Abstract For ultrafiltration, and membrane filtration more generally, the quantitative determination of modes fouling remains a subject great interest. Herein an integral method for determining from time series volumetric flux $$J\left(t\right)$$ J t </...

In Malaysia, the quality of groundwater as one main sources drinking water is deteriorated due to presence a high level manganese, which exceeds allowable values for consumption. Manganese at concentration higher than 0.1 mg/L causes staining, turbidity and bad taste problem in water, eventually can cause depletion brain dopamine syndrome motor dysfunction memory loss resembling Parkinson disea...

In the current research, ABS-co-PEG nanofiltration membrane was prepared by solution casting technique using N, N dimethyl acetamide as solvent. The effect of PEG concentration as additive in the casting solution on membrane flux, salt rejection, phase inversion time, water content, membrane porosity, membrane tensile strength and fouling was studied. Also the eff...

Nanofiltration is increasingly gaining attention in many separation and treatment processes such as water softening, color removal and separation of medicines. Nanofiltration membranes are often negatively charged, displaying separation characteristics in the intermediate range between reverse osmosis and ultrafiltration. In this research, a novel nanofiltration membrane prepared with poly(amid...

AIMS To investigate the optimal method for the detection of campylobacters from stool samples by comparing selective culture with membrane filtration and the polymerase chain reaction (PCR). METHODS Three hundred and forty three stool samples were investigated by each of the three methods mentioned above. Selective culture was performed with charcoal cefoperazone desoxycholate agar plates. Me...

CHROMagar Candida medium was inoculated with a variety of clinical samples (n = 282) by using membrane filtration instead of swabbing or streaking. This modified CHROMagar procedure increased the ability to detect yeast by 16.7%. Compared to an enzymatic two-step membrane filtration method with fluorogenic substrates, it yielded similar recovery but was slower.
