The morphology and structure of PVA-MS/PCDMs were examined using scanning electron microscope (SEM),and approximate maximal separated aperture,water contact angle,pure water permeation resistance and relative Zeta potential of the membrance surface were also determined.

Study on the filtration resistance of inorganic microfiltration membrane;

Performance of hybrid membrane bioreactor(HMBR) with suspended carriers during long-term operation was studied under the lab conditions in such aspects as COD removal efficiency,transmembrane pressure(TMP),sludge particle size distribution and filtration resistances of sludge suspension.

Average filtration resistance increase rate(K) over the operation time was introduced to evaluate membrane fouling.

Describes the straight cylinder type strainer and considers it as better than Y type strainer in maximizing the filtration area, ensuring the water flow direction, minimizing the filtering resistance and considerations for the cost and maintenance.

The modified MBR and non-modified MBR were applied to treat the wastewater,and the effluent quality,membrane flux and membrane filtration resistance were compared.

The effect of powdered activated carbon(PAC) on the mixed liquor characteristics and membrane filtration resistance was studied by using two membrane bioreactors(Reactor 1 no PAC and Reactor 2 added PAC 500 mg/L)under the same influent and operating conditions.

A method for evaluating the drainage properties of pulp with specific filtration resistance is introduced.
