior under Biofilms of Metal Material in Sea Water;

Identification of compositions of the biofilm in a Beijing simulator water distribution system pipe networks by PCR and single strand conformation polymorphism(PCR-SSCP) technique and analysis of its heterotrophic bacterial by heterotrophic plate count(HPC) were performed.

The progress of these techniques and some techniques used in biofilm related problems are discussed.

Research on structure and performance of PVDF microporous membranes via thermally induced phase separation;

Study on the application of microporous membrane filtration in vinegar production;

Effect of the number of carbon atoms in the linear alkyl chain of dialkyl phthalate on polypropylene microporous membrane formation via thermally induced phase separation;

Preparation and characterization of magnetic and thermo-responsive microcapsule membranes;

Progress of research and application of pH-responsive microcapsule membranes;

Experimental investigations were carried out systematically to prepare small-sized, monodispersed and porous microcapsule membranes by using SPG (Shirasu-Porous-Glass) membrane emulsification and interfacial polymerization.

The application of UMWPE micro-filtration membrane technique in vinegar clarification;

Study on wastewater treatment in the middle phase by flocculant micro-filtration membrane;

A hollow fiber micro-filtration membrane of poly(phthalazinone ether sulfone ketone) (PPESK) was chosen to filter the bacteria from soy sauce which is untreated by heat.
