Photocatalytic Membrane Reactor

The objectives of the current study are to assess and compare the performance of a developed photocatalytic membrane reactor (PMR) in treating industrial waste (e.g., organic dye waste) against membrane distillation. The current PMR is composed of a feed tank, which is a continuous stirred photocatalytic reactor containing slurry Titanium dioxide (TiO2) particles that are activated by using ultraviolet lamp irradiation at a wavelength of 365 nm, and a poly-vinylidene flouride (PVDF) membrane cell. The experimental setup was designed in a flexible way to enable both separate and integrated investigations of the photocatalytic reactor and the membrane, separately and simultaneously. The experimental work was divided into two phases. Firstly, the PVDF membrane was fabricated and characterized to examine its morphology, surface charge, and hydrophobicity by using a scanning electron microscope, surface zeta potential, and contact angle tests, respectively. Secondly, the effects of using different concentrations of the TiO2 photocatalyst and feed (e.g., dye concentration) were examined. It is found that the PMR can achieve almost 100% dye removal and pure permeate is obtained at certain conditions. Additionally, a kinetic analysis was performed and revealed that the photocatalytic degradation of dye follows a pseudo-first-order reaction.

AbstractIn highly purified bc1-complex from baker’s yeast, the reduction of cyt c1 and partial reduction of cyt b is obtained by catalytic amount of succinate dehydrogenase and succinate in the presence of 7 μᴍ antimycin. After the addition of ferricyanide the c1 is re-oxidized and a increase in the reduction of b is observed. Using stopped-flow we established that the oxidation of c1 by ferricyanide proceeds as a pseudo-first order reaction and the reduction of b is faster and with two phases. Our observation suggests that these two processes are not directly interconected and that other component than c1 must be the “control factor” in the anomalous reduction of cyt b. This component must be, by exclusion, the iron-sulfur protein.

Photocatalytic Membrane Reactor

Membrane separation coupled with photocatalysis process, which is also called photocatalytic membrane reactor (PMR), is a new hybrid technology working for water supply and wastewater treatment. Due to some unique advantages, such as nontoxic and continuous running, this kind of novel coupling systems has developed rapidly in the past few years. In this work, the characteristic and structure of configurations, photocatalysts and membranes are analyzed briefly.
