A photocatalytic membrane combining photocatalyst and technology based on polyacrylonitrile (PAN) TiO2/CNT has been developed. Such combination is to overcome fouling formation the membrane, thus prolonging lifetime enhancing efficiency waste treatment. PAN nanofiber was prepared by electrospinning method. The precursor solution dissolved dispersed in N,N-Dimethylformamide (DMF). concentration ...

The development of nanofiltration membranes with hollow fiber geometry is a relatively young field research in membrane science only limited, but quickly growing, availability on commercial scale. These offer promising properties for application water treatment such as high fouling resistance and low cost compared to Reverse Osmosis membranes. Major differences are found dimension operating con...

Water treatment is regarded as one of the essential elements sustainability. To lower cost treatment, wastewater volume reduced via osmotic process. Here, mixed-matrix woven forward osmosis (MMWFO) PES membranes modified by a TiO2/Na2Ti3O7 (TNT) nanocomposite were fabricated for treating water from different sources. Various techniques used to characterize TNT nanocomposite. The crystal structu...

Membrane fouling encountered in reclamation of municipal wastewater represents serious design and operational concern. Fouling occurs because the municipal effluent, after secondary treatment, contains high concentrations of suspended particles, colloids and high level of biological activity. Application of membrane technology for treatment of municipal wastewater requires very extensive pretre...

PURPOSE To correlate clinical and optical coherence tomographic (OCT) features with morphologic and immunohistochemical findings of epiretinal membranes (ERMs) in lamellar macular holes (LMHs). METHODS Nineteen specimens were removed from 19 eyes during vitrectomy for lamellar macular hole with ERM and internal limiting membrane peeling, and were processed for transmission electron microscopy...

We have surveyed the high-mass Galactic star-forming regions G19.61 0.23, G45.47+0.05, and W75N for interstellar methanol (CH3OH), formic acid (HCOOH), acetic acid (CH3COOH), methyl formate (HCOOCH3), methyl cyanide (CH3CN), and ethyl cyanide (CH3CH2CN) with the Berkeley-Illinois-Maryland Association Array. From our observations, we have detected two new sources of interstellar HCOOH toward the...

We present the first detection of interstellar acetone [(CH3)2CO] toward the high mass star forming region Orion-KL and the first detection of vibrationally excited (CH3)2CO in the ISM. Using the BIMA Array, 28 emission features that can be assigned to 54 acetone transitions were detected. Furthermore, 37 of these transitions have not been previously observed in the ISM. The observations also s...

Polyepoxysuccinic acid (PESA) is a green corrosion scale inhibitor. When PESA is used for wastewater desalination in the forward osmosis (FO) process, the diluted PESA solution could be used for cooling systems. In our investigation, the effects of membrane orientation, temperature and flow rate on FO performance are studied using PESA as a draw solute. The results show that the effect of tempe...
